Payvox v. CMS Industries: Patent Infringement Suit Dismissed With Prejudice
Payvox LLC asserted US10762555B2 — a patent covering automated mass media commerce systems — against CMS Industries Ltd. in the Eastern District of Texas. The case resolved in 162 days when Payvox voluntarily dismissed its own claims with prejudice, permanently extinguishing its right to re-file.
Payvox’s Mass Media Commerce Patent Ends in a Binding Self-Dismissal
On April 16, 2025, Payvox LLC filed a patent infringement action against CMS Industries Ltd. in the United States District Court for the Eastern District of Texas (Case No. 2:25-cv-00395). The asserted patent, US10762555B2, covers systems and methods for automated mass media commerce — a technology area increasingly relevant to digital advertising, e-commerce integration, and automated transactional platforms. Payvox was represented by Rabicoff Law LLC, a firm known for asserting patents in the Eastern District of Texas.
The case closed on September 25, 2025 — 162 days after filing — when Payvox filed a Notice of Voluntary Dismissal with Prejudice. The Court accepted the notice pursuant to Rule 41(a)(1)(A)(i) and formally dismissed all pending claims and causes of action with prejudice. Critically, each party was ordered to bear its own costs, expenses, and attorneys’ fees, suggesting no financial settlement was ordered by the court, though private arrangements cannot be ruled out from the public record.
The 162-day timeline is notably brief for a patent infringement case in the Eastern District of Texas, which typically sees cases run considerably longer before resolution. A dismissal with prejudice filed voluntarily by the plaintiff — particularly without a fee award — is consistent with either a private settlement, a licensing agreement reached out of court, or a strategic reassessment of claim strength. The public record does not disclose which of these factors drove the resolution, and the terms of any potential agreement remain confidential.

Dismissed with prejudice: what the voluntary exit means for both parties
Rule 41 dismissal with prejudice operates as a final judgment
A voluntary dismissal with prejudice under Rule 41(a)(1)(A)(i) is the plaintiff’s own act, but it carries the same preclusive force as a final judgment on the merits. Payvox cannot re-file this specific action against CMS Industries on the same patent claims. The court’s acceptance and formal order closes the case permanently, with no avenue to revive these particular claims in any federal court.
Claim preclusion appliesPayvox surrenders its infringement claims against CMS permanently
By dismissing with prejudice, Payvox has permanently relinquished its right to pursue CMS Industries on these claims under US10762555B2. This is the most consequential form of voluntary exit available to a plaintiff. The public record does not reveal whether Payvox received consideration — such as a licensing fee or cross-licence — in exchange for this dismissal. A private settlement or licence agreement reached before dismissal would not appear in the court record.
No re-filing against CMSCMS Industries exits litigation without a public merit ruling
CMS Industries Ltd. achieves a clean exit: the case is closed with prejudice, meaning no court ever ruled that its products infringe US10762555B2. However, the patent itself remains valid and enforceable — Payvox could still assert it against other defendants. CMS bears its own legal costs, consistent with the mutual cost-bearing order, suggesting no formal fee-shifting victory under 35 U.S.C. § 285.
No infringement findingUS10762555B2 remains live — other market players face ongoing exposure
The dismissal resolves only the dispute with CMS Industries. US10762555B2 covering automated mass media commerce systems is unaffected in scope or validity by this outcome. Other companies operating in digital commerce, programmatic media, or automated transactional platforms should treat this patent as an active enforcement risk. The swift resolution and lack of fee-shifting suggest Payvox’s assertion strategy may continue against other targets in this technology space.

