ASIA VITAL COMPONENTS CO., LTD.,

Plaintiff,

v.

ASETEK DANMARK A/S,

Defendant.

Case No. 16-cv-07160-JST 

ORDER RE: CROSS-MOTIONS FOR 

PARTIAL SUMMARY JUDGMENT

AND MOTION TO STRIKE

Re: ECF Nos. 180, 185, 186

Before the Court are cross-motions for partial summary judgment filed by 

Plaintiff/Counter-Defendant Asia Vital Components Co. (“AVC”) and Defendant/CounterClaimant Asetek Danmark A/S. ECF Nos. 180, 186. Asetek has also filed several requests to 

strike. ECF No. 185. The Court will grant the motions to strike in part, grant Asetek’s motion for 

partial summary judgment, and deny AVC’s motion for partial summary judgment.1

I. BACKGROUND

The Court briefly sets out the nature and history of this dispute, then reviews the factual 

record in greater detail where relevant below.

2

 This case concerns two patents, held by Asetek, 

that describe a liquid cooling device for the central processing unit of a computer: U.S. Patent 

Nos. 8,240,362 (“the ’362 patent”) and 8,245,764 (“the ’764 patent”). ECF Nos. 180-13, 180-14. 

 

1 The Court has filed this order under seal because it contains material subject to sealing orders. 

Within seven days of the filing date of this order, the parties shall provide the Court a stipulated 

redacted version of this order, redacting only those portions of the order containing or referring to 

material for which the Court has granted a motion to seal and for which the parties still request the 

material be sealed. The Court will then issue a redacted version of the order.

2 Given the parties’ cross-motions for summary judgment, the Court presents the facts herein so 

far as they are undisputed. Where relevant to a contested issue, the Court construes them below in 

the light most favorable to the non-movant.

United States District Court

Northern District of California

Claim 1 of the ’362 patent is illustrative:

1. A cooling system for a computer processing unit, comprising:

an integrated element including a heat exchanging interface, a reservoir, and a 

pump, wherein 

the reservoir is configured to receive a cooling liquid from outside the reservoir 

through an inlet and pass the cooling liquid to the outside through an outlet, 

the reservoir including an upper chamber and a lower chamber, the upper 

chamber and the lower chamber being vertically displaced chambers that 

are separated by at least a horizontal wall and fluidly coupled together by a 

plurality of substantially circular passages, at least one of the plurality of 

substantially circular passages being positioned on the horizontal wall, a 

boundary wall of the lower chamber being formed by the heat exchanging 

interface;

the heat exchanging interface is adapted to provide separable thermal contact 

between the processing unit and the cooling liquid such that heat is 

dissipated from the processing unit to the cooling liquid as the cooling liquid 

passes through the lower chamber of the reservoir; and

the pump is adapted to direct the cooling liquid through the upper chamber and 

the lower chamber of the reservoir, the pump including a motor having a 

rotor, a stator and an impeller having a plurality of curved blades, the 

impeller being positioned within the reservoir;

a heat radiator spaced apart from the integrated element, the heat radiator being 

fluidly coupled to the outlet and the inlet of the reservoir, the heat radiator being 

configured to circulate the cooling liquid therethrough and exhaust heat from 

the cooling liquid; and

a fan configured to direct air through the heat radiator, the fan being driven by a 

motor separate from the motor of the pump.

ECF No. 180-13 at 18:50-19:18.

The patents issued on August 14, 2012, and August 21, 2012, respectively. ECF No. 180-

13 at 2; ECF No. 180-14 at 2. Asetek then filed two separate actions in this district against 

different entities (who are not parties to this action), asserting that their products infringed the 

patents. See Asetek Holdings, Inc. v. Coolit Sys. Inc., 12-cv-04498-EMC, ECF No. 1 (August 27, 

2012); Asetek Danmark A/S v. CMI USA, Inc., 13-cv-00457-JST, ECF No. 1 (January 31, 2013).

The parties agree that Asetek sent a letter to AVC dated April 30, 2014, alleging that the 

Liqmax 120 product and related products – sold by one of AVC’s customers, Enermax – also 

infringed the patents. ECF No. 1 ¶ 22; ECF No. 186 at 20; ECF No. 203-12 at 2. After additional 

correspondence in which AVC apparently responded that it had no relationship to the Liqmax

products identified, Asetek sent an email to AVC on August 2, 2014, informing AVC of its belief 

that “AVC is likely selling other infringing products in the United States.” ECF No. 203-12 at 2. 

Asetek’s CEO testified that, in a subsequent meeting, AVC attempted to obtain a license for the 

patents. ECF No. 202-7 at 241:20-243-10. AVC does not dispute that the meeting took place.

On September 30, 2014, AVC filed a complaint in the U.S. District Court for the Eastern 

District of Virginia, requesting declaratory relief that its products – which it designated as the K7 

and K9 products – did not infringe the ’362 or ’764 patents. See ECF No. 1. AVC claimed that 

(1) the products did not infringe the patents-in-suit; and (2) the patents-in-suit were invalid. See 

id. After proceedings not directly relevant here, the case was transferred to this Court in 

December 2016. ECF No. 37. 

On July 14, 2017, Asetek filed counter-claims for direct, induced, contributory, and willful 

infringement, alleging that at least the AVC K7127N, K7 1.5, and K9, and Riotoro Bifrost 

120Ti/240 products infringed the ’362 and ’764 patents. See ECF No. 73. On January 17, 2018, 

the Court issued its claim construction order. ECF No. 105. Asetek subsequently amended its 

infringement contentions to cover the AVC 1.5, 2.0, K7127N, and K9 products (the “accused 

products”). See ECF Nos. 125, 130.

On November 30, 2018, Asetek filed a motion for partial summary judgment on AVC’s 

invalidity and equitable defenses. ECF No. 180. Asetek also filed a motion to strike portions of 

AVC’s expert’s non-infringement report. ECF No. 185. AVC filed a cross-motion for partial 

summary judgment on December 6, 2018, on a series of issues, including its liability for induced, 

contributory, or willful infringement, as well questions related to extraterritorial sales and Asetek’s 

compliance with product marking requirements. ECF No. 186.

II. EVIDENTIARY OBJECTIONS

Asetek has filed a separate motion to strike portions of Dr. Clarksean’s rebuttal noninfringement report. ECF No. 185. In the course of briefing on the motions for summary 

judgment, Asetek also requested that the Court strike Dr. Clarksean’s declaration attached in 

support of AVC’s motion for summary judgment, ECF No. 203 at 20-23, and Dr. Joshi’s 

declaration attached in support of AVC’s opposition to Asetek’s motion for summary judgment,

ECF No. 205 at 5-8. The Court resolves these disputes before reaching the merits of the parties’ 

summary judgment motions.

A. Legal Standard

Federal Rule of Civil Procedure 26(a)(2)(B) requires a witness who is “retained or 

specially employed to provide expert testimony in the case” to provide a written report containing, 

among other things, “(i) a complete statement of all opinions the witness will express and the basis 

and reasons for them,” and “(ii) the facts or data considered by the witness in forming them.” Fed. 

R. Civ. P. 26(a)(2)(B). In addition, Rule 26(e)(1) imposes an obligation on a party “who has 

responded to an interrogatory” to “supplement or correct its disclosure or response (A) in a timely 

manner if the party learns that in some material respect the disclosure or response is incomplete or 

incorrect, and if the additional or corrective information has not otherwise been made known to 

the other parties during the discovery process or in writing.” Fed. R. Civ. P. 26(e)(1).

Rule 37, in turn, “gives teeth to Rule 26’s disclosure requirements by forbidding the use at 

trial of any information that is not properly disclosed.” Goodman v. Staples The Office 

Superstore, LLC, 644 F.3d 817, 827 (9th Cir. 2011) (internal quotation marks and citation 

omitted).3 Rule 37(c)(1) thus requires exclusion unless the offending party carries its burden “to 

demonstrate that the failure to comply with Rule 26(a) is substantially justified or harmless.” 

Torres v. City of Los Angeles, 548 F.3d 1197, 1213 (9th Cir. 2008). For instance, where an expert 

fails to provide a theory in the report, a court may “preclud[e] him from testifying on this issue.” 

Nationwide Transp. Fin. v. Cass Info. Sys., Inc., 523 F.3d 1051, 1062 (9th Cir. 2008); see also 

Paladin Assocs., Inc. v. Montana Power Co., 328 F.3d 1145, 1164 (9th Cir. 2003) (applying Rule 

37(c)(1) where “expert witnesses submitted affidavits that contained new opinions not previously 

disclosed as required by Federal Rule of Civil Procedure 26(a)(2)(B)”); Hoffman v. Constr. 

Protective Servs., Inc., 541 F.3d 1175, 1179 (9th Cir. 2008) (applying Rule 37(c)(1) to a violation 

of Rule 26(e)(1)(A)).

 

3 Because “[a] decision to sanction a litigant pursuant to Fed.R.Civ.P. 37 is one that is not unique 

to patent law,” the Court applies Ninth Circuit precedent to these issues. ClearValue, Inc. v. Pearl 

River Polymers, Inc., 560 F.3d 1291, 1304 (Fed. Cir. 2009) (citation omitted).

B. Dr. Clarksean’s Rebuttal Non-Infringement Report

Asetek requests that the Court strike from Dr. Clarksean’s report the theory that the K9 and 

M5 products do not infringe the ’764 patent because the pump stator of those products is not 

“isolated from the cooling liquid.” ECF No. 185 at 6. Asetek argues that AVC failed to disclose 

this theory in its answer to Asetek’s August 2, 2017 interrogatory requesting the factual and legal 

bases for AVC’s non-infringement contentions. See ECF No. 185-2 at 3-4; ECF No. 185-3. 

Instead, Asetek contends, AVC advanced this theory for the first time in Dr. Clarksean’s rebuttal 

report, which it served on October 26, 2018. ECF No. 185 at 8; ECF No. 185-1 ¶ 9.

In its opposition, AVC first argues that it was not required to supplement its interrogatory 

response with these details, and therefore did not violate Rule 26(e)(1). ECF No. 199 at 10-11, 13. 

AVC reasons that, because Asetek bears the burden of proof on the question of infringement, 

AVC did not need to “divulge its fully-crystallized non-infringement arguments upon which [it] 

would rely at trial, because the deadline for AVC’s rebuttal expert report on non-infringement 

served that purpose.” ECF No. 199 at 13. 

The parties rely on cases from this district suggesting opposite conclusions. AVC cites 

MediaTek Inc. v. Freescale Semiconductor, Inc., where the court rejected a request to strike 

validity theories that were provided in an expert rebuttal report, but not disclosed in response to an 

earlier interrogatory. No. 11-CV-5341-YGR, 2014 WL 2854773, at *4 (N.D. Cal. June 20, 2014). 

The MediaTek court reasoned that, “by propounding [its] interrogatory right on the heels of 

serving its invalidity contentions, [the accused infringer] was trying to get a preview of what [the 

patentee’s] rebuttal report would say.” Id. at *5. Deeming this “gamesmanship,” the court stated 

that it would “not penalize [the patentee] for providing its response – its expert rebuttal report – at 

the time appointed by the Court’s scheduling order.” Id.

