Nike v. Lululemon Athletica: Federal Circuit Affirms Patent Unpatentable
Nike's US10232220B2, covering fitness monitoring via mobile device, was challenged by Lululemon Athletica and found unpatentable. The Federal Circuit affirmed that ruling in a Rule 36 judgment after 667 days of appellate proceedings, leaving Nike's patent claim extinguished.
Nike's mobile fitness patent extinguished after Federal Circuit affirms
Nike, Inc. brought an appeal before the United States Court of Appeals for the Federal Circuit (Case No. 24-2074) asserting rights in US10232220B2, a patent directed to monitoring fitness using a mobile device. The opposing party was Lululemon Athletica, Inc., represented by Morrison & Foerster LLP. The underlying dispute concerned a patentability challenge — an invalidity or cancellation action — targeting the '220 patent. The appeal was filed on 15 July 2024.
The Federal Circuit issued its disposition on 13 May 2026 under Federal Circuit Rule 36, affirming the finding of unpatentability in a summary judgment without a written opinion. The recorded basis of termination is 'Unpatentable,' and the docket order states the cause was heard, considered, and 'AFFIRMED.' Rule 36 affirmances signal that the appellate panel found no reversible error in the decision below but do not issue a reasoned opinion explaining the specific grounds.
The 667-day appellate duration is consistent with Federal Circuit patent appeal timelines. A Rule 36 affirmance forecloses further argument on the same grounds at this court level. The specific findings underlying the unpatentability determination — and any remaining procedural options Nike may pursue — are not detailed in the available public record.

US10232220B2 — Monitoring fitness using a mobile device
Product teams and IP counsel developing mobile fitness monitoring features — including activity tracking in apps, wearables, or connected health platforms — should note that US10232220B2 has been found unpatentable and that finding has been affirmed by the Federal Circuit. While this patent no longer presents an active enforcement risk, Nike holds a broader portfolio in the fitness technology space. Any FTO assessment should extend to related Nike applications, continuations, and granted patents in mobile health and fitness monitoring.
Official order — verbatim text
The Federal Circuit's Rule 36 order affirms the unpatentability of US10232220B2 without issuing a written opinion, meaning no citable appellate reasoning is generated. The panel's determination that the lower tribunal committed no reversible error is final and binding. For Nike, the patent's claims are extinguished at this level; for Lululemon, the invalidity position is confirmed. The absence of a written opinion is consistent with cases where the appellate panel views the outcome as straightforward on the existing record.
Federal Circuit affirms: what the ruling means for both parties
Rule 36 affirmance: the court found no reversible error below
A Federal Circuit Rule 36 judgment affirms the decision below without a written opinion. The panel determined that no reversible error existed in the unpatentability ruling — meaning the prior decision's reasoning and outcome are left intact. Rule 36 does not generate citable precedent, but the affirmance is a final, binding appellate disposition. Nike's '220 patent claim is extinguished at this appellate stage.
No reversible error foundNike's US10232220B2 loses enforceability after affirmance
For Nike as the patent holder and appellant, the Federal Circuit affirmance confirms the unpatentability finding against US10232220B2. The patent's claims directed to mobile device fitness monitoring cannot be enforced following this ruling. Nike's options for further challenge at this appellate level are exhausted. Any path forward would require a distinct procedural avenue, details of which are not disclosed in the available record.
Patent claims extinguishedLululemon secures confirmation of unpatentability
For Lululemon Athletica, the Federal Circuit's affirmance validates its invalidity or cancellation position against the asserted patent. The '220 patent can no longer be wielded against Lululemon's mobile fitness monitoring activities in connection with this proceeding. The affirmance raises the bar for Nike to reassert equivalent claims in this technology domain, consistent with the estoppel principles that typically accompany final unpatentability determinations.
Invalidity confirmed on appealMobile fitness monitoring IP landscape: enforcement risk reduced
The affirmance of unpatentability for US10232220B2 signals to competitors and product teams operating in the mobile fitness monitoring space that this specific patent no longer presents an enforcement risk. Companies developing fitness tracking features in mobile applications, wearables, or connected devices may take note of the narrowed Nike IP position in this domain. Broader Nike portfolio activity in fitness monitoring technology warrants continued monitoring.

