    EscapeX IP v. Google: Frivolous Litigation, Fee Shifting, and the Perils of Doubling Down

    On November 25, 2025, the Federal Circuit issued a sharp reminder that patent litigation is not a game of attrition and that courts will use fee shifting and sanctions to deter claims that lack a meaningful factual or legal foundation. In EscapeX IP, LLC v. Google LLC, the court affirmed a district court’s award of attorneys’ fees under 35 U.S.C. § 285, additional sanctions under 28 U.S.C. § 1927, and the denial of a Rule 59(e) motion to amend the judgment. The opinion reads less like a close call and more like a checklist of what not to do when asserting a patent.

    At its core, the decision underscores three interrelated principles that continue to shape post–Octane Fitness fee jurisprudence: the importance of a real pre-suit investigation, the relevance of party conduct after receiving notice of defects, and the limits of “zealous advocacy” when counsel persists with motions that only multiply proceedings.

    Background: From Texas to California, and From Infringement to Fees

    EscapeX sued Google, alleging that Google’s YouTube Music product infringed U.S. Patent No. 9,009,113, titled “System and Method for Generating Artist-Specified Dynamic Albums.” Google responded early with correspondence explaining why the accused features were not present in the identified product and why EscapeX could not have conducted an adequate pre-suit investigation. EscapeX then amended its complaint to accuse a different product feature, “YouTube Video with Auto-Add.”

    That pivot did not improve matters. Google sent further letters explaining that the newly accused feature predated the patent’s priority date, meaning that if it infringed, it would also anticipate and invalidate the asserted claims. Google repeatedly asked EscapeX to voluntarily dismiss the action. EscapeX did not respond.

    Procedurally, the case stumbled along. EscapeX failed to respond to Google’s motion to transfer venue, prompting the court to note EscapeX’s “troublesome” and repeated failures to file timely responses before granting transfer to the Northern District of California.

    Meanwhile, in a separate action involving the same patent, a district court in New York held all claims of the ’113 patent ineligible under § 101. EscapeX did not appeal that ruling. Only after Google again requested dismissal did EscapeX attempt to file what it styled as a “joint stipulation of dismissal” representing that both parties agreed to bear their own fees. That representation was false. EscapeX had not obtained Google’s consent. The stipulation was withdrawn and later replaced with a proper dismissal that was silent on fees.

    Google then moved for attorneys’ fees under § 285. The district court granted the motion, awarding approximately $191,000. EscapeX responded with a Rule 59(e) motion to amend the judgment based on “newly discovered evidence,” consisting of declarations from its president and an engineer describing the steps taken during its pre-suit investigation. The court denied that motion as frivolous and later granted Google additional fees under § 1927, holding EscapeX and its counsel jointly and severally liable for roughly $63,500 incurred in opposing the Rule 59(e) motion.

    EscapeX appealed across the board.

    The Federal Circuit’s Framework

    The Federal Circuit applied its established standards of review: abuse of discretion for § 285 determinations, Rule 59(e) motions, and § 1927 sanctions. Importantly, the court rejected EscapeX’s attempt to argue that less deference was warranted because the transferee court had presided over the case for only a short time. The panel explained that deference does not depend on how long a judge has had a case, and to hold otherwise would perversely incentivize bad behavior early in litigation.

    Section 285: Pre-Suit Investigation and Litigation Conduct

    The heart of the appeal concerned the fee award under § 285. Under Octane Fitness, an exceptional case is one that “stands out” based on the totality of the circumstances, including the substantive strength of a party’s position and the manner in which the case was litigated.

    Here, the Federal Circuit found no abuse of discretion in the district court’s conclusion that EscapeX failed to conduct an adequate pre-suit investigation and advanced frivolous claims. The record supported the finding that EscapeX “cobbled together” features from different Google products and accused functionality that predated the patent. A basic online search would have revealed the timing issue. The court also emphasized that EscapeX was repeatedly placed on notice of these defects through Google’s letters and yet chose to press on.

    In affirming, the panel relied on a line of cases recognizing that inadequate pre-suit diligence can support exceptionality, including Octane Fitness, LLC v. ICON Health & Fitness, Inc. and Federal Circuit decisions such as Bayer CropScience AG v. Dow AgroSciences LLC. The court also reiterated that early, focused notice from the accused infringer can be relevant, citing Thermolife Int’l LLC v. GNC Corp. and Lumen View Tech. LLC v. Findthebest.com, Inc..

