[Re: Docket Nos. 41 and 47]

Defendants VIA Technologies, Inc. and VIA Technologies, Inc. (USA) (collectively

“VIA”) moved to strike certain portions of the “Supplemental Disclosure of Asserted Claims

and Preliminary Infringement Contentions” (“Supplemental PICs”) served by plaintiff

Computer Cache Coherency Corporation (“CCCC”). CCCC opposed the motion to strike and

filed a cross-motion for leave to amend its PICs. Upon consideration of the papers submitted by

the parties, as well as the arguments presented at the March 28, 2006 hearing, this court

GRANTS VIA’s motion to strike and DENIES CCCC’s motion for leave to amend.

1 The instant action has been consolidated through claims construction with

Computer Cache Coherency Corp. v. Intel Corp., No. C05-01766 RMW (HRL). 

However, CCCC has not served supplemental PICs in the Intel action, and the instant

motions concern only CCCC’s lawsuit against VIA.

2

I. BACKGROUND

This is an action for alleged patent infringement.1

 CCCC alleges that VIA infringes

CCCC’s U.S. Patent No. 5,072,369 (the “‘369 patent”). The ‘369 patent contains three claims: 

one independent claim (Claim 1) and two dependent claims (Claims 2 and 3). According to

CCCC, the claimed invention(s) pertain to an electronic circuit which serves as an interface

between different computer components. It claims that VIA manufactures computer products

known as “chipsets” which infringe the ‘369 patent.

Patent L.R. 3-1 provides that a party claiming infringement must serve PICs containing

certain information, including identification of “[e]ach claim of each patent in suit that is

allegedly infringed by each opposing party” and for each identified claim, “each accused

apparatus, product, device, method, act or other instrumentality (‘Accused Instrumentality’) of

each opposing party of which the party [claiming infringement] is aware.” PATENT L.R. 3-1(a),

(b).

On September 19, 2005, CCCC served its PICs, asserting Claim 1 of the ‘369 patent

against twenty-eight VIA products. By letter dated October 10, 2005, VIA’s counsel identified

a number of alleged deficiencies in CCCC’s PICs. Among other things, VIA asserted that the

PICs briefly addressed only one product, and therefore failed to provide sufficient support for

CCCC’s allegation that the other twenty-seven identified products also infringe Claim 1 of the

‘369 patent. (See Declaration of Jennifer Ochs (“Ochs Decl.”), Ex. 3). CCCC responded that it

believed that all twenty-eight accused products “work[] identically” and that it therefore was

not obliged to “replicate claim charts for each accused product . . ..” (Id., Ex. 6). While it

maintained that its PICs were proper, CCCC agreed to “duplicate its work” and provide

supplemental PICs. (Id.).

On December 2, 2005, without leave of court, CCCC served its Supplemental PICs,

asserting Claims 2 and 3 of the ‘369 patent (in addition to Claim 1 asserted in its initial PICs).

2 VIA asserts that CCCC’s Supplemental PICs not only contain the same

deficiencies as its initial PICs, but also suffer from additional defects. However, VIA has

chosen not to address these issues on the instant motion and says that it will do so through

dispositive motions or some other appropriate relief.

3

The Supplemental PICs also identified sixteen accused products in addition to the twenty-eight

products identified in the initial PICs.

VIA now moves to strike patent Claims 2 and 3 and the sixteen newly identified accused

products from CCCC’s Supplemental PICs.2 It contends that CCCC amended its PICs in bad

faith and without leave of court in violation of the Patent Local Rules. VIA further argues that

it has been prejudiced by CCCC’s improper disclosure. CCCC counters that there is no

prejudice to VIA, and argues that there is good cause for allowing it to proceed with its

Supplemental PICs. The parties’ arguments made in support of and in opposition to their

respective motions are the same, and the court will treat both motions together in this order.

II. DISCUSSION

Although CCCC seems to suggest that it was entitled to amend its PICs without leave of

court, under Patent L.R. 3-7, PICs may only be amended or modified by court order upon a

showing of good cause. PATENT L.R. 3-7. There is an exception for amendments made

pursuant to Patent L.R. 3-6, which provides that a party claiming infringement may amend its

PICs without leave of court if that party believes in good faith that such an amendment is

required by (1) the court’s claim construction ruling or (2) documents accompanying an accused

infringer’s preliminary invalidity contentions. PATENT L.R. 3-6(a). However, such

amendments are limited to information required by Patent L.R. 3-1(c) and (d) – that is, (1) the

claim chart identifying where each element of each asserted claim is found within each accused

product; and (2) identification as to whether each element of each asserted claim is claimed to

be infringed literally or under the doctrine of equivalents. PATENT L.R. 3-1(c), (d); 3-6(a). A

party’s PICs are otherwise “deemed to be that party’s final contentions.” PATENT L.R. 3-6.

