2 SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC

Before CHEN, HUGHES, and CUNNINGHAM, Circuit Judges.

CUNNINGHAM, Circuit Judge.

SmartSky Networks, LLC (“SmartSky”) appeals from 

the decision of the United States District Court for the District of Delaware denying SmartSky’s motion for preliminary injunction filed against Gogo Business Aviation, LLC

and Gogo Inc. (collectively, “Gogo”). J.A. 2–21 (Decision). 

The district court found that SmartSky failed to meet its 

burden to establish that it is likely to succeed on the merits 

and that it is likely to suffer irreparable harm if a preliminary injunction is not granted. J.A. 13, 16–18, 21. Because 

the district court did not abuse its discretion in finding that 

SmartSky failed to meet its burden of establishing irreparable harm, we affirm. 

I. BACKGROUND

Gogo and SmartSky are competitors as business aviation network providers, both offering air-to-ground (“ATG”) 

networks that provide broadband in-flight internet connections to aircrafts. J.A. 21; Appellant’s Br. 4–7; Appellee’s 

Br. 5–7. On February 28, 2022, SmartSky sued Gogo, alleging that Gogo’s 5G network infringes claims of SmartSky’s U.S. Patent Nos. 9,312,947, 11,223,417, 10,257,717, 

and 9,730,077 (collectively, the “asserted patents”). J.A. 3; 

J.A. 103. The asserted patents relate to technology that 

enables wireless in-flight internet connections. See ’947 

patent; ’417 patent; ’717 patent; ’077 patent. At the time 

of the latest filings with this court, Gogo’s 5G network was 

not yet operational. Oral Arg. at 13:53–14:08, available at 

https://oralarguments.cafc.uscourts.gov/default.aspx?fl=

23-1058_06052023.mp3; ECF No. 59 at 5 (Gogo’s Opposition to SmartSky’s Motion for Leave to Supplement the 

Record on Appeal). 

On the same day as filing the complaint, SmartSky 

moved to preliminary enjoin Gogo from making, using, offering to sell, or selling its 5G network. J.A. 3. SmartSky 

Case: 23-1058 Document: 63 Page: 2 Filed: 01/31/2024
SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC 3

contended that it was likely to successfully prove that 

Gogo’s 5G network infringes claims 1 and 11 of the ’947 patent, claims 1 and 11 of the ’417 patent, claims 1 and 12 of 

the ’717 patent, and claims 1 and 2 of the ’077 patent, and 

that these claims are not likely to be found invalid. J.A. 

162–65. SmartSky further asserted that it was likely to 

suffer irreparable harm absent a preliminary injunction. 

J.A. 166. On September 26, 2022, the district court denied 

SmartSky’s motion for preliminary injunction, finding 

SmartSky had not established a likelihood of success on the 

merits for any of the asserted patents and had not shown 

that it was likely to suffer irreparable harm. J.A. 2–21. 

SmartSky timely appealed. We have jurisdiction under 28 U.S.C. § 1292(c)(1).

II. STANDARD OF REVIEW

We review a denial of a preliminary injunction according to the law of the regional circuit—here, the Third Circuit—but “give[] dominant effect to Federal Circuit 

precedent insofar as it reflects considerations specific to patent issues.” Nippon Shinyaku Co. v. Sarepta Therapeutics, Inc., 25 F.4th 998, 1004 (Fed. Cir. 2022) (citation

omitted). Under both Federal Circuit and Third Circuit 

law, we review the denial of a preliminary injunction for an 

abuse of discretion. Id. (citations omitted); see Kos 

Pharms., Inc. v. Andrx Corp., 369 F.3d 700, 708 (3d Cir. 

2004) (citation omitted). “An abuse of discretion may be 

established by showing that the court made a clear error of 

judgment in weighing relevant factors or exercised its discretion based upon an error of law or clearly erroneous factual findings.” Koninklijke Philips N.V. v. Thales DIS AIS 

USA LLC, 39 F.4th 1377, 1379 (Fed. Cir. 2022) (quoting 

Novo Nordisk of N. Am., Inc. v. Genentech, Inc., 77 F.3d 

1364, 1367 (Fed. Cir. 1996)); see Kos Pharms., 379 F.3d at 

708. 