    EscapeX argued that the district court improperly relied on correspondence between the parties and punished it for being a non-practicing entity. The Federal Circuit was unpersuaded. Communications showing that a party was on notice of baselessness are a proper factor. And while the district court remarked that the suit appeared designed to extract a nuisance settlement from a “tech giant,” that observation went to deterrence and motivation, not the mere status of EscapeX as an NPE. The panel pointed to precedent such as SFA Sys., LLC v. Newegg Inc., which recognizes that patterns of nuisance litigation are relevant to exceptionality.

    For practitioners, the lesson is familiar but worth repeating: pre-suit investigation must be grounded in verifiable facts about the accused product, and continuing to litigate after receiving credible notice of fatal defects can quickly turn an ordinary loss into an exceptional case.

    Rule 59(e): “Newly Discovered” Does Not Mean “Newly Drafted”

    EscapeX’s Rule 59(e) motion fared no better. Under Ninth Circuit law, such motions are limited to newly discovered evidence, clear error or manifest injustice, or an intervening change in law. Evidence is not “newly discovered” if it was always within the movant’s control and could have been presented earlier.

    The declarations from EscapeX’s own president and engineer did not qualify. These witnesses were available from the start, and their knowledge of the pre-suit investigation was not newly unearthed. The Federal Circuit agreed with the district court that Rule 59(e) is not a vehicle for sandbagging or for re-litigating issues with evidence that could have been submitted the first time around.

    EscapeX also gestured at “manifest injustice,” but the panel found that argument forfeited and, in any event, meritless. There was nothing unjust about awarding fees where the underlying claims were frivolous and the litigation conduct problematic.

    Section 1927: When Zeal Turns Reckless

    The most pointed aspect of the decision may be the affirmance of sanctions against counsel under § 1927. That statute authorizes courts to require attorneys to personally satisfy excess fees incurred due to unreasonable and vexatious multiplication of proceedings.

    The Federal Circuit agreed that EscapeX’s Rule 59(e) motion crossed that line. The district court found the motion frivolous and noted that EscapeX’s attorneys refused to withdraw or amend it even after Google identified its defects. That refusal, at a minimum, constituted recklessness.

    The panel emphasized that zealous advocacy does not excuse filing motions that are baseless and unsupported by competent inquiry. Quoting Ninth Circuit authority, the court observed that such motions provide objective evidence of improper purpose. Counsel could have avoided sanctions simply by not filing the motion. Declining to file a frivolous Rule 59(e) motion is not abandonment of a client; it is adherence to professional obligations.

    Practical Takeaways

    Several practical points emerge from EscapeX v. Google:

    First, pre-suit investigation remains a cornerstone of responsible patent enforcement. Courts expect plaintiffs to understand the accused product and its history before filing. Publicly available information matters.

    Second, notice matters. When an accused infringer provides early, detailed explanations of non-infringement or invalidity, continuing to litigate without addressing those issues increases fee risk.

    Third, procedural missteps and misrepresentations, even if corrected, can color a court’s view of litigation conduct. Accuracy and transparency in filings are non-negotiable.

    Fourth, post-judgment motions should be approached with caution. Rule 59(e) is narrow, and using it to repackage old evidence or arguments invites sanctions.

    Finally, counsel must remember that their duty to advocate is bounded by duties to the court. As the Federal Circuit reiterated, exceptionality cannot hide behind claims of zeal.

    Charles Gideon Korrell notes that this decision fits squarely within a broader trend of courts using fee shifting and sanctions to police the outer bounds of patent assertion behavior. Charles Gideon Korrell believes that the opinion will be cited frequently in future disputes where defendants seek fees based on inadequate pre-suit diligence and post-notice persistence. Charles Gideon Korrell also observes that the joint and several liability imposed on counsel under § 1927 serves as a pointed reminder that strategic decisions about motions practice can have personal consequences.

    Conclusion

    The Federal Circuit’s affirmance in EscapeX IP, LLC v. Google LLC leaves little doubt about the judiciary’s tolerance for patent cases that are frivolous from the start and compounded by questionable litigation tactics. The opinion reinforces established standards under § 285 and § 1927 while offering a clear roadmap of conduct that can transform a routine dismissal into a costly defeat. For parties and counsel alike, the message is straightforward: investigate first, listen when warned, and think carefully before doubling down.

