What we have here is a failure to communicate: Expert must map all claim limitations to the accused infringement

by Benjamin Ediger, Ph.D. | Oct 2, 2025 | Patents

The US Court of Appeals for the Federal Circuit reversed jury verdicts of infringement, finding that they were not supported by substantial evidence because of deficiencies in the patent owner’s expert testimony. Finesse Wireless LLC v. AT&T Mobility LLC, Case No. 2025 WL 2713518 (Fed. Cir. Sept. 24, 2025) (Moore, C.J.; Linn, Cunningham, JJ.)

AT&T Mobility was accused of infringing two patents owned by Finesse Wireless, both directed to methods for mitigating intermodulation product interference in radios. The accused technology involved Nokia radios implementing passive intermodulation (PIM) cancellation. Nokia intervened in the case. A jury found all asserted claims valid and infringed, awarding Finesse more than $166 million in lump sum damages. AT&T and Nokia moved for judgment as a matter of law (JMOL) on both noninfringement and the damages award, and alternatively sought a new trial. The district court denied the motions. AT&T and Nokia appealed.

The Federal Circuit reversed the district court’s denial of JMOL on noninfringement and vacated the damages award, concluding that the jury verdicts were not supported by substantial evidence. The Court’s decision turned largely on shortcomings in the testimony of Finesse’s infringement expert, whose analysis was the sole basis for Finesse’s infringement case.

For the first patent, the Federal Circuit found that Finesse’s expert failed to demonstrate that Nokia’s PIM cancellation feature received all input signals required by the asserted claims. The expert relied on a Nokia diagram but misinterpreted it by mistakenly identifying a signal generated by the radio as one of the required input signals. Although the expert was made aware of the error, he did not clearly correct his position or identify alternative signals that satisfied the claim limitation. Finesse argued that the expert had corrected a “misimpression,” but the Court disagreed, finding that the expert failed to provide a clear and consistent explanation reconciling his contradictory positions.

The asserted claims of the second patent required seven multiplications involving three signals. Finesse’s expert relied solely on a Nokia document that listed only three multiplications yet equated them to the seven required by the claims. The Federal Circuit found this testimony inadequate, noting that the expert failed to explain how the three multiplications mapped to the seven required. On appeal, Finesse argued that the document actually evidenced 10 multiplications, but the Court was unpersuaded. Neither Finesse nor its expert explained how the 10 multiplications corresponded to the seven required multiplications, nor did they reconcile this new position with the expert’s prior reliance on only three multiplications.

Because Finesse failed to present expert testimony that adequately mapped each claim limitation to the accused method, the Federal Circuit reversed the jury’s infringement findings for both patents and vacated the damages award.

Practice note: The decision underscores the importance of detailed and consistent expert analysis in patent infringement cases, particularly when expert testimony is the sole basis for proving infringement.

Bank on it: Likelihood of confusion analysis requires factual consistency when evaluating DuPont factors

by Taylor MacDonald | Oct 2, 2025 | Trademarks

The US Court of Appeals for the Federal Circuit reversed in part a decision by the Trademark Trial & Appeal Board and remanded for new analysis of two factors under the Dupont likelihood of confusion test. The Court emphasized that the factual determination in factor two (similarity of the parties’ goods or services) should remain consistent through the analyses for factors one and six. Apex Bank v. CC Serve Corp., Case No. 23-2143 (Fed. Cir. Sept. 25, 2025) (Moore, Hughes, Cunningham, JJ.)

CC Serve has held a registration for the word mark ASPIRE in connection with credit card services since 1998. In 2019, Apex Bank, a Tennessee-based banking chain, filed intent-to-use applications at the US Patent & Trademark Office (PTO) for marks incorporating ASPIRE BANK for use in “banking and financing services.” CC Serve, which partners with banks to issue and service credit cards, filed a letter of protest during Apex’s trademark prosecution. Despite CC Serve’s objections, the PTO published Apex’s marks in December 2019. CC Serve then formally opposed the marks, and the Board sustained the opposition, finding a likelihood of consumer confusion. Apex appealed.