“To obtain a preliminary injunction, a party must establish that it is likely to succeed on the merits, that it is 

Case: 23-1058 Document: 63 Page: 3 Filed: 01/31/2024
4 SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC

likely to suffer irreparable harm in the absence of preliminary relief, that the balance of equities tips in its favor, and 

that an injunction is in the public interest.” Koninklijke, 

39 F.4th at 1379–80 (cleaned up) (citation omitted); see Kos 

Pharms., 369 F.3d at 708 (citation omitted). 

III. DISCUSSION

A.

Before addressing SmartSky’s arguments on the merits, we first address SmartSky’s two motions for leave to 

supplement the record with certain materials not reviewed 

by the district court. ECF No. 33 (Motion to Supplement)

at 3; ECF No. 58 (Second Motion to Supplement) at 3; see 

Appellant’s Reply Br. 23, 25–27, 31 (citing extra-record materials). The materials subject to the motion to supplement

include: (1) Gogo’s Annual Report for 2022 (Form 10-K); 

(2) Gogo’s 2022 Fourth Quarter Report and 2023 Q3 Report 

(Forms 8-K); (3) Gogo’s 2023 Third Quarter Report (Form 

10-Q); (4) the transcripts of Gogo’s 2022 Q4 Earnings Call

and Gogo’s 2023 Q3 Earnings call; (5) publicly available 

statements made by Gogo’s CEO during a podcast interview; and (6) a publicly-available press release issued by 

Gogo on October 17, 2023. ECF No. 33 at 3; ECF No. 58 at 

3. SmartSky requests this court to grant the motion to supplement, or alternatively, take judicial notice of the extrarecord, publicly available materials, arguing that these 

documents would establish certain facts about Gogo’s allegedly infringing equipment relevant to irreparable harm

and would directly contradict Gogo’s arguments. See, e.g., 

ECF No. 33 at 3, 7, 10; ECF No. 58 at 3, 7, 8, 10–12. 

We deny SmartSky’s motions to supplement. We “will 

not consider new evidence on appeal absent extraordinary 

circumstances, such as those that render the case moot or 

alter the appropriateness of injunctive relief, a change in 

pertinent law, or facts of which a court may take judicial 

notice.” In re Application of Adan, 437 F.3d 381, 388 n.3

(3d Cir. 2006), abrogated on other grounds by Golan v. 

Case: 23-1058 Document: 63 Page: 4 Filed: 01/31/2024
SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC 5

Saada, 142 S. Ct. 1880 (2022). We likewise strike the relevant portions of SmartSky’s reply brief citing these extrarecord materials. Appellant’s Reply Br. 23, 25–27, 31. See 

Am. Standard Inc. v. Pfizer Inc., 828 F.2d 734, 746 (Fed. 

Cir. 1987) (striking references to material not considered 

by the district court and not properly supplemented). 

SmartSky asserts that the extra-record documents are 

relevant to establishing market share, sales, and switching 

costs from one provider to another. ECF No. 33 at 13–14,

20; ECF No. 58 at 4–5, 11–12. But the district court found 

no likelihood of irreparable harm despite finding that 

SmartSky established consumer “stickiness” and that Gogo 

and SmartSky “compete[] directly.” J.A. 21. Any extra-record materials directed to these facts would not “alter the 

appropriateness of injunctive relief.” In re Adan, 437 F.3d 

at 388 n.3. SmartSky also does not argue that there is a 

change in pertinent law or a mooting event that would justify SmartSky’s motion to supplement. See id. 

We also decline to take judicial notice of SmartSky’s 

extra-record materials. Judicial notice exists to take notice

of “fact[s] that [are] not subject to reasonable dispute,” Fed. 

R. Evid. 201(b). Here, parties reasonably dispute the accuracy and relevance of the facts SmartSky seeks to establish

from these extra-record materials. Compare ECF No. 33 at 

7 (arguing that Gogo’s alleged facts presented to the district court and this court are at odds with the information 

in the extra-record materials), and ECF No. 58 at 12–13

(arguing that the extra-record materials contradict the district court’s finding of no imminent lost sales), with ECF 

No. 35 at 9–11 (responding that Gogo’s arguments do not 

contradict the supplemental materials), and ECF No. 59 at

5–6 (responding that the extra-record materials do not contradict the district court’s findings). Because the “proper 

function of a court of appeals is to review the decision below 

on the basis of the record that was before the district court,” 

under these specific circumstances, we decline to take judicial notice of the materials subject to the motions to 

Case: 23-1058 Document: 63 Page: 5 Filed: 01/31/2024
6 SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC

supplement. Moore v. City of Phila., 461 F.3d 331, 344 n.5 

(3d Cir. 2006), as amended (Sept. 13, 2006) (internal quotation marks omitted) (quoting Fassett v. Delta Kappa Epsilon (New York), 807 F.2d 1150, 1165 (3d Cir. 1986)). 

