Random Chat, LLC v. Camelot SI, LLC — Voluntarily Dismissed Without Prejudice
Random Chat, LLC asserted US8402099B2 — covering network protocol-based multimedia communication over TCP/IP and UDP — against Camelot SI, LLC in the Eastern District of Michigan. The plaintiff filed a voluntary dismissal without prejudice under Rule 41(a)(1)(A)(i) after just 123 days, leaving the door open for future enforcement.
A fast exit: TCP/IP multimedia patent suit dropped before any ruling
Random Chat, LLC filed suit against Camelot SI, LLC on May 30, 2025 in the Eastern District of Michigan, asserting US8402099B2, a patent covering methods for carrying out multimedia communications over network protocols, specifically TCP/IP and UDP. The case was filed by Ramey LLP, a firm with a substantial patent assertion practice, against Camelot SI, represented by Jones Day’s Detroit office. No substantive motions or claim construction proceedings appear to have been reached before the case closed.
On September 30, 2025 — just 123 days after filing — Random Chat filed a Notice of Voluntary Dismissal Without Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court ordered the case dismissed accordingly. A dismissal without prejudice means the plaintiff has not relinquished its underlying claims; Random Chat retains the legal right to reassert the same patent against Camelot SI or other defendants in a future action.
The speed of the dismissal — before any substantive court order — is consistent with early-stage negotiation dynamics, licensing discussions, or a strategic reassessment of venue or claim scope. The public record does not disclose whether any settlement or licensing agreement was reached. What is clear is that no judicial finding was made on infringement, validity, or claim construction, leaving the patent’s enforceability fully intact as a matter of public record.

Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral right to exit
Federal Rule of Civil Procedure 41(a)(1)(A)(i) permits a plaintiff to dismiss a case without a court order — and without prejudice — before the defendant has served an answer or motion for summary judgment. This is the earliest and cleanest exit available. Because the dismissal is without prejudice, it carries no preclusive effect on future litigation involving the same patent and defendant.
No merits adjudicationWithout prejudice: the distinction matters significantly
A dismissal without prejudice differs materially from one with prejudice. With prejudice signals finality — claims are extinguished. Without prejudice leaves claims alive. Random Chat filed explicitly without prejudice, meaning it could refile against Camelot SI or assert US8402099B2 against other parties. Whether a settlement agreement exists that effectively resolves the dispute is not reflected in the public court record.
Refiling remains possibleCamelot SI avoids a ruling — but risk is not fully extinguished
Camelot SI, represented by Jones Day Detroit, secured no declaratory judgment of non-infringement or invalidity. While the immediate litigation threat is removed, the without-prejudice nature of the dismissal means Camelot SI cannot treat this as a final resolution. If no licensing agreement was reached, the company should monitor Random Chat’s future enforcement activity around US8402099B2.
No declaratory judgment obtainedTCP/IP communication patents: enforcement risk persists post-dismissal
US8402099B2 remains fully in force with no adverse judicial finding on validity or infringement. Companies operating real-time multimedia communication platforms over TCP/IP or UDP protocols should treat this case as a signal that the patent is being actively monitored for licensing opportunities. Ramey LLP’s involvement suggests a structured assertion programme rather than a one-off filing.