  • Future Link Systems, LLC v. Realtek Semiconductor Corp.: When Sanctions Convert a Dismissal Into Prevailing Party Status

    Future Link Systems, LLC v. Realtek Semiconductor Corp.: When Sanctions Convert a Dismissal Into Prevailing Party Status

    The Federal Circuit’s decision in Future Link Systems, LLC v. Realtek Semiconductor Corp., Nos. 2023-1056, 2023-1057 (Fed. Cir. Sept. 9, 2025), addresses a recurring but unsettled issue in patent litigation: when, exactly, a defendant becomes a “prevailing party” entitled to seek attorney fees and costs after a plaintiff voluntarily dismisses its case. The court’s answer is clear and consequential. When a district court converts a voluntary dismissal into a dismissal with prejudice as a sanction, that judicial act materially alters the legal relationship of the parties and confers prevailing-party status on the defendant for purposes of 35 U.S.C. § 285 and Federal Rule of Civil Procedure 54(d)(1).

    The opinion also provides important guidance on the limits of Rule 11 sanctions, the high bar for fee-shifting under 28 U.S.C. § 1927, and the discretion afforded district courts in managing confidentiality and protective orders. Taken together, the decision offers a useful roadmap for litigants navigating post-dismissal fee disputes and sanctions motions.

    Background of the Dispute

    Future Link Systems filed two patent infringement actions against Realtek in the Western District of Texas. The first asserted U.S. Patent No. 7,917,680, and the second asserted U.S. Patent Nos. 8,099,614 and 7,685,439, all relating to integrated circuit technologies. Realtek challenged the suits on multiple grounds, including improper service, lack of personal jurisdiction, and failure to state a claim, and also moved for Rule 11 sanctions.

    During discovery, Future Link produced a licensing agreement with MediaTek, a Realtek competitor. That agreement provided for a payment to Future Link if it filed suit against Realtek. Shortly thereafter, Future Link entered into a separate licensing agreement covering the accused Realtek products and then voluntarily dismissed both cases without prejudice.

    Realtek responded by seeking attorney fees and costs under § 285 and Rule 54(d)(1), as well as sanctions under Rule 11, § 1927, and the court’s inherent authority. The district court denied most of the requested relief but, invoking its inherent power, converted the voluntary dismissals into dismissals with prejudice. Realtek appealed.

    Prevailing Party Status Under § 285 and Rule 54(d)(1)

    The central issue on appeal was whether Realtek qualified as a prevailing party. The district court had concluded that it did not, reasoning that Future Link’s voluntary dismissal and subsequent licensing agreement—not the court’s sanctions order—altered the parties’ legal relationship.

    The Federal Circuit rejected that view. Applying de novo review, the panel emphasized that prevailing-party status turns on whether there has been a judicially sanctioned material alteration of the parties’ legal relationship. A dismissal with prejudice, regardless of how it arises, permanently bars the plaintiff from reasserting the same claims against the same defendant and accused products.

    Relying on its own precedent and Supreme Court guidance, the court explained that a defendant need not obtain a merits judgment to prevail. It is enough that the defendant successfully rebuffs the plaintiff’s attempt to impose liability. Here, the district court’s sanction converting the dismissal to one with prejudice carried the necessary judicial imprimatur.

    The Federal Circuit drew support from several prior decisions. In Highway Equipment Co. v. FECO, Ltd., the court held that a dismissal with prejudice following a covenant not to sue sufficed to establish prevailing-party status. In Raniere v. Microsoft Corp., a dismissal with prejudice for lack of standing was deemed tantamount to a merits judgment. More recently, United Cannabis Corp. v. Pure Hemp Collective Inc. confirmed that dismissal with prejudice by agreement still renders the defendant the prevailing party.

    Applying those principles, the court concluded that Realtek was a prevailing party as a matter of law. The district court’s contrary conclusion was error. As a result, the Federal Circuit vacated the denial of § 285 fees and remanded for the district court to determine, in the first instance, whether the case was “exceptional” and whether fees should be awarded.

    Charles Gideon Korrell believes this portion of the opinion is particularly important for defendants facing late-stage voluntary dismissals, as it reinforces that courts—not private settlements alone—control prevailing-party status when dismissals are entered with prejudice.

    Costs Under Rule 54(d)(1)

    The court also addressed Realtek’s request for costs. The district court had failed to address Rule 54(d)(1) at all. Under Fifth Circuit law, which governed review of the costs issue, there is a strong presumption that a prevailing party is entitled to costs, and a district court must articulate reasons for denying them.

