District Court Finding Doesn’t Preclude PTAB Proceeding

The Patent Trial & Appeal Board refused to terminate an inter partes review (IPR) proceeding, finding that collateral estoppel and claim preclusion do not apply to previous findings from a district court proceeding. Patent Quality Assurance, LLC v. VLSI Technology LLC, IPR2021-01229, Paper No. 128 (PTAB June 3, 2023) (Melvin, Giannetti, McNamara, APJs).

Patent Quality Assurance filed a petition for IPR on July 7, 2021, against a patent owned by VLSI. The Board granted institution. The Board later instituted on a substantively identical petition filed by Intel and granted Intel’s motion for joinder to add Intel to the Patent Quality Assurance IPR proceeding. Prior to the July 7, 2021, petition, litigation between VLSI and Intel resulted in a jury verdict that Intel infringed certain claims of the challenged patent. Invalidity was not presented to the jury. On May 10, 2022, the district court entered final judgment, including a finding that Intel had not proven invalidity. Based on the district court’s judgment, VLSI asserted that claim preclusion barred Intel from challenging validity of the asserted patent in IPR and sought termination of the IPR as to Intel.

VLSI argued that the elements of claim preclusion were met because both VLSI and Intel were parties to both cases, the district court entered a final judgment for infringement and no finding of invalidity, and the effect of Intel’s IPR was to collaterally attack the final judgment in the first case. Intel responded, arguing that claim preclusion does not apply to IPRs from the district court under the America Invents Act (AIA).

The Board agreed with Intel that estoppel did not apply. Intel argued that if Congress had intended for IPRs to be precluded by claims in a parallel district court, it would have identified that as one of the estoppel circumstances in the AIA. VLSI argued that the Supreme Court’s 1991 decision in Astoria Federal sav. & Loan Ass’n v. Solimino applies only when an agency decision precludes a later court decision and, therefore, common-law claim preclusion would apply to the IPR proceeding barring a plain statement from Congress showing intent to overcome preclusion.

The Board disagreed, noting that the cited case law related to statutes where a later statute superseded the earlier one and required a clear and manifest intent to repeal the earlier statute. The Board found that there was no express intent to repeal the earlier statute regarding estoppel, and the jurisprudence constantly counsels against repeal “by implication.” The Board also crucially noted that there was no statutory conflict between the earlier and later statutes, and the question, therefore, was whether (under Astoria) the AIA showed congressional intent that common-law claim preclusion should apply to IPRs.

Reading 35 U.S.C. § 315(e), the codification of the AIA’s estoppel provision, the Board noted that the statute clearly imposes estoppel on future agency and district proceedings but says nothing about applying adjudications in district court proceedings at the Board. As the Board explained, there would be no reason for § 315(e) to spell [...]

Obviously Prima Facie Case Overcome by Secondary Considerations

The US Court of Appeals for the Federal Circuit affirmed the Patent Trial & Appeal Board, holding that the Board did not err in finding certain challenged claims nonobvious and not unpatentable based on a showing of several objective criteria of nonobviousness and a nexus of the evidence to a commercial product embodying the claimed invention. Medtronic, Inc. v. Teleflex Innovations S.A.R.L., Case No. 21-2357 (Fed. Cir. June 05, 2023) (Moore, C.J.; Lourie, Dyk, JJ.) and Medtronic, Inc. v. Teleflex Innovations S.A.R.L., Case No. 21-2359 (Fed. Cir. June 05, 2023) (Moore, C.J.; Lourie, Dyk, JJ.)

Teleflex developed and patented a novel catheter-based stenosis intervention system that successfully mitigated long-standing risks intrinsic to existing catheter-based intervention systems, in particular damage to the coronary artery from guide catheter dislodgement or a catheter’s distal tip (i.e., the end of the catheter farthest from the insertion site). The preferred embodiments incorporated into Teleflex’s extremely successful GuideLiner products comprised a proximal substantially rigid portion (yellow), a reinforced portion (blue) and a distal flexible tip (pink), as illustrated below.

The catheters were sized so they could be inserted through standard guide catheters and thus were coined guide extension catheters. This innovative nesting feature increased guide catheter backup support while the guide extension catheter’s soft distal end was less likely to cause tissue damage once deeply inserted into patients. Teleflex’s guide extension catheters also were optimized for receiving interventional cardiological devices. This optimized function was a combination of the catheter’s coaxial lumen, that lumen’s diameter being no more than one French (i.e., 1/3 mm) less than the diameter of the guide catheter, and a proximal side opening that featured a double incline design like that illustrated above.