The Federal Circuit reviewed the Board’s findings under the DuPont framework, which assesses likelihood of confusion based on multiple factors. Apex challenged the Board’s analysis of three specific factors:

Factor two: Similarity of the parties’ goods/services
Factor six: Strength of the prior mark in the marketplace
Factor one: Similarity of the marks themselves

The Federal Circuit upheld the Board’s finding under factor two, agreeing that “credit card services” and “banking/financing services” are highly similar based on their definitions and market overlap.

However, the Federal Circuit found fault with the Board’s analysis under factor six, which evaluates third-party use of similar marks to determine the strength of the contested mark. Apex submitted many examples of ASPIRE marks used in both the credit card and broader financial services industries. The Board, however, narrowed its focus to only those marks used in credit card services, excluding broader banking and financial services. The Federal Circuit concluded that this was inconsistent with the Board’s finding under factor two regarding the similarity of the parties’ goods and services. The Court instructed that on remand, the Board should consider third-party ASPIRE marks across both industries.

The Federal Circuit also directed the Board to revisit factor one, which assesses the similarity of the marks in light of the strength of the prior mark. Whether the strength of CC Serve’s mark is diminished when viewed in the broader financial services context could affect the “overall commercial impression” of the marks and the likelihood of confusion.

The Federal Circuit emphasized that factual determinations, particularly regarding the similarity of goods and services, must be applied consistently across the DuPont factors. The Court therefore remanded the case to the Board for reconsideration of factors one and six considering this guidance.

Functional relationship recitation can’t overcome anticipating prior art

by Tim Dunker | Oct 2, 2025 | Patents

Underscoring functional relationships as limitations in patent claims and the importance of claim construction, the US Court of Appeals for the Federal Circuit affirmed in part, vacated in part, and remanded a Patent Trial & Appeal Board decision that found claims of a patent unpatentable notwithstanding a functional relationship recitation. Bayer Pharma Aktiengesellschaft v. Mylan Pharmaceuticals Inc., et al., Case No. 23-2434 (Fed. Cir. Sept. 23, 2025) (Moore, Cunningham, Scarsi, JJ.)

Bayer owns a patent that describes the results of a phase III clinical trial that evaluated the efficacy and safety of administering rivaroxaban with and without aspirin for the prevention of major adverse cardiac events. Certain claims require “administering to the human patient rivaroxaban and aspirin in amounts that are clinically proven effective in reducing the risk of myocardial infarction, stroke or cardiovascular death[,] wherein rivaroxaban is administered in an amount of 2.5 mg twice daily and aspirin is administered in an amount of 75 – 100 mg daily.” Other claims are directed to a once daily administration of “a first product comprising rivaroxaban and aspirin” and “a second product comprising rivaroxaban.”

Mylan challenged the patent in inter partes review (IPR), arguing that certain claims were anticipated by the Foley reference and others were obvious over Foley alone or in combination with Plosker. The Board agreed, finding all challenged claims unpatentable. Bayer appealed.

Bayer argued that the Board erred in:

Construing “clinically proven effective” as non-limiting and finding, in the alternative, that it was inherently anticipated
Construing “first product comprising rivaroxaban and aspirin” to encompass administration of rivaroxaban and aspirin as separate dosage forms
Failing to articulate why a skilled artisan would have combined Foley and Plosker with a reasonable expectation of success
Failing to analyze whether clinical proof of efficacy was an unexpected result

The Federal Circuit declined to resolve whether “clinically proven effective” is a limiting claim element, concluding that even if it were, it would not render the claims patentable. The Court explained that the phrase does not create a “new and unobvious functional relationship” with the known method of treatment. Analogizing to a hypothetical claim for a known drug method modified by a post-dated accolade (e.g., “Best Drug of 2026”), the Court emphasized that requiring clinical proof of efficacy does not transform the underlying treatment process.

