Staton Techiya v. Samsung: Federal Circuit Affirms Personalized Hearing Patent Ruling
Staton Techiya, LLC challenged Samsung Electronics over US9609424B2, a patent covering methods and devices for personalized hearing. The Federal Circuit affirmed the lower tribunal’s decision after 773 days of proceedings, leaving the patentability ruling undisturbed and closing off further appellate challenge at this level.
Federal Circuit closes Samsung personalized hearing patent appeal
Staton Techiya, LLC, a patent assertion entity holding US9609424B2 — a patent directed to methods and devices for personalized hearing — brought this appeal before the Court of Appeals for the Federal Circuit as Case No. 23-2335. The underlying dispute centred on patentability, specifically an invalidity or cancellation action targeting the ‘424 patent. Samsung Electronics Co., Ltd. and its U.S. subsidiary Samsung Electronics America, Inc. were named as appellees, represented by Arnold & Porter Kaye Scholer LLP.
The Federal Circuit issued its order on 9 October 2025, affirming the decision of the lower tribunal in full. The court’s order — ‘AFFIRMED’ — means the appellate panel found no reversible legal or factual error in the proceeding below, leaving the patentability determination intact. Although the basis of termination is recorded as ‘Appeal Dismissed,’ the operative verdict is an affirmance on the merits, which is the authoritative outcome for analytical purposes. Staton Techiya’s challenge to the invalidity or cancellation finding did not succeed at the Federal Circuit.
The 773-day duration from filing to disposition suggests a substantive appellate review rather than a rapid procedural termination, consistent with briefing cycles and panel consideration typical of Federal Circuit patent validity appeals. What drove the specific grounds of affirmance — whether claim construction, prior art analysis, or procedural posture — is not disclosed in the public record. No further appeal as of right exists at this level; Staton Techiya’s remaining option would be a petition for certiorari to the U.S. Supreme Court, a path rarely granted in patent validity matters.

Federal Circuit affirms: what the ruling means for both parties
What ‘AFFIRMED’ means at the Federal Circuit
An affirmance means the Federal Circuit panel reviewed the record and found no reversible error in the lower tribunal’s decision. The appellate court does not retry the case; it examines whether the tribunal below correctly applied the law and whether factual findings were supported by substantial evidence. An affirmance is the appellate court’s endorsement that the outcome below was legally sound, and it carries full precedential weight for the parties.
No reversible error foundStaton Techiya’s appeal fails — invalidity finding stands
As appellant, Staton Techiya bore the burden of demonstrating reversible error in the lower invalidity or cancellation ruling. The Federal Circuit’s affirmance means that burden was not met. The patentability challenge to US9609424B2 has been upheld, and the ‘424 patent’s enforceability is therefore diminished or extinguished depending on the scope of claims cancelled or invalidated below. The only remaining avenue is a Supreme Court certiorari petition, which is rarely granted in patent validity disputes.
Enforceability diminishedSamsung prevails — patent validity challenge confirmed on appeal
Samsung and Samsung Electronics America secured affirmance of the lower ruling, confirming that the invalidity or cancellation determination withstood Federal Circuit scrutiny. This outcome insulates Samsung from infringement exposure under US9609424B2 to the extent claims were cancelled or invalidated. The affirmance also raises the bar for any future attempt by Staton Techiya to assert the same patent claims against Samsung or any other party in the consumer electronics space.
Infringement risk removedPersonalized hearing IP landscape shifts after affirmance
The Federal Circuit’s affirmance signals that the claims of US9609424B2 as challenged could not survive patentability scrutiny, which may encourage competitors and product teams in the audio personalisation and hearable device sector to operate with greater freedom around this patent’s scope. Companies designing personalized hearing features — including beamforming, adaptive EQ, and user audio profiling — should reassess their FTO posture in light of this outcome, as the invalidated claims may no longer present a blocking risk.