Teleflex’s GuideLiner was introduced in 2009 and enjoyed “undisputed commercial success and industry praise.” In 2019, Medtronic introduced its competing guide extension catheter (Telescope) and filed six inter partes review (IPR) petitions against Teleflex’s extension guide catheter family. Three of Medtronic’s petitions asserted that the challenged claims in three of Teleflex’s patents were obvious over the evacuation sheath assembly with a distal side opening used to aspirate embolic material while occluding blood flow using sealing balloons disclosed in a prior art reference (Ressemann). The other three petitions challenged claims of the other Teleflex patents as being obvious over a support catheter for delivering angioplasty balloons disclosed in a prior art reference (Kontos).

Medtronic specifically asserted that the following three elements of Teleflex’s claimed catheters were obvious:

  1. A proximal side opening. Medtronic argued that it would have been obvious to replace the proximal funnel structure of Kontos’s support catheter with the distal side opening of Ressemann’s evacuation sheath assembly.
  2. A catheter diameter that is no more than one French less than a corresponding guide catheter. Medtronic argued that in view of prior art mother-and-child dual catheter systems in which the child catheter’s diameter is no [...]

Lanham Act Liability May Apply to Copyrighted Material

The US Court of Appeals for the Ninth Circuit found that liability under the Copyright Act and liability under the Lanham Act are not mutually exclusive and that liability under the Copyright Act does not negate trade dress damages under the Lanham Act. Jason Scott Collection, Inc. v. Trendily Furniture, LLC, Case No. 21-16978 (9th Cir. May 30, 2023) (Wardlaw, Bumatay, Schreier (sitting by designation), JJ.)

Jason Scott Collection (JSC) and Trendily Furniture are high-end furniture manufacturers that sell their products in the Texas market. In 2016, Trendily intentionally copied three unique furniture designs by JSC and sold them to Texas retailers. Both collections featured heavy carved wood pieces with detailed embellishments and metal elements. The record showed that Trendily’s collection had been based on photographs of the preexisting JSC collection. The Trendily pieces were so similar that even JSC had initially mistaken the furniture as its own when confronted by a retailer. After JSC filed suit, the district court granted summary judgment to JSC on its copyright claim. Following a bench trial, the district court held Trendily liable on the trade dress claim. On that claim, the district court awarded almost $133,000 in prospective lost annual profits over a period of three years, which amounted to about six times the almost $20,000 in retrospective gross profits awarded on JSC’s copyright claim. Trendily appealed.

To obtain a judgment for trade dress infringement, a plaintiff must prove that the claimed trade dress is nonfunctional, the claimed trade dress serves a source-identifying role because it is either inherently distinctive or has acquired a secondary meaning and the defendant’s product creates a likelihood of confusion. Trendily argued that JSC had not adequately established a secondary meaning (for trade dress the parties stipulated was not inherently distinctive) or likelihood of confusion. The Ninth Circuit, however, found that the district court found adequate evidence of secondary meaning through copying and through confusion by retailers and consumers in the high-end furniture market. The Ninth Circuit also found that the district court had correctly found likelihood of confusion, putting special emphasis on Trendily’s intentional and precise copying of the JSC pieces leading to retailer confusion.

Turning to the damages award, Trendily argued that because copying is a commercially acceptable and necessary act in terms of competition, Trendily should only be held liable under the Copyright Act, rather than for trade dress infringement under the Lanham Act. However, the Ninth Circuit affirmed that liability under the Copyright Act and liability under the Lanham Act are not mutually exclusive and that liability under the Copyright Act did not negate the judgment against Trendily for trade dress damages under the Lanham Act. The Court then affirmed the trade dress damages award, finding that the prospective damages incurred when one of JSC’s business relationships fell apart because of Trendily’s copied furniture were reasonably foreseeable and had been “satisfactorily demonstrated.” The Court emphasized that the law only required “crude measures of damages in cases of intentional infringement.”

Finally, the Ninth Circuit affirmed [...]

All’s Well That Edwell: Two Markets Can Be Substantially Different if Defined Narrowly Enough

Despite evidence of actual confusion and seemingly similar services, the US Court of Appeals for the Tenth Circuit upheld a district court’s noninfringement finding concerning two nearly identical education-related marks because the parties targeted different goods and marketing channels. M Welles & Assocs., Inc. v. Edwell, Inc., Case No. 22-1248 (10th Cir. May 31, 2023) (Ebel, Bacharach, JJ.) (Tymkovich, J., dissenting). In his dissent, Judge Tymkovich criticized the lower court for characterizing the scope of the parties’ services too narrowly and observed that “[a]ny court can find some differences between businesses and markets at a particular level of generality.”

