Push Data LLC v. Pacific Sunwear — Four-Patent Mobile App Suit Dismissed With Prejudice
Push Data LLC filed a four-patent infringement action against Pacific Sunwear of California in the Eastern District of Texas, targeting the PacSun mobile app and rewards platform. Before Pacific Sunwear filed any answer, Push Data voluntarily dismissed the case with prejudice under Rule 41(a)(1)(A)(i) — ending all claims in just 110 days.
Four-patent mobile data suit ends before PacSun files a single answer
On 14 February 2024, Push Data LLC filed a patent infringement action against Pacific Sunwear of California LLC in the U.S. District Court for the Eastern District of Texas before Judge Amos L. Mazzant. The complaint asserted four U.S. patents — US7292844B2, US7058395B2, US6983139B2, and US7212811B2 — against the PacSun iOS and Android mobile applications and the PacSun Rewards loyalty platform. The patents relate to mobile data delivery and push notification-style communication technologies.
The case closed on 3 June 2024, just 110 days after filing. Push Data invoked Federal Rule of Civil Procedure 41(a)(1)(A)(i), which permits a plaintiff to dismiss without court order before the defendant has served an answer. Pacific Sunwear had not yet answered, so the notice was self-executing. Critically, Push Data chose to dismiss with prejudice — meaning the claims are extinguished and cannot be reasserted against Pacific Sunwear on these patents.
The speed and pre-answer timing of the dismissal is notable. Cases that resolve before an answer is filed typically suggest either a negotiated resolution reached off the record, a strategic reassessment by plaintiff’s counsel, or a decision not to pursue litigation costs against this particular defendant. The public record is silent on whether any monetary consideration changed hands. The with-prejudice election, however, is a meaningful concession by Push Data that forecloses any future enforcement action against Pacific Sunwear on these four patents.

Dismissed with prejudice: what Rule 41 closure means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s right to exit before answer
Federal Rule of Civil Procedure 41(a)(1)(A)(i) allows a plaintiff to dismiss an action unilaterally — without court approval — provided the defendant has not yet served an answer or motion for summary judgment. Push Data filed its notice before Pacific Sunwear answered, making the dismissal self-executing. The critical variable here is the with-prejudice election: unlike a without-prejudice dismissal, this cannot be refiled.
Pre-answer voluntary dismissalWith prejudice: Push Data extinguishes its own claims
Push Data expressly dismissed with prejudice, which operates as a final adjudication on the merits for res judicata purposes. This forecloses any future infringement suit by Push Data against Pacific Sunwear on US7292844B2, US7058395B2, US6983139B2, and US7212811B2. Had Push Data dismissed without prejudice, it could have refiled — the public record here leaves no ambiguity: the with-prejudice language is explicit in the notice.
Claims permanently barredPacific Sunwear exits with full protection — at no disclosed cost
Pacific Sunwear never filed an answer, incurred no formal litigation cost under the court’s fee-allocation order, and now holds a permanent shield against re-assertion of these four patents by Push Data. The cost-bearing provision — each party bears its own fees — suggests no fee-shifting motion was pursued. Whether Pacific Sunwear paid any settlement consideration remains undisclosed on the public docket.
Defendant fully protectedQuick resolution limits precedent but signals plaintiff risk calculus
No claim construction, validity ruling, or infringement finding was issued, so the patents’ enforceability against other defendants is unchanged. However, the with-prejudice dismissal at the pre-answer stage — against a retail mobile app target — may suggest Push Data reassessed litigation economics or faced procedural challenges specific to this defendant. Other mobile app operators accused under these patents cannot rely on this dismissal as a merits defense.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) explicitly and adds the with-prejudice designation — language that transforms what is procedurally a voluntary exit into a permanent bar on re-litigation. The cost-neutrality provision (‘each party shall bear its own costs’) is standard in negotiated pre-answer exits and forecloses any fee-shifting claim under 35 U.S.C. § 285. No merits analysis, claim construction, or validity ruling accompanies this termination, leaving the patents’ legal status intact for enforcement against third parties.
