Droplets, Inc. v. Walmart, Inc. — Dismissed With Prejudice After 391 Days
Droplets, Inc. asserted US6687745B1 — a patent covering interactive web application delivery — against Walmart’s iOS and Android mobile apps and walmart.com. Filed in the Eastern District of Texas before Judge Rodney Gilstrap, the case closed after 391 days via joint stipulation of dismissal with prejudice, with each party bearing its own costs.
Mobile App Patent Suit Against Walmart Ends With Prejudice in E.D. Texas
Droplets, Inc. filed this patent infringement action on November 22, 2024, in the Eastern District of Texas (Case No. 2:24-cv-00970) before Judge Rodney Gilstrap — one of the most experienced patent trial judges in the United States. Droplets asserted US6687745B1 against Walmart’s mobile applications (iOS and Android) and its website walmart.com, alleging that Walmart’s consumer-facing digital platforms infringed its patent covering interactive web application delivery technology.
The case resolved on December 18, 2025, when the parties filed a Joint Stipulation of Dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The court accepted and acknowledged the dismissal with prejudice, meaning Droplets is permanently barred from re-asserting the same claims against Walmart. No damages were awarded and no fee-shifting order was entered — each party is responsible for its own costs, expenses, and attorneys’ fees. The stipulation also triggered closure of the Lead Case No. 2:24-cv-970 as no consolidated parties or claims remained.
The 391-day duration — spanning from filing through to the joint stipulation — suggests the parties engaged in substantive litigation activity, potentially including early claim construction exchanges or licensing discussions, before reaching agreement. The ‘with prejudice’ designation and mutual cost-bearing arrangement is consistent with a confidential settlement, though the public record does not confirm any financial terms. What remains unknown is whether a licensing agreement was reached and on what terms — a detail that would materially affect how competitors interpret this resolution.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii) dismissal with prejudice: the door closes permanently
A dismissal with prejudice under Fed. R. Civ. P. 41(a)(1)(A)(ii) is a joint stipulation by both parties that functions as a final adjudication on the merits. Unlike a without-prejudice dismissal, Droplets cannot refile these specific infringement claims against Walmart based on US6687745B1. The court’s acceptance formalises the agreement and directs closure of both the member and lead consolidated cases.
Permanent bar on re-filingNo public terms — settlement likely but not confirmed
The with-prejudice designation and mutual cost-bearing arrangement is a hallmark pattern of a confidential settlement, but the public record contains no financial terms, licensing agreement, or damages figure. It is equally possible that Droplets concluded litigation was not commercially viable following claim construction or invalidity exchanges. Competitors and licensees should not assume a payment was made — the record is silent on this point.
Settlement terms undisclosedDroplets permanently relinquishes its claims against Walmart
By agreeing to dismissal with prejudice, Droplets, Inc. has permanently extinguished its infringement claims against Walmart under US6687745B1. If a settlement payment was agreed privately, this may represent a commercial success. However, Droplets retains the patent and may continue to assert it against other defendants — the preclusive effect applies only to Walmart for these specific claims.
Claims against Walmart extinguishedWalmart secures finality — no ongoing exposure on this assertion
Walmart’s dismissal with prejudice provides strong finality: Droplets cannot re-assert US6687745B1 against Walmart’s mobile apps or website on the facts litigated here. The each-party-bears-own-costs arrangement avoids any suggestion of exceptional case treatment. Walmart’s retail technology stack — including its iOS/Android apps and walmart.com — is no longer exposed to this specific patent assertion from Droplets.

Official order — verbatim text
The court’s order accepts a joint Rule 41(a)(1)(A)(ii) stipulation that closes both the member case (2:24-cv-969) and the lead consolidated case (2:24-cv-970). The ‘dismissed with prejudice’ language is legally significant: it bars Droplets from re-litigating these infringement claims against Walmart, and courts treat such stipulations as final judgments on the merits. The mutual cost-bearing arrangement forecloses any exceptional case argument under 35 U.S.C. § 285. No claim construction order or merits ruling was entered, leaving the patent’s validity and scope publicly unadjudicated.