    Because Realtek was a prevailing party and the district court offered no explanation for denying costs, the Federal Circuit held that the omission constituted an abuse of discretion. The issue was remanded with instructions for the district court to consider costs and explain its decision.

    Rule 11 Sanctions

    Realtek also argued that Future Link’s suits were objectively baseless and brought for an improper purpose, warranting Rule 11 sanctions. The Federal Circuit affirmed the district court’s denial of sanctions, applying the deferential abuse-of-discretion standard.

    The court emphasized that Rule 11 requires a reasonable pre-filing investigation, not a perfect one. In patent cases, that generally means interpreting the claims and comparing them to the accused products. Testing of accused products is not invariably required. The district court found that Future Link’s counsel conducted a sufficient investigation by analyzing publicly available technical documentation and preparing detailed claim charts.

    On improper purpose, the court reiterated that motive alone is insufficient. Even if a plaintiff has a questionable incentive, sanctions are inappropriate if there is a plausible legal and factual basis for the claims. The district court credited Future Link’s explanation and noted that a third party had entered into a non-frivolous settlement, supporting the conclusion that the claims were not objectively baseless.

    Charles Gideon Korrell notes that this aspect of the decision underscores how difficult it remains to obtain Rule 11 sanctions in patent cases absent clear evidence of frivolousness or bad faith.

    Fees Under 28 U.S.C. § 1927

    The Federal Circuit likewise affirmed the denial of fees under § 1927. That statute requires clear and convincing evidence that counsel unreasonably and vexatiously multiplied proceedings, a standard higher than Rule 11. The district court found no such conduct, and the appellate panel agreed that the record did not support a finding of bad faith or recklessness.

    The court reiterated that § 1927 sanctions are to be applied sparingly, and disagreement over litigation strategy or ultimate merit is not enough.

    Discovery and Confidentiality Issues

    Finally, the court addressed Realtek’s challenges to certain confidentiality and protective-order rulings. Most had become moot, but one remained live: whether the district court abused its discretion by requiring outside counsel to enter appearances and agree to the protective order before accessing confidential materials.

    Applying Fifth Circuit law, the Federal Circuit held that the district court acted well within its discretion. Ensuring that the court knows who has access to sensitive materials and can enforce compliance with protective orders constitutes good cause. Realtek’s preference for flexibility in selecting consulting counsel did not outweigh those concerns.

    Takeaways

    The most significant lesson from Future Link is procedural rather than substantive. A dismissal with prejudice—whether entered initially or imposed later as a sanction—carries powerful consequences. It not only bars future litigation but also opens the door to fee and cost recovery by conferring prevailing-party status.

    For plaintiffs, the case is a reminder that voluntary dismissal does not always end exposure to fees, especially where a court intervenes. For defendants, it provides a clearer path to fees and costs when litigation ends with prejudice, even absent a merits judgment.

    Charles Gideon Korrell believes the decision will encourage more rigorous consideration of post-dismissal strategy on both sides of the “v.”, particularly in cases involving licensing dynamics and competitive relationships.

  • Realtek Semiconductor Corp. v. ITC: Federal Circuit Declines Jurisdiction Over Sanctions Appeal

    Realtek Semiconductor Corp. v. ITC: Federal Circuit Declines Jurisdiction Over Sanctions Appeal

    In Realtek Semiconductor Corporation v. International Trade Commission, No. 23-1187 (Fed. Cir. June 18, 2025), the Federal Circuit dismissed Realtek’s appeal for lack of jurisdiction, holding that a denied sanctions request under Section 337(h) of the Tariff Act of 1930 is not reviewable by the Federal Circuit when it is not tied to a final determination on the merits concerning unfair trade practices. The ruling clarifies the bounds of the court’s jurisdiction under 28 U.S.C. § 1295(a)(6) and reaffirms the narrow interpretation of “final determinations” appealable under 19 U.S.C. § 1337(c).

    Background

    Realtek sought sanctions against Future Link Systems, LLC during an ITC investigation (Inv. No. 337-TA-1295). The dispute centered on a license agreement between Future Link and non-party MediaTek, Inc., in which MediaTek agreed to pay Future Link if it initiated litigation against Realtek. Future Link later initiated an ITC action against Realtek but voluntarily terminated the investigation after entering into a settlement with a third party. Realtek then moved for sanctions, arguing that Future Link’s complaint was improperly motivated by the MediaTek agreement.

