Case Overview
The Parties
⚖️ Plaintiff
An individual patent holder asserting rights in a rotating rack design.
🛡️ Defendant
A litigation placeholder commonly used when plaintiffs identify multiple sellers whose true identities may be concealed behind marketplace storefronts.
Patents at Issue
This case centered on design patent USD1047592S (Application No. US29/917809), covering a **rotating rack** product. Design patents are registered with the U.S. Patent and Trademark Office (USPTO) and protect ornamental appearance rather than functional technology.

The Verdict & Legal Analysis
Outcome
Plaintiff Kundian Guo voluntarily dismissed the action without prejudice pursuant to Fed. R. Civ. P. 41(a)(1)(A)(i). No damages were awarded, no injunctive relief was granted, and no merits determination was made. The without-prejudice designation preserves Guo’s right to refile claims against these or related defendants in the future, subject to applicable statutes of limitations and procedural rules.
Key Legal Issues
Because the case was dismissed at the pre-answer stage, no claim construction ruling, validity challenge, or infringement finding was issued by the court. The legal record is procedurally thin by design. Critically, the without-prejudice dismissal means:
- • No res judicata effect bars future litigation on the same claims
- • No adverse merits ruling weakens the patent’s enforcement posture
- • Defendants received no formal exoneration
The strategic rationale behind voluntary pre-answer dismissal in Schedule A cases often includes: resolution through private settlement, inability to identify or serve specific defendants, or reassessment of litigation strategy following the filing and any TRO proceedings.