Asetek, on the other hand, relies on Apple, Inc. v. Samsung Elecs. Co., where the court 

granted a similar request to the one Asetek makes here, faulting Samsung for its “failure to 

disclose its non-infringement theories prior to the rebuttal expert reports,” given that Samsung 

“had a duty to amend its answers to contention interrogatories in a timely manner.” No. 11-CVCase 3:16-cv-07160-JST Document 241 Filed 03/26/19 Page 5 of 40

01846-LHK, 2012 WL 3155574, at *5 (N.D. Cal. Aug. 2, 2012).4 

The Court finds the rule set forth in Samsung more persuasive. A rule that an accused 

infringer may wait until its expert rebuttal report to set forth theories of non-infringement for the 

first time would forfeit the benefits of contention interrogatories. As the Federal Circuit has 

explained, such interrogatories “serve an important purpose in helping to discover facts supporting 

the theories of the parties. Answers to contention interrogatories also serve to narrow and sharpen 

the issues thereby confining discovery and simplifying trial preparation.” Woods v. DeAngelo 

Marine Exhaust, Inc., 692 F.3d 1272, 1280 (Fed. Cir. 2012). Because “answers to contention 

interrogatories evolve over time as theories of liability and defense begin to take shape . . . . Rule 

26(e) requires that as theories mature and as the relevance of various items of evidence changes, 

responses to interrogatories, and particularly contention interrogatories, be corrected or 

supplemented to reflect those changes.” Id. The Court finds nothing in the text of this district’s 

patent rules relieving parties arguing non-infringement of that obligation. Rather, the rules were 

“designed to require parties to crystallize their theories of the case early in the litigation and to 

adhere to those theories once they have been disclosed” – not defer the disclosure of those theories 

until the expert rebuttal stage. MLC Intellectual Prop., LLC v. Micron Tech., Inc., No. 14-CV03657-SI, 2018 WL 6046465, at *2 (N.D. Cal. Nov. 19, 2018) (quoting O2 Micro Int’l Ltd. v. 

Monolithic Power Sys., Inc., 467 F.3d 1355, 1366 n.12 (Fed. Cir. 2006)).

The Court next turns to AVC’s arguments that it did not violate Rule 26(e)(1) because the 

information was conveyed to Asetek through alternate means. AVC asserts that it satisfied its 

obligations by providing physical copies of the K9 and M5 products in a timely manner. ECF No. 

199 at 11. AVC cites no support for this position and, in any event, providing an example of the 

accused product plainly does not substitute for answering a contention interrogatory. Cf. Woods, 

692 F.3d at 1280. AVC likewise cannot fulfill its obligation by now point to a single table 

 

4 Asetek attempts to distinguish MediaTek on the basis that it involved invalidity and a patent’s 

validity is presumed, while there is no corresponding presumption of non-infringement applicable 

in Samsung or here. ECF No. 206 at 6. The Court does not read MediaTek to rely on the 

presumption of patent validity to any significant degree, and accordingly is unable to reconcile 

that case with Samsung.

indicating that the K9 had a submersible pump, ECF No. 200-4 at 2, which was not produced in 

response to the interrogatory. The post-hoc identification of a needle in a haystack does not cure 

AVC’s failure to respond. See Apple, Inc., 2012 WL 3155574, at *5.

Next, AVC points to its Rule 30(b)(6) witness’s deposition testimony on September 18 and 

19, 2018. ECF No. 199 at 12. Assuming without deciding that this testimony could ever suffice

to meet AVC’s discovery obligations, the Court finds that it does not do so in this instance. 

Huang stated that the K9 differed from the 1.5 product because it “uses an immersive pump.” 

ECF No. 183-4 at 101:24-102:2. When asked to explain the term “immersive pump,” Huang

responded, “I’m not – I don’t know the detailed technology” and gave no additional explanation. 

Id. at 102:20-22. This exchange does not disclose in any discernible manner the basis for Dr. 

Clarksean’s theory. In addition, AVC mischaracterizes Asetek’s motion as conceding that Asetek

gleaned this theory from Huang’s testimony. ECF No. 199 at 12. Asetek offered unrebutted 

evidence that it did not understand AVC’s position at the time, see ECF No. 185-1 ¶ 11, and stated 

that once it received Dr. Clarksean’s rebuttal report, it understood Huang’s testimony as revealing 

that “AVC intended to argue, even when it was developing its products, that the K9 and M5 do not 

infringe” based on the theory at issue. ECF No. 185 at 12. The thrust of this discussion is when 

AVC knew of its own theory, not when Asetek came to understand it. 

The Court further agrees with Asetek that Huang’s testimony that AVC used this “entirely 

different pump” to “try to design around Asetek’s patents” provides unrebutted evidence that AVC 

was fully aware of this theory at the time it received the interrogatory. ECF No. 183-4 at 120:2-4; 

120:20-22. Accordingly, AVC cannot claim that it did not discover this theory until it received 

Dr. Tilton’s infringement report. ECF No. 199 at 13.

The Court therefore concludes that AVC violated its Rule 26(e)(1) obligations by failing to 

disclose its theory in response to Asetek’s contention interrogatory. 

The Court further finds that AVC has not carried its burden to demonstrate that its failure 

was not “substantially justified or harmless.” Torres, 548 F.3d at 1213 (emphasis omitted) 

(quoting Fed. R. Civ. P. 37(c)(1)). As just noted, the record reveals that AVC has been aware of 

this theory since the outset of this litigation. AVC offers no justification for failing to include it in

its interrogatory responses, but instead attempts to show that other actions conveyed the same 

information, i.e., that its failure was harmless. As explained above, AVC’s argument that it had 

no obligation to supplement its responses lacks merit. Therefore, AVC’s conduct was not 

substantially justified.

Nor was it harmless. By waiting until its expert rebuttal report to disclose its theory, AVC 

prevented Asetek from conducting fact discovery on the issue, thereby hampering its expert 

discovery as well. See Apple, Inc., 2012 WL 3155574, at *5 (“Although expert discovery had not 

yet concluded, the experts were in effect locked-in to the factual record as of the time fact 

discovery closed and could not test the factual basis for the newly amended contentions by 

conducting additional discovery.”). It also deprived Asetek of the ability to fully question AVC’s 

deposition witnesses on the subject. 

The factors that AVC cites do not overcome this prejudice. AVC did not give Asetek prior 

notice of its position through other means, as discussed above. AVC’s reliance on Dr. Tilton’s 

ability to locate the stator when asked in his deposition, ECF No. 199 at 16-17, is not responsive to 

the material dispute identified by Asetek as to what portions of the accused products actually 

constitute the “stator.” ECF No. 185 at 13. It is no answer, as AVC suggests, ECF No. 199 at 18, 

that Asetek can request leave to submit a supplemental expert report. See K. P. v. Santa Clara 

Cty. Office of Educ., No. 5:15-CV-01512-EJD, 2016 WL 5930641, at *3 (N.D. Cal. Oct. 12, 2016) 

(“Defendants cannot just blithely offer a schedule modification and expect Plaintiffs to accept it as 

a way to alleviate the problem they created and the prejudice they inflicted.”). Finally, while AVC 

argues that its theory is important to its case, it has other non-infringement theories for these same 

claims. See ECF No. 185-1 ¶¶ 9-10.

5

 

Accordingly, the Court grants Asetek’s motion to strike the disputed theory from Dr. 

Clarksean’s expert rebuttal non-infringement report.

 

5 Accordingly, the Court need not “consider whether the claimed noncompliance involved 

willfulness, fault, or bad faith” or “the availability of lesser sanctions.” R & R Sails, Inc. v. Ins. 

Co. of Penn., 673 F.3d 1240, 1247 (9th Cir. 2012).

C. Dr. Joshi’s Declaration

In support of its opposition to summary judgment, AVC attached a declaration from Dr. 

Joshi, the author of AVC’s expert invalidity report. ECF No. 194-1. On reply, Asetek requests 

that the Court strike new opinions and theories introduced in Joshi’s declaration. ECF No. 205 at 

5-8. AVC did not request leave to file a sur-reply or otherwise oppose this request.

The Court first considers whether the Joshi declaration goes beyond “a reasonable 

synthesis and/or elaboration of the opinions contained in [his] report.” LivePerson, Inc. v. 

[24]7.AI, Inc., No. 17-CV-01268-JST, 2018 WL 6257460, at *1 (N.D. Cal. Nov. 30, 2018) 

(citation omitted); see also Fujifilm Corp. v. Motorola Mobility LLC, No. 12-CV-03587-WHO, 

2015 WL 12622055, at *4 (N.D. Cal. Mar. 19, 2015) (same). 

To the extent the Joshi declaration opines that there were general industry-level trends “to 

increase the effectiveness and minimize the volume of the heat dissipation module in the field of 

thermal management,” ECF No. 194-1 ¶ 2, the Court finds that it is a reasonable synthesis of the 

background sections of his invalidity report, see ECF No. 180-2 at 9-11; ECF No. 180-4 at 9-11. 

But the Joshi declaration goes much further, stating his opinion that pursuit of this 

“miniaturization” or “integration” goal would have motivated a person of ordinary skill in the art 

to combine prior art references in the specific combinations set forth in the remainder of his expert 

report. See ECF No. 194-1 ¶¶ 2-8, 12-14, 17-19, 26-29. There is simply no corresponding 

discussion of miniaturization as applied to any prior art in Dr. Joshi’s report. This absence is 

underscored by the fact that the Joshi declaration makes no attempt to link its contents to any 

specific discussion in the report, instead citing to the portions of Dr. Joshi’s deposition testimony 

that are helpful to AVC. See id. ¶¶ 3-6.6 The Court finds that these opinions impermissibly 

exceed the scope of Dr. Joshi’s expert report.

The Joshi declaration also opines on whether various prior art references disclose certain 

limitations of the patents-in-suit. As this Court has previously held, an invalidity report must be 

 

6 As Asetek notes, Dr. Joshi first testified that his report contained “no motivation or rationale” for 

any of the asserted combinations. ECF No. 180-7 at 73:17-79:9. On redirect, however, Dr. Joshi 

testified that a miniaturization rationale applied to each prior art reference. Id. at 164:21-166:10.

specific as to which item of the prior art discloses which element of the disputed claim. Asetek 

Danmark A/S v. CMI USA, Inc., No. 13-CV-00457-JST, 2014 WL 6997670, at *1 (N.D. Cal. Dec. 

9, 2014) (striking post-report testimony that a new item of the prior art disclosed a thermal 

exchange chamber). It is difficult to see how, absent some clarifying function, Dr. Joshi’s 

opinions regarding the connection between the prior art references and claim limitations, id. ¶¶ 10-

16, 23-25, are not either unnecessarily redundant with his expert report or impermissibly beyond 

its scope.

The Court perceives only one such potential ambiguity. Dr. Joshi’s expert report uses the 

following diagram from Schmidt7:

See ECF No. 180-2 at 35; ECF No. 180-4 at 29; ECF No. 180-20 at Fig. 1. The diagram displays

two labeled vertical supply manifolds (32), each of which has connected horizontal bars. The 

horizontal bars attached to the righthand manifold are labeled as atomizer plates (34), while the 

opposing set of horizontal bars are not. Nonetheless, a review of Schmidt suggests that both sets 

are intended to represent atomizer plates. See ECF No. 180-20 at 2:63-65 (“The supply manifolds 

32 have an atomizer plate 34 in communication with each outlet of the supply manifold . . . .”). 

Dr. Joshi’s expert report, however, at times treats the letfhand set as “horizontal portion[s] . . . of 

the supply manifolds 32” rather than as a separate item. ECF No. 180-2 at 35; ECF No. 180-4 at 

29. Arguably, then, Dr. Joshi’s designation of the supply manifolds (32) as a heat exchange 

“chamber” – as depicted in his report – encompasses the atomizer plates (34).

As to the remaining opinions in the Joshi declaration, AVC has provided no explanation 

why their omission from Dr. Joshi’s report were either substantially justified or harmless, and so 

by default it has not carried its burden. See Torres, 548 F.3d at 1213. Moreover, it is doubtful that 

these failures were substantially justified given that AVC had access to all the relevant information 

regarding the patents and prior art at the time Dr. Joshi submitted his report. Nor can AVC show 

that it was harmless to add new theories in support of its invalidity claims at summary judgment, 

particularly now that discovery has closed. See Rowe Int’l Corp. v. Ecast, Inc., 586 F. Supp. 2d 

924, 938 (N.D. Ill. 2008).

