Adaptive Avenue Associates v. Northern Tool & Equipment: Website Customization Patent Dispute Ends in Stipulated Dismissal
Adaptive Avenue Associates asserted two patents covering methods for customizing access to multiple websites against Northern Tool & Equipment’s northerntool.com platform. The case, filed in the Eastern District of Texas, ended after 174 days via a stipulated dismissal — with plaintiff’s claims dropped with prejudice and defendant’s counterclaims dismissed without prejudice as moot.
Website customization patent dispute resolved by stipulated dismissal in E.D. Tex.
Adaptive Avenue Associates, Inc. filed suit against Northern Tool & Equipment Co. on June 12, 2025 in the Eastern District of Texas (Case No. 4:25-cv-00632), before Judge Sean D. Jordan. The complaint alleged infringement of US7171629B2 and US7428707B2 — patents covering methods for customizing user access to multiple websites — as practised through northerntool.com, Northern Tool’s e-commerce platform.
The case closed on December 3, 2025 via a joint stipulation of dismissal under Fed. R. Civ. P. 41(a)(1)(A)(ii) and (c). Plaintiff’s claims were dismissed with prejudice — meaning Adaptive Avenue is permanently barred from reasserting the same claims against Northern Tool on these patents. Northern Tool’s counterclaims were dismissed without prejudice as moot, preserving the defendant’s ability to revive those counterclaims if circumstances change.
A 174-day lifecycle suggests the parties reached resolution before significant merits litigation, consistent with early-stage settlement or licensing negotiations. The with-prejudice dismissal of plaintiff’s claims is the commercially significant term: it forecloses future assertion against this defendant. The public record does not disclose any financial consideration, licensing terms, or the trigger for settlement, leaving the broader monetisation strategy of Adaptive Avenue’s portfolio uncertain.

Stipulated dismissal: what the with-prejudice terms mean for each party
Rule 41 stipulated dismissal — a bilateral procedural exit
Under Fed. R. Civ. P. 41(a)(1)(A)(ii), both parties jointly stipulate to end the case without a court ruling on the merits. Rule 41(c) extends the same framework to counterclaims. This mechanism requires no judicial approval and takes effect upon filing, making it the fastest route to case termination. It does not constitute an admission of liability by either party.
No merits adjudicationWith prejudice for plaintiff; without prejudice for defendant — an asymmetric outcome
Adaptive Avenue’s claims were dismissed with prejudice, permanently barring reassertion of these patent claims against Northern Tool. Northern Tool’s counterclaims — which may have included invalidity or non-infringement defences — were dismissed without prejudice as moot, meaning they were never litigated on the merits and could theoretically be revived in a new action if a new dispute arises.
Plaintiff permanently barredAdaptive Avenue forfeits further action against Northern Tool on these patents
The with-prejudice dismissal is a significant concession by the plaintiff. Adaptive Avenue cannot bring these same patent claims against Northern Tool again. Whether this reflects a confidential licence, a monetisation ceiling, or an assessment of litigation risk is not disclosed in the public record. The outcome suggests the plaintiff did not obtain a court-validated finding of infringement.
No reassertion rightsNorthern Tool exits cleanly with moot counterclaims preserved
Northern Tool secured the with-prejudice bar against future assertion by Adaptive Avenue on these two patents. Its counterclaims — potentially including invalidity challenges — remain unresolved on the merits, which means the patents themselves survive without a validity ruling. Fish & Richardson’s involvement as defence counsel suggests Northern Tool invested in a robust litigation posture that may have contributed to the early resolution.

Official order — verbatim text
The stipulation’s language is precise in its asymmetry: plaintiff’s claims are dismissed ‘WITH PREJUDICE’ while defendant’s counterclaims are dismissed ‘WITHOUT PREJUDICE AS MOOT.’ The ‘as moot’ qualifier indicates Northern Tool’s counterclaims were never adjudicated — their dismissal reflects only that there is no live controversy to resolve, not any finding on validity or non-infringement. Critically, no court made a ruling on the merits of either party’s substantive positions.
US7171629B2 & US7428707B2 — Website customization access methods
US7171629B2 (application no. 10/014929) and US7428707B2 (application no. 10/698332) are method patents covering techniques for customising access to a plurality of websites. Filed in the early 2000s, these patents sit within the broader domain of web personalisation — an area that grew rapidly during the commercialisation of consumer internet infrastructure. The claimed methods relate to how users interact with and navigate across multiple web properties, a function central to e-commerce platform architectures.
These patents’ strategic value lies in their breadth of application across any e-commerce or multi-site web operator. With northerntool.com identified as the accused instrumentality, the assertion appears to target standard website personalisation and access-management functionality. In an era of heightened § 101 scrutiny, method claims directed to abstract processes of organising or customising web access face meaningful Alice/Mayo eligibility challenges — a factor likely central to any invalidity defence strategy in this case.
Should your e-commerce platform run an FTO against US7171629B2 and US7428707B2?
Any company operating a multi-site e-commerce platform, customer portal, or website personalisation engine should assess exposure to these patents. The claims cover methods for customising access to multiple websites — functionality embedded in virtually every modern retail web stack. The fact that Adaptive Avenue pursued Northern Tool suggests an active monetisation programme targeting this space.

What this case signals for the website customization IP landscape
A rapid with-prejudice exit in E.D. Tex. carries specific implications for e-commerce operators and patent assertion entities in the web technology space.
With-prejudice dismissal limits but does not extinguish portfolio risk
The dismissal forecloses Northern Tool specifically but leaves the underlying patents — US7171629B2 and US7428707B2 — intact and potentially assertable against other e-commerce platforms. Other retailers operating website personalisation or multi-site access systems should monitor Adaptive Avenue’s assertion activity closely.
Early resolution in E.D. Tex. suggests leverage rather than litigation strength
Cases resolving in under 180 days in the Eastern District of Texas typically do so before claim construction, which is often the first major merits checkpoint. This timeline suggests the case may have been driven by licensing pressure rather than a strong infringement read, though the public record does not confirm this.
Adaptive v Northern — key questions answered
It means Adaptive Avenue permanently relinquished its right to sue Northern Tool again on US7171629B2 and US7428707B2. A with-prejudice dismissal under Rule 41 is a final disposition against the plaintiff — no new action on the same claims can be filed against the same defendant. Northern Tool’s counterclaims were dismissed without prejudice as moot, preserving them for potential future use.
Adaptive Avenue asserted two patents: US7171629B2 (application no. 10/014929) and US7428707B2 (application no. 10/698332). Both patents cover methods for customising user access to a plurality of websites. The accused product was northerntool.com, Northern Tool’s e-commerce platform.
The 174-day resolution is below typical Eastern District of Texas patent case timelines, which suggests the parties reached agreement before claim construction or significant merits briefing. This timeline is consistent with early-stage licensing negotiations or a defendant posture that made continued litigation unattractive for the plaintiff. The public record does not confirm whether any financial consideration changed hands.
Northern Tool’s counterclaims — likely including invalidity or non-infringement positions — were dismissed without prejudice as moot because they became irrelevant once plaintiff’s claims were dropped. ‘As moot’ means no merits ruling was made. The patents therefore survive without a court ruling on their validity, which preserves Adaptive Avenue’s ability to assert them against other parties.
Northern Tool was represented by Fish & Richardson PC (Dallas office), with attorneys Brandon Scott Avers, Lance Eric Wyatt Jr., Michael Alden Vincent, and Neil J. McNabnay on record. Fish & Richardson is a specialist IP litigation firm with significant experience in patent defence, which suggests Northern Tool mounted a substantive litigation response before the case settled.
