AAVN v. Welspun: Thread Count Textile Patents Dismissed After Settlement
AAVN, Inc. and Nextt Affiliated, Inc. filed suit against Welspun Global Brands and Welspun USA in the Delaware District Court, asserting two patents covering proliferated thread count woven textile technology. After patent infringement claims were dismissed with prejudice in February 2024, the parties resolved all remaining thread count misrepresentation claims by stipulated dismissal 643 days after filing.
Thread Count Patent Dispute Ends in Bilateral Dismissal
On July 14, 2023, AAVN, Inc. filed a complaint for patent infringement and declaratory judgment in the District of Delaware against Welspun Global Brands Limited and Welspun USA, Inc. An amended complaint was filed on October 2, 2023, adding Nextt Affiliated, Inc. as a plaintiff and asserting infringement of US9131790B2 and US10808337B2, both directed to proliferated thread count woven textile manufacturing. The amended complaint also included alternative thread count misrepresentation claims under Counts 5–8.
On February 5, 2024 — less than seven months after filing — all patent infringement claims (Counts 1–4) were dismissed with prejudice, and Welspun’s patent counterclaims were simultaneously dismissed without prejudice. The parties ultimately resolved the remaining thread count misrepresentation claims through a stipulated dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), with those claims also dismissed with prejudice and no costs awarded to either side.
The case resolved in 643 days, though the substantive patent dispute was effectively concluded within seven months. The early dismissal with prejudice of the patent infringement claims suggests the parties likely reached a commercial arrangement or identified a dispositive legal or factual issue before full discovery. The public record does not disclose the terms of any underlying settlement or licence agreement, and the without-prejudice dismissal of Welspun’s counterclaims preserves their theoretical ability to re-litigate patent validity separately.

With-prejudice dismissal: what the stipulated order means for both parties
Rule 41 stipulated dismissal — what it means in practice
A dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii) requires the written consent of all parties and takes effect immediately upon filing. Because the patent infringement claims and the remaining thread count claims were each dismissed with prejudice, neither set of claims can be re-filed in federal court. Welspun’s patent counterclaims were carved out and dismissed without prejudice, meaning they survive for potential future use.
Rule 41(a)(1)(A)(ii) stipulationPlaintiffs relinquish all patent and misrepresentation claims
AAVN and Nextt Affiliated have permanently surrendered their infringement claims on US9131790B2 and US10808337B2 as well as the thread count misrepresentation claims. A with-prejudice dismissal bars any future action on the same claims against the same defendants. Whether this reflects a confidential licence, a commercial settlement payment, or simply a decision to abandon litigation is not disclosed in the public record.
Claims extinguished with prejudiceWelspun exits with counterclaims intact for future use
Welspun’s patent-related counterclaims — dismissed without prejudice — were not adjudicated on the merits. This preserves Welspun’s optionality: they could, in principle, reassert validity or invalidity arguments in a future proceeding if AAVN’s patents are asserted against other parties. The no-costs stipulation suggests a balanced negotiation rather than a clear-cut win for either side.
Counterclaims dismissed w/o prejudiceThread count patent enforceability remains unresolved publicly
Because neither US9131790B2 nor US10808337B2 was adjudicated on validity or infringement, the patents remain formally in force. Any other textile manufacturer operating in the proliferated thread count woven fabric space faces an unresolved IP risk from these patents. The early resolution of infringement claims — before claim construction — means no judicial interpretation of the patent scope has been published.