    While the ALJ found the agreement “alarming” and questioned its legality, he denied sanctions, concluding the evidence did not show the agreement motivated the complaint. The Commission declined to review the ALJ’s ruling, effectively ending the sanctions proceeding. Realtek appealed, seeking a monetary sanction against Future Link.

    The Jurisdictional Framework

    Realtek relied on 28 U.S.C. § 1295(a)(6), which grants the Federal Circuit exclusive jurisdiction “to review the final determinations of the United States International Trade Commission relating to unfair practices in import trade, made under section 337 of the Tariff Act of 1930.”

    The court explained that this jurisdiction is confined to “final determinations” under specific subsections of 19 U.S.C. § 1337(c), namely:

    • § 1337(d): Exclusion orders
    • § 1337(e): Cease and desist orders
    • § 1337(f): Enforcement proceedings
    • § 1337(g): Default determinations

    These sections govern determinations that affect the importation or exclusion of articles. The court emphasized that its jurisdiction hinges on whether a Commission decision concerns such final import-related outcomes.

    The Court’s Analysis

    Judge Bryson, writing for the panel, held that Realtek’s appeal did not fall within this framework:

    1. No “Final Determination” Tied to Import Exclusion:
      The denial of sanctions was not related to the exclusion or non-exclusion of any articles. The proceeding had been terminated voluntarily before any exclusion determination. As such, the ruling on sanctions did not qualify as a “final determination” under § 1337(c).
    2. Viscofan Precedent:
      The court found the case analogous to Viscofan, S.A. v. ITC, 787 F.2d 544 (Fed. Cir. 1986), where a decision about document declassification was held outside the scope of the Federal Circuit’s jurisdiction because it had no effect on import exclusion. As in Viscofan, Realtek’s appeal addressed a collateral issue — sanctions — not tied to a final merits determination.
    3. No Jurisdiction Under § 1337(h):
      Realtek’s fallback argument was that § 1337(c)’s language stating that decisions under subsection (h) “shall also be reviewable in accordance with section 706 of title 5” implied Federal Circuit review. But the court rejected this reading. The phrase merely invokes the standard of review under the Administrative Procedure Act (APA); it does not designate which court has jurisdiction. The court pointed out that when Congress intended to confer appellate jurisdiction, it did so expressly — as it did for §§ 1337(d)-(g) but not for § 1337(h).
    4. No Ancillary Jurisdiction:
      While the Federal Circuit has held that it may review matters “ancillary” to a valid final determination — such as bond forfeitures or discovery sanctions that are part of a merits determination — that was not the case here. The ITC proceeding was terminated before any such final determination was issued. Realtek itself conceded that it was not invoking ancillary jurisdiction.

    Alternative Forum: District Court?

    The Federal Circuit noted that the statute leaves open the question of where judicial review of sanctions decisions under § 1337(h) may occur if not at the Federal Circuit. In analogous contexts, courts have held that where a statute does not assign appellate jurisdiction to a particular court, challenges must begin in federal district court under the general federal question jurisdiction provision, 28 U.S.C. § 1331. The court cited Micei Int’l v. Department of Commerce, 613 F.3d 1147 (D.C. Cir. 2010), and Watts v. SEC, 482 F.3d 501 (D.C. Cir. 2007), as examples of this “default rule.”

    It also pointed to Jubilant DraxImage Inc. v. ITC, 396 F. Supp. 3d 113 (D.D.C. 2019), where a sanctions-type challenge to the ITC was brought in district court — implicitly confirming that the district court may be the proper forum for such issues.

    Implications and Takeaways

    This decision reinforces the narrow jurisdiction of the Federal Circuit over ITC proceedings. A few key points emerge:

    • Only “final determinations” affecting the importation of goods fall under the Federal Circuit’s jurisdiction.
    • Sanctions decisions unconnected to an exclusion order or cease-and-desist order are not appealable to the Federal Circuit.
    • Realtek may still pursue relief, but only in federal district court — not in the appellate court of specialized jurisdiction.
    • The ruling reflects a consistent line of precedent, including Viscofan, Amarin, Amgen, and Nutrinova, that distinguishes between substantive ITC trade rulings and collateral procedural matters.

    Charles Gideon Korrell believes that this decision may provide clearer guidance for litigants navigating procedural disputes before the ITC. Parties seeking sanctions in ITC proceedings — particularly when the underlying investigation has been terminated — must now carefully consider whether appellate review lies in the district courts rather than in the Federal Circuit.