US6687745B1 — Interactive Web Application Delivery Technology
US6687745B1 (Application No. US09/599382) is a granted U.S. utility patent covering technology relating to the interactive delivery of applications over the web to client devices. The patent addresses how software applications — particularly those requiring dynamic, stateful interaction — are communicated to and executed on user devices. In the context of this case, Droplets alleged this covers the delivery mechanisms underlying Walmart’s iOS and Android mobile applications and its walmart.com website infrastructure.
The strategic significance of this patent lies in its potential breadth: if claim scope extends to standard mechanisms for delivering interactive web and mobile experiences, it could implicate a wide range of consumer-facing digital platforms across retail, fintech, travel, and media. The fact that Droplets targeted one of the world’s largest retailers — and pursued the case for 391 days before a joint dismissal — suggests Droplets views the patent as commercially viable. Competitors operating similar mobile app stacks should monitor Droplets’ litigation activity closely for follow-on assertions.
Should you run an FTO against US6687745B1?
Any organisation operating a consumer-facing mobile application (iOS or Android) or an interactive website that delivers dynamic, stateful experiences to users should assess its exposure to US6687745B1. This is particularly urgent for retail, e-commerce, travel, and financial services companies whose digital products rely on similar application delivery architectures to those identified in this complaint. The patent remains in force and the dismissal binds only Walmart — Droplets can file against new defendants tomorrow.
PatSnap Eureka’s FTO Search Agent allows product and IP teams to map claim language from US6687745B1 against their specific technology stack, identify prior art that could support an IPR petition, and benchmark against related assertions Droplets has filed across other jurisdictions. Running a structured FTO now — before receiving a demand letter — is materially cheaper than responding to E.D. Texas litigation. Eureka surfaces claim charts, prosecution history, and citation landscapes in a single workflow.

What this case signals for the mobile app and e-commerce IP landscape
Droplets’ assertion of a web application delivery patent against a top-five U.S. retailer’s digital stack highlights enduring PAE risk for consumer mobile platforms.
Interactive web delivery patents remain live enforcement tools against retail apps
US6687745B1 covers technology at the core of how mobile apps and websites deliver interactive experiences. The fact that Droplets targeted both Walmart’s iOS/Android apps and walmart.com suggests broad claim scope claims. E-commerce and retail technology teams should treat web application delivery patents as live litigation risk — not legacy IP.
E.D. Texas and Judge Gilstrap remain the default venue for PAE assertions
Filing before Judge Gilstrap in the Eastern District of Texas is a deliberate strategic choice by patent assertion entities. His court’s docket management and claim construction processes create predictable — and often plaintiff-favourable — early case dynamics. Defendants in this venue face real pressure to resolve before Markman hearings crystallise adverse constructions.
Droplets v Walmart — key questions answered
The case was dismissed with prejudice on December 18, 2025, pursuant to a Joint Stipulation under Fed. R. Civ. P. 41(a)(1)(A)(ii). Each party bears its own costs. Droplets cannot re-assert the same claims against Walmart based on US6687745B1. No merits ruling or claim construction order was publicly entered.
Droplets asserted US6687745B1 (App. No. US09/599382) against Walmart’s iOS and Android mobile applications and the walmart.com website. The patent relates to interactive web application delivery technology. Both the mobile apps and the website’s interactive delivery infrastructure were identified as accused products in the complaint.
Dismissed with prejudice means Droplets, Inc. is permanently barred from re-filing the same patent infringement claims against Walmart under US6687745B1. It functions as a final adjudication on the merits, even though no court ruling on validity or infringement was entered. The stipulated dismissal was accepted by Judge Rodney Gilstrap.
The public record does not confirm a settlement payment or licensing agreement. The with-prejudice dismissal and mutual cost-bearing arrangement is consistent with a confidential settlement, but this cannot be confirmed from available court filings. No damages figure or licensing fee appears in the public docket for Case No. 2:24-cv-00970.
Yes. The dismissal with prejudice binds only Walmart — Droplets retains US6687745B1 and may assert it against other defendants. Companies operating consumer-facing mobile apps or interactive websites with similar delivery architectures should assess their FTO position. Droplets simultaneously filed related actions, including against Home Depot, suggesting an active multi-defendant assertion campaign.