B.

SmartSky argues the district court erred by: (1) finding no likelihood of success on the merits, Appellant’s Br. 

28, 31, 37, 42; and (2) holding that SmartSky failed to establish a likelihood of irreparable harm. Id. at 42. Because 

we hold that the district court did not abuse its discretion 

in finding SmartSky failed to establish a likelihood of irreparable harm, we affirm the district court’s denial of a 

preliminary injunction. Because we find no reversible error as to the district court’s findings as to irreparable harm, 

we do not need to also address SmartSky’s arguments related to likelihood of success. See Roper Corp. v. Litton 

Sys., Inc., 757 F.2d 1266, 1271 (Fed. Cir. 1985) (affirming 

denial of preliminary injunction without addressing likelihood of success with respect to infringement because movant “clearly failed to meet the criterion of showing 

irreparable injury”). 

SmartSky has the burden of establishing that it is 

likely to suffer irreparable harm absent a preliminary injunction and that there is a causal nexus between the alleged infringement and the alleged harm. Metalcraft of 

Mayville, Inc. v. Toro Co., 848 F.3d 1358, 1368 (Fed. Cir. 

2017) (citing Apple Inc. v. Samsung Elecs. Co., 735 F.3d 

1352, 1360 (Fed. Cir. 2013) (“Apple I”)). Where no amount 

of monetary damages could address the harm, the harm is 

likely irreparable. Id. (citing Celsis In Vitro, Inc. v. 

CellzDirect, Inc., 664 F.3d 922, 930 (Fed. Cir. 2012)). On 

the other hand, “[t]he mere possibility or speculation of 

harm is insufficient.” Koninklijke, 39 F.4th at 1380 (citation omitted). Price erosion, loss of goodwill, damage to 

reputation, and loss of business opportunities are examples 

Case: 23-1058 Document: 63 Page: 6 Filed: 01/31/2024
SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC 7

of possible grounds for finding irreparable harm. Celsis, 

664 F.3d at 930. 

SmartSky contends that the district court erred by

finding that it did not establish a likelihood of irreparable 

harm from (1) lost sales and lost market share, (2) price 

erosion, (3) lost reputation and goodwill, and (4) lost research and development (“R&D”) and investments. Appellant’s Br. 49, 55, 57, 58. SmartSky also argues that this 

case includes “hallmark examples of irreparable harm” and 

the district court abused its discretion by ignoring such 

hallmarks. Id. at 42–43, 51. We address each argument in 

turn. 

i. 

SmartSky asserts that the district court erred in finding no irreparable harm and that SmartSky had not

demonstrated that lost sales and lost market share were 

“imminent as a result of Gogo’s yet-to-be-released 5G Network or that its losses are non-compensable.” Appellant’s 

Br. 49 (quoting J.A. 21). Regarding lost sales, SmartSky 

argues that the district court erred in finding that Gogo’s 

accused 5G network was “yet-to-be released” when Gogo 

has made sales on its accused 5G network since at least

October 2021. Id. at 50. SmartSky also contends that the 

district court ignored Gogo’s sales of AVANCE L5 equipment. Id. Additionally, SmartSky argues that the district 

court’s irreparable harm findings were inconsistent with 

finding SmartSky and Gogo to be “direct competitors” and 

finding Gogo’s consumers to be “sticky.” Id. at 46–47, 48–

49. Lastly, SmartSky contends that the district court erred 

in disregarding Gogo’s market advantage based on firstmover advantage and monopoly position and failing to 

credit SmartSky’s expert testimony that the lost sales and 

market share were unquantifiable. Id. at 52–54. 