Bayer relied on the Federal Circuit’s 2019 decision in Allergan Sales v. Sandoz, in which the Court found “wherein” clauses specifying safety and efficacy to be material to patentability. The Federal Circuit distinguished Allergan, noting that the claims there were written in open format and the “wherein” clauses modified the overall composition. In contrast, the claims of Bayer’s patent already specified exact dosages, and “clinically proven effective” did not modify any particular component. The Court therefore affirmed the Board’s finding of unpatentability for these claims.

However, the Federal Circuit agreed with Bayer on the construction of claims requiring a “first product comprising rivaroxaban and aspirin.” Bayer argued that this language required a single dosage [...]

The smoke has cleared – and so has your invalidity defense

by Jodi Benassi | Sep 25, 2025 | America Invents Act, Patents

The US District Court for the Northern District of Iowa issued an instructive decision clarifying the scope of statutory estoppel under the Leahy-Smith America Invents Act (AIA) following post-grant review (PGR) proceedings before the Patent Trial & Appeal Board. Intirion Corp. v. College Products, Inc., Case No. 23-cv-4023-CJW-KEM (N.D. Iowa Sept. 16, 2025) (Williams, J.)

Intirion brought a patent infringement suit against College Products, which responded by petitioning the Board for PGR, challenging the patents based on obviousness and indefiniteness. While the PGR was pending, the district court proceeded with claim construction and initially found the terms “level of smoke,” “amount of smoke,” and “dangerous condition” indefinite. Intirion moved for reconsideration, and College Products filed a motion for partial summary judgment asserting invalidity. Intirion also sought a stay of the litigation pending the PGR outcome, which the court granted.

The Board instituted review of all claims. Initially, it found that neither party had requested express construction of any terms and adopted Intirion’s interpretation that “level of smoke” and “amount of smoke” meant “merely detecting smoke,” based on Intirion’s representations in the district court. In its final written decision (FWD), the Board acknowledged the district court’s indefiniteness findings but ultimately adopted the plain and ordinary meaning of the terms, concluding that a person of ordinary skill in the art could determine appropriate thresholds using known methods. Expert testimony persuaded the Board that defining the terms by their function was sufficiently definite under patent law.

After the Board upheld the claims, the district court found that College Products was estopped under 35 U.S.C. §325(e)(2) from asserting any invalidity grounds (including indefiniteness and obviousness) that were or reasonably could have been raised during the PGR. The district court explained that the AIA established a streamlined system allowing third parties to challenge the patentability of issued claims before the Board as a quicker and more cost-effective alternative to litigation. This structure is specifically designed to prevent challengers from getting multiple bites at the apple by raising the same or similar arguments in subsequent court proceedings.

College Products argued that estoppel should not apply because it filed its motion for partial summary judgment before the Board issued its FWD. The district court rejected this argument, explaining that the statutory language provides no exception based on timing and imposes a clear bar once the Board has issued a FWD. The district court also found that College Products’ position was inconsistent with applicable case law and noted that it failed to cite any contrary authority.

The district court further explained that it had intentionally deferred ruling on College Products’ motion for partial summary judgment of invalidity pending the outcome of the PGR proceedings. Once the PTAB issued its FWDs, College Products was estopped from further challenging the validity of the patents, including through its pending summary judgment motion, because it could have raised any such indefiniteness arguments during the PGR process.

Practice note: Unlike inter partes review (IPR), during PGR a petitioner can challenge patentability on grounds [...]

DMCA safe harbor: Prelude to a Supreme Court encore?

by Jodi Benassi | Sep 18, 2025 | Copyrights

The US Court of Appeals for the Second Circuit granted in part and denied in part Capitol Records’ petition for reconsideration of the Court’s January 13, 2025, decision in Capitol Records v. Vimeo. In that ruling, the Court determined that Capitol Records had waived the argument that Vimeo’s encouragement of users to make infringing lip-dub videos may constitute a form of right and ability to control infringement – an apparent forfeiture of the safe harbor provided by the Digital Millennium Copyright Act (DMCA). In its reconsideration decision, the Court removed a footnote regarding whether the “right and ability to control” argument was preserved for Supreme Court review. Capitol Records, LLC, et al. v. Vimeo, Inc., et al., Case Nos. 21-2949; -2974 (2d Cir. Sept. 9, 2025) (Leval, Parker, Merriam JJ.)

