The Verdict & Legal Analysis
Outcome
On April 26, 2024, Winner’s Sun Plastic & Electronic (Shenzhen) Co. Ltd. filed a voluntary dismissal with prejudice against defendant OEM Tech Bargains, LLC (a/k/a CamKix, a/k/a Eco-Fused) pursuant to Rule 41(a) of the Federal Rules of Civil Procedure. The dismissal stipulated that all parties bear their own costs and attorneys’ fees. No damages award was entered, and no injunctive relief was granted. The resolution was entirely procedural, with no judicial determination on the merits of infringement or patent validity.
Key Legal Issues
The resolution reflects a voluntary dismissal with prejudice under Rule 41(a) of the Federal Rules of Civil Procedure. This indicates a mutual walk-away arrangement, where the plaintiff is permanently barred from re-filing the same claims against this defendant based on US9995993B2, without any judicial determination on the merits of the asserted patent or infringement. This legal outcome underscores the procedural complexities and economic considerations often present in patent enforcement campaigns against e-commerce sellers.

U.S. Patent No. US9995993B2 (Application No. US14/759691), covering selfie device technology.
Plaintiff Winner’s Sun filed a voluntary Rule 41(a) dismissal with prejudice. No court-determined reason was disclosed; the dismissal may reflect settlement, litigation economics, or strategic reconsideration. All parties bore their own costs.
The case leaves Patent No. US9995993B2’s claim scope judicially unconstrued, meaning future enforcement actions by Winner’s Sun against other defendants remain legally viable, subject to applicable statutes of limitations and procedural considerations.
