Case Overview
The Parties
⚖️ Plaintiff
A China-based manufacturer widely recognized in the global vaping and electronic cigarette industry, actively enforcing its IP portfolio.
🛡️ Defendant
A U.S.-based wholesale distributor of various consumer products, including vaping devices.
The Patent at Issue
The asserted patent is U.S. Design Patent No. USD1,080,989S (Application No. 29/939,702). Design patents under 35 U.S.C. § 171 protect the ornamental appearance of a functional article — in this case, the visual design of a disposable vaping device.
- • US D1,080,989S — Ornamental design for a disposable vaping device.

The Verdict & Legal Analysis
Outcome
On January 7, 2026, Shenzhen Kanger Technology voluntarily dismissed the action without prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). This procedural mechanism allows a plaintiff to dismiss a case unilaterally before the defendant serves an answer or a motion for summary judgment — requiring no court order and leaving the plaintiff free to re-file the same claims in the future. No damages were awarded, and no injunctive relief was granted.
Verdict Cause Analysis
The dismissal “without prejudice” under Rule 41(a)(1)(A)(i) is legally significant for what it does not foreclose. Kanger retains the right to re-file the same infringement claims, assert the same design patent against other parties, or pursue the matter after additional investigation or negotiations. The absence of filed defense counsel is a critical data point, suggesting R&M Wholesale may not have formally appeared, which can accelerate or reframe plaintiff’s strategic calculus. Alternatively, the dismissal may reflect a private settlement or licensing agreement reached outside the court record.
Legal Significance
Because the case terminated without a judicial ruling, it carries no precedential value on the merits of design patent infringement in the disposable vape space. However, the filing itself — backed by Am Law 100 counsel and targeting a wholesale distributor — signals Kanger’s willingness to pursue downstream distribution channels, not merely manufacturers or direct competitors.

U.S. Design Patent No. USD1,080,989S (Application No. 29/939,702), covering the ornamental design of a disposable vaping device.
Plaintiff Shenzhen Kanger Technology voluntarily dismissed under F.R.C.P. 41(a)(1)(A)(i) before the defendant answered. No court ruling on the merits was issued; the dismissal preserves Kanger’s right to re-file.
It reinforces the use of design patents as enforcement tools against U.S. distributors of foreign-manufactured vaping products, signaling heightened IP risk for wholesale channels in this market segment.