Capitol Records filed a petition for reconsideration of the Second Circuit’s decision, which found that Capitol had waived its argument under Metro-Goldwyn-Mayer Studios v. Grokster. A central issue was application of the Grokster precedent, which addressed inducement of copyright infringement. Capitol Records argued that Vimeo’s encouragement of users to create infringing lip-dub videos constituted a “right and ability to control” infringement, potentially forfeiting the DMCA safe harbor protection.

In its earlier ruling, the Second Circuit found that Capitol Records had waived this argument by not adequately presenting it in the appellate brief, despite having discussed it in the fact section. The Court emphasized that the argument was not developed in the argument section of the brief and, in a footnote, noted that Capitol Records had acknowledged that the argument was foreclosed by a prior ruling. Capitol Records argued that its waiver was not of the Grokster-based theory of forfeiture of the safe harbor, but rather of a claim under Grokster for induced infringement. The Court was not persuaded, noting that Capitol Records’ opening brief made no distinction between a Grokster-based inducement claim and a Grokster-based theory for forfeiting DMCA safe harbor protection. As a result, the Court rejected Capitol Records’ argument that the Grokster-based theory had not been waived.

In its most recent ruling, the Second Circuit granted Capitol’s petition to remove language from a footnote in the Court’s prior ruling that suggested Capitol’s Grokster inducement theory, based on the “right and ability to control,” was barred from Supreme Court review.

Practice note: The Second Circuit’s decision to partially grant and deny the petition for reconsideration clarifies the procedural requirements for preserving arguments on appeal and reinforces the complexities of applying traditional copyright principles to digital platforms. As the case progresses, stakeholders in the music and technology industries should monitor developments and implications for the DMCA and copyright enforcement.

Oh brother: Draft settlement agreements carefully

by Ashley K. Justice | Sep 18, 2025 | Copyrights, Trademarks

The US Court of Appeals for the Eighth Circuit affirmed a district court judgment, finding that the plaintiff failed to sufficiently prove damages for its copyright claim, the jury instructions accurately applied the sophisticated consumer exception to initial-interest confusion, and the district court properly submitted ambiguous contract language to the jury for interpretation. Hoffmann Brothers Heating and Air Conditioning, Inc. v. Hoffmann Air Conditioning & Heating LLC, Case No. 24-1289 (8th Cir. Sept. 8, 2025) (Graza, Stras, Kobes, JJ.)

Brothers Tom and Robert Hoffmann were partners in Hoffmann Brothers. After Robert bought out Tom, they entered into a settlement agreement that included a four-year restriction barring Tom from using the name “Hoffmann” in connection with an HVAC business. After four years, Tom began using “Hoffmann Air Conditioning & Heating, LLC” (Hoffmann AC). Hoffmann AC’s advertising agency later mistakenly used pictures of Hoffmann Brothers. Hoffmann Brothers sued for trademark and copyright infringement. Hoffmann AC prevailed on some issues at summary judgment, and the jury reached a mixed verdict on the remaining claims. Both parties were denied attorneys’ fees, and Hoffmann Brothers appealed.

On appeal, the Eighth Circuit affirmed that Hoffmann Brothers did not sufficiently prove damages for its copyright claim based on Hoffmann AC’s use of its photographs. Because the photographs were unregistered works, Hoffmann Brothers was required to prove actual damages and/or additional profits of the infringer attributable to the infringement. Hoffmann Brothers’ only evidence of actual damages was Hoffmann AC’s monthly fee paid to its marketing agency. The Court found that using the monthly fee was too speculative because it did not reflect the benefit to Hoffmann AC or the harm to Hoffmann Brothers. For evidence of additional profits, Hoffmann Brothers’ expert report failed to link the use of the photographs to Hoffmann AC’s gross revenue. The Court explained that the Hoffmann Brothers could have linked additional profits attributable to the use of the photographs by, for example, demonstrating that:

Hoffmann AC gained customers because of the ads.
The photographs actually influenced purchasing decisions.
There was spike in monthly revenue that coincided with use of the photographs.

