Adaptive Avenue v. Petco: Web Auto-Composition Patents Dismissed With Prejudice
Adaptive Avenue Associates filed a patent infringement action against Petco Animal Supplies in the Western District of Texas, asserting two patents covering methods for auto-composing websites. The case ended by joint stipulation of dismissal with prejudice under Rule 41(a)(1)(A)(ii) — 144 days after filing, with each party bearing its own costs.
Early stipulated exit: both sides walk away cleanly on web patent claims
On April 4, 2025, Adaptive Avenue Associates, Inc. filed a patent infringement action against Petco Animal Supplies Stores, Inc. in the U.S. District Court for the Western District of Texas (Case No. 7:25-cv-00153). The suit alleged infringement of two issued patents — US7171629B2 and US7428707B2 — through Petco’s operation of www.petco.com, specifically targeting Petco’s use of an auto-composition method for assembling its website.
On August 24, 2025, the parties filed a Joint Stipulation of Dismissal, which the Court granted the same day. Under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), such a stipulation signed by all appearing parties takes effect automatically upon filing and requires no judicial approval. The Court ordered the action closed with all claims dismissed with prejudice — meaning Adaptive Avenue is permanently barred from reasserting the same claims against Petco in any future action. Each party was ordered to bear its own attorney fees and costs, a symmetrical cost disposition consistent with a negotiated exit.
The 144-day lifespan of this case — from filing to dismissal — is relatively compressed for patent litigation, and the with-prejudice designation combined with mutual cost-bearing typically signals that the parties reached some form of private resolution, though the public record is silent on whether any license, payment, or other commercial term was exchanged. The absence of claim construction proceedings, dispositive motions, or trial activity in the docket suggests the matter was resolved before substantive litigation commenced.
Filing to Dismissed with Prejudice in 144 days
144 days — below the median time-to-termination for W.D. Texas patent cases, suggesting early resolution
Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii): automatic dismissal by joint stipulation
A Rule 41(a)(1)(A)(ii) stipulated dismissal takes effect automatically upon filing — no judicial approval is required. Both parties signed, making the dismissal self-executing. The Fifth Circuit confirmed this in Yesh Music v. Lakewood Church (2013), cited by the Court. This is the fastest procedural exit available in federal civil litigation, typically deployed when parties have already reached a private resolution.
Procedural exit — no merits adjudicationWith prejudice: Adaptive Avenue cannot refile these claims against Petco
A dismissal with prejudice operates as a final adjudication on the merits under res judicata principles. Adaptive Avenue Associates is permanently barred from asserting the same patent claims — under US7171629B2 and US7428707B2 — against Petco in any subsequent action. This is a significant concession by the plaintiff, and while the underlying commercial terms are not in the public record, the with-prejudice designation typically reflects either a licensing deal or a strategic decision to abandon the claim.
Plaintiff — claims permanently extinguishedPetco secures finality — but each party bears its own costs
Petco obtains a permanent bar against these specific patent claims without a court ruling on the merits of infringement or validity. The mutual cost-bearing order means neither side recovered attorney fees — a departure from the fee-shifting that might follow an ‘exceptional case’ finding under 35 U.S.C. § 285. For Petco, this closes the litigation cleanly while leaving the underlying patents valid and potentially asserted against other defendants.
Defendant — no fee recovery, full finalityPatents survive — other e-commerce operators remain exposed
The dismissal with prejudice resolves only the Petco dispute. US7171629B2 and US7428707B2 remain issued and enforceable, and Adaptive Avenue retains the right to assert them against other web operators using auto-composition methods. Companies in retail e-commerce and web platform development should treat this resolution as a signal that these patents are being actively enforced, not abandoned.

Official order — verbatim text
The Court’s order confirms a Rule 41(a)(1)(A)(ii) stipulated dismissal with prejudice — a procedurally clean, self-executing exit that required no merits ruling. The ‘with prejudice’ designation is the operative term: it extinguishes Adaptive Avenue’s right to refile these specific claims against Petco under res judicata. The symmetric cost order — each party bearing its own fees — is consistent with a privately negotiated resolution; it forecloses any fee-shifting argument under § 285 and suggests neither party sought to characterise the case as exceptional.
