The Verdict & Legal Analysis
Outcome
On February 6, 2026, Guangzhou Youlan Technology Co. Ltd. filed a voluntary dismissal without prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A). The dismissal affected the entire action against Defendant Onbrill World. No damages were awarded. No injunctive relief was entered. No merits determination was made by the court.
A Rule 41(a)(1) dismissal without prejudice means the plaintiff retains the right to refile the same claims against the same defendant in the future, subject to applicable statutes of limitations and any applicable “two-dismissal rule” under FRCP 41(a)(1)(B).
Key Legal Issues
Because the dismissal occurred voluntarily and without a merits ruling, the court issued no findings on: **Validity** of USD1075331S, **Infringement** under the Egyptian Goddess ordinary observer standard, **Claim scope** or any claim construction determinations, or **Damages** calculations under 35 U.S.C. § 289. The absence of any defendant agent on the record is particularly telling, suggesting that Onbrill World either did not respond to service or early-stage communications.
