Random Chat LLC v. Carparts.com Inc — Dismissed Without Prejudice After 318 Days
Random Chat LLC filed suit against Carparts.com Inc in the Northern District of Texas asserting US8402099B2, a patent covering multimedia video, audio, and text chat communications. The case closed after 318 days with a dismissal without prejudice, leaving the door open for future litigation.
Multimedia Chat Patent Suit Against Carparts.com Ends Without Merits Ruling
Random Chat LLC filed this patent infringement action against Carparts.com Inc on May 6, 2025, in the United States District Court for the Northern District of Texas before Judge Jane J. Boyle. The sole patent asserted was US8402099B2, which covers multimedia communication technology — specifically video, audio, and/or text chat between terminals. The accused activity relates to Carparts.com's use of such communication functionality through its website and product instruction manuals.
The recorded basis of termination is Dismissed Without Prejudice. The docket order states that pursuant to the Court's March 13, 2026 electronic order and Federal Rule of Civil Procedure 41(a)(2), and following a telephone conference with lead counsel for Plaintiff, Defendant Carparts.com Inc's counterclaims filed at Dkt. 15 were dismissed without prejudice at Carparts.com's request, with Plaintiff's lead counsel agreeing to this dismissal. The specific terms of any broader resolution between the parties are not disclosed in the available record.
The case concluded in approximately ten months without any substantive merits determination on the infringement claims asserted in US8402099B2. The involvement of five defence-side attorneys from Fish & Richardson PC and Scheef & Stone LLP alongside Carparts.com's apparent agreement to dismiss its own counterclaims suggests the litigation dynamics shifted materially in the final stages, though the precise commercial or legal driver of that shift is not disclosed in the public record.

US8402099B2 — Multimedia Video, Audio & Text Chat Communications
Any e-commerce operator, SaaS platform, or automotive parts retailer that deploys video, audio, or text chat features on its website or in its product documentation should assess freedom-to-operate against US8402099B2. The patent's claim scope — covering communications between terminals via multimedia channels — is broad enough to implicate widely deployed customer engagement tools including live chat widgets, video support features, and interactive product guides.
Official order — verbatim text
The docket order reflects a Rule 41(a)(2) dismissal initiated by Defendant Carparts.com Inc with respect to its own counterclaims, with Plaintiff's lead counsel consenting following a court-ordered telephone conference. The order is procedural in nature and does not address the merits of either party's underlying infringement or invalidity positions. The recorded basis of termination is Dismissed Without Prejudice.
Dismissed without prejudice: what the outcome means for both parties
Dismissal without prejudice leaves claims legally alive
A dismissal without prejudice does not adjudicate the underlying infringement claims on their merits. Random Chat LLC retains the ability to refile suit on US8402099B2 against Carparts.com Inc, subject to applicable statutes of limitations and any separate agreement between the parties not disclosed in the public record. The dismissal here was entered under Fed. R. Civ. P. 41(a)(2) following a court-ordered telephone conference.
No merits ruling — claims surviveRandom Chat preserves its right to refile
As the plaintiff, Random Chat LLC retains all rights in US8402099B2 and is not barred from reasserting infringement claims against Carparts.com Inc or against other defendants. The dismissal without prejudice does not constitute an admission of invalidity or non-infringement of the asserted patent. Whether any commercial resolution accompanied the dismissal is not disclosed in the available record.
Patent enforceability preservedCarparts.com exits without prejudice — but exposure persists
Carparts.com Inc secured a dismissal without a finding of infringement, invalidity, or any monetary judgment against it. However, because the dismissal is without prejudice, Carparts.com cannot treat this outcome as a final resolution of its patent exposure on US8402099B2. Notably, Carparts.com's own counterclaims were also dismissed without prejudice at its request, with Plaintiff's lead counsel agreeing to those terms.
No liability finding — exposure remainsAutomotive e-commerce sites face unresolved multimedia chat IP risk
US8402099B2 covers multimedia video, audio, and text chat functionality — technology now widely deployed across e-commerce platforms, including in the automotive parts sector. The dismissal without prejudice signals that this patent's enforceability against web-based chat implementations has not been tested at trial or on summary judgment. Companies operating similar chat-enabled websites should assess their exposure to this patent independently.

What this case signals for the multimedia chat IP landscape
A dismissal without prejudice in a multimedia chat patent suit leaves enforcement questions unanswered and risk unresolved for the wider e-commerce sector.
US8402099B2 remains enforceable — the underlying IP risk is unresolved
No court has ruled on the validity or infringement scope of US8402099B2. Any e-commerce operator deploying video, audio, or text chat on its website — particularly in the automotive parts or retail sector — should treat this patent as an active risk and conduct a freedom-to-operate analysis before the next enforcement action.
Ramey LLP involvement signals a systematic assertion strategy
William P. Ramey III of Ramey LLP is among Plaintiff's counsel. Ramey LLP has a well-documented history of filing multiple patent infringement suits in Texas on behalf of patent assertion entities. This pattern suggests US8402099B2 may be part of a broader enforcement campaign targeting web-based communication features across multiple defendants.
