Random Chat, LLC v. Lamps Plus, Inc. — Dismissed With Prejudice in 153 Days
Random Chat, LLC asserted US8402099B2 — a patent covering multimedia video, audio, and text chat communication — against home lighting retailer Lamps Plus, Inc. in the Western District of Texas. The plaintiff voluntarily dismissed all claims with prejudice after just 153 days, before the defendant filed any answer or summary judgment motion.
Patent troll play against a retailer ends before defendant responds
On September 25, 2024, Random Chat, LLC filed a patent infringement action against Lamps Plus, Inc. in the U.S. District Court for the Western District of Texas (Case No. 7:24-cv-00242). The plaintiff asserted US8402099B2, a patent directed to facilitating multimedia communication — specifically video, audio, and text chat between terminals — alleging that Lamps Plus instructed its customers and related-company customers on how to use products and services embodying these claimed methods.
The case terminated on February 25, 2025, when the court acknowledged Random Chat’s February 24 Notice of Voluntary Dismissal With Prejudice filed under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Lamps Plus had not yet served an answer or a motion for summary judgment, the notice was self-effectuating under Fifth Circuit precedent — no court order was required to end the case. Each party was ordered to bear its own costs, expenses, and attorney fees, and all pending motions were denied as moot.
The 153-day lifespan and pre-answer dismissal are consistent with a pattern seen across many NPE-filed cases in the Western District of Texas, where early resolution — often following licensing discussions or defendant push-back — occurs before substantive litigation commences. The public record does not disclose whether a settlement or license was reached; the with-prejudice designation bars Random Chat from re-filing the same claims against Lamps Plus, but the underlying patent remains active and enforceable against other defendants.

Dismissed with prejudice: what Rule 41 means for both parties
Rule 41(a)(1)(A)(i): self-executing dismissal before answer
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may unilaterally dismiss an action without a court order by filing a notice before the defendant serves an answer or motion for summary judgment. Because Lamps Plus had not yet done either, Random Chat’s notice was self-effectuating — the Fifth Circuit describes such notices as terminating the case ‘in and of itself.’ The court’s order merely acknowledged the dismissal and disposed of pending motions as moot.
No merits adjudicationWith prejudice bars re-filing against Lamps Plus
A voluntary dismissal with prejudice operates as a final adjudication on the merits for purposes of res judicata. Random Chat cannot refile the same US8402099B2 claims against Lamps Plus in any federal court. This is materially different from a without-prejudice dismissal, which would preserve the right to refile. The public record confirms ‘with prejudice’ — the verdict text explicitly states this designation under Rule 41(a)(1)(A)(i).
Re-filing barred vs. Lamps PlusLamps Plus exits litigation without admitting liability
Lamps Plus achieved a clean exit: no answer filed, no validity or infringement ruling on the merits, and no damages exposure established on the public record. The each-party-bears-own-costs order means Lamps Plus absorbs its own legal fees — typical in pre-answer voluntary dismissals — but faces no fee-shifting exposure. Critically, the dismissal with prejudice permanently resolves this specific claim by this specific plaintiff.
No liability findingUS8402099B2 is still enforceable against other defendants
The with-prejudice dismissal only shields Lamps Plus. US8402099B2 — covering multimedia video, audio, and text chat communication between terminals — remains in force and can be asserted against any other party. Companies in e-commerce, retail tech, or customer-support communication tools who instruct users on chat-based interactions should treat this patent as an active enforcement risk. Random Chat’s litigation history via Ramey LLP suggests a broader assertion campaign may be ongoing.