This court is not persuaded that the conditions for amendment under Civ. L.R. 3-6(a)

exist. In its papers, CCCC did not argue that such circumstances were presented here; and for

the first time at the hearing, its counsel offered only a very generalized statement that the

amendment was prompted, in part, by non-public design documents defendant produced,

including (possibly) documents produced in the course of settlement negotiations. Even if the

requisite conditions under Patent L.R. 3-6(a) did exist, that rule does not appear to contemplate

the amendments sought by CCCC, i.e., to assert additional patent claims and identify more

accused products. CCCC suggests that VIA cannot complain because it asked CCCC to

supplement its initial PICs. This argument fails to convince. The record presented shows that

VIA believed supplementation was required as to the claims and products that had already been

identified in CCCC’s initial PICs. There was no indication that CCCC intended (or

communicated any intent) to supplement its PICs to include more patent claims and products –

that is, until it served its Supplemental PICs on December 2, 2005. (See Ochs Decl., Exs. 3 and

6).

Nevertheless, CCCC now seeks leave of court to amend its PICs (albeit, CCCC’s

motion, which was filed only after VIA filed its motion to strike, appears to have been an

afterthought). There are few cases which discuss the “good cause” standard under Patent L.R.

3-7. The parties have cited, and this court has found, only two published cases in this district

which address that rule. The import of those opinions is that the Patent Local 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.’” Integrated Circuit Sys., Inc. v.

Realtek Semiconductor Co., Ltd., 308 F. Supp.2d 1106, 1107 (N.D. Cal. 2004) (quoting Atmel

Corp. v. Info. Storage Devices, Inc., 1998 WL 775115 at *2-3 (N.D. Cal., Nov. 5, 1998)); LG

Electronics, Inc. v. Q-Lity Computer, Inc., 211 F.R.D. 360, 367 (N.D. Cal. 2002). This

deviation from the general policy of favoring liberal amendment in civil actions was intended to

avoid the “‘shifting sands’ approach which sometimes occurred during the claim construction

process prior to the enactment of the Patent Local Rules.” Integrated Circuit Sys., Inc., 308 F.

Supp.2d at 1107; LG Electronics, 211 F.R.D. at 367.

In the instant case, CCCC asserts that because its initial PICs identified accused chipsets

by family – i.e., VIA’s K8, Mature and Legacy chipsets – the identification of additional

product numbers falling within those same families does not constitute the identification of

“additional” products. As such, it argues that the newly identified product numbers in the

Supplemental PICs should come as no surprise to VIA. CCCC further contends that VIA’s

product classifications are confusing, and says that it included specific product numbers in its

PICs simply for “clarity.” In other words, CCCC suggests that its initial PICs demonstrate an

intent to accuse products by family, and not by specific product number.

This court finds this contention to be disingenuous at best. While CCCC argues that

VIA’s product classifications are confusing (an assertion which VIA disputes), the record

presented demonstrates that the way in which VIA categorizes its products is, for purposes of

resolving the instant motion, irrelevant. CCCC’s initial PICs identify VIA’s K8, Mature and

Legacy product families, but there is nothing in the initial PICs which suggests that CCCC

intended to allege infringement by products other those which are specifically listed by number

within those family groups. (See Supplemental Declaration of Jennifer Ochs (“Supp. Ochs

Decl.”), Ex. 19). Indeed, CCCC eliminated the family group designations altogether in its

Supplemental PICs. (See id., Ex. 20). Further, CCCC acknowledges that is initial PICs did not

include one additional chipset in the P4 family which it says should now be allowed by

amendment, adding that all other products from the P4 family were previously identified,

although not expressly designated as being part of the P4 family. In any event, at least one

court in this district has observed that “[r]equiring or even permitting a plaintiff to amend or

supplement its disclosures as it discovers new products would remove the claim construction

process from the control of the court and signal a return to the ‘shifting sands’ approach” which

the Patent Local Rules were designed to prevent. Integrated Circuit Sys., Inc., 308 F. Supp.2d

at 1107.

As for CCCC’s desire to now assert Claims 2 and 3 of the ‘369 patent, CCCC

acknowledges that at the time it served its initial PICs, it did not believe that there was a

sufficient basis for accusing VIA’s products of infringing those claims. VIA attests that the

names of all of its chipsets have long been publicly available on its website. (See Ochs Decl.,

¶¶ 20-21, Exs. 17-18). Further, VIA contends that CCCC, having had an opportunity to review

VIA’s November 3, 2005 preliminary invalidity contentions, belatedly seeks to assert patent

Claims 2 and 3 in an attempt to dodge what VIA believes to be a strong invalidity case on

Claim 1.