US7171629B2 & US7428707B2 — Web Auto-Composition Method Patents
US7171629B2 (application no. 10/014929) and US7428707B2 (application no. 10/698332) both cover methods in the domain of automated web page composition — the process by which website content, layout, and structure are assembled programmatically rather than manually. These patents sit in the intersection of web architecture and content management, addressing how a system can automatically generate or assemble a coherent website from component parts. The asserted product context — www.petco.com — suggests the patents were applied to dynamic e-commerce site construction.
For the e-commerce sector, patents covering web auto-composition methods represent a meaningful portfolio risk because the underlying techniques are broadly deployed across retail, SaaS, and CMS platforms. Any company using template-driven, rules-based, or AI-assisted page assembly may fall within the scope of these claims. The fact that Adaptive Avenue pursued Petco — a major national retailer — suggests a willingness to target high-traffic commercial websites, and the swift private resolution indicates the portfolio carries enough credible claim scope to prompt early settlement consideration.
Should your team run an FTO analysis against US7171629B2 and US7428707B2?
If your organisation operates an e-commerce platform, content management system, or any web infrastructure that programmatically assembles or composes web pages, these two patents warrant a freedom-to-operate review. The claims as asserted against Petco’s retail website suggest a broad read on automated web composition — a technique foundational to modern e-commerce. Product and engineering teams deploying dynamic page assembly, personalisation engines, or templating frameworks should treat this as a priority FTO item.
PatSnap Eureka’s FTO Search Agent can map your product’s technical implementation against the independent claims of US7171629B2 and US7428707B2, surface relevant prior art that could support an IPR petition, and identify design-around options. Given that neither patent appears to have been challenged at the PTAB, Eureka’s prior art landscape tool can help assess the viability of a pre-emptive validity challenge before a demand letter arrives.

Web auto-composition patents are being actively asserted — map your exposure now
US7171629B2 and US7428707B2 cover methods for automatically composing web pages. Any e-commerce operator, CMS platform, or website builder using algorithmic or templated page assembly should assess whether their implementation falls within the claim scope of these patents before receiving a demand letter.
With-prejudice mutual dismissals often mask undisclosed licensing terms
The combination of a with-prejudice dismissal and symmetric cost-bearing is a classic litigation settlement footprint. Patent counsel monitoring assertion patterns should note this case as a resolved enforcement event — and consider whether a licence was granted, which would inform valuation of the portfolio in future disputes.
Adaptive v Petco — key questions answered
Adaptive Avenue Associates sued Petco in the Western District of Texas on April 4, 2025, asserting infringement of US7171629B2 and US7428707B2 — patents covering web auto-composition methods — through Petco’s operation of www.petco.com. The case was dismissed with prejudice by joint stipulation under Rule 41(a)(1)(A)(ii) on August 26, 2025, after 144 days. Each party was ordered to bear its own attorney fees and costs.
A dismissal with prejudice bars Adaptive Avenue from filing the same patent claims — under US7171629B2 and US7428707B2 — against Petco in any future action. It operates as a final adjudication on the merits for purposes of res judicata. However, the patents remain valid and enforceable against other defendants, and Adaptive Avenue retains the right to assert them in new actions against different parties.
US7171629B2 (App. No. 10/014929) and US7428707B2 (App. No. 10/698332) are U.S. patents covering methods for automatically composing or assembling websites — broadly, techniques by which a system programmatically constructs web pages from component elements. They were asserted against Petco’s e-commerce website, petco.com, suggesting applicability to dynamic or templated retail site construction.
Under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), a stipulation of dismissal signed by all parties who have appeared is self-executing and takes effect automatically upon filing — no court approval is required. The Court cited Fifth Circuit authority (Yesh Music v. Lakewood Church, 727 F.3d 356 (5th Cir. 2013)) confirming this rule, and issued its order closing the case as a ministerial confirmation rather than a substantive ruling.
No. A dismissal with prejudice resolves only the claims between Adaptive Avenue and Petco — it does not adjudicate the validity or enforceability of US7171629B2 or US7428707B2. The patents remain issued and enforceable. The dismissal prevents Adaptive Avenue from re-suing Petco on the same claims, but does not affect the patents’ standing against other potential defendants or their enforceability in future proceedings.
