The Verdict & Legal Analysis
Outcome
The ITC entered a **violation finding in favor of Inovate Acquisition Corporation**, with the basis recorded as judgment on the merits.

Key Legal Issues
The investigation centered on whether Xiamen Dirongte’s imported exhaust vent doors infringed valid and enforceable claims of US11953230B2. The violation finding implies Inovate successfully established a domestic industry, infringement, and importation.