Official order — verbatim text
The Federal Circuit’s order — ‘AFFIRMED’ — is categorical: the panel found no reversible error in the lower tribunal’s patentability determination regarding US9609424B2. At the appellate level, the standard of review for legal questions such as claim construction is de novo, while underlying factual findings — including prior art determinations in cancellation proceedings — are reviewed for substantial evidence. An unqualified affirmance signals the lower ruling was sound on both dimensions, and the outcome is binding on the parties without remand.
US9609424B2 — Method and Device for Personalized Hearing
US9609424B2, filed under application number US15/144741, protects methods and devices for personalized hearing — a technical domain encompassing adaptive audio processing tailored to individual user hearing profiles. The patent likely covers signal processing approaches that characterise a user’s hearing capability and adjust audio output accordingly, a function increasingly embedded in consumer earbuds, hearing aids, and smart audio devices. The patent’s grant reflects a period of rapid innovation in personalised acoustics and hearable technology.
From a competitive intelligence perspective, US9609424B2 sits at the intersection of consumer electronics and audiology — a sector where Samsung, Apple, Sony, and Bose have all made significant hardware and software investments. Assertion of this patent against Samsung suggests the claims were drafted broadly enough to implicate mass-market audio products. The Federal Circuit’s affirmance of the invalidity or cancellation ruling suggests the claim set did not withstand prior art scrutiny, which may reduce blocking risk for the sector but warrants individual claim-level analysis before drawing FTO conclusions.
Should your audio product team run an FTO against US9609424B2?
Any company developing personalised hearing features — including adaptive EQ, biometric audio calibration, hearing profile generation, or device-specific sound optimisation — should assess residual exposure under US9609424B2. While the Federal Circuit’s affirmance of the invalidity ruling reduces risk for claims that were cancelled, the precise scope of surviving claims, if any, and the existence of related family patents mean that a product-level FTO cannot be skipped. This is particularly relevant for manufacturers of hearables, true wireless earbuds, hearing augmentation devices, and smartphone audio systems.

Invalidity affirmances raise the bar for PAE appeals in audio tech
When the Federal Circuit affirms an invalidity or cancellation ruling, it signals that the claim set failed under rigorous scrutiny. Patent assertion entities holding audio personalisation patents should audit their portfolios for similar claim vulnerabilities before initiating or escalating enforcement campaigns against large consumer electronics manufacturers.
Samsung’s defence playbook: IPR and cancellation as first-line tools
Samsung’s successful defence — upheld at the Federal Circuit — is consistent with the broader industry trend of using post-grant validity challenges as the primary counter to PAE assertions. Companies facing personalised hearing patent claims should evaluate whether inter partes review or cancellation proceedings offer a more efficient resolution path than district court litigation.
Staton v Samsung — key questions answered
The Federal Circuit affirmed the lower tribunal’s ruling in Case 23-2335 on 9 October 2025. The court found no reversible error in the patentability determination — an invalidity or cancellation action — targeting US9609424B2, Staton Techiya’s personalized hearing patent. Samsung prevailed on appeal.
US9609424B2 (application US15/144741) protects methods and devices for personalized hearing — adaptive audio processing tailored to individual user hearing profiles. It was asserted against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc., likely because Samsung’s consumer audio products implement features that Staton Techiya alleged fell within the patent’s claims. The underlying action was an invalidity or cancellation proceeding.
An affirmance of an invalidity or cancellation ruling means the claims targeted in the lower proceeding were found unpatentable and that finding was upheld. To the extent those claims are cancelled, US9609424B2’s enforceability is correspondingly reduced. Staton Techiya cannot reassert cancelled claims against Samsung or any other party. Surviving claims, if any, may retain enforceability, warranting a claim-level FTO review.
After a Federal Circuit affirmance, the only remaining avenue is a petition for a writ of certiorari to the U.S. Supreme Court. The Supreme Court accepts a very small fraction of patent cases, and invalidity affirmances are rarely granted review absent a circuit split or significant legal question. As of the public record, no such petition has been filed.