R&D signals in the mobile fitness monitoring IP space
Forward-looking patent and innovation intelligence derived from the Nike v. Lululemon Federal Circuit dispute over mobile fitness tracking technology.
Nike's fitness monitoring portfolio beyond the '220 patent
With US10232220B2 invalidated, the question for competitors and licensees is what Nike's remaining patent estate in mobile fitness and health monitoring looks like. Nike has historically filed broadly in activity tracking, sensor integration, and connected training platforms. Mapping the surviving portfolio reveals where enforcement risk remains and where prosecution gaps may exist.

Mobile fitness monitoring is an active filing domain with contributions from sportswear brands, consumer electronics companies, and digital health platforms. Filing trends around mobile-based activity tracking, biometric data capture, and real-time health feedback reveal which players are building IP positions in the space post-invalidation of the Nike '220 patent.
Fitness monitoring filing trendsLululemon's patent strategy in connected fitness
Lululemon's successful challenge to Nike's '220 patent signals investment in IP defence strategy in the connected fitness space. Assessing Lululemon's own filing activity — including wearable technology, fitness data, and mobile health — reveals whether the company is building offensive IP positions alongside its defensive posture in litigation.
Lululemon IP filing activityClaim territory opened by the invalidation of US10232220B2
The unpatentability of US10232220B2 may open adjacent claim space in mobile fitness monitoring for competitors and new entrants. Analysing the claim scope of the invalidated patent alongside current filing activity helps identify technology sub-areas — such as AI-driven fitness coaching, cross-device activity sync, or real-time biometric feedback — where novel filings may now face reduced blocking risk.

What this case signals for the mobile fitness IP landscape
A Federal Circuit Rule 36 affirmance of unpatentability sends a clear signal to patent holders and challengers in the digital fitness space.
Rule 36 disposals offer no written reasoning — but the outcome is final
Federal Circuit Rule 36 affirmances provide no published opinion for patent holders or third parties to dissect. For competitors and counsel, this means the precise invalidity grounds remain opaque — but the unpatentability of US10232220B2 is conclusively established. IP teams should not rely on silence as ambiguity.
Nike's mobile fitness monitoring IP position requires reassessment
With US10232220B2 extinguished, product teams and counsel tracking Nike's enforcement posture in mobile fitness should audit Nike's remaining portfolio in this domain. The loss of this patent does not foreclose Nike from asserting related or continuation claims, and monitoring filing activity is advised for companies active in connected fitness.
Nike v Lululemon — key questions answered
The Federal Circuit affirmed the finding of unpatentability against Nike's US10232220B2 covering mobile fitness monitoring. The affirmance was issued under Federal Circuit Rule 36 on 13 May 2026, without a written opinion. The recorded basis of termination is 'Unpatentable.'
A Rule 36 affirmance means the Federal Circuit panel found no reversible error in the lower tribunal's unpatentability determination and affirmed without issuing a written opinion. The ruling is final and binding at this appellate level. US10232220B2 is no longer enforceable following this disposition. Rule 36 judgments do not generate citable precedent.
The patent at issue was US10232220B2 (application number US15/727984), directed to monitoring fitness using a mobile device. The underlying dispute was classified as an invalidity or cancellation action challenging the patentability of the '220 patent's claims.
For Lululemon, the Federal Circuit's affirmance confirms that the invalidity position it pursued against US10232220B2 has succeeded at the highest available appellate level in this proceeding. The patent can no longer be asserted against Lululemon in connection with this action. The specific prior art or claim construction grounds underlying the finding are not detailed in the available public record.
The invalidation of US10232220B2 removes one specific enforcement instrument from Nike's portfolio in mobile fitness monitoring. However, Nike's broader patent estate in fitness technology, activity tracking, and connected health remains active. Companies developing similar products should conduct a current FTO review against Nike's full portfolio rather than relying solely on the extinguishment of the '220 patent.
