Random Chat v. Kay Jewelers: TCP/IP Patent Dismissed With Prejudice
Random Chat, LLC asserted US8402099B2 — a method patent for TCP/IP and UDP-based multimedia communications — against jewellery retailer Kay Jewelers in the Western District of Texas. The case ended by joint stipulation of dismissal with prejudice after 259 days, with each party bearing its own attorneys’ fees and costs.
TCP/IP Communication Patent Meets Stipulated End in W.D. Texas
Random Chat, LLC filed suit against Kay Jewelers, Inc. on 28 February 2025 in the Western District of Texas (Case No. 7:25-cv-00096), asserting infringement of US8402099B2. The patent covers a method for carrying out multimedia communication based on network protocols — specifically TCP/IP and/or UDP — technology broadly applicable to internet-connected consumer-facing platforms. Counsel of record for plaintiff was William P. Ramey III of Ramey LLP, a firm frequently associated with NPE patent enforcement campaigns; Kay Jewelers was defended by Fish & Richardson LLP.
The case closed on 14 November 2025, 259 days after filing, via a joint stipulation of dismissal with prejudice filed under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Under Fifth Circuit precedent cited by the court — Yesh Music v. Lakewood Church, 727 F.3d 356 (5th Cir. 2013) — such stipulations are self-executing and require no judicial approval, though the court formally ordered the clerk to close the action. Dismissal with prejudice permanently bars Random Chat from re-filing the same patent claims against Kay Jewelers.
The 259-day duration and absence of a merits ruling is consistent with a negotiated resolution, though the public record does not disclose whether any financial consideration changed hands. The mutual fee-bearing arrangement — each side pays its own costs — is standard in stipulated dismissals and neither confirms nor refutes a settlement. What remains unknown is whether Kay Jewelers sought or received a covenant not to sue extending to related patents or affiliates, a provision frequently negotiated in NPE disputes of this kind.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii) stipulated dismissal — self-executing under Fifth Circuit law
Under FRCP 41(a)(1)(A)(ii), when all appearing parties sign a stipulation of dismissal it takes effect automatically upon filing — no court order is required. The Fifth Circuit confirmed in Yesh Music v. Lakewood Church that courts need not approve such stipulations. The Western District judge here followed that precedent, formally ordering closure as a ministerial act rather than a substantive ruling. No merits adjudication was made.
No merits rulingWith prejudice: Random Chat permanently barred from re-suing Kay Jewelers on this patent
Dismissal with prejudice operates as a final adjudication on the merits under res judicata principles. Random Chat, LLC cannot refile claims under US8402099B2 against Kay Jewelers in any federal court. This is a materially stronger outcome for Kay Jewelers than a without-prejudice dismissal, which would have left the door open to re-litigation. Whether the parties also agreed to broader covenant-not-to-sue terms is not disclosed in the public record.
Permanent bar on re-filingRandom Chat surrenders its right to pursue Kay Jewelers — patent survives against others
Random Chat retains ownership of US8402099B2 and may continue to assert it against third parties not party to this stipulation. The with-prejudice dismissal affects only this defendant. However, agreeing to mutual fee-bearing and a with-prejudice outcome — rather than merely walking away without prejudice — suggests Kay Jewelers’ litigation posture, backed by Fish & Richardson, may have shifted the negotiating dynamic. The strength of the patent’s remaining enforceability against other targets is unchanged by this order.
Patent remains live vs. othersNPE TCP/IP assertion strategy: reading the tea leaves of a quick stipulated end
Cases filed by Ramey LLP asserting broad communication-protocol patents against retailers typically resolve before Markman. The 259-day timeline and with-prejudice outcome is consistent with a licensing payment in exchange for dismissal — though this is speculative from public filings alone. Retailers operating TCP/IP-based customer interaction tools, live chat, or multimedia e-commerce features should note that US8402099B2 remains active and may be asserted against similarly situated defendants.

Official order — verbatim text
The stipulation language — ‘all claims for relief asserted against Defendant are dismissed with prejudice as to the asserted patent’ — is precise in scope: it extinguishes only Random Chat’s claims against Kay Jewelers under US8402099B2, and does not purport to invalidate the patent or bind third parties. The mutual fee-bearing clause reinforces that no party was adjudged the prevailing party, which is consistent with a negotiated exit rather than a substantive defeat for either side. The court’s invocation of Yesh Music confirms the purely ministerial nature of the closure order.