Accordingly, the Court strikes the entire Joshi declaration except its opinions that (1) 

miniaturization is a generally applicable industry trend and (2) Schmidt’s atomizer plates (34) 

disclose a heat exchange chamber.

D. Dr. Clarksean’s Declaration

As discussed below, even were the Court to consider the challenged opinions in Dr. 

Clarksean’s declaration, ECF No. 186-2, it would still deny AVC’s motion for summary judgment 

on those points. The Court therefore denies Asetek’s request as moot.

III. LEGAL STANDARD FOR SUMMARY JUDGMENT

Summary judgment is proper when a “movant shows that there is no genuine dispute as to 

any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). 

A dispute is genuine only if there is sufficient evidence for a reasonable trier of fact to resolve the 

issue in the nonmovant’s favor, and a fact is material only if it might affect the outcome of the 

case. Fresno Motors, LLC v. Mercedes Benz USA, LLC, 771 F.3d 1119, 1125 (9th Cir. 2014) 

(citing Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248-49 (1986)). The court must draw all 

reasonable inferences in the light most favorable to the nonmoving party. Johnson v. Rancho 

Santiago Cmty. Coll. Dist., 623 F.3d 1011, 1018 (9th Cir. 2010).

Where the party moving for summary judgment would bear the burden of proof at trial, 

that party “has the initial burden of establishing the absence of a genuine issue of fact on each 

issue material to its case.” C.A.R. Transp. Brokerage Co. v. Darden Rests., Inc., 213 F.3d 474, 

480 (9th Cir. 2000). Where the party moving for summary judgment would not bear the burden of

proof at trial, that party “must either produce evidence negating an essential element of the 

nonmoving party’s claim or defense or show that the nonmoving party does not have enough 

evidence of an essential element to carry its ultimate burden of persuasion at trial.” Nissan Fire & 

Marine Ins. Co. v. Fritz Cos., 210 F.3d 1099, 1102 (9th Cir. 2000). If the moving party satisfies 

its initial burden of production, the nonmoving party must produce admissible evidence to show 

that a genuine issue of material fact exists. Id. at 1102-03. If the nonmoving party fails to make 

this showing, the moving party is entitled to summary judgment. Celotex Corp. v. Catrett, 477 

U.S. 317, 322-23 (1986).

These standards apply equally to summary judgment motions involving patent claims. See 

Union Carbide Corp. v. Am. Can Co., 724 F.2d 1567, 1571 (Fed. Cir. 1984).

IV. ASETEK’S MOTION FOR SUMMARY JUDGMENT

Asetek moves for summary judgment that (1) claims 1-19 of the ’362 patent are not 

invalid; (2) claims 1-30 of the ’764 patent are not invalid; and (3) various equitable defenses to 

infringement raised by AVC do not apply. ECF No. 180.

A. Invalidity

1. Legal Standard

Patents are presumed valid. 35 U.S.C. § 282(a). A party challenging the validity of a 

patent bears the burden of proving invalidity by clear and convincing evidence. Microsoft Corp. 

v. I4I Ltd. P’ship, 564 U.S. 91, 95 (2011). Accordingly, “a moving party seeking to have a patent 

held not invalid at summary judgment must show that the nonmoving party, who bears the burden 

of proof at trial, failed to produce clear and convincing evidence on an essential element of a 

defense upon which a reasonable jury could invalidate the patent.” Eli Lilly & Co. v. Barr Labs., 

Inc., 251 F.3d 955, 962 (Fed. Cir. 2001). In evaluating whether the nonmoving party has 

produced such evidence, the Court follows normal summary judgment practice and “views the 

evidence in the light most favorable to the nonmoving party and resolves all doubts in its favor.” 

Id. (citing Anderson, 477 U.S. at 255).

“Both anticipation under § 102 and obviousness under § 103 are two-step inquiries.” 

Medichem, S.A. v. Rolabo, S.L., 353 F.3d 928, 933 (Fed. Cir. 2003). The first step is claim

construction. Id. The second step requires a comparison of the properly construed claims to the 

prior art. Id. For a claim to be anticipated under § 102, and thus invalid, “each claim element 

must be disclosed, either expressly or inherently, in a single prior art reference, and the claimed 

arrangement or combination of those elements must also be disclosed, either expressly or 

inherently, in that same prior art reference.” Therasense, Inc. v. Becton, Dickinson & Co., 593 

F.3d 1325, 1332-33 (Fed. Cir. 2010). “Inherent anticipation requires that the missing descriptive 

material is necessarily present, not merely probably or possibly present, in the prior art.” Trintec 

Indus., Inc. v. Top-U.S.A. Corp., 295 F.3d 1292, 1295 (Fed. Cir. 2002) (internal quotation marks 

omitted). Whether prior art anticipates the accused device is a question of fact. Orion IP, LLC v. 

Hyundai Motor Am., 605 F.3d 967, 974 (Fed. Cir. 2010). 

Under 35 U.S.C. § 103, a patent claim is invalid as obvious “if the differences between the 

claimed invention and the prior art are such that the claimed invention as a whole would have been 

obvious before the effective filing date of the claimed invention to a person having ordinary skill 

in the art to which the claimed invention pertains.” “Obviousness is a legal question based on 

underlying factual determinations.” Intercontinental Great Brands LLC v. Kellogg N. Am. Co., 

869 F.3d 1336, 1343 (Fed. Cir. 2017). These factual questions include (1) “the scope and content 

of the prior art”; (2) the “differences between the prior art and the claims at issue”; (3) “the level 

of ordinary skill in the pertinent art”; and (4) any relevant secondary considerations (i.e., objective 

indicia of non-obviousness) – often referred to as the Graham factors. KSR Int’l Co. v. Teleflex, 

Inc., 550 U.S. 398, 406 (2007) (quoting Graham v. John Deere Co. of Kansas City, 383 U.S. 1, 

17-18 (1966)); see also Intercontinental Great Brands, 869 F.3d at 1343. 

The Federal Circuit has emphasized that “[o]bjective indicia of nonobviousness must be 

considered in every case where present.” Apple Inc. v. Samsung Elecs. Co., 839 F.3d 1034, 1048 

(Fed. Cir. 2016) (en banc). Also relevant is the factual question “whether the relevant skilled 

artisan had a motivation to combine pieces of prior art in the way eventually claimed in the patent 

at issue.” Intercontinental Great Brands, 869 F.3d at 1343 (citing Apple, 839 F.3d at 1047-48, 

1051). This question is distinct from “the ultimate legal determination of whether the claimed 

combination would have been obvious to the ordinary artisan – meaning that it is possible that a

reason or motivation may exist, but nonetheless the ordinary artisan would not have found the 

combination obvious.” Arctic Cat Inc. v. Bombardier Recreational Prod. Inc., 876 F.3d 1350, 

1359 (Fed. Cir. 2017).

Importantly, “a patent composed of several elements is not proved obvious merely by 

demonstrating that each of its elements was, independently, known in the prior art.” KSR, 550 

U.S. at 418. On the other hand, “when a patent simply arranges old elements with each 

performing the same function it had been known to perform and yields no more than one would 

expect from such an arrangement, the combination is obvious.” Id. at 417 (internal quotation 

marks and citation omitted). 

2. Invalidity of ’362 Patent Claims

Rather than comprehensively addressing all of the Graham factors, Asetek offers two 

specific reasons why it is entitled to summary judgment that claims 1, 3, 5-7, 9, 13-15, and 17-19

of the ’362 patent are not obvious.8 First, Asetek contends that AVC has not provided evidence 

that prior art disclosed certain elements. ECF No. 180 at 19-22. Second, Asetek argues that AVC 

has failed to provide “an adequate explanation of the motivation to combine the asserted prior art 

references and a reasonable expectation of success from doing so.” Id. at 14. 

The Federal Circuit, sitting en banc, has cautioned that “[a] determination of whether a 

patent claim is invalid as obvious under § 103 requires consideration of all four Graham factors, 

and it is error to reach a conclusion of obviousness until all those factors are considered.” Apple 

Inc., 839 F.3d at 1048. Here, for instance, the parties have offered no evidence or argument on the 

“the level of ordinary skill in the pertinent art”9or identified whether “[o]bjective indicia of 

nonobviousness” exist. Id. at 1047-48 (citation omitted). Nonetheless, as the party that does not 

 

8 Asetek also argues that it is entitled to summary judgment on AVC’s contentions that claims 1-

19 are anticipated and claims 2, 4, 8, 10-12, and 16 are obvious because AVC produced no 

admissible theories support of those contentions. ECF No. 180 at 13-14. AVC’s opposition does 

not attempt to revive any of those contentions, cf. ECF No. 194, and so the Court agrees that 

Asetek is entitled to summary judgment on those issues.

9 Although not cited by the parties, a question asked at Dr. Joshi’s deposition refers to the 

“category of people with college education in mechanical engineering.” ECF No. 180-7 at 

163:18-20. But neither the parties’ briefs nor Dr. Joshi’s expert report contain any definitive 

statement, let alone a reasoned discussion of the relevant level of skill.

bear the burden of proof at trial, Asetek may still obtain summary judgment by “negating an 

essential element of” AVC’s obviousness defense. Nissan Fire & Marine Ins. Co., 210 F.3d at

1102. The Court therefore considers whether Asetek’s arguments reveal essential elements as to 

which AVC “failed to produce clear and convincing evidence” to support a reasonable jury finding 

in its favor. Eli Lilly & Co., 251 F.3d at 962.

The Court first rejects Asetek’s argument that it is entitled to summary judgment solely 

because “AVC has not shown that the limitation ‘reservoir’ including ‘an upper chamber and a 

lower chamber’ that are separated by ‘at least a horizontal wall’ is present in any prior art 

reference.” ECF No. 180 at 21-22. “A claimed invention may be obvious even when the prior art 

does not teach each claim limitation, so long as the record contains some reason why one of skill 

in the art would modify the prior art to obtain the claimed invention.” Nike, Inc. v. Adidas AG, 

812 F.3d 1326, 1335 (Fed. Cir. 2016), overruled on other grounds by Aqua Prod., Inc. v. Matal, 

872 F.3d 1290 (Fed. Cir. 2017) (en banc). In other words, that each claim limitation be present in 

the prior art is not an “essential element” whose absence entitles Asetek to summary judgment 

without a comprehensive obviousness analysis.

Asetek’s remaining briefing on this issue can be distilled into the argument that AVC 

failed to produce evidence as to “how or why a person of ordinary skill in the art would have 

modified Schmidt (not ‘could’ have) to arrive at the inventions claimed in the ’362 patent.” ECF 

No. 205 at 11. In order to determine what modifications are necessary, however, the Court must 

first review the record as to “the scope and content of the prior art” and the “differences between 

the prior art and the claims at issue.” KSR, 550 U.S. at 406 (citation omitted).

a. Scope and Content of Prior Art

As to the scope and content of prior art, Asetek argues that Schmidt does not disclose the 

limitation found in independent claims 1, 14, and 17 of a reservoir containing (1) “an upper 

chamber and lower chamber” that are (2) “separated by at least a horizontal wall.” ECF No. 180 

at 19-20; see also ECF No. 180-13 at 18:56-60, 19:60-64, 20:33-37. 

