Case Overview
The Parties
⚖️ Plaintiff
A global leader in non-invasive aesthetic and wellness technologies, known for its EMFACE® and EMSCULPT® devices.
🛡️ Defendant
An aesthetic service provider or device operator, named alongside co-defendants Terra Jeffery and Chloe Jeffery.
The Patents at Issue

The Verdict & Legal Analysis
Outcome
BTL Industries voluntarily dismissed this action **with prejudice** pursuant to **Federal Rule of Civil Procedure 41(a)(1)(A)(i)**. This closure occurred after the defendant failed to answer the complaint, resulting in no judicial ruling on the merits, no damages award, and no injunctive relief granted by the court.
Legal Significance
The **with-prejudice** dismissal signifies that BTL cannot refile identical claims against these defendants, suggesting the underlying dispute was resolved to BTL’s satisfaction without requiring a default judgment or contested litigation. This mechanism allows plaintiffs to lock in resolution terms privately and avoid public contested rulings. For the asserted patents (US11,878,167 and US11,679,255), no adverse claim construction or validity findings were entered, preserving their full enforceability for future assertions. The defendants’ failure to answer points to a potential lack of litigation resources or early cessation of the allegedly infringing activity.

Two U.S. patents: US11,878,167 (EMFACE® facial contouring technology) and US11,679,255 (EMSCULPT® body contouring technology), filed under Application Nos. 17/664,161 and 17/930,888 respectively.
BTL voluntarily dismissed under FRCP 41(a)(1)(A)(i) after defendants never answered the complaint. A with-prejudice dismissal suggests the underlying enforcement objective — likely cessation of infringing activity — was achieved through private resolution.
It reinforces BTL’s active enforcement posture in the electromagnetic aesthetic device market and signals that smaller operators deploying competing devices face material litigation risk, regardless of company size.