M Welles & Associates provides classes, seminars and certification workshops in the project management space under the brand name EDWEL (derived from “education done well”). The classes are designed for professionals in a variety of industries, including information technology, healthcare, education and the military. Welles primarily advertises its services via social media, Google and email, and further owns a variety of domain names incorporating both EDWEL and EDWELL. The defendant, Edwell, is a nonprofit organization that provides mental health coaching services to schoolteachers using the domain name Edwell.org and the brand name EDWELL (derived from “to be an educator and to be well”). Edwell operates by partnering with schools to provide its services and currently has partnerships with 10 K-12 public schools. Edwell does not target institutions of higher learning and does not offer services to corporations.

Welles first learned of Edwell’s services when it received a call from a potential customer asking about classes at Denver North High School—classes that were in fact offered by Edwell, not Welles. Welles sent a cease-and-desist notice to Edwell, which rebranded to “Educator Wellness Project” for a short time before reverting back to EDWELL. Welles then sued Edwell for trademark infringement, and the district court found that there was no likelihood of confusion. Welles appealed.

Welles raised three arguments on appeal:

  1. The magistrate judge used the wrong legal standard in assessing likelihood of confusion.
  2. The Tenth Circuit should adopt a presumption of confusion.
  3. The magistrate judge clearly erred in the analysis of Edwell’s intent, the similarity of the parties’ services and marketing, the degree of purchaser care and actual confusion.

Welles also moved to supplement the appellate record with new evidence of actual confusion that occurred after the trial.

Supplementation

The Tenth Circuit first addressed Welles’s motion, finding that there was no legitimate basis for supplementing the record. Fed. R. of Civ. P. 10(e) permits a court to modify the appellate record “only to the extent necessary to ‘truly disclose what occurred in the district court.’” Because the new evidence of actual confusion was not before the district court, the Tenth Circuit concluded that Rule 10(e) would not permit it to be added to the record. The Court further reasoned that the rare exception to Rule 10, which permits the court to supplement the record to correct misrepresentations, demonstrate mootness, or raise an issue for the first time on appeal, did not [...]

Electra Powers Second Circuit’s False Endorsement Analysis

Following on the heels of its 2021 decision in Electra v. 59 Murray, the US Court of Appeals for the Second Circuit affirmed the summary judgment denial of a Lanham Act claim related to false endorsement premised upon the unauthorized use of photographs in connection with promotional materials. Souza et. al. v. Exotic Island Enterprs., Inc., Case No. 21-2149 (2d Cir. May 19, 2023) (Lynch, Nardini, Menashi, JJ.) The Second Circuit also affirmed the district court’s summary judgment denial of Lanham Act false advertising and New York state right of publicity claims.

The operator of a gentlemen’s club used photographs of current and former professional models in social media posts promoting the club. The photographs were obtained without the models’ permission through a third-party vendor. The models sued the club operator asserting false endorsement, false advertising and right of publicity violations. The parties filed dueling summary judgment motions in February 2021. During the pendency of those motions, the Second Circuit decided Electra, a case involving overlapping plaintiffs suing on several of the same causes of action based on highly similar fact patterns. The district court subsequently granted the club operator’s motion for summary judgment and denied the models’ motion. The models appealed.

The Second Circuit relied heavily on its Electra decision to affirm the district court’s denial of the models’ false endorsement claim. To prevail on a false endorsement claim under Section 43 of the Lanham Act, the models were required to prove that there was a likelihood of confusion between their goods or services and those of the club operator. Likelihood of consumer confusion is evaluated using the eight Polaroid factors:

  1. Strength of the trademark
  2. Similarity of the marks
  3. Proximity of the products and their competitiveness with one another
  4. Evidence that the senior user may bridge the gap by developing a product for sale in the market of the alleged infringer’s product
  5. Evidence of actual consumer confusion
  6. Evidence that the imitative mark was adopted in bad faith
  7. Respective quality of the products
  8. Sophistication of consumers in the relevant market.

First, the models argued that the district court oversimplified the “strength of the mark” analysis (factor 1) to focus only on the recognizability of the mark. The Second Circuit disagreed, explaining that not only was Electra’s focus on recognizability binding precedent but also, that factor was required to be evaluated in the context of the mark’s strength in the false endorsement context (i.e., as a function of the extent to which the endorser’s identity could be linked with the product being sold). In other words, without an adequate showing that the models were recognized in the social media posts promoting the club, there could be no case of endorsement, let alone false endorsement.