AVC’s opposition relies almost exclusively on Dr. Joshi’s deposition testimony and 

supplemental declaration. See ECF No. 194 at 18-21. As explained above, the Court disregards

such testimony except to the extent it is “either explicitly contained in his previously-provided 

expert report or ‘a reasonable synthesis and/or elaboration of the opinions contained in [that] 

report.’” CMI USA, Inc., 2014 WL 6997670, at *1 (quoting nCube Corp. v. SeaChange Int’l, Inc., 

809 F. Supp. 2d 337, 347 (D. Del. 2011)). 

AVC first contends that item 34 of Schmidt, the atomizer plates, discloses a thermal 

exchange chamber. ECF No. 194 at 18-20. As discussed above, the Court finds that Dr. Joshi’s 

report, as elaborated on in his deposition testimony, sufficiently sets forth this theory. See ECF 

No. 180-2 at 35; ECF No. 180-4 at 29; ECF No. 180-20 at Fig. 1. Asetek does not contest on the 

merits whether item 34 discloses this limitation, ECF No. 205 at 9-10, and construing the evidence 

in the light most favorable to AVC, a reasonable jury could so find.

Second, AVC notes that item 12 of Schmidt, the pump, is surrounded by a housing (40) 

that constitutes a second thermal exchange chamber. ECF No. 194 at 20; see also, e.g., ECF No. 

180-2 at 33; ECF No. 180-20 at Fig. 2. AVC reasons that Schmidt discloses a configuration in 

which the pump and its housing are vertically separate from the atomizer plates, thereby creating 

an upper and lower chamber. ECF No. 194 at 20. The Court disagrees with Asetek that this 

theory is new. Dr. Joshi’s report states that because “[t]he pumps 12 may also be disposed outside 

of the reservoir 14 . . . . it is obvious to a person with ordinary skill in the art at time of the 

invention to relocate the pump 12 such that the housing 40 is higher than the supply manifolds 

32.” ECF No. 180-2 at 33, 53-54, 65-66. As discussed above, a jury could reasonably conclude 

that this reference to the supply manifolds included the connected atomizer plates. Thus, Dr. Joshi 

espoused that general theory, although his precise language indicates that perhaps it is better 

treated as a modification to Schmidt. Resolving this factual question in AVC’s favor, a jury could 

reasonably find that Schmidt disclosed an upper and lower chamber. 

Finally, AVC continues, Schmidt discloses how these vertically spaced chambers could be 

separated by a horizontal wall. ECF No. 194 at 20. AVC posits that the pump (12) may be 

positioned above the manifold/atomizer plate assembly, and seemingly, that the uppermost 

atomizer plate (34) provides the horizontal wall between the pump and lower atomizer plates. Id.

AVC cannot rely on this contention because it is not found in the Joshi report. Cf. ECF No. 180-2

at 33, 54, 66. Rather, the report opines that the horizontal wall element is disclosed by Yu. See id. 

at 36, 57, 69. Given AVC’s lack of admissible evidence, a reasonable jury could not find that 

Schmidt discloses this limitation.

b. Differences Between Prior Art and Claims at Issue

Besides the “separated by at least a horizontal wall” limitation, the parties do not dispute

for the purposes of this motion the various other differences between Schmidt and the ’362 patent 

identified in Dr. Joshi’s report. Dr. Joshi opines, for instance, that Schmidt does not disclose “an 

integrated liquid cooling device for a central processing unit” in claim 1, but that Yu does so. 

ECF No. 180-2 at 35. Similarly, Dr. Joshi states that neither Schmidt nor Yu disclose “the heat 

exchanging interface is removably coupled to the reservoir” limitation in claim 6, but that “Atsuo 

teaches such limitation.” Id. at 46.10 Rather than reviewing those differences in detail, the Court 

turns to the crux of the parties’ dispute: whether AVC has provided any evidence of a motivation 

to modify Schmidt with the other prior art limitations contained in Dr. Joshi’s report.

c. Motivation to Combine

In order to survive summary judgment, AVC must provide evidence that, viewed through 

the lens of summary judgment, clearly and convincingly shows “that a person of ordinary skill in 

the art would have been motivated to combine the prior art in the way claimed by the [’362] patent 

claims at issue and had a reasonable expectation of success in doing so.” Pers. Web Techs., LLC 

v. Apple, Inc., 848 F.3d 987, 991 (Fed. Cir. 2017).

The parties agree that such motivation may be found from diverse sources. See 

Plantronics, Inc. v. Aliph, Inc., 724 F.3d 1343, 1354 (Fed. Cir. 2013) (“[M]otivation to combine 

may be found explicitly or implicitly in market forces; design incentives; the ‘interrelated 

teachings of multiple patents’; ‘any need or problem known in the field of endeavor at the time of 

invention and addressed by the patent’; and the background knowledge, creativity, and common 

sense of the person of ordinary skill.” (quoting Perfect Web Techs., Inc. v. InfoUSA, Inc., 587 F.3d 

1324, 1328-29 (Fed. Cir. 2009)). Asetek contends that, even under this flexible standard, AVC’s 

 

10 Chinese Patent Release No. CN2562368Y (Yu) and PCT Publication No. WO 00/16397 

(Atsuo).

showing is defective.

First, Asetek argues that the patents concern technology of sufficient complexity that 

expert testimony of motivation is required. ECF No. 205 at 12. The Federal Circuit has explained 

that “cases involving complex technology” may require expert testimony “to establish . . . the 

existence (or lack thereof) of a motivation to combine references.” Wyers v. Master Lock Co., 616 

F.3d 1231, 1240 n.5 (Fed. Cir. 2010). But it has declined to adopt “a per se rule that expert 

testimony is required to prove infringement when the art is complex.” Centricut, LLC v. Esab 

Grp., Inc., 390 F.3d 1361, 1370 (Fed. Cir. 2004).

Here, AVC’s rebuttal that this case concerns “no more than simple mechanical 

technologies,” ECF No. 194 at 15, is “belied by the fact that [it] believed it necessary to introduce 

extensive expert testimony regarding the content of the prior art.” Alexsam, Inc. v. IDT Corp., 715 

F.3d 1336, 1348 (Fed. Cir. 2013). Moreover, the technologies here are more complex than in the 

cases cited by AVC. See Tokai Corp. v. Easton Enters., Inc., 632 F.3d 1358, 1371 (Fed. Cir. 

2011) (manual lighters); Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1365 (Fed. 

Cir. 2008) (single patent claim involving retractable tarp); Ruiz v. A.B. Chance Co., 357 F.3d 

1270, 1276 (Fed. Cir. 2004) (screw anchors and metal brackets). The technology embodied in the 

’362 patent’s system of cooling computer components is instead comparable to other cases that 

have required expert testimony regarding motivation. See, e.g., Kinetic Concepts, Inc. v. Smith & 

Nephew, Inc., 688 F.3d 1342, 1369 (Fed. Cir. 2012) (devices using “a seal capable of maintaining 

negative pressure” and “draining fluids” to treat wounds); Proveris Sci. Corp. v. Innovasystems, 

Inc., 536 F.3d 1256, 1259, 1267 (Fed. Cir. 2008) (“device used for calibrating drug delivery 

devices” comprised of “a housing,” “a spray pump actuator,” “an illumination device,” and “an 

imaging device,” each serving various mechanical functions). The Court concludes that “this 

subject matter is sufficiently complex to fall beyond the grasp of an ordinary layperson.” Proveris 

Sci. Corp., 536 F.3d at 1267.

Therefore, the Court focuses on the expert testimony properly tethered to Dr. Joshi’s

report.

11 As outlined above, Dr. Joshi’s report at most demonstrates a general industry trend, or a 

“design need,” for miniaturization. KSR, 550 U.S. at 421.

Second, Asetek contends that, given the lack of any evidence applying this miniaturization 

theory of motivation to the asserted prior art references, as a matter of law AVC cannot prevail on 

its obviousness claim. ECF No. 180 at 17-19. The Federal Circuit has held that a jury cannot 

reasonably find the motivation to support obviousness based solely on testimony that “is generic 

and bears no relation to any specific combination of prior art elements,” and that “fails to explain 

why a person of ordinary skill in the art would have combined elements from specific references 

in the way the claimed invention does.” ActiveVideo Networks, Inc. v. Verizon Commc’ns, Inc., 

694 F.3d 1312, 1328 (Fed. Cir. 2012) (affirming pre-verdict judgment as a matter of law). The 

Court must distinguish between “knowledge of a problem and motivation to solve it” and the 

requisite “motivation to combine particular references to reach the particular claimed method.” 

Innogenetics, N.V. v. Abbott Labs., 512 F.3d 1363, 1373 (Fed. Cir. 2008). 

Here, Dr. Joshi’s report contains no reference to miniaturization in his discussion of any of 

the prior art references or combinations. AVC acknowledges as much. AVC’s contention that 

“motivation to combine prior art references need not be expressly stated” in Dr. Joshi’s report 

misreads the case law. AVC cites cases holding that “suggestion or motivation need not be 

expressly stated” in the sources of motivation, such as prior art references, B.F. Goodrich Co. v. 

Aircraft Braking Sys. Corp., 72 F.3d 1577, 1582 (Fed. Cir. 1996), but those cases do not relieve a 

party claiming obviousness of its burden to articulate and support an explanation. See also DyStar 

Textilfarben GmbH & Co. Deutschland KG v. C.H. Patrick Co., 464 F.3d 1356, 1366 (Fed. Cir. 

2006) (“When not from the prior art references, the ‘evidence’ of motive will likely consist of an 

explanation of the well-known principle or problem-solving strategy to be applied.”).

 

11 Even if expert testimony were not required, it is the only source offered by AVC at summary 

judgment. See Innogenetics, N.V., 512 F.3d 1363, 1374 (Fed. Cir. 2008) (acknowledging that “an 

expert is not the only source for evidence that it would be obvious for one skilled in the art to 

combine references to reach the claimed method” but reasoning that “some kind of motivation 

must be shown from some source, so that the jury can understand why a person of ordinary skill 

would have thought of either combining two or more references or modifying one to achieve the 

patented method”).

Even assuming that some obviousness theories might be so straightforward as to require no 

more than a cursory explanation of motivation, AVC’s arguments demonstrate that this is not one 

of them. As discussed above, Dr. Joshi’s report opines that, in order to satisfy the claim limitation 

of vertically spaced chambers separated by at least a horizontal wall, it would be obvious to 

modify Schmidt to place the pump (12) outside of the reservoir (14) and above the supply 

manifold (32) and atomizer plates (34). See, e.g., ECF No. 180-2 at 33. As an initial matter,

Schmidt “provides no incentive or motivation or even commentary on why that would be 

desirable.” Hamilton Beach Brands, Inc. v. f’real Foods, LLC, 908 F.3d 1328, 1342 (Fed. Cir. 

2018). In fact, Schmidt states that “[e]ach liquid pump 12 is preferably disposed in the reservoir.” 

ECF No. 180-20 at 3:4-5 (emphasis added). More importantly, on its face, this modification 

would achieve the opposite result of the miniaturization and integration goals on which AVC now 

relies. See ECF No. 194 at 16 (“[A]ll of Schmidt, Yu, Atsuo, Bo, Brost, and Uomori prior art 

references are directed to integrate or combine one or more components of the liquid cooling 

system in order to miniaturize such system.” (emphasis added)). 

Nor does Dr. Joshi explain anywhere, even in his stricken opinions, how combining the 

prior art references would have resulted in a workable and smaller device, let alone in the specific 

invention of the ’362 patent. “[A] finding of obviousness at the time of invention requires a 

‘plausible rational[e] as to why the prior art references would have worked together.’” Broadcom 

Corp. v. Emulex Corp., 732 F.3d 1325, 1334 (Fed. Cir. 2013) (quoting Power-One, Inc. v. Artesyn 

Techs., Inc., 599 F.3d 1343, 1352 (Fed. Cir. 2010)). Ultimately, “[w]ithout any explanation as to 

how or why the references would be combined to arrive at the claimed invention,” the Court is 

“left with only hindsight bias that KSR warns against.” Metalcraft of Mayville, Inc. v. The Toro 

Co., 848 F.3d 1358, 1367 (Fed. Cir. 2017).

