Random Chat LLC v. Amazon.com: Multimedia Chat Patent Suit Dismissed in 98 Days
Random Chat, LLC filed suit against Amazon.com in the Western District of Texas asserting US8402099B2, a patent covering multimedia video, audio, and text chat between terminals. The case ended in a voluntary dismissal without prejudice after just 98 days — before Amazon filed any answer or dispositive motion.
Pre-Answer Dismissal Keeps Multimedia Chat Patent Live Against Amazon
On January 14, 2025, Random Chat, LLC filed a patent infringement action against Amazon.com, Inc. in the Western District of Texas (Case No. 7:25-cv-00011) before Judge Alan D. Albright. The suit asserted US8402099B2, which covers multimedia communication technology — specifically video, audio, and text chat between terminals — and targeted Amazon’s website and product instruction materials relating to those capabilities.
On April 22, 2025, just 98 days after filing, Random Chat filed a Rule 41(a)(1)(A)(i) notice of voluntary dismissal. Because Amazon had not yet filed an answer or a motion for summary judgment, the plaintiff was entitled to dismiss as of right, without requiring court approval. Critically, the dismissal was entered without prejudice as to the asserted patent, meaning Random Chat retains the ability to reassert US8402099B2 against Amazon or other defendants in the future. Each party bears its own costs and fees.
A dismissal occurring this early — before Amazon’s counsel at White & Case LLP had formally responded on the merits — is consistent with several scenarios: ongoing licensing negotiations, a decision to re-file in a different venue, or a strategic pause ahead of claim refinement. The public record does not disclose whether any commercial agreement was reached. What is clear is that the without-prejudice designation preserves Random Chat’s full enforcement options, and the case’s short duration in Judge Albright’s court suggests the dispute did not advance beyond early procedural stages.

Voluntarily dismissed without prejudice: what the ruling means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right, no court order needed
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss an action without a court order at any time before the defendant serves an answer or a motion for summary judgment. Amazon had done neither, so Random Chat’s notice was self-executing. This is the cleanest procedural exit available — no judicial approval, no merits ruling, and no collateral estoppel consequences from this case.
Procedural exit — no merits adjudicatedWithout prejudice preserves every future enforcement option
A dismissal without prejudice means the claims are not finally resolved — Random Chat can refile the same patent against Amazon or any other party. A dismissal with prejudice would have permanently barred Random Chat from reasserting these claims against Amazon. The notice here expressly states the dismissal is ‘WITHOUT PREJUDICE as to the asserted patent,’ removing any ambiguity. The public record is silent on whether a settlement or licensing arrangement underlies this choice.
Patent remains enforceableAmazon exits without conceding liability or paying a judgment
Amazon.com, represented by White & Case LLP, avoided any merits determination. No answer was filed, no invalidity or non-infringement arguments entered the public record, and no fee award was made against either party. While Amazon bears no immediate financial consequence, the without-prejudice dismissal means it faces continued exposure to re-filed claims on US8402099B2 — potentially in a different venue or after claim-mapping refinement by the plaintiff.
No admission, but exposure persistsEarly dismissal signals unresolved risk for multimedia chat platforms
US8402099B2 remains an active, enforceable patent. Companies operating video, audio, or text chat platforms — particularly those who instruct users through web interfaces or product manuals — should monitor this patent closely. The pre-answer dismissal without prejudice is consistent with a plaintiff that intends to continue enforcement activity. Judge Albright’s Western District of Texas docket remains a favoured venue for patent assertion, adding further strategic relevance for potential defendants in this technology space.

Official order — verbatim text
The voluntary dismissal notice invokes Rule 41(a)(1)(A)(i) precisely because Amazon had not yet answered — making this a self-executing procedural step, not a court-ordered outcome. The express ‘WITHOUT PREJUDICE as to the asserted patent’ language is legally significant: it forecloses any argument that the dismissal bars future enforcement of US8402099B2. The mutual fee-bearing arrangement is standard for pre-answer dismissals and does not imply any concession by either party.
US8402099B2 — Multimedia Video, Audio, and Text Chat Between Terminals
US8402099B2 (application number US12/675046) protects multimedia communication technology covering the establishment and operation of video, audio, and text chat sessions between terminals and related systems. The patent sits at the intersection of real-time communications and networked terminal infrastructure — a domain that has grown substantially with the proliferation of web-based and mobile communication platforms. Its application date places it in an era predating the mainstream adoption of WebRTC and modern unified communications stacks, potentially giving its claims priority over widely deployed implementations.
For any company operating a consumer or enterprise-facing chat, video conferencing, or unified communications product, US8402099B2 represents a monitoring priority. Random Chat’s decision to assert it against one of the world’s largest technology companies — and to dismiss without prejudice, preserving all enforcement options — suggests confidence in the patent’s claim scope and potential licensing value. Competitors in the real-time communications, customer support chat, and video collaboration sectors should evaluate their exposure, particularly where products instruct users through web interfaces or documentation.
Should your product team run an FTO against US8402099B2?
Any organisation building, deploying, or licensing video, audio, or text chat functionality — including WebRTC-based platforms, VoIP services, customer support chat tools, or unified communications products — should consider a freedom-to-operate assessment against US8402099B2. The patent has been actively asserted against Amazon, and its without-prejudice dismissal means it remains fully enforceable. If your product instructs users on multimedia communication through web pages or manuals, you may fall within the asserted claim scope.
PatSnap Eureka’s FTO Search Agent enables R&D and IP teams to map product features against the claims of US8402099B2, surface relevant prior art that may support invalidity arguments, and identify design-around opportunities before litigation pressure mounts. With Random Chat’s enforcement posture suggesting continued activity, proactive clearance now is significantly less costly than reactive defence after a new complaint is filed.

The venue choice by Random Chat, represented by Ramey LLP, is consistent with an assertive enforcement strategy targeting a large technology defendant.
Not necessarily. Each party bearing its own costs is the default outcome under Rule 41(a)(1)(A)(i) pre-answer dismissals and does not, by itself, indicate a settlement or licensing agreement. The public record is silent on whether any commercial arrangement was reached. The absence of any fee-shifting award is consistent with this being a standard procedural dismissal rather than a negotiated resolution.