Regarding Hoffmann Brothers’ trademark claim, the jury found that the names were not so similar as to cause confusion. Hoffmann Brothers appealed, arguing that the district court erred in its jury instructions. The Eighth Circuit rejected the argument, finding the instructions fair and legally adequate. The instruction was directed to the issue of initial-interest confusion (a concept not adopted by Missouri courts), which occurs when consumer confusion arises at the outset, even if no sale ultimately results. The Court explained that under Eighth Circuit precedent, a sophisticated consumer exception applies to this theory, meaning that consumers who exercise a high degree of care are less likely to be initially confused. Here, the district court instructed the jury to consider initial-interest confusion only if it found that Hoffmann Brothers’ customers were not sophisticated. While the Eighth Circuit acknowledged some hesitation about the assumption that sophisticated consumers are never susceptible to initial-interest [...]

Penny for your characters? Victorian tropes not so striking or protectable

by Anisa Noorassa | Sep 18, 2025 | Copyrights

The US Court of Appeals for the Ninth Circuit affirmed a district court’s dismissal of a copyright infringement claim finding that the plaintiff had not plausibly alleged copying of protected characters. Anna Biani v. Showtime Networks, Inc. et al., Case No. 24-3949 (9th Cir. Sept. 8, 2025) (Nguyen, Mendoza, Kernodle, JJ.)

Biani sued Showtime alleging that the series “Penny Dreadful” infringed on three original characters she created for an online role-playing forum. Biani claimed that Showtime incorporated various aspects of her characters into two of the show’s characters and alleged that the defendants had access to her work because of the similarities between the characters. The district court dismissed the complaint, finding that Biani failed to plausibly allege that Showtime had a reasonable opportunity to copy her work. The district court applied the extrinsic test for protectable material under copyright, filtering out characteristics considered to be stock aspects of the Victorian-era England genre, and found that any remaining similarities were not striking enough to preclude the possibility of independent creation. Biani was granted leave to amend but chose not to, leading to the dismissal of the case with prejudice. Biani appealed.

The Ninth Circuit affirmed the dismissal of Biani’s complaint for failure to state a claim. The Court explained that to state a claim for copyright infringement, a plaintiff must plausibly allege both ownership of a valid copyright and that the defendant copied protected aspects of the work, which includes factual copying and unlawful appropriation. Biani did not challenge the district court’s determination that she failed to plausibly allege evidence of access. Instead she argued that the similarities between the works were so striking as to preclude independent creation. While the panel concluded that the district court improperly filtered out unprotectable elements of the works, it found this error was harmless because Biani’s allegations were insufficient to plausibly infer copying. The Court found that any resemblance between the characters was not extensive enough to preclude the possibility of coincidence, independent creation, or prior common source.

The Ninth Circuit also held that Biani’s claim failed under the “unlawful appropriation” analysis, agreeing with the district court that Biani failed to allege substantial similarity in protectable expression. The Court applied the extrinsic test to assesses the objective similarities of the two works, focusing only on the protectable elements of the plaintiff’s expression. The Court found that many of the characteristics that Biani alleged were unique to her characters (such as their age, strength, beauty, and engagement in witchcraft) were actually unprotectable elements, common in the public domain, and a standard aspect of Victorian-era-based fiction. The Court thus concluded that Biani failed to allege substantial similarity in protectable expression and thus affirmed the district court’s dismissal.

Surprise? Last-minute new theory leads to new trial

by Dexter Hamilton | Sep 18, 2025 | Patents

The US Court of Appeals for the Federal Circuit reversed a district court’s denial of a new trial after the defendant introduced a new noninfringement theory on the eve of trial based on test results it previously refused to produce, saying they were not necessary. Magēmā Technology LLC v. Phillips 66, Phillips 66 Co., and WRB Refining LP, Case No. 2024-1342 (Fed. Cir. Sept. 8, 2025) (Moore, Stoll, Bumb, JJ.)