We find SmartSky’s lost sales arguments unpersuasive

as to Gogo’s 5G network. SmartSky itself concedes that 

Gogo’s 5G network has not been released. Oral Arg. at 

Case: 23-1058 Document: 63 Page: 7 Filed: 01/31/2024
8 SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC

13:53–14:08. SmartSky also does not dispute that Gogo

has not launched its 5G network even in one of its most 

recent filings with the court. ECF No. 60 at 3. Even accepting SmartSky’s argument that the district court should 

have relied on evidence that Gogo’s accused 5G network 

has been offered for sale since October 2021, Appellant’s 

Br. 50, the district court did not abuse its discretion in finding that any lost sales and service revenue through the 

date of trial is quantifiable because SmartSky’s own expert

conceded to this conclusion. J.A. 19, 21; J.A. 6922–23. See 

Abbott Lab’ys v. Andrx Pharms., Inc., 452 F.3d 1331, 1348 

(Fed. Cir. 2006) (holding potential lost sales alone did not 

demonstrate manifest irreparable harm). We are further 

unpersuaded that the district court erred in not crediting 

SmartSky’s expert testimony that certain damages are unquantifiable after trial. Appellant’s Br. 54–55. Considering SmartSky’s concession and its expert’s own admission, 

we disagree that the district court abused its discretion in 

finding no likelihood of irreparable harm. 

As for any lost sales from AVANCE L5, SmartSky 

failed to raise this argument in its opening brief at the district court. Op. Prelim. Inj. Br. 12–18, SmartSky Networks, 

LLC v. Gogo Business Aviation, LLC, No. 1:22-cv-00266 (D.

Del. Mar. 22, 2022), D.I. 24. SmartSky thus failed to preserve this argument for appeal by “rais[ing] [it] for the first 

time before a district court in a reply brief.” In re Niaspan 

Antitrust Litig., 67 F.4th 118, 135 (3d Cir. 2023); see

Novosteel SA v. United States, 284 F.3d 1261, 1273 (Fed. 

Cir. 2002) (deeming issue not preserved for review because 

it was not raised in a principal brief at the Court of International Trade). But even if we were to consider SmartSky’s argument, we are not persuaded. As SmartSky 

concedes, AVANCE L5 is currently sold as part of Gogo’s

unaccused 4G network. Oral Arg. at 29:45–53. The fact 

that AVANCE L5 is also a “necessary component” of the 

allegedly infringing 5G network is immaterial, id. at 

12:50–13:01, because a customer must choose to upgrade 

Case: 23-1058 Document: 63 Page: 8 Filed: 01/31/2024
SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC 9

its AVANCE L5 before it can be used with Gogo’s 5G network. J.A. 1368, 1384; J.A. 4766; J.A. 9594. Here, the alleged harm will only occur if Gogo launches its 5G network 

and if customers of AVANCE L5 choose to upgrade. “This 

type of speculative harm does not justify the rare and extraordinary relief of a preliminary injunction.” Koninklijke, 39 F.4th at 1380. 

SmartSky further contends that the district court correctly acknowledged that the parties are in direct competition and that there is consumer stickiness in the market, 

but still erred by finding that SmartSky was not likely to 

show irreparable harm. J.A. 21; Appellant’s Br. 46–49. We 

disagree. SmartSky has not pointed us to any additional

evidence in the record that suggests that any consumers 

who chose Gogo’s 5G network would have chosen SmartSky’s product rather than, for example, Gogo’s unaccused 

4G product or a non-infringing product offered by another 

provider of in-flight connectivity service. Furthermore, although “the existence of a two-player market may . . . create[] an inference that an infringing sale amounts to a lost 

sale for the patentee,” Robert Bosch LLC v. Pylon Mfg. 

Corp., 659 F.3d 1142, 1151 (Fed. Cir. 2011), SmartSky’s argument fails because the district court never made a finding that SmartSky and Gogo are the only two competitors 

in the relevant market. Rather, the district court merely

found SmartSky and Gogo “compete[] directly” as “business 

aviation network provider[s].” J.A. 21. The record suggests that the market for business aviation network providers may contain many more players than SmartSky and 

Gogo, including providers that use non-ATG technologies 

to provide in-flight connectivity services. J.A. 7566. Therefore, the district court did not abuse its discretion in finding 

that SmartSky’s alleged losses were not sufficiently imminent or non-compensable based on Gogo’s yet-to-be-released 5G network. 

Nor are we persuaded by SmartSky’s citation of cases 

where the court found irreparable harm based on the 

Case: 23-1058 Document: 63 Page: 9 Filed: 01/31/2024
10 SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC

alleged infringer’s market positions. Appellant’s Br. 52–53

(citing cases). In these cases, the causal connections between the alleged infringer’s market position and the alleged infringement were more pronounced. For example, 

in Bio-Rad Laboratories, Inc. v. 10X Genomics Inc., the 

court identified testimony that the alleged infringer left the 

patentee to start the company that made the accused product, leading to the alleged infringer’s “first mover advantage.” 967 F.3d 1353, 1378 (Fed. Cir. 2020). In 

Broadcom Corp. v. Emulex Corp., the “incumbency effect” 

arose from the “design wins” market—not present here—

where a manufacturer “essentially commits itself to a single supplier until the next design cycle,” leading to a market where the alleged infringer could obtain serious 

dominance. 732 F.3d 1325, 1336–37 (Fed. Cir. 2013). Likewise, in M-I LLC v. FPUSA, LLC, a non-precedential case,

the parties were in a two-player market, which the district 

court has not found here. 626 F. App’x 995, 998–99 (Fed. 