Second, the models challenged the district court’s exclusion of their expert testimony on certain Polaroid factors. The district court excluded surveys conducted by the models’ expert as unreliable because they suffered from various methodological flaws and, therefore, did not provide a reliable [...]

PTO Seeks Comments on Strategies to Address Counterfeiting and Piracy

On May 25, 2023, the US Patent & Trademark Office (PTO) requested comments on strategies to address counterfeiting and piracy. The PTO requested information on current anti-counterfeiting and anti-piracy strategies that have proven effective, as well as ideas for future strategies.

The PTO requested comments on the 14 points listed below. Respondents may address any, all or none of these points. The PTO will receive any input relevant to future strategies in the fight to prevent counterfeited and pirated goods from entering the stream of commerce and reaching the hands of consumers.

1. Current anti-counterfeiting and anti-piracy strategies, and any trends in how often such practices guide plans for addressing these issues in the future.

2. The types of harms observed from sales of counterfeited and pirated goods.

3. How to educate consumers about the harms and dangers that may result from the use and sale of counterfeited or pirated products.

4. Current anti-counterfeiting and anti-piracy strategies that have proven successful, and those that have not. Information relating to targets of anti-counterfeiting and anti-piracy efforts, such as ecommerce platforms, physical markets and social media.

5. Anticipated challenges in the fight to prevent counterfeited and pirated goods from entering the stream of commerce and reaching the hands of consumers, and how to address those challenges.

6. Observed patterns and trends in counterfeiting and piracy during the COVID-19 pandemic. An indication of whether the commenter anticipates that such patterns and trends will continue post-pandemic.

7. Patterns and trends observed in counterfeiting and piracy due to shifts in the economy. An indication of whether the commenter anticipates that such patterns and trends will continue and if so, an explanation regarding the expected impact on current and future strategic plans to combat counterfeiting and piracy.

8. The commenter’s thoughts on whether any strategic plans to combat counterfeiting and piracy might include collaboration with private or public parties. If a strategic plan is not collaborative, why not? If collaborative, a discussion of the anti-counterfeiting and anti-piracy strategies employed in the collaboration.

9. New collaborative efforts contemplated to combat counterfeiting and piracy and factors that will affect implementation decisions. Discussion of how future collaborations might be composed.

10. Effective technologies to prevent counterfeited and pirated goods from entering the stream of commerce and reaching the hands of consumers, such as counterfeit product identification devices or advanced algorithms to secure supply chains and provide the identity of counterfeit goods online.

No Lost Value Damages Despite Trade Secret Misappropriation

The US Court of Appeals for the Second Circuit vacated a damages award, finding that although there was liability for appropriating trade secrets, the trade secret proprietor was only entitled to compensatory damages under federal trade secret law, not avoided cost damages based on alleged estimated research and development or loss of value. Syntel Sterling Best Shores Mauritius, Ltd., et al. v. The TriZetto Grp., Inc., et al., Case No. 21-1370 (2d Cir. May 25, 2023) (Wesley, Raggi, Lohier, JJ.)

This case involved trade secrets concerning healthcare insurance software called Facets® that was developed by TriZetto and alleged misappropriation by a TriZetto subcontractor, Syntel Sterling. In 2010, TriZetto and Syntel entered a Master Service Agreement (MSA) under which Syntel agreed to support TriZetto’s Facets customers. In exchange, TriZetto granted Syntel access to its trade secrets related to Facets. In 2012, the parties amended the MSA to allow Syntel to compete directly with TriZetto for consulting services. A dispute arose in 2014 when Syntel’s competitor Cognizant acquired TriZetto. Syntel terminated the amended MSA and requested payment of rebates owed. TriZetto refused, raising concerns about Syntel’s continued use of confidential trade secrets post-termination.

Syntel filed suit for breach of contract in the Southern District of New York, and TriZetto counterclaimed. During trial, TriZetto proceeded on trade secret misappropriation counterclaims related to the Facets software under the Defend Trade Secrets Act (DTSA) and New York law. Syntel argued that the amended MSA authorized Syntel to compete for Facets services business while using TriZetto’s trade secrets.

During discovery, the district court issued a preclusion order that sanctioned Syntel for discovery misconduct, finding that “Syntel was actively creating a repository of [TriZetto’s] trade secrets on its own . . . to be used in future work.” Citing the preclusion order, the district court instructed the jury that Syntel had misappropriated two of 104 asserted trade secrets.