12

 

 

12 Though not directly raised by the parties, the Court observes that Dr. Joshi’s expert report is 

likely fatally defective for another reason as well. In InTouch Technologies, Inc. v. VGO 

Communications, Inc., the Federal Circuit reversed the jury verdict and the district court’s denial 

of judgment as a matter of law, holding that the expert’s testimony “did not even come close” to 

supporting obviousness. 751 F.3d 1327, 1348 (Fed. Cir. 2014). Like here, the expert’s “testimony 

was vague and did not articulate reasons why a person of ordinary skill in the art at the time of the 

invention would combine these references.” Id. at 1351. In addition, the InTouch court faulted the 

expert for making “no effort . . . to guard against . . . hindsight bias by appropriately considering

Because AVC failed to present evidence from which a jury could reasonably find an 

essential element of its claims, the Court grants Asetek’s motion for summary judgment as to the 

’362 patent.

3. Invalidity of ’764 Patent Claims

Asetek also moves for summary judgment on AVC’s obviousness challenge to the ’764 

patent. Asetek argues that (1) AVC likewise failed to present evidence of motivation to combine 

and (2) its prior art combinations fail as a matter of law because they would destroy the intended 

purpose of Schmidt. ECF No. 180 at 22-25.13

Regarding motivation to combine, the parties raise essentially the same arguments, and 

AVC offers the same evidence, as they did for the ’362 patent. The Court therefore reaches the 

same result.

AVC again argues that expert testimony is not always required to show motivation, ECF 

No. 194 at 22, but the Court concluded above that the patents here are sufficiently complex as to 

make such testimony necessary. See also Kinetic Concepts, 688 F.3d at 1369.

Similarly, Dr. Joshi’s report refers to a general industry trend of miniaturization, but it 

provides no “motivation to combine particular references to reach the particular claimed method.” 

Innogenetics, N.V., 512 F.3d at 1373. It likewise “fails to explain why a person of ordinary skill in 

the art would have combined elements from specific references in the way the claimed invention 

does.” ActiveVideo Networks, 694 F.3d at 1328.

Accordingly, the Court grants Asetek’s motion for summary judgment as to the ’764 

patent. The Court does not reach Asetek’s alternative argument that the asserted prior art 

combinations destroy Schmidt’s purpose.

 

all objective evidence of nonobviousness.” Id. at 1352 (emphasis added). “By failing to account 

for objective evidence of nonobviousness, [the expert’s] analysis was incomplete, and ultimately 

insufficient to establish obviousness by clear and convincing evidence.” Id. at 1352. Dr. Joshi’s 

deposition confirms that he, too, did not evaluate any secondary considerations. ECF No. 180-7 at 

34:7-12.

13 Asetek also seeks summary judgment on claims 19-30 of the ’764 patent because AVC provided 

no invalidity contentions as to those claims. ECF No. 180 at 22. AVC offers no opposition. The 

Court grants summary judgment as to those claims.

B. Equitable Defenses

In its answer to Asetek’s counterclaims, AVC asserted that “[s]ome or all of Asetek’s 

claims for damages and other relief are barred by the equitable doctrines of waiver, estoppel, 

unclean hands, acquiescence, and/or laches.” ECF No. 77 ¶ 77. Asetek seeks summary judgment 

on each of these affirmative defenses. ECF No. 180 at 25. AVC opposes the motion with respect

to laches only. ECF No. 194 at 28. The Court therefore deems AVC’s remaining defenses 

abandoned, see Ramirez v. City of Buena Park, 560 F.3d 1012, 1026 (9th Cir. 2009), and turns to 

the issue of laches.

35 U.S.C. § 286 provides that “[e]xcept as otherwise provided by law, no recovery shall be 

had for any infringement committed more than six years prior to the filing of the complaint or 

counterclaim for infringement in the action.” The Supreme Court has held, in turn, that “[l]aches 

cannot be interposed as a defense against damages where the infringement occurred within the 

period prescribed by § 286.” SCA Hygiene Prod. Aktiebolag v. First Quality Baby Prod., LLC, 

137 S. Ct. 954, 967 (2017). 

Here, the ’362 patent and ’764 patent both issued in August 2012. See ECF No. 180-13 at 

2; ECF No. 180-14 at 2. Asetek argues that, because it filed its counterclaims of infringement in 

July 2017, see ECF No. 73 ¶¶ 63-73, its infringement claims are necessarily within § 286’s sixyear period and thus not barred by laches. ECF No. 180 at 29. AVC responds that there is 

nonetheless a disputed factual issue whether Asetek’s allegations of infringement cover a period 

beginning in 2008. ECF No. 194 at 28-29. But Asetek has amended its damages start date to 

January 2, 2013. See ECF No. 203 at 23. Therefore, facts surrounding earlier allegations of 

infringement for which Asetek does not seek damages are immaterial. See Exmark Mfg. Co. Inc. 

v. Briggs & Stratton Power Prod. Grp., LLC, 879 F.3d 1332, 1353 (Fed. Cir. 2018) (“Because 

Exmark only seeks damages for the six-year period prior to filing its complaint against Briggs, we 

agree with the district court that Briggs cannot assert laches as a defense.”).

Accordingly, the Court grants Asetek summary judgment on laches and AVC’s other 

abandoned equitable defenses.

V. AVC’S MOTION FOR SUMMARY JUDGMENT

AVC seeks summary judgment on various theories of infringement advanced by Asetek, as 

well as other questions regarding the scope of its liability. ECF No. 186.

A. Infringement

Asetek has raised counterclaims for direct infringement, 35 U.S.C. § 271(a), indirect 

infringement, id. § 271(b), and contributory infringement, id. § 271(c). See ECF No. 73 ¶¶ 64-66, 

70-71. Further, Asetek seeks enhanced damages for willful infringement pursuant to 35 U.S.C. 

§ 284. See ECF No. 73 ¶¶ 67, 72.

In its motion, AVC requests summary judgment as to its liability for indirect and 

contributory infringement, as well as the availability of enhanced damages under § 284. 

1. Legal Standard

Summary judgment of non-infringement requires “a two-part inquiry: first, a court 

construes the scope and meaning of the asserted patent claims, and then compares the construed 

claims to the accused product or process.” Medgraph, Inc. v. Medtronic, Inc., 843 F.3d 942, 949 

(Fed. Cir. 2016). The Federal Circuit has held that “[i]nfringement is a question of fact.” Id. “To 

support a summary judgment of non-infringement it must be shown that, on the correct claim 

construction, no reasonable jury could have found infringement on the undisputed facts or when 

all reasonable factual inferences are drawn in favor of the patentee.” Netword, LLC v. Centraal 

Corp., 242 F.3d 1347, 1353 (Fed. Cir. 2001). Because the patentee bears the burden of proving 

infringement, an accused infringer may carry its initial burden in moving for summary judgment 

by “stating that the patentee ha[s] no evidence of infringement and pointing to the specific ways in 

which accused systems did not meet the claim limitations.” Exigent Tech., Inc. v. Atrana Sols., 

Inc., 442 F.3d 1301, 1308-09 (Fed. Cir. 2006).

2. Patent Local Rules

As a threshold matter, the Court addresses AVC’s contentions that deficiencies in Asetek’s 

infringement contentions require summary judgment in AVC’s favor. ECF No. 186 at 12 (willful 

infringement), 18 (induced infringement), 21 (contributory infringement).

AVC cites no authority providing that the insufficiencies of contentions under the Patent

United States District Court

Northern District of California

Local Rules are a basis for granting summary judgment. To the contrary, courts in this district 

have explained that where parties believe that the substance of infringement contentions are 

defective, the proper course is to bring a dispositive motion based on the appropriate record. See 

Synopsys, Inc. v. ATopTech, Inc., No. 13CV02965MMCDMR, 2015 WL 5210669, at *6 (N.D. 

Cal. Sept. 7, 2015) (“To the extent ATopTech believes that basis [for the willful infringement 

contentions] is insufficient to state a claim, the proper course of action is to file a motion before 

the presiding judge challenging the sufficiency of the pleadings, not the present motion to strike 

the ICs.” (emphasis added)); GN Resound A/S v. Callpod, Inc., No. C 11-04673 SBA, 2013 WL 

1190651, at *7 (N.D. Cal. Mar. 21, 2013) (“Defendant has not cited any authority holding that a 

disclosure under Rule 3-1(h) requires a Plaintiff to disclose facts sufficient to state a cognizable 

claim for willful infringement. . . . To the extent Defendant believes the operative complaint fails 

to state a claim for willful infringement, Defendant may file the appropriate motion under the 

Federal Rules of Civil Procedure.”). AVC does not argue that the asserted defects preclude 

consideration of any specific piece of evidence in the summary judgment record before the Court. 

Accordingly, AVC’s arguments regarding the sufficiency of Asetek’s infringement contentions are 

irrelevant. 

3. Direct Infringement

Direct infringement occurs where one “without authority makes, uses, offers to sell, or 

sells any patented invention, within the United States or imports into the United States any 

patented invention during the term of the patent.” 35 U.S.C. § 271(a). Because “[d]irect 

infringement is a strict-liability offense,” the “defendant’s mental state is irrelevant” to a § 271(a) 

claim. Commil USA, LLC v. Cisco Sys., Inc., 135 S. Ct. 1920, 1926 (2015).

AVC does not seek summary judgment on direct infringement, i.e., that its products do not 

directly infringe the patents-in-suit. Rather, it argues that its non-infringement defenses are 

sufficiently strong that it is entitled to summary judgment on its liability for willful infringement. 

See ECF No. 186 at 12-14. The Court therefore addresses AVC’s arguments further below.

4. Induced Infringement

a. Legal Standard

In addition to those who directly infringe, “[w]hoever actively induces infringement of a 

patent shall be liable as an infringer.” 35 U.S.C § 271(b). In other words, “[i]nduced 

infringement under § 271(b) requires knowledge that the induced acts constitute patent 

infringement.” Glob.-Tech Appliances, Inc. v. SEB S.A., 563 U.S. 754, 766 (2011). This requires

not only knowledge of the existence of the patent that is infringed, but that “the defendant knew 

the acts were infringing.” Commil USA, 135 S. Ct. at 1928. Therefore, a party asserting induced 

infringement must “prove that: (1) a third party directly infringed the asserted claims of the 

[relevant] patents; (2) [the defendant] induced those infringing acts; and (3) [the defendant] knew 

the acts it induced constituted infringement.” Power Integrations, Inc. v. Fairchild Semiconductor 

Int’l, Inc. (Power Integrations II), 843 F.3d 1315, 1332 (Fed. Cir. 2016).

To satisfy the knowledge requirement, either actual knowledge or willful blindness is 

required. Glob.-Tech Appliances, 563 U.S. at 768. “Willful blindness is a high standard, 

requiring that the alleged inducer (1) subjectively believe that there is a high probability that a fact 

exists and (2) take deliberate actions to avoid learning of that fact.” Info-Hold, Inc. v. Muzak LLC, 

783 F.3d 1365, 1373 (Fed. Cir. 2015) (citing Glob.-Tech Appliances, 563 U.S. at 769).

b. Discussion

First, AVC does not argue that there were no underlying acts of direct infringement by 

third parties. Given that AVC does not meaningfully dispute that the infringement analysis in

Asetek’s expert report raises triable issues as to direct infringement, see ECF No. 203-18, the 

Court concludes that a reasonable jury could find this requirement satisfied.

