Push Data LLC v. Dollar Tree: Mobile App Patent Suit Dismissed With Prejudice
Push Data, LLC filed a patent infringement action against Dollar Tree, Inc. in the Eastern District of Texas, asserting three mobile data delivery patents against the Family Dollar smart coupons app. The case closed after just 155 days when Push Data voluntarily dismissed with prejudice before Dollar Tree filed any answer — permanently ending Push Data’s right to re-assert these patents against Dollar Tree.
Pre-answer dismissal with prejudice signals swift resolution in mobile patent dispute
On 8 May 2024, Push Data, LLC filed suit against Dollar Tree, Inc. in the United States District Court for the Eastern District of Texas (Case No. 4:24-cv-00400), before Judge Amos L. Mazzant. The complaint asserted infringement of three patents — US7292844B2, US7058395B2, and US7212811B2 — in connection with Dollar Tree’s Family Dollar smart coupons mobile application. The patents collectively cover mobile data delivery, push-notification, and wireless device communication technologies.
The case closed on 10 October 2024 when Push Data filed a notice of voluntary dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i), which permits a plaintiff to dismiss unilaterally before the defendant has served an answer. Dollar Tree had not yet answered the complaint, so no court order was required. Crucially, the dismissal was filed with prejudice, meaning Push Data is permanently barred from re-asserting these three patents against Dollar Tree on the same claims. Each party was left to bear its own costs, expenses, and attorneys’ fees.
Resolving in 155 days — and before any substantive response from the defence — this case is notably brief even for a pre-answer dismissal. The absence of any answer or motion practice makes it impossible to determine from the public record whether the dismissal reflected a private settlement, a licensing arrangement, or a strategic retreat. The with-prejudice designation is the defining feature: it goes beyond the default outcome of a Rule 41(a)(1)(A)(i) notice, suggesting Push Data made a deliberate, final concession of its claims against Dollar Tree rather than preserving any future enforcement option.

Dismissed with prejudice: what a Rule 41(a)(1)(A)(i) exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral right to dismiss before answer
Federal Rule of Civil Procedure 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order by filing a notice of dismissal before the defendant serves an answer or a motion for summary judgment. Because Dollar Tree had not yet answered, Push Data could invoke this right freely. The addition of ‘with prejudice’ is not the default under Rule 41 — it is a deliberate election that converts what would otherwise be a dismissal without prejudice into a final judgment on the merits against the plaintiff.
Voluntary — no court order neededWith prejudice bars any future re-filing against Dollar Tree on these patents
A dismissal with prejudice is legally equivalent to a final adjudication on the merits. Push Data permanently surrenders the right to bring the same infringement claims — under US7292844B2, US7058395B2, or US7212811B2 — against Dollar Tree in any court. By contrast, a dismissal without prejudice would have preserved that option. The public record does not disclose what prompted Push Data to accept this permanent bar, though a confidential resolution or licensing arrangement consistent with such a concession cannot be ruled out.
Claim preclusive as to Dollar TreePush Data permanently forfeits its infringement claims against Dollar Tree
By voluntarily dismissing with prejudice and agreeing that each party bears its own fees, Push Data received no publicly confirmed monetary judgment or injunction. The with-prejudice election is a significant concession — Push Data retains the three patents and may theoretically enforce them against other parties, but Dollar Tree is now shielded from these specific claims permanently. Whether Push Data obtained any private consideration (e.g. a licence) in exchange is not reflected in the public docket.
No re-filing against Dollar TreeDollar Tree exits without paying fees and with permanent claim preclusion
Dollar Tree achieved a clean exit: no answer filed, no litigation costs imposed, no injunction risk, and a permanent bar against Push Data asserting these three mobile-data patents again. Fish & Richardson’s representation suggests Dollar Tree mounted a credible defence posture, which may have influenced Push Data’s decision to dismiss early. Other retailers or app operators facing Push Data assertions involving the same patent family should note that these claims can end abruptly at the pre-answer stage.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) precisely because Dollar Tree had not yet answered — a procedural window that gave Push Data unilateral control over the exit. The operative legal effect of the with-prejudice designation is claim preclusion: courts treat it as a final judgment on the merits, foreclosing any future suit by Push Data against Dollar Tree on these patents. The absence of any fee award or public monetary terms means the commercial substance of any concurrent negotiation, if any occurred, remains entirely outside the public record.