Official order — verbatim text
The court’s order accepts Payvox’s Rule 41(a)(1)(A)(i) notice and formally enters dismissal with prejudice across all pending claims. The phrasing ‘DISMISSED WITH PREJUDICE’ confirms this is not a temporary or procedural exit — it is a final, claim-preclusive disposition. The denial of all other pending relief as moot indicates no substantive motions had been decided on the merits before exit. The own-costs order is consistent with Rule 41 defaults absent any fee-shifting motion or exceptional case finding under 35 U.S.C. § 285.
US10762555B2 — Automated Mass Media Commerce Systems
US10762555B2, filed under application number US15/725932, protects systems and methods for automated mass media commerce — a technology that sits at the intersection of digital media delivery and automated transactional processing. The patent’s designation as a granted US utility patent (B2 suffix indicates a second publication, post-grant) signals a substantive examination process. The application number prefix US15/ places the filing in the post-2012 AIA regime, meaning it is subject to inter partes review challenges at the USPTO Patent Trial and Appeal Board.
The strategic relevance of US10762555B2 extends across any platform that automates purchase, subscription, or transactional steps within a mass media context — including streaming services with integrated commerce, programmatic advertising with direct purchase, and digital broadcast platforms with automated fulfilment. Patent assertion entities holding this type of broad-claim media commerce IP typically target companies at scale. The fact that this patent was asserted in the Eastern District of Texas — consistently the most plaintiff-favoured district in the US — signals enforcement intent beyond this single defendant.
Should your product be cleared against US10762555B2?
Any company operating a platform that automates transactional or purchasing actions in connection with mass media content should assess freedom-to-operate against US10762555B2. This includes digital advertising platforms with integrated checkout, streaming services with in-content commerce, automated media buying systems, and programmatic transactional engines. The patent’s broad title language — ‘automated mass media commerce’ — and the plaintiff’s demonstrated willingness to assert it in the Eastern District of Texas make pre-emptive FTO analysis commercially prudent.

What this case signals for the automated commerce IP landscape
A fast dismissal with prejudice in the Eastern District of Texas rarely tells the full story — and this case is no exception.
Eastern District filings by NPEs warrant early FTO review
Payvox filed in the Eastern District of Texas — a plaintiff-friendly venue consistently favoured by non-practising entities. Companies in the automated commerce, programmatic media, or digital transaction space should conduct FTO analysis against US10762555B2 proactively, before receiving a demand letter. The filing-to-dismissal speed here suggests the assertion playbook is active.
Own-costs orders signal no judicial fee-shifting — but risk persists
The mutual own-costs order means neither party secured a § 285 exceptional case finding. For defendants in similar positions, this underscores that even a favourable exit from NPE litigation typically does not result in cost recovery. Budget for litigation defence costs as a baseline risk when operating in patent-dense technology sectors like automated media commerce.
Payvox v CMS — key questions answered
The dismissal with prejudice means Payvox cannot re-file this specific infringement action against CMS Industries Ltd. under US10762555B2. However, US10762555B2 remains a valid and enforceable patent that Payvox may assert against other defendants. The ruling carries no precedential finding on patent validity or infringement.
The public record does not disclose Payvox’s reasons. A voluntary dismissal with prejudice at this stage is consistent with a confidential settlement or licence agreement, a strategic reassessment of claim strength, or a commercial resolution reached outside the court process. The mutual own-costs order suggests no judicial fee-shifting was involved.
US10762555B2 is a granted US utility patent (application US15/725932) covering systems and methods for automated mass media commerce. It sits at the intersection of digital media delivery and automated transactional processing, potentially encompassing streaming commerce, programmatic purchasing, and automated media transaction platforms.
No. A voluntary dismissal with prejudice is a procedural termination of the specific lawsuit — it does not constitute a ruling on patent validity or infringement. US10762555B2 remains fully valid and enforceable. Third parties cannot rely on this case outcome as evidence of invalidity or non-infringement.
The court’s order that each party bear its own costs, expenses, and attorneys’ fees means CMS Industries cannot recover its legal defence costs from Payvox. This is consistent with Rule 41 defaults and the absence of a § 285 exceptional case motion. It highlights a common challenge for defendants in NPE litigation — even a favourable exit typically does not result in cost recovery.
