The Verdict & Legal Analysis
Outcome
On **January 2, 2026**, the Eastern District of Texas accepted Plaintiff Random Chat, LLC’s **Notice of Voluntary Dismissal** (Dkt. No. 15), dismissing all claims **without prejudice** pursuant to **Federal Rule of Civil Procedure 41(a)(1)(A)(i)**. No damages were awarded, no injunctive relief was granted, and each party was ordered to bear its own costs.
Verdict Cause Analysis
The dismissal was procedural, not merits-based. Samsung had not yet filed an answer or moved for summary judgment. This swift voluntary withdrawal likely occurred during the early pleadings phase, suggesting pre-answer licensing negotiations were unsuccessful, Samsung signaled robust invalidity defenses (e.g., potential Inter Partes Review or § 101 challenges), or the plaintiff reassessed its assertion strategy. The “without prejudice” designation means Random Chat, LLC retains the right to re-file claims based on the same patent.

The case involved U.S. Patent No. 8,402,099 B2 (Application No. US 12/675,046), covering a method for carrying out multimedia communication based on network protocols including TCP/IP and/or UDP.
Plaintiff Random Chat, LLC filed a voluntary dismissal of all claims without prejudice pursuant to FRCP 41(a)(1)(A)(i). Samsung had not yet filed an answer, making dismissal available as of right. The court accepted the dismissal on January 2, 2026, with each party bearing its own costs.
Yes. A dismissal without prejudice does not bar re-filing. However, any subsequent action would be subject to applicable statutes of limitations, and defendants may raise additional defenses based on the litigation history.
