Random Chat, LLC v. PayPal: Voluntary Dismissal With Prejudice After 165 Days
Random Chat, LLC asserted US8402099B2 — covering TCP/IP and UDP-based multimedia communication methods — against PayPal in the Western District of Texas. The case ended in a voluntary dismissal with prejudice by the plaintiff under Rule 41(a)(1)(A)(i), before PayPal filed any answer or dispositive motion, with each party bearing its own costs.
A pre-answer exit: Random Chat drops PayPal suit with prejudice
Random Chat, LLC filed suit against PayPal, Inc. on February 28, 2025 in the Western District of Texas, asserting infringement of US8402099B2. The patent, filed under application number US12/675046, claims methods for carrying out multimedia communications over network protocols, specifically TCP/IP and UDP — technologies foundational to modern internet-based messaging and payment platforms.
The case terminated on August 12, 2025, when the plaintiff filed a Notice of Voluntary Dismissal With Prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because PayPal had not yet served an answer or a motion for summary judgment, the dismissal was self-effectuating and required no court order. The with-prejudice designation is legally significant: it extinguishes Random Chat’s right to refile the same claims against PayPal on the same patent.
The 165-day arc — from filing to dismissal before any substantive defence was filed — is consistent with a pattern sometimes seen in patent assertion entity litigation, where early pre-answer resolution may reflect licensing discussions, a strategic reassessment, or an inability to sustain the action. The public record does not disclose whether any settlement or licensing arrangement was reached; the mutual cost-bearing order neither confirms nor forecloses that possibility.

Dismissed with prejudice: what Rule 41 means for both parties
Rule 41(a)(1)(A)(i): a self-effectuating exit before answer
Under FRCP 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the defendant serves an answer or summary judgment motion. Because PayPal had not filed either, Random Chat’s notice was self-effectuating — the case terminated by operation of law, not by judicial order. The with-prejudice designation was the plaintiff’s own choice and carries permanent claim-preclusion consequences.
No court order requiredWith prejudice: Random Chat cannot refile these claims against PayPal
A dismissal with prejudice operates as a final adjudication on the merits for res judicata purposes. Random Chat is permanently barred from reasserting the same claims under US8402099B2 against PayPal. This is a materially stronger outcome for PayPal than a without-prejudice dismissal, which would have left the door open to refiling. The public record does not disclose whether a financial settlement accompanied the dismissal.
Claim-preclusive for PayPalRandom Chat forfeits future enforcement against PayPal on this patent
By electing a with-prejudice dismissal, Random Chat permanently surrendered its infringement claims against PayPal under US8402099B2. Whether this reflects a settlement payment, a licensing agreement, or a unilateral withdrawal is not apparent from the public docket. The patent itself remains in force and can still be asserted against other defendants — the preclusive effect is limited to PayPal.
Patent remains enforceable vs. othersPayPal is clear; other platforms using TCP/IP multimedia protocols remain at risk
PayPal has achieved permanent protection from this specific claim set. However, US8402099B2 remains an active asset. Companies operating real-time messaging, video calling, or multimedia communication features over TCP/IP or UDP protocols — particularly in fintech, communications, and social platforms — should assess their exposure. The Western District of Texas remains a favoured venue for such assertions.

Official order — verbatim text
The court’s order confirms the dismissal was effectuated by operation of Rule 41(a)(1)(A)(i) without judicial intervention — a procedural posture that reflects how early in the litigation PayPal was when Random Chat elected to exit. The with-prejudice designation, chosen by the plaintiff rather than imposed by the court, is the legally operative fact: it converts what would otherwise be a neutral withdrawal into a permanent bar on the same claims. The mutual cost-bearing provision, standard in self-effectuating Rule 41 dismissals, provides no signal as to whether financial consideration changed hands.
US8402099B2 — TCP/IP and UDP multimedia communication method
US8402099B2, filed under application number US12/675046, claims methods for conducting multimedia communications over standard internet protocols — specifically TCP/IP and UDP. These protocols are the foundational transport layer of virtually all internet-based real-time communication: VoIP, video calls, instant messaging, and data-driven communication features embedded in consumer and enterprise applications. The patent’s broad protocol framing gives it potential relevance across a wide range of modern digital products.
The strategic value of this patent lies in the ubiquity of its subject matter. TCP/IP and UDP underpin not just dedicated communications platforms but also embedded messaging and notification features in payment apps, social platforms, and enterprise SaaS tools. For a patent assertion entity, this breadth supports a multi-defendant licensing strategy. PayPal was presumably targeted because its platform integrates messaging, transaction notifications, and potentially voice/video features — all potentially within the patent’s scope.
Should your product team run an FTO against US8402099B2?
If your product includes real-time messaging, VoIP, video communication, or any multimedia data transmission feature built on TCP/IP or UDP, US8402099B2 warrants a freedom-to-operate review. This patent has already been asserted against a major fintech platform. Fintech, communications, collaboration, and social platform companies operating in the US market — particularly those without a covenant not to sue from Random Chat — carry residual exposure.

What this case signals for the TCP/IP communications patent landscape
A pre-answer dismissal with prejudice in W.D. Texas raises questions about enforcement strategy and residual risk for internet communications platforms.
Pre-answer dismissals with prejudice can signal an off-docket resolution
When a plaintiff dismisses with prejudice before the defendant even files an answer, it typically suggests the parties reached an agreement — whether a licence, a covenant not to sue, or a settlement payment. The public record is silent on terms, but the with-prejudice election goes further than a plaintiff who simply walks away, suggesting some form of mutual accommodation is plausible.
US8402099B2 remains live — other defendants face unresolved exposure
The dismissal resolves nothing for third parties. US8402099B2 covers broadly-applicable TCP/IP and UDP multimedia communication methods used across messaging apps, VoIP, video conferencing, and fintech platforms. Any company with similar product features that has not received a covenant not to sue from Random Chat should treat this patent as an active enforcement risk.
Random v Paypal — key questions answered
The dismissal with prejudice permanently bars Random Chat from refiling the same claims under US8402099B2 against PayPal. This is claim-preclusive for PayPal specifically, but the patent remains enforceable against all other third parties. Random Chat retains the right to assert US8402099B2 against other defendants.
The public docket does not confirm a settlement. The plaintiff filed a voluntary dismissal with prejudice under Rule 41(a)(1)(A)(i), which is self-effectuating and requires no court order. The with-prejudice election and mutual cost-bearing order are consistent with an off-docket resolution, but no settlement terms have been publicly disclosed.
US8402099B2, filed as application US12/675046, claims methods for carrying out multimedia communications over TCP/IP and UDP network protocols. It covers the foundational internet transport layer used in VoIP, video conferencing, real-time messaging, and data communication features embedded in consumer and enterprise applications.
Rule 41(a)(1)(A)(i) permits a plaintiff to voluntarily dismiss an action without a court order by filing a notice before the opposing party serves an answer or a motion for summary judgment. In this case, PayPal had not filed either, making the dismissal self-effectuating. The court’s order confirmed this procedural posture and noted no judicial action was required.
Yes. The dismissal resolves exposure only for PayPal. US8402099B2 remains an active patent and can be asserted against any company whose products involve multimedia communication over TCP/IP or UDP. Given Ramey LLP’s track record of multi-defendant assertion campaigns in W.D. Texas, companies in fintech, VoIP, messaging, and collaboration software should consider a freedom-to-operate review.