With respect to damages, TriZetto presented expert testimony that established that Syntel avoided spending about $285 million in research and development costs because of the misappropriation covering the period between 2004 and 2014, an amount that covered only a portion of TriZetto’s overall $500 million research and development costs. Syntel’s expert did not counter that amount. Instead, Syntel argued that these avoided costs did not apply here for several reasons: because the alleged misappropriation did not destroy the value of Facets since Syntel could have used Facets for free by entering a third-party access agreement with TriZetto because TriZetto continued to make millions using its Facets software, and because Syntel was not a software company but a competing service provider. The jury instructions included Syntel’s avoided development costs as one form of unjust enrichment that applied to the federal claims but not the state claims.

The jury returned a verdict in favor of TriZetto on all counts. The jury awarded TriZetto $285 million in avoided development costs under the DTSA as compensatory damages and double that amount in punitive damages. Following trial, Syntel renewed its motion for judgment as [...]

Common Sense: Nonparties Not Precluded by Ex Parte Reexamination Termination

In a precedential decision, the US Patent & Trademark Office (PTO) Trademark Trial & Appeal Board denied a motion for judgment based on either claim or issue preclusion, and in the alternative for a show cause order, in a challenger’s petition. Common Sense Press Inc. d/b/a Pocket Jacks Comics v. Ethan Van Sciver and Antonio J. Malpica, Cancellation No. 92075375, 2023 BL 171365 (TTAB May 19, 2023) (Wellington, Pologeorgis, English, ATJs).

Common Sense Press filed a petition to cancel the registration for the mark “Comics Gate” for comics. In its petition, Common Sense asserted claims of nonuse, abandonment and fraud. The Respondents denied the allegations in the petition and also raised unclean hands by petitioner as a defense.

Common Sense also requested reexamination of the “Comics Gate” mark, which the PTO Director instituted on May 9, 2022. The cancellation proceeding was suspended pending the outcome of the reexamination. The Respondents were instructed to submit evidence to establish use of their mark for comics as of the August 13, 2020, deadline for filing a statement of use, as required under Section 1(d) of the Lanham Act.

The Respondents’ Section 1(d) statement showed that the “Comics Gate” mark was used in connection with comics sales in interest commerce and that such comics were provided via interest trade channels during the relevant period. In view of the Respondents’ evidence, the PTO Director determined that use had been demonstrated for comics and terminated the reexamination.

With the Notice of Termination in hand, the Respondents requested that the Board enter judgment in their favor in the cancelation proceeding as to nonuse and abandonment based on issue preclusion or, in the alternative, issue a show cause order to Common Sense as to why judgment should not be entered against them.

The Board denied the Respondents’ request, reasoning that termination of a reexamination proceeding does not preclude future nonuse challenges. Nor does such a reexamination termination decision have preclusive effect on a petitioner seeking cancellation, even if the petitioner requested the terminated reexamination. Citing due process concerns, the Board explained that the termination of an ex parte reexamination proceeding in which the petitioner necessarily does not participate may not serve as a basis for preventing the petitioner from raising even identical challenges in another action. The Board further noted that while the applicable statute “contains explicit estoppel provisions that bar the filing of future expungement or reexamination proceedings as to the identical goods or services once a proceeding of the same kind has been instituted . . . neither the statute nor regulations set forth a limitation on any party’s ability to petition to cancel a registration just because it is or has been the subject of a reexamination or expungement proceeding.” Thus, the Board concluded there is no basis to issue a show-cause order to a litigant who never appeared in a prior action.

Practice Note: This case serves as a reminder of the metes and bounds of an ex parte reexamination or expungement proceeding. Although [...]

Hairy Situation: Trademark Act Doesn’t Provide Consumer Standing

The US Patent & Trademark Office Trademark Trial & Appeal Board found that a consumer did not have standing to oppose an application for registration because the consumer failed to establish a commercial interest and injury that would be proximately caused by the registration of the mark. Rebecca Curtin v. United Trademark Holdings, Inc. (TTAB May 4, 2023) (Adlin, Lynch, Bunn, ATJs.)