Second, a jury could reasonably conclude that AVC “took an affirmative act to encourage 

infringement.” Info-Hold, Inc., 783 F.3d at 1372 (citation omitted). Asetek argues that AVC took 

the affirmative step of “manufacturing and selling/shipping the 1.5, 2.0, K7127N and K9 products 

to the United States,” thereby supporting induced infringement as to claims 14 and 15 of the ’362 

patent and claims 1-19, 21-23, 25-27, 29, and 30 of the ’764 patent. ECF No. 203 at 17. In 

support, Asetek has produced unrebutted evidence that AVC sold and shipped its products to

customers within the United States. See ECF No. 203-7 at 3-5. This far exceeds the showing in 

Power Integrations II, where the accused infringer argued that it sold its products “overseas into a 

worldwide distribution system with no knowledge of where its chips will ultimately end up.” 843 

F.3d at 1333. Nevertheless, the Federal Circuit held there that a jury could reasonably find an 

affirmative step based on evidence that the infringer designed and marketed its products for the 

United States. Id. at 1333-34. Here, where it is undisputed that AVC knowingly sold and shipped 

products directly to the United States, a jury could even more readily find the requisite affirmative 

step. AVC entirely bypasses this element of Asetek’s argument, focusing instead on whether the 

instruction manuals constitute an affirmative step inducing infringement of the ’362 patent’s 

method claims. 

Turning to those claims, Asetek argues that there is evidence that “AVC has specifically 

designed, promoted, and sold the product[s] for [the] sole and very purpose” of practicing the 

methods of claims 17-19. ECF No. 203 at 17-18. Further, Asetek contends, there is a disputed 

issue of fact whether AVC prepared or provided input into the user manuals. Id. The Court need 

not reach the issue of AVC’s role in the manuals because Asetek’s first argument is sufficient for 

it to survive summary judgment on this point. A jury can reasonably find “an affirmative act” 

encouraging infringement from the infringer “incorporating components whose sole purpose is to 

cause the [products] to operate in a manner that infringes the [asserted] patents under normal 

circumstances.” Ricoh Co. v. Quanta Computer Inc., 550 F.3d 1325, 1343 (Fed. Cir. 2008). Here, 

Asetek’s expert report indicates that the accused products “necessarily infringe the relevant 

claims,” Power Integrations, 843 F.3d at 1333, because their “only function” is “to perform 

[Asetek’s] patented methods,” Ricoh, 550 F.3d at 1343; ECF No. 203-18 ¶¶ 449-450. As 

explained in greater detail when discussing contributory infringement, there are triable issues of 

fact whether that is the case. Accordingly, the Court holds that a jury could reasonably find that 

AVC took affirmative steps to induce direct infringement. 

Finally, the Court finds sufficient evidence from which a reasonable jury could conclude

that AVC acted with the requisite knowledge. As an initial matter, AVC does not dispute that it 

“knew of the patent[s],” Commil USA, 135 S. Ct. at 1926, soon after they issued in August 2012.

See ECF No. 203-5 at 10. Moreover, AVC has known since December 2006 of the applications

that ultimately issued as the ’362 and ’764 patents. Id. 

Further, a jury could reasonably find that AVC actually knew of the infringing nature of its 

conduct. AVC clearly knew of Asetek’s infringement allegations as to some of its products by the 

time it filed its action for declaratory relief on September 30, 2014, see ECF No. 1, and a

reasonable jury could further conclude that Asetek adequately informed AVC of the alleged 

infringement through its August 2, 2014 letter, see ECF No. 203-12 at 2. 

Asetek additionally presents deposition testimony regarding a 2014 meeting in which AVC 

purportedly attempted to obtain a license for the two patents-in-suit. See ECF No. 202-12 at 

240:20-241:10. A jury could credit this testimony of a failed attempt to license the patents, which 

the Federal Circuit has recognized as “evidence supporting proof of intent for inducement.” Fuji 

Photo Film Co. v. Jazz Photo Corp., 394 F.3d 1368, 1378 (Fed. Cir. 2005); Mentor H/S, Inc. v. 

Med. Device All., Inc., 244 F.3d 1365, 1379 (Fed. Cir. 2001). 

Asetek also points to contemporaneous litigation before this Court concerning 

infringement of the ’362 and ’764 patents. See generally Asetek Danmark A/S v. CMI USA Inc., 

852 F.3d 1352 (Fed. Cir. 2017). In that case, a jury rendered a December 2014 verdict that the 

accused products – the Cooler Master Products – infringed the two patents, and this Court denied 

CMI’s post-trial motions on infringement in September 2015. Id. at 1357-58. Asetek submits 

evidence that AVC closely followed the proceedings, ECF No. 203-2 ¶ 24, and that it considered 

its products structurally similar to the Cooler Master Products, ECF No. 180-18 at 14-16. A jury 

could reasonably treat this evidence as further confirming to AVC that its conduct would lead to 

infringement.

AVC does not dispute this evidence, but rather relies on its “reasonable non-infringement 

and invalidity defenses.” ECF No. 186 at 17. AVC’s asserted belief that the patents were invalid

is irrelevant to this inquiry. See Commil USA, 135 S. Ct. at 1928. AVC’s asserted good faith noninfringement belief, on the other hand, “is relevant evidence that tends to show that an accused 

inducer lacked the intent required to be held liable for induced infringement.” Commil USA, LLC 

v. Cisco Sys., Inc., 720 F.3d 1361, 1367-68 (Fed. Cir. 2013), vacated in part on other grounds,

135 S. Ct. 1920 (2015); see also Warsaw Orthopedic, Inc. v. NuVasive, Inc., 824 F.3d 1344, 1351 

& n.2 (Fed. Cir. 2016). But relevance is not enough for a grant of summary judgment: even if the 

Court were to conclude that AVC’s non-infringement defenses were “strong,” that would at most 

“create a factual question as to [AVC’s] own subjective beliefs,” and would not defeat Asetek’s 

claims. Unwired Planet, LLC v. Apple Inc., 829 F.3d 1353, 1363 (Fed. Cir. 2016).14 

Ultimately, Asetek has adduced sufficient evidence for the jury to conclude as a factual 

matter that AVC actually knew of the infringing results of its actions.15 

5. Contributory Infringement

a. Legal Standard

35 U.S.C. § 271(c) “incorporates the core notion that one who sells a component especially 

designed for use in a patented invention may be liable as a contributory infringer, provided that the 

component is not a staple article of commerce suitable for substantial non-infringing use.” Ricoh, 

550 F.3d at 1337.16 To succeed on a contributory infringement claim, the patentee must establish: 

“(1) that there is direct infringement, (2) that the accused infringer had knowledge of the patent, 

 

14 Here, perhaps because AVC has not moved for summary judgment on the underlying question 

of non-infringement, the parties have not directly argued the issue in any depth. See ECF No. 186 

at 17 (stating, without further explanation, that “AVC believes that the Accused Products do not 

infringe the ’362 and ’764 patents”). Accordingly, consideration of the reasonableness of AVC’s 

position is largely premature and the Court reaches no firm conclusions about the merits of AVC’s 

defenses. The Court does, however, reject Asetek’s reliance on AVC’s “failure to procure opinion 

of counsel on non-infringement.” ECF No. 203 at 16 (citing Broadcom Corp., 543 F.3d at 699). 

This argument is now barred by 35 U.S.C. § 298, which provides, in relevant part, that “[t]he 

failure of an infringer to obtain the advice of counsel with respect to any allegedly infringed patent 

. . . may not be used to prove that the accused infringer willfully infringed the patent or that the 

infringer intended to induce infringement of the patent.” See also Carson Optical Inc. v. eBay 

Inc., 202 F. Supp. 3d 247, 261 (E.D.N.Y. 2016). 

15 The Court therefore does not reach the issue whether AVC was willfully blind.

16 35 U.S.C. § 271(c) provides in full:

Whoever offers to sell or sells within the United States or imports into 

the United States a component of a patented machine, manufacture, 

combination or composition, or a material or apparatus for use in 

practicing a patented process, constituting a material part of the 

invention, knowing the same to be especially made or especially 

adapted for use in an infringement of such patent, and not a staple 

article or commodity of commerce suitable for substantial noninfringing use, shall be liable as a contributory infringer.

(3) that the component has no substantial non-infringing uses, and (4) that the component is a 

material part of the invention.” Fujitsu Ltd. v. Netgear Inc., 620 F.3d 1321, 1326 (Fed. Cir. 2010). 

As with induced infringement, “contributory infringement requires knowledge of the 

patent in suit and knowledge of patent infringement.” Commil USA, 135 S. Ct. at 1926. This 

knowledge requirement demands “only proof of a defendant’s knowledge, not intent, that his 

activity cause infringement.” Lifetime Indus., Inc. v. Trim-Lok, Inc., 869 F.3d 1372, 1381 (Fed. 

Cir. 2017) (quoting Hewlett-Packard Co. v. Bausch & Lomb Inc., 909 F.2d 1464, 1469 (Fed. Cir. 

1990) (emphasis in original)).

A substantial non-infringing use is one that is “not unusual, far-fetched, illusory, 

impractical, occasional, aberrant, or experimental.” Vita-Mix Corp. v. Basic Holding, Inc., 581 

F.3d 1317, 1327 (Fed. Cir. 2009). In making this determination, the factfinder may “consider not 

only the use’s frequency, but also the use’s practicality, the invention’s intended purpose, and the 

intended market.” i4i Ltd. P’ship v. Microsoft Corp., 598 F.3d 831, 851 (Fed. Cir. 2010), aff’d, 

564 U.S. 91 (2011). Once the plaintiff makes a prima facie showing that defendant’s product is 

not suitable for substantial non-infringing use, the burden of demonstrating a non-infringing use 

shifts to the defendant. Golden Blount, Inc. v. Robert H. Peterson Co. (Golden Blount II), 438 

F.3d 1354, 1363 (Fed. Cir. 2006).

b. Discussion

AVC contests only the knowledge and substantial non-infringing use elements of Asetek’s 

contributory infringement claim.17

First, AVC argues that it lacks the requisite knowledge of infringement because its 

products were not incorporated into the Liqmax 120 product referenced in Asetek’s April 30, 2014 

letter. ECF No. 186 at 20. But as discussed above, Asetek has produced sufficient evidence for a 

jury to reasonably conclude that AVC had knowledge of infringement by August 2, 2014. See

ECF No. 203-12 at 2. Because Asetek does not argue that its earlier letter regarding the Liqmax 

 

17 As noted above, AVC does not dispute that there is sufficient evidence from which a jury could 

reasonably find direct infringement by AVC’s third-party customers or end users. Nor does AVC 

argue that the component at issue is not a material part of the invention.

120 product is the basis for AVC’s knowledge, the Court need not resolve that question. 

Second, AVC argues that Asetek has failed to show that the accused products have no 

substantial non-infringing uses. ECF No. 186 at 20-21. 

In order to make its prima facie showing, Asetek points to its expert infringement report, in 

which Dr. Tilton opines that the accused products “are especially made and adapted for use in an 

infringing manner,” and that AVC “designed, promoted, and sold [them] for that sole and very 

purpose.” ECF No. 203-18 ¶¶ 449-450. Dr. Tilton further opines that the user manuals for the 

2.0, K7127N, and K9 products instruct end users to install and use those products in a manner that 

necessarily infringes the method claims of the ’362 patent. Id. ¶¶ 448-450; see also ECF Nos. 

203-19, 203-20, 203-21. “Evidence that the instruction sheets taught only the infringing 

configuration,” construed in the non-movant’s favor, is sufficient to shift the burden to AVC “to 

introduce some evidence that end-users actually [used its products] in a non-infringing way.” 