Cir. 2015); J.A. 21. SmartSky has not presented evidence 

that circumstances similar to these cases exist here. Accordingly, these cases are inapposite.

For the reasons above, we conclude the district court 

did not abuse its discretion in rejecting SmartSky’s argument that its alleged lost sales and lost market share

amounted to irreparable harm. 

ii. 

SmartSky also argues that the district court erred in

deeming its price erosion theory of irreparable harm speculative by ignoring testimony from SmartSky’s president

alleging that customers used Gogo’s pricing to negotiate 

price reductions from SmartSky. Appellant’s Br. 55–56. 

We find this argument unpersuasive. In previous 

cases, we have required concrete evidence of reduced price 

to find price erosion. For example, in Sanofi-Synthelabo v. 

Apotex, Inc., we found no abuse of discretion in finding that 

the patentee would suffer price erosion due to a complex 

Case: 23-1058 Document: 63 Page: 10 Filed: 01/31/2024
SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC 11

price scheme affected by the entry of a generic product to 

the market. 470 F.3d 1368, 1382 (Fed. Cir. 2006). In Robert 

Bosch, we explained, among other things, that the patentee 

“offered a new, cheaper [product] in an attempt to compete 

with [the alleged infringer]’s lower prices” in holding the 

district court erred in its finding of no irreparable harm. 

659 F.3d at 1153–54. Such concrete evidence is not present 

in the testimony of SmartSky’s president. The cited testimony shows that a few potential customers requested a 

price decrease in light of Gogo’s 4G network pricing, not 

that SmartSky lowered its price because of the launch of 

Gogo’s 5G network. J.A. 9594, 9597–99, 9602–03. Furthermore, SmartSky’s president conceded that SmartSky set 

its prices before Gogo announced the prices of its 5G network. J.A. 9591–93. Therefore, the district court did not 

abuse its discretion by rejecting SmartSky’s price erosion 

argument as speculative. 

SmartSky further argues that the district court ignored the testimony of SmartSky’s expert, Mr. Cook. Appellant’s Reply Br. 29–30. We agree with the district court 

that Mr. Cook “offer[ed] no economic analysis, other than 

conclusory assertions, to support its price erosion theory.” 

J.A. 20; see J.A. 302–03 (expert report); J.A. 8125–27 (rebuttal expert report). We see no abuse of discretion in the 

district court’s rejection of this testimony. See Nichia Corp. 

v. Everlight Americas, Inc., 855 F.3d 1328, 1342–43 (Fed. 

Cir. 2017) (rejecting price erosion theory where the expert 

did not attempt a price-erosion analysis). 

iii. 

SmartSky also argues that the district court erred in

finding that SmartSky did not demonstrate irreparable 

harm to its reputation and goodwill. Appellant’s Br. 58–

60. We disagree. 

SmartSky’s president attributed the alleged loss of consumer and investment interest in part to Gogo’s existing 

market power and to concerns about SmartSky’s own 

Case: 23-1058 Document: 63 Page: 11 Filed: 01/31/2024
12 SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC

product. J.A. 9617–19; J.A. 9569–71. On the other hand, 

as the district court noted, Gogo presented evidence that 

SmartSky continued to secure investments and customers 

even after Gogo announced its 5G network. J.A. 4762, 

4774; see also J.A. 21. Being able to secure customers and 

investors while facing a competing, allegedly infringing 

product “does not automatically rebut a case for irreparable injury.” Douglas Dynamics, LLC v. Buyers Prods. Co., 

717 F.3d 1336, 1344 (Fed. Cir. 2013). But such evidence is 

still relevant. Thus, we decline to find the district court 

abused its discretion by rejecting SmartSky’s reputation 

and goodwill argument as speculative. 

iv. 

SmartSky further contends that the district court erred 

in finding that SmartSky did not demonstrate irreparable 

harm based on past and future lost R&D and investments. 

