Adaptive Avenue Associates v. Mattress Firm: Dismissed With Prejudice in 134 Days
Adaptive Avenue Associates asserted US7171629B2 — a patent covering customised access to multiple websites — against Mattress Firm in the Eastern District of Texas. The parties jointly resolved the dispute and secured a with-prejudice dismissal in under five months, closing the door on any re-filing of the same claims.
Fast agreed exit in a website-access patent dispute in E.D. Texas
On 26 September 2023, Adaptive Avenue Associates, Inc. filed an infringement action against Mattress Firm Holding in the Eastern District of Texas (Case No. 2:23-cv-00442), asserting US Patent No. 7,171,629 B2 — a patent directed at systems and methods for customising user access across multiple websites. The accused product was Mattress Firm’s primary e-commerce platform, mattressfirm.com. The plaintiff was represented by David R. Bennett, while Mattress Firm retained Norton Rose Fulbright US LLP out of Houston.
The case closed on 7 February 2024 — just 134 days after filing — when the court granted the parties’ Agreed Motion to Dismiss. The dismissal was entered with prejudice, meaning Adaptive Avenue Associates is permanently barred from asserting the same patent claims against Mattress Firm in any future action. Each party was ordered to bear its own costs, attorneys’ fees, and expenses, consistent with a negotiated exit rather than a court-imposed outcome.
A resolution in under five months is notably swift even for a jurisdiction known for efficient docketing, and suggests the parties reached a private agreement — likely a licence or covenant not to sue — relatively early in the litigation. The with-prejudice nature of the dismissal is the clinching signal: defendants rarely accept that condition without receiving something of value in return. The precise financial or licensing terms remain confidential and are not disclosed in the public record.

Agreed dismissal with prejudice — what the court order means for both parties
Agreed motion signals a private deal, not a court fight
An agreed motion to dismiss is filed jointly by both parties, indicating a negotiated resolution. Unlike a unilateral voluntary dismissal, both sides must consent — a strong signal that Mattress Firm received something of value (a licence, settlement payment, or covenant not to sue) before agreeing to the with-prejudice condition. The court’s role was purely administrative: review and grant.
Bilateral — both parties consentedWith prejudice: Adaptive Avenue’s claims are permanently extinguished
A dismissal with prejudice operates as a final adjudication on the merits. Adaptive Avenue Associates cannot refile US7171629B2 infringement claims against Mattress Firm in any US federal court. This is a meaningful concession by the plaintiff, typically exchanged for a licence fee or lump-sum settlement. It provides Mattress Firm with lasting legal certainty on this specific patent and these specific claims.
Permanent bar on re-filingEach party bears its own costs — a clean break
The court ordered that each party bear its own costs, expenses, and attorneys’ fees. This is a standard term in negotiated dismissals and avoids any finding of exceptionality under 35 U.S.C. § 285. Neither party is declared a prevailing party for cost purposes, consistent with a confidential settlement where the financial terms are embedded in the private agreement rather than the court order.
No § 285 fee awardEastern District of Texas — a favoured forum for patent assertion
The Eastern District of Texas remains one of the most frequently selected venues for patent infringement actions in the US, particularly by non-practising entities. Filing here signals a plaintiff experienced in patent assertion strategy. The case’s rapid closure suggests Mattress Firm’s counsel at Norton Rose Fulbright moved quickly to assess and neutralise the threat before costly discovery commenced.

Stipulation of dismissal — official text
The court’s order is brief and purely administrative — it recites the parties’ agreement and grants dismissal without any substantive ruling on validity, infringement, or claim construction. The phrase ‘the case has been resolved’ in the agreed motion confirms a private arrangement exists, but its terms are entirely absent from the public record. The with-prejudice condition and mutual cost-bearing are the only judicially enforceable outputs, giving Mattress Firm permanent protection on these claims while leaving the broader patent alive against other defendants.
US7171629B2 — Customising User Access Across Multiple Websites
US Patent No. 7,171,629 B2 (application no. US10/014929) covers systems and methods for customising a user’s access to a plurality of websites. At its core, the patent addresses how a single platform or interface can manage, personalise, or gate access across multiple web domains — a technical problem highly relevant to the era of portal-style internet architecture and one that maps readily onto modern personalisation and multi-brand e-commerce infrastructure. The application predates the era of cloud-native retail platforms, giving its claims a foundational character that can read broadly on contemporary implementations.
For the retail and e-commerce sector, US7171629B2 represents a category of web-infrastructure patent that is difficult to design around without fundamental changes to how multi-domain personalisation is delivered. Any operator running multiple branded storefronts under a common authentication or personalisation layer — a common pattern in omnichannel retail — could plausibly fall within the claim scope. The patent’s assertion against Mattress Firm, a large single-brand but multi-platform retailer, suggests the plaintiff interprets the claims broadly enough to encompass standard retail web architectures.
Should your product team run an FTO against US7171629B2?
If your organisation operates an e-commerce platform, a multi-brand web presence, or any system that customises user access across more than one website or domain, US7171629B2 warrants a freedom-to-operate review. The claims were viable enough to prompt a rapid, with-prejudice settlement from a major national retailer with sophisticated IP counsel. That outcome alone is a credible signal that the patent holder views its claims as commercially enforceable. Waiting for a demand letter is the most expensive form of FTO analysis.

What this case signals for the web-access and e-commerce IP landscape
A rapid, with-prejudice exit in E.D. Texas suggests Mattress Firm treated this as a business risk to be priced and resolved — not litigated.
E-commerce platforms remain targets for multi-website access patents
US7171629B2 targets the architecture of how websites personalise or customise access across multiple domains — a capability embedded in virtually every modern retail platform. Any retailer operating multiple web properties or personalised digital storefronts should treat this patent family as a live monitoring priority, regardless of this case’s resolution.
Speed of resolution is the clearest signal of a licensing settlement
134 days is extremely fast for a patent infringement action. Cases that settle pre-discovery typically do so because the defendant’s legal team quickly calculates that the cost of a licence is lower than the cost of litigation. The with-prejudice condition confirms Mattress Firm secured permanent protection — likely at a negotiated price point well below projected litigation spend.
Adaptive v Mattress — key questions answered
The case was dismissed with prejudice on 7 February 2024 by agreed motion of both parties. The court found the case had been resolved and ordered each party to bear its own costs and attorneys’ fees. Adaptive Avenue Associates cannot refile the same patent claims against Mattress Firm.
Adaptive Avenue asserted US Patent No. 7,171,629 B2 (application no. US10/014929), which covers systems and methods for customising user access across a plurality of websites. The accused product was Mattress Firm’s website, mattressfirm.com.
The case resolved in 134 days — well below the typical median for E.D. Texas patent litigation. The agreed, with-prejudice nature of the dismissal strongly suggests the parties reached a private licensing or settlement agreement before substantive discovery commenced. The exact terms are not disclosed in the public record.
A dismissal with prejudice is a permanent bar. Adaptive Avenue Associates cannot assert the same US7171629B2 claims against Mattress Firm in any future US federal court action. It operates as a final adjudication on the merits of those claims between these specific parties, though the patent remains enforceable against other defendants.
The patent remains active and enforceable against parties other than Mattress Firm. The rapid settlement suggests the plaintiff views the claims as commercially viable. E-commerce operators with multi-domain or multi-brand web architectures that customise user access should consider an FTO analysis against this patent and its related family members as a precautionary measure.