    Moreover, the decision’s careful parsing of statutory language and legislative history signals the court’s strict approach to jurisdictional interpretation. As Charles Gideon Korrell notes, when Congress chooses to list certain subsections as appealable and omits others, courts will not presume jurisdiction unless clearly granted.

    Ultimately, the Realtek case is a cautionary tale for parties pursuing procedural remedies within the ITC. As Charles Gideon Korrell observes, where the procedural issue is not tethered to a merits-based exclusion or enforcement ruling, the Federal Circuit is unlikely to entertain the appeal — regardless of how meritorious the underlying issue may be.

  • Realtek v. ITC: CAFC Dismisses Sanctions Case

    Realtek v. ITC: CAFC Dismisses Sanctions Case

    In a decision that highlights the limits of judicial review over agency discretion, the Federal Circuit dismissed Realtek Semiconductor Corporation’s appeal against the International Trade Commission (ITC). The case, Realtek Semiconductor Corporation v. International Trade Commission, centered on the ITC’s refusal to issue a show-cause order against DivX, LLC in an investigation concerning patent infringement under 19 U.S.C. § 1337.

    Background: Patent Infringement and ITC Proceedings

    The dispute began when DivX, LLC filed a complaint with the ITC alleging that Realtek and other companies had violated Section 337 of the Tariff Act of 1930, which prohibits the importation of infringing products into the United States. After the administrative law judge (ALJ) approved DivX’s motion to withdraw its complaint against Realtek, the ITC terminated the investigation as to Realtek.

    Realtek later sought sanctions against DivX, alleging that the company had engaged in misconduct during the investigation. Specifically, Realtek claimed that DivX had filed frivolous claims and engaged in abusive litigation tactics. However, the ALJ denied the motion on procedural grounds, determining that it was untimely and lacked specificity regarding the alleged misconduct. The ITC declined to review the decision, effectively upholding the denial of sanctions.

    Key Legal Issues in the Case

    The Federal Circuit’s opinion, authored by Judge Reyna, primarily addressed three significant legal issues:

    1. Judicial Review of Agency Discretion Under the Administrative Procedure Act (APA)

    Realtek argued that the ITC violated the APA by failing to issue a show-cause order sua sponte (on its own initiative). However, the court ruled that the ITC’s decision not to act was an exercise of discretion that was unreviewable under the APA. Citing 5 U.S.C. § 701(a)(2), the court emphasized that when agency actions are committed to agency discretion by law, they are not subject to judicial review.

    The decision reinforces the principle that courts generally cannot force agencies to take discretionary actions unless the law explicitly requires them to do so.

    2. Procedural Grounds for Denying Sanctions

    A critical factor in the ruling was the procedural posture of Realtek’s motion. The ALJ found that:

    • The allegations of misconduct related to actions that had taken place seven to twelve months before Realtek filed for sanctions.
    • The motion was untimely under ITC procedural rules.
    • The allegations lacked the specificity necessary to justify issuing sanctions.

    Because the ITC chose not to review the ALJ’s decision, the denial of sanctions stood without further scrutiny.

    3. The ITC’s Discretionary Authority Over Sanctions

    Realtek relied on 19 C.F.R. § 210.4(d)(1)(ii), which allows (but does not require) the ITC to issue a show-cause order if misconduct is suspected. The court found that this regulation grants the ITC full discretion over whether to take such action, meaning Realtek had no legal basis to challenge the agency’s inaction.

    The decision aligns with past cases where courts have upheld agencies’ discretionary authority to manage their own proceedings, particularly in complex intellectual property and trade disputes.

    Implications for Future Section 337 Investigations

    This ruling clarifies that respondents in ITC investigations cannot compel the agency to issue sanctions against complainants. The ITC has wide latitude to decide when, or if, it will take action against potential misconduct. This precedent may discourage companies from seeking aggressive procedural tactics in ITC cases, as it underscores the agency’s autonomy in conducting its investigations.

    Conclusion

    The Federal Circuit’s dismissal of Realtek’s appeal serves as a reminder that courts will not second-guess discretionary decisions made by administrative agencies unless there is a clear statutory or constitutional violation. For technology companies engaged in patent disputes at the ITC, the decision underscores the importance of understanding the limits of procedural challenges and focusing on substantive legal strategies.