Official order — verbatim text
The court’s order confirms a textbook Rule 41(a)(1)(A)(i) self-executing dismissal: because Lamps Plus had not served an answer or summary judgment motion, Random Chat’s notice required no judicial approval to terminate the case. The with-prejudice designation is plaintiff-chosen and legally significant — it forecloses any future action by Random Chat on the same patent claims against Lamps Plus. The own-costs ruling is the court’s only affirmative exercise of discretion, declining to shift fees in either direction. No infringement, validity, or damages determination was made.
US8402099B2 — Multimedia video, audio, and text chat communication
US8402099B2 (application number US12/675046) covers systems and methods for facilitating multimedia communication — specifically video, audio, and text chat between terminals. The patent is directed to the orchestration layer that enables real-time multi-modal communication sessions, a technology domain that became commercially critical with the rise of web-based customer engagement platforms, live chat tools, and video support systems. The corrected application number suggests prosecution history worth reviewing for claim scope.
For the retail and e-commerce sector, this patent is strategically relevant because modern omnichannel retailers routinely deploy chat widgets, video consultation tools, and audio-support features on their websites — squarely within the instructional-use theory Random Chat advanced against Lamps Plus. The NPE model here targets not the technology vendor but the retailer deploying the tool, a claim construction approach that significantly broadens the universe of potential defendants and raises the cost of defending on the merits.
Should you run an FTO against US8402099B2?
Any company operating customer-facing multimedia chat features — including video consultation, live chat, audio support, or co-browsing — should consider a freedom-to-operate review against US8402099B2. The claim theory advanced in this case targets parties who instruct customers on how to use such tools, not just technology developers. Retailers, SaaS platforms, and financial services firms with embedded communication features are particularly exposed given the breadth of the instructional-use allegation.

Early FTO analysis is significantly cheaper than defending a Western District of Texas NPE suit — even one that resolves pre-answer.

What this case signals for the multimedia chat patent IP landscape
A pre-answer dismissal in the Western District of Texas rarely signals strength — it signals leverage exhausted or a quiet deal struck.
Pre-answer dismissal in W.D. Tex. typically signals NPE leverage play
Cases filed by NPEs via Ramey LLP in the Western District of Texas that resolve before the defendant answers are consistent with demand-letter or early licensing campaigns. The absence of any merits ruling means Lamps Plus neither validated nor invalidated the patent — leaving US8402099B2 as an ongoing tool for Random Chat against other targets in the multimedia communication space.
Retailers using chat or video tools face residual US8402099B2 exposure
The asserted claims target parties who instruct customers on using multimedia chat — video, audio, or text communication between terminals. Any e-commerce or retail company deploying customer-facing chat, video support, or co-browsing tools should assess whether their implementation falls within the claim scope of US8402099B2 before receiving a demand letter.
Random v Lamps — key questions answered
Random Chat, LLC filed patent infringement claims against Lamps Plus, Inc. in the Western District of Texas on September 25, 2024, asserting US8402099B2 covering multimedia chat communication. The plaintiff voluntarily dismissed all claims with prejudice on February 24, 2025, under Rule 41(a)(1)(A)(i), before Lamps Plus filed any answer. Each party bore its own costs.
A dismissal with prejudice operates as a final adjudication on the merits for res judicata purposes. Random Chat is permanently barred from re-filing the same US8402099B2 claims against Lamps Plus in any federal court. The patent itself remains enforceable, but this specific plaintiff cannot reassert it against this specific defendant.
Yes. The with-prejudice dismissal only protects Lamps Plus. US8402099B2, covering multimedia video, audio, and text chat between terminals, remains active and enforceable against any other defendant. Companies deploying customer-facing chat or video tools should assess their exposure to this patent independently of the Lamps Plus outcome.
Random Chat was represented by William P. Ramey III and Jeffrey Eugene Kubiak of Ramey LLP, a firm with an extensive NPE litigation docket in the Western District of Texas. Lamps Plus was represented by Jennifer Klein Ayers of Sheppard Mullin Richter & Hampton LLP.
Rule 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without a court order by filing a notice before the defendant serves an answer or summary judgment motion. Because Lamps Plus had not yet done either, Random Chat’s notice was self-effectuating under Fifth Circuit precedent — the court’s acknowledgment order was confirmatory only. The rule gave Random Chat full control over the exit terms, including the with-prejudice designation.