Official order — verbatim text
The dismissal order is brief and purely procedural: the court confirms Random Chat’s Rule 41(a)(1)(A)(i) notice and orders the case closed. No findings on infringement, validity, claim construction, or damages were made. The without-prejudice qualifier is legally significant — it preserves Random Chat’s full right to refile. For Camelot SI, this is a pause, not a resolution. The absence of any fee-shifting or costs award under 35 U.S.C. § 285 suggests the case did not reach a stage where exceptional-case arguments could be advanced.
US8402099B2 — TCP/IP and UDP multimedia communication method
US8402099B2, filed under application number US12/675046, protects a method for carrying out multimedia communications based on network protocols — specifically TCP/IP and UDP. The patent sits at the intersection of real-time communication and internet protocol architecture, a domain that underpins VoIP services, video conferencing platforms, and streaming media delivery. The application date context places its priority in an era predating widespread WebRTC and cloud-native communication infrastructure, which may give its claims reach over modern implementations.
For the communications technology sector, US8402099B2 represents a potentially broad assertion vehicle. Method-based network protocol patents are notoriously difficult to design around because the infringement analysis tracks software behaviour rather than hardware components. Any platform transmitting multimedia content over TCP/IP or UDP — including collaboration tools, customer contact software, and streaming applications — should assess claim-by-claim exposure. The involvement of Ramey LLP as plaintiff’s counsel is consistent with a coordinated, multi-defendant licensing programme rather than a targeted single-defendant dispute.
Should your product team run an FTO against US8402099B2?
If your product transmits audio, video, or combined multimedia data over TCP/IP or UDP — whether in a SaaS communication platform, an embedded VoIP module, or a real-time collaboration tool — US8402099B2 is a patent your IP team should have mapped. The without-prejudice dismissal in this case means enforcement activity has not concluded. R&D and product teams launching or updating multimedia communication features face non-trivial risk of being targeted in a subsequent filing, particularly given the assertion firm’s track record.
PatSnap Eureka’s FTO Search Agent allows you to run a structured freedom-to-operate analysis against US8402099B2 and its application family (US12/675046), surfacing claim charts, prosecution history insights, and prior art landscapes in a fraction of the time required for manual review. Eureka also monitors continuation applications and related family members, alerting your team if new claims issue that could change your risk profile — a critical capability when facing a serial asserter.

What this case signals for the network communications IP landscape
A fast voluntary dismissal without prejudice from a serial assertion firm rarely signals defeat — it often signals strategy.
Ramey LLP filings warrant systematic monitoring across TCP/IP portfolios
Ramey LLP is a prolific patent assertion firm. A voluntary dismissal at the 123-day mark — before any answer was filed — is consistent with early licensing discussions or a pivot to different defendants. Companies with multimedia communication products operating over TCP/IP or UDP should audit their exposure to US8402099B2 and related continuation patents now, not after a second filing.
Without-prejudice exits leave defendants in a legally ambiguous position
Camelot SI obtained no declaratory relief. If no confidential settlement was reached, it remains exposed to refiling. In-house counsel at similarly positioned companies should track the prosecution history of US8402099B2 and any continuation applications that may broaden or shift claim scope before a future assertion.
Random v Camelot — key questions answered
Random Chat filed a Rule 41(a)(1)(A)(i) notice, allowing unilateral dismissal before Camelot SI filed an answer. The without-prejudice designation means Random Chat’s claims are not extinguished — it can refile the same patent infringement action in the future. No merits ruling was made by the court.
US8402099B2 covers methods for conducting multimedia communications over TCP/IP and UDP network protocols. This encompasses a wide range of modern communication technologies including VoIP, video conferencing, and real-time data streaming. Its method-based claims can apply broadly to software implementations, making it relevant to any company offering or embedding multimedia communication features.
Yes. A without-prejudice dismissal under Rule 41(a)(1)(A)(i) carries no preclusive effect. Random Chat retains the right to assert US8402099B2 against Camelot SI or any other defendant in a future action, subject to any applicable statute of limitations for patent infringement (generally six years under 35 U.S.C. § 286).
Ramey LLP, led by William P. Ramey III, is a Houston-based firm with an extensive patent assertion practice spanning numerous technology domains. Their involvement as plaintiff’s counsel is typically associated with organised, multi-defendant licensing campaigns rather than isolated disputes, suggesting US8402099B2 may be asserted against additional defendants in parallel or subsequent filings.
No. The case was dismissed at the earliest possible stage — before any answer, claim construction, or substantive motion. The court’s order merely confirmed the voluntary dismissal under Rule 41. US8402099B2 therefore retains its full presumption of validity under 35 U.S.C. § 282, and no infringement finding — for or against either party — appears in the public record.