US8402099B2 — TCP/IP and UDP Multimedia Communication Method
US8402099B2, filed under application number US12/675046, protects a method for carrying out multimedia communication based on internet network protocols — specifically TCP/IP and/or UDP. The patent’s claims are directed to the protocol-level handling of multimedia data streams across networked environments. Its application date places it in the era of early web-based real-time communication, predating the widespread adoption of WebRTC and cloud-based contact-centre platforms. The patent has been granted B2 status, indicating it survived re-examination or post-grant proceedings.
The strategic reach of US8402099B2 is broad: TCP/IP and UDP underpin virtually all internet communication, meaning any product or service delivering multimedia content — video, voice, or rich-media — over a standard network connection could fall within scope depending on claim construction. For e-commerce operators, customer service chat platforms, and digital communication tool vendors, this patent represents a non-trivial assertion risk. Its deployment against a major jewellery retailer rather than a technology company suggests the NPE strategy targets the end-user implementation layer, not infrastructure providers.
Should you run an FTO against US8402099B2?
Any company deploying TCP/IP or UDP-based multimedia communication features — live video chat, voice-over-IP customer service, real-time multimedia streaming, or interactive web-based communication tools — should assess its exposure to US8402099B2. The patent’s assertion against a retail e-commerce operator confirms that the holder is willing to pursue non-technology defendants whose platforms incidentally incorporate covered methods. Product and engineering teams building or licensing such features should not assume the patent is dormant following this dismissal.
PatSnap Eureka’s FTO Search Agent can map the claim landscape of US8402099B2 against your specific product implementation, identify prior art that may support an invalidity argument, and surface continuation applications within the US12/675046 family that could present additional exposure. Eureka’s litigation monitoring also tracks new filings by Ramey LLP in W.D. Texas so your team receives early warning of any new assertion campaign targeting your sector.

What this case signals for the TCP/IP and e-commerce patent IP landscape
A rapid stipulated end against a major retailer suggests either a licence deal or a strong invalidity position — both carry strategy implications.
Retailers using live chat or TCP/IP multimedia features face ongoing NPE risk
US8402099B2 targets method claims for TCP/IP and UDP multimedia communications — technology embedded in virtually every modern e-commerce platform. Kay Jewelers’ with-prejudice dismissal does not neutralise the patent for the broader retail sector. Any retailer operating web-based customer communication tools should assess whether their implementation falls within the claim scope of this patent.
Fish & Richardson’s involvement signals Kay Jewelers mounted a credible defence
Retaining Fish & Richardson — one of the leading patent litigation defence firms — against a Ramey LLP assertion typically signals a defendant prepared to litigate to Markman or beyond. The with-prejudice outcome may reflect leverage gained through IPR preparation, prior art searches, or claim construction arguments that made continued assertion commercially unattractive for Random Chat.
Random v Kay — key questions answered
Dismissal with prejudice in this case means Random Chat, LLC is permanently barred from re-filing patent infringement claims under US8402099B2 against Kay Jewelers, Inc. in any federal court. It operates as a final adjudication on the merits under res judicata doctrine. The dismissal was entered by joint stipulation under FRCP 41(a)(1)(A)(ii) and does not affect Random Chat’s ability to assert the same patent against other defendants.
The public record does not confirm a financial settlement. The case closed via a joint stipulation of dismissal with prejudice, with each party bearing its own fees and costs. This structure is consistent with a confidential licence or settlement agreement, but no such terms appear in the court docket. The 259-day duration and with-prejudice outcome suggest a negotiated resolution rather than a unilateral withdrawal by plaintiff.
US8402099B2 claims a method for carrying out multimedia communication using TCP/IP and/or UDP network protocols — the foundational protocols of internet communication. Its assertion against Kay Jewelers, a retail chain, suggests the NPE holder targeted the retailer’s customer-facing digital communication tools such as live chat, video consultation, or multimedia e-commerce features rather than underlying infrastructure, which is a common strategy for protocol-level patent assertion entities.
No. A dismissal by joint stipulation under FRCP 41(a)(1)(A)(ii) carries no merits adjudication. The court made no ruling on infringement, validity, or claim construction. US8402099B2 remains a granted, enforceable patent and Random Chat may continue to assert it against any third party not covered by the stipulation. Companies in similar technology or retail sectors should not treat this dismissal as a signal that the patent is invalid or unenforceable.