Golden Blount II, 438 F.3d at 1363-64; see also Mentor H/S, 244 F.3d at 1379 (explaining that, 

where manual stated that accused product was “specifically manufactured” for infringing purpose 

of ultrasonic liposuction, jury need not credit “assertions that [the product] had other potential uses 

because the record does not indicate any actual uses of the device other than ultrasonic 

liposuction”). 

Noting that claims 17-19 of the ’362 patent teach a method for cooling “an electronic 

component positioned on a motherboard,” ECF No. 180-13 at 20:29-30, AVC cites Dr. Tilton’s 

report’s statement that one of the advantages of the ’362 patent’s design is that it permits “factoryfloor swap outs of cold plates tailored to different CPUs’ (or GPU’s) characteristics.” ECF No. 

203-18 ¶ 40. AVC argues that its products have a substantial non-infringing use because GPUs

need not be positioned on a motherboard. ECF No. 186 at 21. Further, AVC stresses, Dr. 

Clarksean opined in his declaration that two Asetek liquid cooling products could be configured to 

cool a GPU that is not positioned on a motherboard, thus demonstrating that this use is possible. 

ECF No. 186-2 ¶¶ 8-11. Asetek urges the Court to strike these purportedly new expert opinions, 

but the Court need not decide that issue. 

Even considering Dr. Clarksean’s declaration, AVC cannot establish that there are no

material facts in dispute as to whether its asserted non-infringing use is substantial. Where 

instruction manuals show an infringing use only, a factfinder need not credit hypothetical other 

uses unaccompanied by evidence of actual use. See Golden Blount II, 438 F.3d at 1363-64 

(substantial evidence supported district court’s contributory infringement finding where infringer 

“introduced no evidence that anyone actually made or used the assembly in a manner contrary to 

the instructions so as to form a non-infringing assembly”); Mentor H/S, 244 F.3d at 1379. At a 

minimum, factual issues as to whether this use is “substantial” preclude summary judgment.

The Court therefore denies AVC’s motion for summary judgment on contributory 

infringement.

6. Willful Infringement (Enhanced Damages)

a. Legal Standard

35 U.S.C. § 284 provides that “the court may increase the damages up to three times the 

amount found or assessed.” The Supreme Court has observed that “[t]hat language contains no 

explicit limit or condition, and we have emphasized that the ‘word “may” clearly connotes 

discretion.’” Halo Elecs., Inc. v. Pulse Elecs., Inc., 136 S. Ct. 1923, 1931 (2016) (quoting Martin 

v. Franklin Capital Corp., 546 U.S. 132, 136 (2005)). Nonetheless, the Halo Court instructed that 

enhanced damages under § 284 “are not to be meted out in a typical infringement case,” but rather 

“should generally be reserved for egregious cases typified by willful misconduct.” Id. at 1932, 

1934.

Prior to Halo, the Federal Circuit had developed a two-part test for “willful” infringement 

warranting enhanced damages, which required the patentee to show by clear and convincing 

evidence that (1) “the infringer acted despite an objectively high likelihood that its actions 

constituted infringement of a valid patent,” and (2) that the risk “was either known or so obvious 

that it should have been known to the accused infringer.” In re Seagate Tech., LLC, 497 F.3d 

1360, 1371 (Fed. Cir. 2007) (en banc), abrogated by Halo, 136 S. Ct. 1923. The Halo Court 

rejected the Federal Circuit’s test as “unduly rigid.” 136 S. Ct. at 1932 (citation omitted). Among 

other things, the Supreme Court held that “[t]he subjective willfulness of a patent infringer, 

intentional or knowing, may warrant enhanced damages, without regard to whether his

infringement was objectively reckless.” Id. at 1933. The Court further held that a preponderance 

of the evidence standard – rather than a clear and convincing one – must govern the enhanced 

damages inquiry. Id. at 1934. 

Subsequent Federal Circuit decisions have emphasized that “[w]e do not interpret Halo as 

changing the established law that the factual components of the willfulness question should be 

resolved by the jury.” WBIP, LLC v. Kohler Co., 829 F.3d 1317, 1341 (Fed. Cir. 2016). Indeed, 

“under Halo, the district court no longer determines as a threshold matter whether the accused 

infringer’s defenses are objectively reasonable. Rather, the entire willfulness determination is to 

be decided by the jury.” Exmark Mfg. Co., 879 F.3d at 1353. The Federal Circuit has cautioned, 

however, that “an award of enhanced damages does not necessarily flow from a willfulness 

finding.” Presidio Components, Inc. v. Am. Tech. Ceramics Corp., 875 F.3d 1369, 1382 (Fed. Cir. 

2017). Instead, “[d]iscretion remains with the court to determine whether the conduct is 

sufficiently egregious to warrant enhanced damages,” in light of the “overall circumstances of the 

case.” Id.

b. Discussion

AVC argues that Asetek has failed to produce evidence from which a jury could 

reasonably find willfulness. ECF No. 186 at 13-14. The Court disagrees. 

As an initial matter, AVC’s heavy reliance on the reasonableness of the obviousness and 

non-infringement defenses presented in this litigation is misplaced, as the reasonableness of its 

non-infringement position does not preclude a finding of willfulness. See Halo, 876 F.3d at 1371. 

Further, because “an infringer’s subjective bad faith alone may support an award of 

enhanced damages,” culpability is measured “by assessing the infringer’s knowledge at the time of 

the challenged conduct.” WBIP, 829 F.3d at 1340. A jury can reasonably find willfulness where 

the accused infringer “knew about the patents before they issued, conducted only a cursory 

analysis of the patents, . . . and unsuccessfully tried to buy the asserted patents through a third 

party.” Arctic Cat, 876 F.3d at 1371. 

Here, the evidence construed in the light most favorable to Asetek could reasonably lead a 

jury to a similar conclusion. AVC knew about the patents soon after they issued and was aware of

the initial applications beginning in December 2006. See ECF No. 203-5 at 10. Moreover, 

Asetek’s evidence that AVC “unsuccessfully tried to [license] the asserted patents” further 

supports a finding of willfulness. Arctic Cat, 876 F.3d at 1371; see also ECF No. 203-14 at 

240:20-241:10. Though the parties present dueling narratives regarding their development of prior 

liquid cooling products and business dealings, see ECF No. 203 at 11-12; ECF No. 207 at 6-8, 

these are factual questions. See WBIP, 829 F.3d at 1341. Similarly, the parties propose opposing 

inferences to be drawn from the re-examination proceedings before the U.S. Patent and Trademark 

Office. See ECF No. 203 at 13-14; ECF No. 207 at 10-11. To the extent they are relevant, these 

disputes weigh in Asetek’s favor at this stage. Finally, the jury need not give weight to AVC’s 

declaration testimony of its contemporaneous belief of non-infringement. See Polara Eng’g Inc.

v. Campbell Co., 894 F.3d 1339, 1354 (Fed. Cir. 2018) (concluding that, in finding willful 

infringement, “the jury was entitled not to credit [the infringer’s president’s] testimony” that he 

“received ‘a clean bill of health’ from [a third-party analysis] and ‘got the go’ from his own ‘IP 

attorneys’”); ECF No. 207-1 ¶ 6.18 

In light of these material factual disputes regarding willfulness – in addition to AVC’s 

liability for direct, induced, and contributory infringement – the Court declines to decide as a 

matter of law “whether the case is sufficiently egregious to warrant enhancing damages.” WBIP, 

829 F.3d at 1342. Accordingly, the Court denies AVC’s motion for summary judgment on its 

liability for enhanced damages under 35 U.S.C. § 284.

B. Extraterritorial Sales

Next, AVC seeks summary judgment on the question whether it is “liable to Asetek for 

damages regarding AVC’s sales to customers not located in the [United States].” ECF No. 186 at 

11. 

/ / /

 

18 It is unclear the extent to which AVC’s willfulness argument relies on its filing of a declaratory 

judgment action. See ECF No. 186 at 14. The Court notes, however, that the Federal Circuit has 

clarified that when a party files an action seeking a declaration of non-infringement, for purposes 

of willfulness, “[t]he relevant date for determining which conduct is pre-suit is the date of the 

patentee’s affirmative allegation of infringement, in this case the date of [Asetek’s] counterclaim.” 

Mentor Graphics Corp. v. EVE-USA, Inc., 851 F.3d 1275, 1295 (Fed. Cir. 2017).

United States District Court

Northern District of California

1. Legal Standard

In general, “no infringement occurs when a patented product is made and sold in another 

country.” Microsoft Corp. v. AT & T Corp., 550 U.S. 437, 441 (2007). But whether a sale occurs 

in another country rather than the United States can raise factual questions. As the Federal Circuit 

has observed, “[t]he standards for determining where a sale may be said to occur do not pinpoint a 

single, universally applicable fact that determines the answer, and it is not even settled whether a 

sale can have more than one location.” Carnegie Mellon Univ. v. Marvell Tech. Grp., Ltd., 807 

F.3d 1283, 1308 (Fed. Cir. 2015). While the Carnegie Mellon court posited that “[p]laces of 

seeming relevance include a place of inking the legal commitment to buy and sell and a place of 

delivery, and perhaps also a place where other substantial activities of the sales transactions 

occurred,” id. (internal quotation marks and citations omitted), it declined to “settle on a legal 

definition or even to say whether any sale has a unique location,” id. Subsequent cases confirm 

the fact-intensive nature of this inquiry. For instance, in Halo, the Federal Circuit held on remand 

that “when substantial activities of a sales transaction, including the final formation of a contract 

for sale encompassing all essential terms as well as the delivery and performance under that sales 

contract, occur entirely outside the United States, pricing and contracting negotiations in the 

United States alone do not constitute or transform those extraterritorial activities into a sale within 

the United States for purposes of § 271(a).” Halo Elecs., Inc. v. Pulse Elecs., Inc., 831 F.3d 1369, 

1378 (Fed. Cir. 2016).

2. Discussion

Here, Asetek has presented sufficient evidence to at least raise a disputed issue of fact as to 

the location of AVC’s sales to the identified customers that form the basis for Asetek’s damages 

calculations. AVC’s documents characterize IBuyPower sales as U.S. sales. See ECF No. 203-7 

at 4-5. Similarly, those documents list AVC’s transactions with Riotoro as U.S. sales. See ECF 

No. 202-3 at 2-4. Finally, AVC’s Rule 30(b)(6) witness testified that AVC’s sales to ENERMAX 

Taipei were shipped directly to the United States. ECF No. 202-5 at 149:5-20.19 

 

19 In particular, AVC’s witness testified: “Based on what I know, ENERMAX requested us to 

ship the products to a location in the U.S. Yes.” ECF No. 202-5 at 149:18-20. AVC

In reply, AVC does not dispute any of the assertions regarding these particular customers, 

but rather appears to seek summary judgment on sales to unidentified customers for which AVC’s 

sales were “outside of the U.S.” ECF No. 207 at 5. The Court cannot engage in this exercise. 

Without actual sales to consider, the Court has no factual context with which to evaluate where the 

sales occurred, and therefore, no basis to grant summary judgment in AVC’s favor. Cf. Halo, 831 

F.3d at 1378; Carnegie Mellon, 807 F.3d at 1308-09. 

Moreover, extraterritorial limits on liability do not apply in the same manner to induced 

infringement. “[P]urely extraterritorial conduct cannot constitute direct infringement of a U.S. 

patent, as § 271(a) includes express language limiting its scope to domestic acts.’” Merial Ltd. v. 

Cipla Ltd., 681 F.3d 1283, 1302 (Fed. Cir. 2012) (citing 35 U.S.C. § 271(a)).