US7292844B2, US7058395B2 & US7212811B2 — Mobile Push-Data Delivery Patents
The three patents asserted by Push Data — US7292844B2, US7058395B2, and US7212811B2 — were filed in the mid-2000s (application numbers 11/603022, 11/262731, and 11/099486 respectively) and relate to the delivery of data to and from mobile wireless devices, including push-notification and communication protocols. This technical domain covers infrastructure foundational to modern mobile loyalty, coupon-delivery, and app-based messaging systems. The filing period places these patents squarely in the era of early smartphone and wireless data platform development.
For retailers and consumer-app operators, these patents are strategically significant because push-notification and mobile coupon delivery are now ubiquitous features of loyalty apps. Push Data’s choice to target the Family Dollar smart coupons app indicates the patents are being read broadly enough to cover commercial coupon-push implementations. Any company operating a mobile app that delivers personalised offers, coupons, or notifications to end users via a wireless data channel should treat this patent family as a potential enforcement risk and consider FTO analysis as a precautionary measure.
Should your mobile app team run an FTO against US7292844B2 and related patents?
If your organisation operates a mobile application that delivers push notifications, smart coupons, or personalised promotional content to end users over wireless data channels — particularly in retail, e-commerce, or loyalty programme contexts — the Push Data patent family warrants a freedom-to-operate review. Push Data has demonstrated willingness to assert these patents in the Eastern District of Texas, a plaintiff-friendly venue, and the pre-answer dismissal against Dollar Tree does not diminish risk for other operators. R&D and product teams developing or updating coupon-delivery or notification features should flag these patents before launch.
PatSnap Eureka’s FTO Search Agent can map the claim scope of US7292844B2, US7058395B2, and US7212811B2 against your product architecture in a fraction of the time required for manual analysis. Eureka cross-references prosecution history, claim amendments, and related family members to identify design-around opportunities and invalidity vectors — giving your IP and engineering teams actionable intelligence before Push Data or a related entity files a demand letter.

What this case signals for the mobile app patent enforcement landscape
A pre-answer with-prejudice dismissal in E.D. Tex. raises pointed questions about assertion strategy and portfolio strength.
Pre-answer dismissal with prejudice is a rare and telling outcome
Most Rule 41(a)(1)(A)(i) dismissals in E.D. Tex. are filed without prejudice to preserve re-filing optionality. Electing with-prejudice status before the defendant has even answered is unusual and suggests either a private resolution was reached or Push Data concluded that proceeding carried unacceptable risk — whether from invalidity exposure, claim construction risk, or cost pressure from Fish & Richardson’s involvement.
Retailers operating loyalty and coupon apps remain in Push Data’s enforcement crosshairs
Dollar Tree may be shielded, but the three asserted patents remain active and enforceable against other parties. Companies operating mobile coupon, push-notification, or loyalty-app platforms similar to the Family Dollar smart coupons app should assess their exposure to US7292844B2, US7058395B2, and US7212811B2 — particularly if they have not yet received a demand letter from Push Data or a related entity.
Push v Dollar — key questions answered
The with-prejudice dismissal under Rule 41(a)(1)(A)(i) operates as a final adjudication on the merits against Push Data with respect to Dollar Tree. Push Data cannot re-assert US7292844B2, US7058395B2, or US7212811B2 against Dollar Tree in any future proceeding. The patents remain in force and may be asserted against other defendants.
The public record does not disclose Push Data’s motivation. Common reasons for a pre-answer with-prejudice dismissal include a confidential settlement or licensing agreement, a conclusion that the patents were vulnerable to invalidity challenge, or a strategic reassessment following engagement of opposing counsel. Fish & Richardson’s involvement for Dollar Tree suggests a credible defence posture was established early.
Three US patents were asserted: US7292844B2 (App. No. 11/603022), US7058395B2 (App. No. 11/262731), and US7212811B2 (App. No. 11/099486). All three relate to mobile data delivery, wireless device communication, and push-notification protocols. They were targeted at Dollar Tree’s Family Dollar smart coupons mobile application.
No. Claim preclusion from this dismissal applies only to Dollar Tree, Inc. Other retailers or app operators whose products may fall within the scope of the three asserted patents remain potentially exposed. The dismissal does not create any immunity for third parties and Push Data retains the right to enforce the same patents against other defendants.