Appellant’s Br. 57–58. Here too, we disagree. 

The district court found that “SmartSky’s assertion[]

that it stands to lose . . . its ability to recoup its R&D investments . . . is speculative,” J.A. 21, and we see no error

in this analysis. As for future opportunities, as the district 

court explained, a claim of lost opportunity to conduct future research alone is insufficient to compel a finding of irreparable harm. See Eli Lilly & Co. v. Am. Cyanamid Co., 

82 F.3d 1568, 1578 (Fed. Cir. 1996); J.A. 20–21. 

SmartSky instead challenges the district court’s decision by analogizing this case to Douglas Dynamics and 

TEK Global, S.R.L. v. Sealant Systems International, Inc. 

Appellant’s Br. 57–58 (first citing 717 F.3d at 1344–45; and 

then citing 920 F.3d 777, 792 (Fed. Cir. 2019)). But neither 

case is analogous. In Douglas Dynamics, it was the patentee’s reputation loss and role in creating the niche market as a result of its investments that led to our conclusion 

that remedies at law were inadequate, not the investments

themselves. 717 F.3d at 1344–45. And TEK does not address past or future R&D and investment losses. 920 F.3d 

Case: 23-1058 Document: 63 Page: 12 Filed: 01/31/2024
SMARTSKY NETWORKS, LLC v. GOGO BUSINESS AVIATION, LLC 13

at 792. Therefore, we reject SmartSky’s argument that the 

district court erred by not finding lost R&D and investments to be irreparable. 

v. 

SmartSky finally argues that the district court abused 

its discretion in finding that SmartSky did not show a likelihood of irreparable harm, despite the existence of “hallmark examples of irreparable harm,” including, for 

example, that SmartSky and Gogo are direct competitors, 

that the consumers are “sticky,” and that the competition 

from the allegedly infringing product concerns SmartSky’s 

flagship product and is “game-changing.” Appellant’s Br. 

42–45, 51–52. We are not persuaded. 

SmartSky relies on cases that are readily distinguishable from the present case. See Appellant’s Br. 47–49, 51 

(citing cases); see also Apple Inc. v. Samsung Elecs. Co., 809 

F.3d 633, 643 (Fed. Cir. 2015) (“Apple II”) (noting that

strength and weight of evidence is to be determined on a 

case-by-case basis). For example, in Douglas Dynamics, 

this court found that the district court erred in relying on 

evidence that the patentee and infringer targeted different 

consumers, while ignoring other evidence of irreparable 

harm including price erosion and lost market share. Id. at 

1344–45; see also Apple I, 735 F.3d at 1362 (distinguishing 

Douglas Dynamics for similar reasons). Here, the district 

court did not fail to properly address SmartSky’s evidence 

of price erosion and lost market share. Similarly, in Robert 

Bosch, this court held that the district court wrongly relied 

on the absence of a “two-player market,” “the non-core nature” of patentee’s impacted product, and the patentee’s 

“alleged failure to define a relevant market,” and failed to 

properly address evidence that the alleged infringer secured a former customer of the patentee in a market where 

a single customer accounts for a substantial portion of the 

entire customer base. 659 F.3d at 1152–54. Similar evidence of the loss of a few important customers is not

present in this case. Moreover, in Trebro Manufacturing 

Inc. v. Firefly Equipment LLC, the patentee presented “uncontroverted testimony” that the “market at issue in this 

case is a tiny market with only three players,” and because 

only roughly eight units of products are sold per year, “a 

single lost sale is a sizeable percentage of the yearly market in this area” and is a loss that the patentee is “not likely 

to recover”—evidence that is again absent here. 748 F.3d 

1159, 1170–71 (Fed. Cir. 2014). Lastly, in Apple II, this 

court vacated the district court’s order denying an injunction in part because of the district court’s erroneously narrow nexus analysis as a basis for not finding irreparable 

harm. 809 F.3d at 640–41, 647. Considering the case-bycase analysis and the distinct factual circumstances here, 

we are not persuaded by SmartSky’s “hallmark examples” 

argument. 

In summary, we conclude that the district court did not 

abuse its discretion in finding that SmartSky has failed to 

satisfy its burden to establish a likelihood of irreparable 

harm. 

IV. CONCLUSION

We have considered SmartSky’s remaining arguments 

and find them unpersuasive. For these reasons, we affirm

the district court’s denial of SmartSky’s motion for preliminary injunction. 

AFFIRMED