CCCC protests that VIA’s contention is unfounded, but CCCC also makes no showing

to support its bare assertion that it acted with diligence in investigating VIA’s products with

respect to Claims 2 and 3 of the ‘369 patent. CCCC does not say what diligence it used before

it served its initial PICs. Nor does it identify when it began “its further investigation and

analysis of Via’s accused products” (Opp. at 6:4). Indeed, CCCC’s papers indicate that its

investigation may have been undertaken only after it served its initial PICs. Here, CCCC states

that its amendment was “based on a diligent and good faith investigation of Via’s products since

its initial PICs.” (Id. at 6:8). As noted above, CCCC asserted for the first time at the hearing

that its Supplemental PICs were based, in part, on some non-public design documents produced

by VIA. However, it has not pointed to any specific information disclosed by VIA which

would justify giving leave to assert the additional claims and relies primarily upon

generalizations in arguing about the accused products it seeks to add. Further, CCCC does not

explain why, despite the exercise of reasonable diligence, it could not assert Claims 2 and 3

earlier.

In sum, CCCC simply asserts that it has found more evidence of infringement as

discovery and its own investigations have continued. This court is not persuaded that such

circumstances, in and of themselves, constitute good cause for adding more claims and products

now.

CCCC nevertheless attempts to establish “good cause” primarily by arguing that there is

no prejudice to VIA. Although this court has found no Ninth Circuit authority on what

constitutes “good cause” to amend a party’s PICs under this court’s Patent Local Rules, the

Ninth Circuit has discussed the meaning of “good cause” in the context of a motion to amend a

scheduling order under Fed.R.Civ.P. 16. It stated that “[a]lthough the existence or degree of

prejudice to the party opposing the modification might supply additional reasons to deny a

motion, the focus of the inquiry is upon the moving party’s reasons for seeking modification.” 

Johnson v. Mammoth Recreations, Inc., 975 F.2d 604, 609 (9th Cir. 1992). “If that party was

3 As noted by VIA, the District Court for the Eastern District of Texas

not diligent, the inquiry should end.” Id.; see also STMicroelectronics, Inc. v. Motorola, Inc.,

307 F. Supp.2d 845, 851 (E.D. Tex. 2004) (finding that “good cause” focuses on the diligence

of the party requesting amendment, and not on the lack of prejudice to the opposing party).3

In any event, CCCC fails to convincingly demonstrate that VIA’s assertions of prejudice

are baseless. Here, VIA maintains that it will be prejudiced by the requested amendments in

that (1) the parties’ claim construction statements and briefs do not include additional terms

from Claims 2 and 3 which VIA believes need to be construed; (2) VIA will be forced to

undertake another, and broader, prior art search with respect to particular claim limitations in

Claims 2 and 3; (3) VIA will be obliged to undertake its own independent analysis of the

additional accused products; and (4) VIA will need to amend its preliminary invalidity

contentions, which currently do not address patent Claims 2 and 3.

CCCC argues that there is ample time in the case management schedule to accommodate

the preparation and service of supplemental preliminary invalidity contentions by VIA, as well

as any additional briefing on claim construction issues. The parties have already exchanged

statements and filed their respective claim construction briefs as to terms in Claim 1 of the ‘369

patent (i.e., the only claim asserted by CCCC in its initial PICs). However, CCCC stated that at

the March 24, 2006 case management conference, the District Court pushed the April 25-26,

2006 Markman hearing and tutorial and indicated that it will entertain dispositive motions in

early May 2006.

CCCC also argues that, if there is any prejudice, it was the result of VIA’s own conduct

because VIA chose not to address patent Claims 2 and 3 earlier and did not complain about

CCCC’s Supplemental PICs until January 19, 2006. Here, CCCC contends that VIA had

sufficient time to apprise the court of terms from Claims 2 and 3 for construction because the

Supplemental PICs were served on December 2, 2005 – i.e., seven days before the parties

exchanged Preliminary Proposed Claim Construction statements, over a month before the

parties filed their Joint Claim Construction Statement, and more than three months before VIA

was obliged to file its claim construction statement. Additionally, CCCC says that it has no

objection if VIA wishes to amend its preliminary invalidity contentions to address Claims 2 and

3.

However, the premise of CCCC’s argument is that VIA was obliged to address the

newly asserted patent claims, despite the fact that the Supplemental PICs were served without

the requisite leave of court. While CCCC apparently agrees that VIA may supplement is

preliminary invalidity contentions, VIA contends that, as the prejudiced party, it should not be

forced to bear the substantial burden that will be imposed, particularly where CCCC’s

Supplemental PICs were served contrary to the Patent Local Rules and without good cause.

Based upon the circumstances presented, this court finds VIA’s arguments to be more

persuasive than CCCC’s arguments and concludes that CCCC has failed to show good cause for

amending its infringement contentions to add more patent claims and more products.

III. ORDER4

Based on the foregoing, IT IS ORDERED THAT:

1. VIA’s motion to strike Claims 2 and 3 and sixteen additional products from

CCCC’s Supplemental PICs is GRANTED.

2. CCCC’s cross-motion for leave to amend its PICs is DENIED.