US7292844B2, US7058395B2, US6983139B2 & US7212811B2 — Mobile Data Delivery Patents
The four asserted patents — US7292844B2, US7058395B2, US6983139B2, and US7212811B2 — share a common technical lineage in mobile data delivery, push notification infrastructure, and wireless communication architectures. Filed across application numbers in the mid-2000s, these patents predate the modern app store era, which is typical of mobile data NPE portfolios that assert foundational wireless delivery claims against contemporary mobile commerce implementations.
Push Data’s assertion against the PacSun app and rewards platform suggests claim mapping to mobile app data synchronisation, loyalty program communication delivery, and push notification dispatch — features now ubiquitous across retail mobile applications. The portfolio’s breadth across four patents targeting both iOS/Android apps and a web-based rewards portal indicates a multi-vector assertion strategy. For mobile commerce operators, this portfolio represents a non-trivial enforcement risk until claim-level invalidity or non-infringement positions are established.
Should you run an FTO against US7292844B2 and the Push Data portfolio?
Any retailer or mobile commerce platform operating push notification features, in-app messaging, or loyalty reward data delivery should treat this four-patent portfolio as an active FTO concern. Push Data’s targeting of PacSun’s iOS app, Android app, and rewards platform simultaneously suggests claim scope broad enough to cover standard mobile engagement architectures — not bespoke implementations. The with-prejudice dismissal against PacSun provides no invalidity shield for other operators.

What this case signals for the mobile app patent licensing landscape
A four-patent assertion resolved in 110 days with no merits ruling carries specific signals for mobile commerce IP strategy.
Pre-answer dismissals with prejudice are rare — and deliberate
Most plaintiffs who exit pre-answer choose without-prejudice dismissal to preserve optionality. Push Data’s with-prejudice election here is atypical and suggests either a negotiated exit with consideration, or a definitive strategic decision to abandon this enforcement target. Mobile app operators receiving demand letters from similar NPEs should note this outcome as a potential negotiating benchmark.
These four patents remain live against other defendants
The dismissal only bars Push Data’s claims against Pacific Sunwear. US7292844B2, US7058395B2, US6983139B2, and US7212811B2 retain their issued status and can be asserted against other mobile application operators. Retailers and app developers operating push notification or mobile data delivery features should treat this case as a monitoring signal, not a clearance event.
Push v Pacific — key questions answered
Push Data dismissed its four-patent infringement action against Pacific Sunwear with prejudice under Rule 41(a)(1)(A)(i). This means the dismissal operates as a final judgment on the merits for res judicata purposes — Push Data cannot refile the same infringement claims against Pacific Sunwear on these four patents. The dismissal does not affect Push Data’s ability to assert these patents against other defendants.
Push Data asserted four U.S. patents: US7292844B2, US7058395B2, US6983139B2, and US7212811B2. All relate to mobile data delivery and wireless communication architectures. The complaint targeted the PacSun iOS mobile app, Android mobile app, and the PacSun Rewards loyalty platform.
The public record does not disclose the reason. Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss without court order at any time before the defendant serves an answer. Common reasons for pre-answer dismissal include a negotiated settlement reached off-docket, a strategic reassessment of litigation economics, or identification of a procedural or substantive issue with the complaint. The with-prejudice election is atypical for a purely strategic exit and may suggest some form of consideration was exchanged.
No. Because the case was dismissed without any merits ruling, claim construction, or validity analysis, it creates no legal precedent that other defendants can invoke. The patents US7292844B2, US7058395B2, US6983139B2, and US7212811B2 remain issued and enforceable against third parties. Other mobile app operators cannot rely on this dismissal as a shield against Push Data’s enforcement activity.
The dismissal notice expressly states that each party shall bear its own costs, expenses, and attorneys’ fees. No fee-shifting award was made under 35 U.S.C. § 285 or Rule 54. This cost-neutral outcome is consistent with a pre-answer resolution where neither party incurred substantial litigation expense and no exceptional case finding was sought.