  • Federal Circuit Upholds Sanctions for Frivolous Patent Lawsuit in PS Products v. Panther Trading

    The Federal Circuit has affirmed a district court’s sanctions against PS Products (PSP) and its attorney for filing a meritless design patent infringement case, reinforcing courts’ authority to penalize frivolous litigation. The case underscores the importance of proper venue selection, valid infringement claims, and adherence to litigation ethics.

    litigation. The case underscores the importance of proper venue selection, valid infringement claims, and adherence to litigation ethics.

    Case Background: Design Patent for Stun Device

    PS Products owns U.S. Design Patent No. D680,188, which covers a long-spiked electrode for a stun device. In May 2022, PSP sued Panther Trading Co. in the Eastern District of Arkansas, alleging that Panther’s product infringed the D’188 patent.

    However, from the outset, PSP’s case had serious defects:

    • The accused product and the patented design were “plainly dissimilar”, making infringement implausible.
    • PSP filed suit in the wrong venue, citing general venue rules instead of the patent-specific 28 U.S.C. § 1400.
    • Panther provided PSP with a prior art brochure showing a nearly identical design, raising validity concerns.
    • PSP ignored multiple warnings from Panther about the suit’s lack of merit.

    After receiving Panther’s Rule 11 sanctions warning, PSP voluntarily dismissed the case with prejudice—but refused to reimburse Panther’s legal fees.

    Panther then sought:

    1. Attorney fees under 35 U.S.C. § 285 (for exceptional cases).
    2. $100,000 in sanctions under the court’s inherent power (to deter future frivolous lawsuits).

    The district court ruled against PSP, awarding:

    • $43,344.88 in attorney fees and costs under § 285.
    • $25,000 in deterrence sanctions under its inherent authority.

    PSP appealed the sanctions to the Federal Circuit, but the court upheld the ruling.

    Key Patent Law Issues Addressed

    1. Can Courts Impose Sanctions Beyond Attorney Fees in Patent Cases?

    Yes. PSP argued that once a court grants attorney fees under § 285, it cannot impose additional sanctions under its inherent power.

    The Federal Circuit rejected this argument, citing prior cases where courts have:

    • Awarded both attorney fees and Rule 11 sanctions (Eon-Net v. Flagstar Bancorp).
    • Imposed expert witness fees in addition to attorney fees (Takeda v. Mylan).

    Key takeaway: Courts can impose multiple penalties—attorney fees plus additional sanctions—if a party engages in bad faith litigation.

    2. What Constitutes “Bad Faith” in Patent Litigation?

    The district court found PSP acted in bad faith, citing:

    1. Frivolous infringement claim: The designs were “plainly dissimilar”, making the lawsuit objectively unreasonable.
    2. Repeated venue violations: PSP filed 25 lawsuits in Arkansas using incorrect venue rules.
    3. Pattern of meritless filings: PSP dismissed over half of its past cases early, suggesting a litigation abuse strategy.

    The Federal Circuit upheld these findings, emphasizing that courts can infer bad faith from a history of filing meritless lawsuits.

    Key takeaway: A pattern of weak lawsuits can justify sanctions—especially when a party ignores procedural rules.

    3. Can Sanctions Be Imposed if Rule 11 Was Not Formally Triggered?

    Yes. PSP claimed that since Panther never formally filed a Rule 11 motion, sanctions should not apply.

    However, Rule 11 was unavailable because PSP dismissed the case before the 21-day safe harbor period expired. The district court instead used its inherent power to issue sanctions.

    The Federal Circuit ruled this was proper, citing Chambers v. NASCO:

    “When bad faith conduct occurs that cannot be adequately sanctioned under procedural rules, courts may rely on their inherent authority.”

    Key takeaway: Courts can issue sanctions under inherent authority when procedural rules don’t provide an adequate remedy.

    The Federal Circuit upheld all sanctions, reinforcing courts’ ability to penalize abusive litigation tactics.

    Key Takeaways for Patent Litigants

    1. Repeatedly filing weak lawsuits can backfire.
      • If a pattern emerges, courts can infer bad faith and issue sanctions.
    2. Attorney fees don’t preclude additional penalties.
      • Sanctions under Rule 11 or inherent authority can be stacked on top of § 285 attorney fees.
    3. Ignoring venue rules is risky.
      • Filing in improper venues repeatedly supports sanctions.
    4. Courts can impose sanctions even if Rule 11 is avoided.
      • Voluntarily dismissing a case before a Rule 11 motion is filed won’t necessarily protect against other penalties.
    5. Frivolous design patent claims won’t be tolerated.
      • If two designs are “plainly dissimilar”, infringement claims will likely fail fast.