Official order — verbatim text
The stipulated dismissal is framed in two sequential layers: patent infringement claims (Counts 1–4) and Welspun’s counterclaims were resolved on February 5, 2024, followed by the thread count misrepresentation claims via the final stipulation. The explicit with-prejudice designation on plaintiffs’ claims forecloses any future federal action on these patents against these defendants. The without-prejudice carve-out for Welspun’s counterclaims is strategically significant — it preserves invalidity arguments that were never tested, leaving the patents’ legal status commercially ambiguous.
US9131790B2 & US10808337B2 — Proliferated Thread Count Woven Textile Technology
US9131790B2 (application No. US14/185942) and US10808337B2 (application No. US16/120216) both protect technology enabling proliferated thread count in woven textiles through the simultaneous insertion of multiple adjacent parallel yarns within a single pick insertion event on a loom apparatus, drawn from a multi-pick yarn package. This approach allows manufacturers to achieve higher thread counts without conventional multi-pass weaving, which is commercially significant in the premium bedding and home textile sector.
In a market where thread count is a primary consumer quality signal, patents covering methods to achieve elevated thread counts through novel loom techniques carry substantial commercial weight. Welspun, as one of the world’s largest home textile suppliers, would be a high-value enforcement target. The fact that infringement claims were resolved pre-claim construction suggests either a licensing resolution or a mutual recognition that litigation risk outweighed potential damages — but the patents remain unadjudicated and enforceable against other industry participants.
Should you run an FTO against US9131790B2 and US10808337B2?
Any manufacturer, brand, or retailer involved in producing or sourcing woven textiles marketed on the basis of elevated thread counts — particularly those using multi-pick insertion loom technology — should assess freedom-to-operate against these two patents. The claims were never construed by a court, meaning scope uncertainty is high. The without-prejudice dismissal of Welspun’s invalidity counterclaims confirms that no public prior art record was developed in this case.
PatSnap Eureka’s FTO Search Agent can map your woven textile manufacturing processes against the claim language of US9131790B2 and US10808337B2, surface relevant prosecution history, identify potential design-arounds, and flag any related AAVN portfolio filings. Given the dual-patent assertion strategy used in this case, a portfolio-level clearance review is advisable rather than a single-patent analysis.

What this case signals for the textile IP and thread count patent landscape
This bilateral dismissal leaves two live patents and no court guidance on scope — a situation that demands proactive FTO analysis from textile manufacturers.
Early dismissal before claim construction limits public guidance
The patent infringement claims were dropped within seven months, before any Markman hearing or claim construction order. This means no judicial record defines the scope of US9131790B2 or US10808337B2. Competitors and licensees in the thread count textile space must rely entirely on prosecution history and USPTO records to assess risk exposure.
No-costs award signals a negotiated exit, not capitulation
A mutual no-costs dismissal is typically inconsistent with one side simply walking away defeated. The structure — with plaintiffs’ claims dismissed with prejudice and defendants’ counterclaims dismissed without prejudice — suggests a carefully balanced resolution, possibly including undisclosed commercial terms between a patent licensor and a major global textile supplier.
Aavn v Welspun — key questions answered
AAVN and Nextt Affiliated asserted two patents: US9131790B2 and US10808337B2. Both cover proliferated thread count woven textile technology achieved through simultaneous insertion of multiple parallel yarns in a single pick insertion event using a multi-pick yarn package loom apparatus.
The public record does not disclose the specific reason the patent infringement claims (Counts 1–4) were dismissed with prejudice on February 5, 2024. The timing — before claim construction — suggests the parties may have reached a private licensing or commercial arrangement, or identified a dispositive issue, but no court order explaining the basis has been published.
The plaintiffs’ patent infringement and thread count misrepresentation claims were dismissed with prejudice, permanently barring re-filing of those claims. Welspun’s patent counterclaims were dismissed without prejudice, meaning Welspun retains the right to assert those arguments — including potential invalidity positions — in future proceedings if the patents are asserted again.
Yes. A stipulated dismissal does not invalidate or limit a patent’s claims. Because no claim construction or validity ruling was issued, US9131790B2 and US10808337B2 remain in force and enforceable against other parties in the woven textile industry. Any competitor using multi-pick yarn package insertion technology should assess FTO risk independently.
Counts 5–8 of the amended complaint asserted causes of action arising from Welspun’s alleged misrepresentation of thread count in its textile products. These non-patent claims were ultimately dismissed with prejudice as part of the final stipulated dismissal, consistent with the parties having resolved all outstanding disputes. The specific legal theories and factual allegations underlying these counts are not further detailed in the public termination record.