Magēmā owns a patent directed to a solution to desulfurize fuel used to power cargo ships. Magēmā entered into licensing discussions with Phillips, but after the parties failed to reach an agreement, Phillips modified its hydrotreater reactors to implement what Magēmā believed was an infringing desulfurization process. Magēmā sued.

The governing fuel standard required a flashpoint of at least 140 degrees, meaning fuel with a pre-hydroprocessing flashpoint below that threshold would not infringe. The parties disagreed on where at the refinery the flashpoint should be tested. Phillips provided data from one sampling point while Magēmā requested data from a location closer to the hydrotreater reactor. Phillips refused, citing safety concerns, and argued that Magēmā could estimate the flashpoint using an accepted formula. The district court denied Magēmā’s motion to compel, agreeing that the formula sufficed. However, after discovery closed, Phillips moved to supplement the summary judgment record with new flashpoint test results from a different sampling station. The district court denied the motion, finding Phillips had no reasonable explanation for failing to sample earlier, and that introducing the evidence late would be unduly prejudicial, especially since Phillips had previously said Magēmā could rely on the formula. Yet shortly before jury selection, Magēmā learned that Phillips intended to argue that the formula was inadequate and that only actual testing could prove infringement (evidence Magēmā lacked), effectively shifting the burden. Magēmā objected, but the district court overruled the objection.

At trial, Philips told the jury that the standard required actual flashpoint testing and that Magēmā could not prove infringement without test samples. Magēmā requested a curative instruction, which the district court denied. The district court also barred Magēmā from explaining why it had relied on a formula rather than actual testing data. The jury returned a general verdict of noninfringement. Although the district court acknowledged that Phillips’ arguments were “improper and prejudicial,” it denied Magēmā’s motion for a new trial, finding that the misconduct did not affect the outcome. Magēmā appealed.

Phillips argued that Magēmā had failed to timely object, but the Federal Circuit disagreed, citing to Magēmā’s pre-jury selection objection, request for a curative instruction, and motion for a new trial. Finding that the district court abused its discretion in denying a new trial, the Federal Circuit agreed that Phillips’ argument was “improper and prejudicial,” characterizing it as a “bait-and-switch.”

Because the jury returned a general verdict form, the Federal Circuit could not determine the basis for the noninfringement finding and, given the repeated emphasis Phillips placed on its improper argument, the Court concluded it would be unjust to let the [...]

Solidarity: Union’s commercial use may be Lanham Act violation

by Cecilia Choy, Ph.D. | Sep 18, 2025 | Trademarks

The US Court of Appeals for the Ninth Circuit reversed and remanded a district court’s dismissal of a Lanham Act action, finding that this case was not the rare instance where there was no plausible likelihood that a reasonably prudent consumer would be confused about the origin of the goods that allegedly bore the distinctive marks at issue. Trader Joe’s Co. v. Trader Joe’s United, Case Nos. 24-720; -2826 (9th Cir. Sept. 8, 2025) (Sanchez, Thomas, Donato, JJ.)

Trader Joe’s, a US grocery store chain, owns the red typeface logo and sells reusable tote bags and other branded goods bearing its marks. Trader Joe’s United (TJU), a labor union representing certain Trader Joe’s employees, markets (for profit) various products via its website, including reusable tote bags. Its website header features a logo that uses the distinctive red typeface and the concentric circle design in Trader Joe’s logo. The image below shows totes from Trader Joe’s (left) and TJU (right).

TJU allegedly began using Trader Joe’s marks in commerce, and Trader Joe’s sent TJU a cease-and-desist letter. Trader Joe’s noted that its demand was directed solely at TJU’s commercial use of the marks on merchandise sold to consumers on the TJU website, not the reference to Trader Joe’s to identify the union or discuss the union’s cause.

