Barrday v. Lincoln Fabrics: Federal Circuit Affirms Unpatentability of Securing Yarn Patents
Barrday Corporation appealed a finding of unpatentability for two securing yarn patents — US9127379B2 and US8573261B2 — against Lincoln Fabrics Inc. The Federal Circuit affirmed the lower decision in a 520-day appeal, leaving both patents without enforceable protection.
Federal Circuit closes the door on Barrday's securing yarn patent claims
Barrday Corporation, asserting rights in two patents covering securing yarn technology — US9127379B2 and US8573261B2 — brought an infringement action against Lincoln Fabrics Inc. The dispute reached the Court of Appeals for the Federal Circuit under Case No. 22-1903, filed on 14 June 2022 and closed on 16 November 2023.
The Federal Circuit affirmed the decision below. The recorded basis of termination is 'Unpatentable,' and the docket order states the cause was ordered and adjudged 'AFFIRMED.' This means the lower tribunal's finding that the asserted patents are unpatentable was upheld on appeal, leaving Barrday without patent protection on the two asserted securing yarn patents vis-à-vis Lincoln Fabrics.
The 520-day appellate timeline is consistent with standard Federal Circuit review periods for patent validity appeals. The specific arguments raised on appeal and the underlying invalidity grounds are not detailed in the available record. What is clear is that the affirmance forecloses further challenge at this appellate level on the same grounds, materially weakening Barrday's ability to assert these particular patents against Lincoln Fabrics or similarly positioned competitors.

US9127379B2 & US8573261B2 — Securing Yarn Technology
While both patents have been found unpatentable by the Federal Circuit in this proceeding, R&D teams and product managers working with securing yarn constructions in technical textiles should not assume blanket freedom to operate without independent analysis. Related family members, continuation applications, or divisional patents may still be active and enforceable. Any commercial product incorporating securing yarn technology that competes with Barrday's portfolio warrants a targeted FTO review.
Official order — verbatim text
The Federal Circuit's order — 'ORDERED AND ADJUDGED: AFFIRMED' — is a merits affirmance confirming that the lower tribunal's unpatentability determination contained no reversible error. Under the appellate standard of review applicable to patent validity, legal conclusions are reviewed de novo and factual findings for clear error. The affirmance signals that neither standard yielded grounds to disturb the outcome below, leaving both US9127379B2 and US8573261B2 unpatentable.
Federal Circuit affirms: what the ruling means for both parties
What 'AFFIRMED' means at the Federal Circuit
An affirmance by the Federal Circuit means the appellate panel found no reversible error in the decision below. The lower tribunal's determination that the asserted patents are unpatentable is now upheld with the full authority of the Federal Circuit. Barrday's appellate arguments were not sufficient to disturb that finding. The patents remain unenforceable as adjudicated.
No reversible error foundBarrday loses enforceability on both asserted patents
With the unpatentability finding affirmed, Barrday Corporation cannot enforce US9127379B2 or US8573261B2 against Lincoln Fabrics on the basis of this litigation. The affirmance effectively neutralises both patents as enforcement tools, at least as against this defendant, and raises the bar for any future assertion strategy relying on these specific claims.
Patent enforceability lostLincoln Fabrics' invalidity position is judicially confirmed
Lincoln Fabrics has secured an affirmed finding of unpatentability against both asserted patents, exhausting Barrday's appellate options at this level. The Federal Circuit affirmance strengthens Lincoln Fabrics' freedom to operate in the securing yarn technology space without risk of infringement liability under these two specific patents. Further challenge to this outcome would require Supreme Court review.
Appellate options exhaustedSecuring yarn IP landscape shifts after affirmance
The invalidation of two securing yarn patents at the Federal Circuit level suggests heightened scrutiny of patent claims in this textile technology domain. Competitors and manufacturers working with securing yarn constructions may find the prior art landscape broader than Barrday's filings suggested. Companies with similar granted claims should assess exposure to unpatentability challenges informed by this outcome.

R&D signals in the securing yarn and technical textiles IP space
Forward-looking patent intelligence derived from Barrday v. Lincoln Fabrics — tracking portfolio activity, technology trends, and white space in securing yarn and performance textile innovation.
Barrday's broader securing yarn and textile patent activity
With two securing yarn patents now invalidated, Barrday's remaining portfolio in this technology domain warrants close monitoring. Analysing Barrday's prosecution history, continuation filings, and related granted patents can reveal whether alternative claim strategies are being pursued to re-establish IP coverage in securing yarn technology.
Portfolio monitoringPatent filing trends in securing yarn and structural textile constructions
The invalidation of Barrday's securing yarn patents suggests prior art in this domain is well-developed. Mapping recent filing trends by assignees active in securing yarns, woven structural textiles, and performance fabrics can reveal which technical approaches remain protectable and where innovation is concentrating.
Filing trend analysisLincoln Fabrics' patent position in technical textiles
Lincoln Fabrics successfully defended an unpatentability finding through Federal Circuit affirmance. Understanding Lincoln Fabrics' own IP filing activity and freedom-to-operate posture in securing yarn and woven textile technologies can inform competitive strategy for other players in the performance fabrics space.
Competitor intelligenceNovel claim strategies in securing yarn technology post-invalidation
The invalidation of US9127379B2 and US8573261B2 clears prior claim coverage in specific securing yarn constructions. R&D teams can identify adjacent technical approaches — such as novel yarn integration methods, coating technologies, or composite securing structures — that may still support patentable differentiation in this evolving space.

What this case signals for the technical textiles IP landscape
A Federal Circuit affirmance of unpatentability in securing yarn technology reshapes enforcement risk and portfolio strategy across the technical textiles sector.
Both Barrday securing yarn patents are now judicially unenforceable
US9127379B2 and US8573261B2 have been found unpatentable and that finding affirmed. Any current or planned licensing or enforcement strategy built on these patents requires immediate reassessment. Companies that received demand letters or licences under these patents should consult counsel on the implications.
Federal Circuit affirmance raises the prior art ceiling in securing yarns
An affirmed unpatentability finding signals that the prior art or other invalidity grounds in this technology space are robust. R&D teams developing novel yarn securing technologies should review the prior art record surfaced in this case to understand where genuinely patentable differentiation still exists.
Barrday v LINCOLN — key questions answered
The Federal Circuit affirmed the lower tribunal's finding in Case No. 22-1903. The recorded basis of termination is 'Unpatentable,' and the docket order states the case was 'AFFIRMED.' Both asserted patents — US9127379B2 and US8573261B2 — were found unpatentable, with that finding upheld on appeal.
Barrday asserted two patents: US9127379B2 (application no. US14/070798) and US8573261B2 (application no. US13/565856). Both relate to securing yarn technology in the technical textiles domain. Both were found unpatentable, and the Federal Circuit affirmed that determination.
The affirmance confirms that US9127379B2 and US8573261B2 are unpatentable, eliminating their enforceability in this dispute. Barrday cannot pursue Lincoln Fabrics under these patents following the affirmance. Further appellate options at the Federal Circuit level are exhausted; any further review would require Supreme Court certiorari.
The dispute centred on securing yarns — a specialised category of technical textile components. The two asserted patents both addressed securing yarn technology, and the infringement action was filed in the context of this product area.
The appeal ran for 520 days, filed on 14 June 2022 and closed on 16 November 2023. This duration is broadly consistent with standard Federal Circuit review timelines for patent validity appeals involving technical textile subject matter.