20 On the other hand, 

the Federal Circuit has explained, because § 271(b) “contains no such territorial proscription,” 

liability can for induced infringement can arise “where a foreign party, with the requisite 

knowledge and intent, employs extraterritorial means to actively induce acts of direct infringement 

that occur within the United States.” Id.; see also Enplas Display Device Corp. v. Seoul 

Semiconductor Co., Ltd., 909 F.3d 398, 408 (Fed. Cir. 2018) (same). Because the Court has 

denied AVC’s motion for summary judgment on induced infringement, AVC remains potentially 

liable for extraterritorial sales that induced direct infringement within the United States.

Accordingly, the Court denies AVC’s motion for summary judgment on extraterritorial 

sales.

C. Marking Analysis

AVC further asserts that it is not liable for goods sold prior to May 15, 2017 (the date 

Asetek served its infringement contentions) because Asetek failed to comply with the marking 

 

unsuccessfully sought to retroactively change that response to “a location in Hong Kong” as part 

of a series of 21 deposition errata, which were all stricken by Magistrate Judge Illman as 

impermissibly contradicting the substance of the testimony. See ECF No. 213.

20 That subsection provides: “[W]hoever without authority makes, uses, offers to sell, or sells any 

patented invention, within the United States, or imports into the United States any patented

requirements of 35 U.S.C. § 287(a). ECF No. 186 at 7, 21.

1. Legal Standard

“Pursuant to 35 U.S.C. § 287(a), a patentee who makes or sells a patented article must 

mark his articles or notify infringers of his patent in order to recover damages.” Arctic Cat, 876 

F.3d at 1365.21 Otherwise, the patentee must give the infringer “actual notice,” which requires an 

“affirmative communication [to the alleged infringer] of a specific charge of infringement by a 

specific accused product or device.” Gart v. Logitech, Inc., 254 F.3d 1334, 1345 (Fed. Cir. 2001) 

(quoting Amsted Indus. Inc. v. Buckeye Steel Castings Co., 24 F.3d 178, 187 (Fed. Cir. 1994)).

Moreover, “[a] patentee’s licensees must also comply with § 287, because the statute 

extends to ‘persons making or selling any patented article for or under [the patentee].’” Arctic 

Cat, 876 F.3d at 1366 (second alteration in original) (quoting 35 U.S.C. § 287(a)). This 

requirement extends to both express and implied licensees. Amsted Indus., 24 F.3d at 185. Given 

that “it may be difficult for a patentee to ensure his licensees’ compliance with the marking 

provisions . . . courts may consider ‘whether the patentee made reasonable efforts to ensure 

compliance with the marking requirements’” in those instances. Arctic Cat, 876 F.3d at 1366 

(quoting Maxwell v. J. Baker, Inc., 86 F.3d 1098, 1111 (Fed. Cir. 1996)). 

Compliance with § 287(a)’s marking requirements is a question of fact. Funai Elec. Co. v. 

Daewoo Elecs. Corp., 616 F.3d 1357, 1373 (Fed. Cir. 2010). “The patentee bears the burden of 

proving compliance by a preponderance of evidence.” Nike, Inc. v. Wal-Mart Stores, Inc., 138 

F.3d 1437, 1446 (Fed. Cir. 1998).

2. Discussion

AVC first argues that Asetek’s evidence of marking is insufficient for a reasonable jury to 

infer that Asetek marked “substantially all” of its products. Nike, 138 F.3d at 1446.

 

21 A patentee may satisfy the marking requirement “either by fixing thereon the word ‘patent’ or 

the abbreviation ‘pat.’, together with the number of the patent, or by fixing thereon the word 

‘patent’ or the abbreviation ‘pat.’ together with an address of a posting on the Internet, accessible 

to the public without charge for accessing the address, that associates the patented article with the 

number of the patent, or when, from the character of the article, this can not be done, by fixing to 

it, or to the package wherein one or more of them is contained, a label containing a like notice.” 

35 U.S.C. § 287(a).

In its opposition, Asetek cites engineering and assembly drawings showing the placement 

on some of its products of barcode labels that include the phrase “pat. www.ip-mark.com.” ECF 

No. 203 at 24-5 (citing ECF Nos. 186-8, 187-5, 202-8). There is also documentary evidence that 

this website has operated since at least January 2013. See ECF No. 186-9 at 2. Finally, Asetek 

points to its CEO’s deposition testimony that Asetek consistently used this virtual marking on its 

products. ECF No. 203-14 at 74:7-13, 79:6-80:12.

Under Federal Circuit precedent, this is “sufficient evidence to support [a reasonable] 

jury’s conclusion that [Asetek] consistently marked substantially all of its [products].” SEB S.A. v. 

Montgomery Ward & Co., 594 F.3d 1360, 1378 (Fed. Cir. 2010). In SEB, the patentee’s CEO 

testified at trial “that ‘to the best of [his] knowledge’ SEB’s deep fryers were ‘always’ marked and 

that SEB had a policy of marking its products.” Id. (alteration in original). In addition, SEB 

presented “one of its deep fryers with an unknown manufacturing date that had a sticker that listed 

the [patent-in-suit].” Id. Despite the CEO’s admission on cross-examination that a batch of 

products did not contain the patent marking and his earlier deposition testimony that he lacked 

knowledge of the company’s marking practices, the Federal Circuit found sufficient evidence to 

support the verdict. Id. Similarly, in Sentry Protection Products, Inc. v. Eagle Manufacturing 

Co., the Federal Circuit concluded that the patentee had met its burden to defeat summary 

judgment based on “an affidavit stating that its products were marked, together with documents 

showing sales in that period.” 400 F.3d 910, 918 (Fed. Cir. 2005).

AVC correctly states that “to satisfy the constructive notice provision, a patentee must 

mark, with the relevant patent number, substantially all of the patented products in a substantially 

consistent and continuous manner.” ECF No. 186 at 24 (citing Nike,138 F.3d at 1446). But AVC 

then goes on to suggest that because Asetek produced “at least 50 different models” and sold over 

“5 million liquid cooling products” overall, it must now present evidence that it marked each of 

those products, and not just the five units it provided in discovery. ECF No. 186 at 24 (citing ECF 

No. 187-14 at 65:1-8); see also ECF No. 208-5 at 17 (citing ECF No. 208-9 at 92:9-24). There is 

no authority for such a stringent burden of proof, and AVC’s position is directly contradicted by

Second, AVC argues that Asetek failed to make “reasonable efforts to ensure compliance 

with the marking requirements” by its licensees. Maxwell, 86 F.3d at 1111. AVC points to two 

agreements between Asetek and Corsair Components, Inc. and Corsair Memory, Inc. (collectively, 

“Corsair”): (1) a licensing agreement in effect from August 24, 2012 to January 1, 2013, ECF No. 

187-6 at 2-17; and (2) a covenant not to sue (“CNTS”) that operated from January 2, 2013 until 

February 9, 2015, id. at 19-21. In its opposition, Asetek concedes that the licensing agreement at 

least “arguably granted Corsair [the licensee] the right to make or have made products covered by 

Asetek’s patents without any marking requirement.” ECF No. 203 at 23. Accordingly, Asetek 

now disclaims any right to infringement damages prior to January 2, 2013. Id. The Court 

therefore turns to the effect of the CNTS.

In the CNTS, Asetek agreed not to sue Corsair for its sale of products supplied by CoolIT. 

ECF No. 187-6 at 19. At the time, Asetek was pursuing infringement claims against CoolIT and 

affiliated entities in this district. See Asetek Holdings, Inc. v. Coolit Systems, Inc., 12-cv-04498-

EMC. The CNTS terminated by its own terms upon resolution of that litigation. ECF No. 187-6 

at 19-20. 

Though Asetek contests whether any sales protected by the CNTS were “for or under” 

Asetek, ECF No. 203 at 27, the Court assumes without deciding that the CNTS effectively 

extended a license to Corsair to sell the allegedly infringing CoolIT products. See TransCore, LP 

v. Elec. Transaction Consultants Corp., 563 F.3d 1271, 1275 (Fed. Cir. 2009) (explaining that 

“this court and its predecessors have on numerous occasions explained that a non-exclusive patent 

 

22 On reply, AVC argues for the first time that the Court should impose discovery sanctions 

– including striking Asetek’s claims for damages prior to May 15, 2017 – for “Asetek’s intentional 

failure to provide requested samples and records” in response to AVC’s request for documents 

“sufficient to show patent marking and/or virtual patent marking.” ECF No. 208-5 at 17. The 

Court ordinarily disfavors new arguments on reply. See Hefler v. Wells Fargo & Co., No. 16-CV05479-JST, 2018 WL 1070116, at *9 (N.D. Cal. Feb. 27, 2018) (citing Ass’n of Irritated Residents 

v. C & R Vanderham Dairy, 435 F.Supp.2d 1078, 1089 (E.D. Cal. 2006)). Regardless, AVC’s 

cursory argument does not appear to demonstrate any violation of Asetek’s discovery obligations, 

particularly in light of the above discussion of the evidence “sufficient to show patent marking.” 

If Asetek later attempts to rely on additional records that AVC believes should have been 

produced in discovery, AVC may seek the appropriate relief at that time.

license is equivalent to a covenant not to sue”). The Court therefore applies the ““rule of reason’

inquiry” to determine whether Asetek’s efforts were “consistent with the purpose of the 

constructive notice provision – to encourage patentees to mark their products in order to provide 

notice to the public of the existence of the patent and to prevent innocent infringement.” Arctic 

Cat, 876 F.3d at 1366 (quoting Maxwell, 86 F.3d at 1112).

In light of the then-active litigation regarding whether the CoolIT products infringed 

Asetek’s patents, the Court finds that the CNTS represented “reasonable efforts to ensure 

compliance with the marking requirements.” Maxwell, 86 F.3d at 1112. At the time, it would 

have been unreasonable for Asetek to attempt to impose marking requirements on any CoolIT 

products supplied to Corsair because there was an active dispute whether those products were 

Asetek’s “patented article[s].” 35 U.S.C. § 287(a); cf. Arctic Cat, 876 F.3d at 1367-69 (discussing 

the evidentiary burdens associated with the threshold question whether products “are unmarked 

‘patented articles’ subject to § 287”). The CNTS was structured so that its effective license to 

Corsair lasted only as long as that question remained unsettled. See ECF No. 187-6 at 19-20. 

Stated differently, the CNTS at most licensed the sale of products that Asetek could not prove it 

had a right to mark. Accordingly, the Court holds that unmarked products sold under the auspices 

of the CNTS do not undermine Asetek’s compliance with § 287(a)’s marking requirements.

Because there are genuine disputes of fact whether Asetek marked substantially all of its 

patented articles, the Court denies AVC’s motion for summary judgment on this issue.

D. Remaining Issues

Finally, AVC seeks summary judgment on the priority date of the ’362 patent and AVC’s 

liability for Asetek’s lost profits. ECF No. 186 at 26-31. In response, Asetek contends that 

neither issue is in dispute in this case and urges the Court not to decide them, given that those 

issues may arise as actual disputes in other litigation involving these patents. ECF No. 203 at 29. 

AVC’s reply identifies no claim in this case that would be impacted by the resolution of these 

issues. See ECF No. 207 at 18. In light of Asetek’s concessions, the Court need not decide these 

questions.

CONCLUSION

To recap, the Court GRANTS Asetek’s motion to strike portions of Dr. Clarksean’s expert 

rebuttal report and Dr. Joshi’s declaration, but DENIES as moot the motion to strike Dr. 

Clarksean’s declaration. The Court GRANTS Asetek’s partial motion for summary judgment that 

(1) the claims of the ’362 and ’764 patents are not invalid and (2) that AVC’s equitable defenses to 

infringement fail. Finally, the Court DENIES AVC’s partial motion for summary judgment on 

induced infringement, contributory infringement, willful infringement, extraterritorial sales, and 

marking compliance. The Court does not reach the questions of the ’362 patent’s priority date or 

Asetek’s lost profits.

IT IS SO ORDERED.