Trader Joe’s sued TJU, asserting several claims, including trademark infringement, and sought to permanently enjoin TJU from using Trader Joe’s trademarks in connection with the sale of commercial merchandise on the TJU website. Trader Joe’s also sought the destruction of all infringing merchandise and recovery of damages. TJU moved to dismiss, arguing that Trader Joe’s filed its trademark infringement complaint in retaliation over an ongoing labor dispute and asserting that there was no plausible likelihood that a consumer would believe that products sold on TJU’s website were sponsored, endorsed, or approved by Trader Joe’s.

Applying the Sleekcraft likelihood-of-confusion factors, the district court agreed with TJU and noted several differences between the marks. The district court also explained that Trader Joe’s does not sell many of the products sold on TJU’s website, including buttons, t-shirts, and mugs. The district court concluded that confusion about the origin of these products was unlikely for a reasonable consumer because TJU’s website clearly identified itself as a website of a labor union and was openly critical of Trader Joe’s labor practices. Trader Joe’s appealed.

The Ninth Circuit concluded that when the allegations were viewed in the light most favorable to Trader Joe’s, the district court erred when applying the fact-specific likelihood-of-confusion test. To prevail on a trademark infringement claim, Trader Joe’s would need to establish that it had a protectible ownership interest in the mark and that TJU’s use of the mark was likely to cause consumer confusion. To determine whether a reasonably prudent consumer [...]

Fifth Circuit untangles damages in trademark battle

by Christian Tatum | Sep 18, 2025 | Trademarks

The US Court of Appeals for the Fifth Circuit reinstated a jury’s lost profits and breach damages awards that the district court set aside during post-trial proceedings, finding that sufficient evidence supported the awards. I&I Hair Corp. v. Beauty Plus Trading Co., Case No. 24-10374 (5th Cir. Sept. 5, 2025) (Haynes, Ho, Oldham, JJ.) (per curiam).

I&I Hair, the seller of EZBRAID synthetic braids, sued competitor Beauty Plus for trademark infringement, unfair competition, and breach of a 2019 settlement agreement that prohibited Beauty Plus from using the EZBRAID mark or confusingly similar terms. At trial, the jury awarded approximately $70,000 for infringement, $1.15 million in lost profits for unfair competition, and $1.3 million for breach of the settlement agreement.

After trial, the district court set aside the unfair competition and breach awards, concluding I&I failed to prove lost profits with reasonable certainty. I&I appealed.

The Fifth Circuit reversed, emphasizing that Texas law requires only competent evidence permitting a jury to determine lost profits with reasonable certainty, not precise proof of the exact amount awarded. The Court found that I&I had met this standard, highlighting evidence that EZBRAID sales surged by 400% in 2017 – 2018 and 70% in 2018 – 2019 but slowed to 10% growth in 2019 – 2020 after Beauty Plus began selling similar products. I&I’s sales declined further as Beauty Plus sold more than $5 million in infringing goods from 2019 to early 2022, with Beauty Plus making sales to nearly half of I&I’s customers. I&I also introduced revenue and profit margin data, as well as testimony that brand dilution and supply chain disruption amplified the harm. The Court concluded that the jury may have rationally considered I&I’s pre-infringement growth in revenue and net income, as well as testimony regarding customer confusion, to reach the damages awarded.

The Fifth Circuit rejected each of Beauty Plus’ arguments. First, it rejected Beauty Plus’ claim that the unfair competition award improperly mirrored Beauty Plus’ profits, explaining that the question was whether the number fell within the range supported by evidence, not whether it matched I&I’s calculations precisely. Second, the Court dismissed Beauty Plus’ challenge to the breach award, noting that Texas law requires certainty only as to the fact of damages, not the exact amount. Finally, the Court found I&I had adequately preserved its opposition to Beauty Plus’ judgment as a matter of law motion.

Accordingly, the Fifth Circuit reinstated the jury’s full verdict and remanded the case for further proceedings on attorneys’ fees.