Rebecca Curtin, a trademark law professor, has purchased various toys for her daughter. Curtin filed an opposition to United Trademark Holdings’ (UTH) application to register RAPUNZEL for use in connection with “dolls; toy figures.” Curtin alleged that RAPUNZEL fails to function as a trademark and is generic (or merely descriptive) of the identified goods and that UTH committed fraud. Curtin lamented that competition would be impeded if “private companies are allowed ‘to trademark the name of a famous fairytale character in the public domain,’” which would likely force consumers to pay higher prices for the relevant goods. Curtin also stated that allowing this registration “could chill the creation of new dolls and toys by fans of the Rapunzel fairytale, crowding out the substantial social benefit of having diverse interpreters of the fairytale’s legacy.”

More than four years ago, the Board denied UTH’s motion to dismiss, finding that Curtin had standing by relying on a case from 1999 that addressed the Trademark Act’s bar to registration for “immoral” or “scandalous” marks. Months after the Board’s initial decision, however, the Supreme Court ruled in Iancu v. Brunetti that the portion of the Trademark Act barring registration for “immoral” or “scandalous” marks was unconstitutional, and updates were issued on the “standard for determining whether a party is eligible to bring a statutory cause of action.”

A plaintiff has standing to oppose registration of a mark “when doing so is within the zone of interests protected by the statute and [opposer] has a reasonable belief in damage that would be proximately caused by registration of the mark.” Here, the Board explained that the statute at issue was the Trademark Act, which identifies its interest as regulating commerce and protecting plaintiffs with commercial interests: “[A] mere consumer that buys goods or services is not under the Trademark Act’s aegis.”

Moreover, Curtin failed to demonstrate that an injury would result from registration of the mark. The Board was unconvinced by Curtin’s explanations of the potential harm to competition and resulting higher prices for consumers, stating that the “allegations of damage are [] too remote, because the alleged damage to Opposer depends first on the alleged effect of registration on other commercial doll markets or sellers.” The Board, therefore, dismissed the opposition.

Well Runs Dry: Summary Judgment Denial Supports Non-Exceptional Case Finding

The US Court of Appeals for the Federal Circuit affirmed a district court’s denial of attorneys’ fees, explaining that when a district court denies summary judgment and allows a plaintiff’s case to proceed, the district court effectively determines that the position of the party opposing summary judgment is not objectively baseless. OneSubsea IP UK Limited v. FMC Techs, Inc., Case No. 22-1099 (Fed. Cir. May 23, 2023) (Moore, Clevenger, Dyk, JJ.)

OneSubsea and FMC compete in the subsea oil and gas exploration and extraction industry. In March 2015, OneSubsea filed a lawsuit against FMC alleging infringement of 95 claims across 10 OneSubsea patents. After the district court issued its claim construction ruling, FMC moved for summary judgment of noninfringement. OneSubsea opposed. While the summary judgment motion was pending, the Patent Trial & Appeal Board instituted inter partes review (IPR) proceedings on a subset of the asserted patents. FMC argued that while a stay of district court proceedings would be appropriate, it was unnecessary in light of its pending summary judgment motion. In August 2016, the district court denied summary judgment and stayed the case.

The case remained stayed for three years, during which time the Board invalidated 76 claims. In 2019, the district court lifted the stay. At a pre-trial hearing in 2020 discussing whether additional discovery was needed to address summary judgment, FMC doubted the need for more discovery and pointed to the 3,200 record pages illustrating differences between the designs of the accused device and the patented devices. In response, the district court stated, “And you really think I’m going to be able to grant summary judgment on that?” After the hearing, FMC renewed its summary judgment motion, which OneSubsea opposed. In reply, FMC moved to exclude the report of OneSubsea’s expert because he applied the wrong claim construction. Ultimately, the district court granted FMC’s motion to exclude and its motion for summary judgment.

In 2021, FMC moved for attorneys’ fees based on OneSubsea’s “substantively weak infringement claims” after the claim construction order was issued and “litigation misconduct.” After briefing was complete, the district court announced that the case had been reassigned to another judge following the retirement of the original assigned judge. The new judge rejected FMC’s view that OneSubsea’s case was objectively baseless and further rejected FMC’s claims of litigation misconduct. FMC appealed.

As a threshold matter, FMC argued that the Federal Circuit should apply de novo review instead of an abuse-of-discretion standard because the new judge only briefly “lived with the case” and should be disqualified from exercising discretion in deciding FMC’s attorneys’ fees motion. The Court rejected FMC’s invitation to change the standard of review, citing the substantial body of law in which appellate courts have consistently reviewed successor judges’ decisions on discretionary issues for abuse of discretion.

Turning to the merits, the Federal Circuit found that FMC’s exceptional case argument lacked merit. The Court explained that the argument disregarded the district court’s observation that FMC’s demand for a prompt favorable noninfringement judgment based [...]
