Random Chat, LLC v. Lumen Technologies: Voluntary Dismissal in TCP/IP Multimedia Patent Case

Case Overview

In a case that closed almost as swiftly as it opened, Random Chat, LLC v. Lumen Technologies, Inc. (Case No. 2:25-cv-00968) concluded with a voluntary dismissal without prejudice just 105 days after filing in the Eastern District of Texas. The plaintiff, Random Chat, LLC, withdrew its TCP/IP multimedia communication patent infringement claims against Lumen Technologies, Inc. before the defendant had even filed an answer or moved for summary judgment — a procedural posture that carries significant strategic implications for both sides.

For IP professionals and patent litigators tracking network communications patent litigation, this case offers a concise but instructive example of how early-stage patent assertions in the Eastern District of Texas can resolve — or strategically retreat — before substantive engagement. The patent at issue, U.S. Patent No. 8,402,099 B2, covers a method for multimedia communication over network protocols, specifically TCP/IP and UDP, placing this dispute squarely within the increasingly active field of internet communications technology patent litigation.

The Parties

The Patent at Issue

This case involved U.S. Patent No. 8,402,099 B2, covering a method for multimedia communication based on network protocols, specifically TCP/IP and/or UDP:

• • U.S. Patent No. 8,402,099 B2 — A method for carrying out multimedia communication based on a network protocol, specifically TCP/IP and/or UDP.

Litigation Timeline & Procedural History

Random Chat, LLC filed suit on September 22, 2025, in the U.S. District Court for the Eastern District of Texas — a venue with a well-documented reputation for patent-plaintiff-favorable case management. The case was assigned to Chief Judge Rodney Gilstrap.

The case closed on January 5, 2026 — just 105 days after filing — on a voluntary dismissal filed by the plaintiff. Notably, at the time of dismissal, Lumen Technologies had not yet filed an answer or a motion for summary judgment. This places the dismissal squarely within Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure.

The Verdict & Legal Analysis

Outcome

On January 5, 2026, Chief Judge Rodney Gilstrap accepted and acknowledged the plaintiff’s Notice of Voluntary Dismissal. The Court ordered:

• • All claims by Random Chat, LLC against Lumen Technologies, Inc. dismissed without prejudice
• • Each party to bear its own costs, expenses, and attorneys’ fees
• • All pending requests for relief denied as moot
• • The Clerk directed to close the case

No damages were awarded. No injunctive relief was granted. The dismissal without prejudice means Random Chat, LLC retains the legal right to refile claims based on the same patent against Lumen or other parties, subject to applicable statutes of limitations and any strategic considerations.

Verdict Cause Analysis

The dismissal occurred before any substantive court rulings. Because Lumen had not yet answered the complaint, the plaintiff exercised its unilateral right under Federal Rule of Civil Procedure 41(a)(1)(A)(i) — a procedural mechanism that requires no court approval when exercised prior to an answer or summary judgment motion.

Common strategic drivers for pre-answer dismissals in patent litigation include: licensing negotiations progressing toward a settlement, claim scope reassessment, venue or strategy recalibration, or resource prioritization. The absence of an answer from Lumen suggests the defendant did not have the opportunity to raise formal invalidity defenses, counterclaims, or affirmative defenses on the record — a fact that may be strategically significant going forward.

Legal Significance

The “without prejudice” designation is the most legally consequential element of this outcome. Unlike a dismissal with prejudice — which operates as an adjudication on the merits and bars refiling — this dismissal leaves the patent’s enforceability against Lumen Technologies fully intact. Random Chat, LLC may reassert U.S. 8,402,099 B2 against Lumen or initiate new proceedings against other parties in the TCP/IP communications space.

Practitioners should note that a second voluntary dismissal against the same defendant would, under Rule 41(a)(1)(B), operate as a dismissal with prejudice — an important consideration for plaintiff-side strategy in any subsequent enforcement effort.