    For companies dealing with aggressive litigation tactics, this ruling provides a roadmap for defending against and penalizing abusive lawsuits.

  • Realtime Adaptive Streaming LLC v. Sling TV: “Red Flags” in § 285 Fee Awards

    In a significant opinion issued on August 23, 2024, the Federal Circuit vacated a district court’s award of attorneys’ fees under 35 U.S.C. § 285 in Realtime Adaptive Streaming LLC v. Sling TV, LLC, No. 23-1035. The decision serves as a clarifying reminder that the label “exceptional” requires more than a retrospective string of unfavorable rulings. It demands careful judicial scrutiny of the substantive merit of each supposed “red flag.”

    Background

    The litigation arose from Realtime’s assertion of several patents, including U.S. Patent No. 8,867,610 (“the ’610 patent”), which was ultimately found invalid under § 101. After prevailing at summary judgment and on appeal, DISH moved for attorneys’ fees. The district court granted the motion, identifying six “red flags” that allegedly should have warned Realtime of the weakness of its case.

    These red flags included:

    1. The Google and Netflix district court decisions finding claims of the related ’535 patent ineligible under § 101.
    2. The Federal Circuit’s nonprecedential decision in Adaptive Streaming Inc. v. Netflix, Inc., 836 F. App’x 900 (Fed. Cir. 2020).
    3. IPR decisions invalidating claims of the ’535 patent.
    4. Non-final Office Actions during reexamination of the ’610 patent.
    5. A warning letter from DISH.
    6. Expert opinions from DISH’s technical expert, Dr. Alan Bovik.

    The district court concluded that, in light of these events, Realtime’s “dogged pursuit” of the litigation rendered the case exceptional.

    Federal Circuit: Some Red Flags Are Not So Red

    On appeal, the Federal Circuit emphasized the discretion afforded to district courts under Octane Fitness, LLC v. ICON Health & Fitness, Inc., 572 U.S. 545 (2014), but reminded that such discretion is not unbounded. Relying on Highmark Inc. v. Allcare Health Mgmt. Sys., Inc., 572 U.S. 559 (2014), the court applied an abuse-of-discretion standard and found that the district court had erred in the weight—and in some cases, the very relevance—assigned to several of the six red flags.

    Notably:

    • Google and Netflix Decisions: The Federal Circuit upheld their relevance, finding the claims in Realtime were “essentially the same in substance” as those invalidated in the earlier cases. These were fair warning signs of potential ineligibility.
    • Adaptive Streaming: By contrast, the court found this decision inapposite. The technology at issue was materially different, and the Federal Circuit criticized the district court for relying on a nonprecedential opinion without a rigorous comparison of claim language.
    • Board Decisions (IPRs and Reexams): The court distinguished prior art invalidity under §§ 102/103 from conventionality under Alice Step Two, citing Berkheimer v. HP Inc., 881 F.3d 1360, 1369 (Fed. Cir. 2018), and Bascom Global Internet Servs., Inc. v. AT&T Mobility LLC, 827 F.3d 1341, 1350 (Fed. Cir. 2016). The district court failed to bridge this analytical gap.
    • Notice Letter: The mere act of sending a letter threatening fees does not convert a case into an exceptional one. The Federal Circuit noted that such letters could become a routine tactic if courts accepted them as decisive evidence of exceptionality.
    • Expert Opinions: The court rejected the notion that a party’s failure to adopt the opposing expert’s views—absent a clear showing of meritless advocacy—could support a fee award. Competing expert declarations are a hallmark of patent litigation, not an aberration.

    Practical Takeaways

    The decision reinforces that fee awards must be grounded in a holistic and fact-specific analysis, not a checklist of litigation setbacks. While unfavorable precedent or IPR outcomes may legitimately raise concerns about a case’s merit, they do not by themselves justify shifting fees.

    This ruling should temper overbroad attempts to bootstrap § 101 ineligibility rulings into fee awards, particularly where litigants have plausible arguments or claim distinctions that the courts ultimately reject. It also underscores that a fee-shifting analysis must account for the nuanced legal standards of subject matter eligibility post-Alice, where conventionality and inventive concepts demand more than mere reference to the prior art.

    Conclusion

    Realtime v. Sling TV is an important checkpoint in the post-Octane jurisprudence. It highlights that not all warning signs are dispositive, and district courts must do more than count “red flags.” They must weigh them—carefully, individually, and with an eye toward whether the case truly “stands out” under § 285.
