Scope of Protection Decisive in Utility Model Infringement: Safety Lock Case
Bakırköy 1st IP Court dismissed a utility model infringement claim for a safety lock, finding the defendant's product outside both literal and equivalent scope of protection. The counterclaim for invalidation was also dismissed.
Case Overview
A safety lock manufacturer sued a competitor for infringing its utility model. The defendant countersued for invalidation on novelty grounds. The case was remanded after two conflicting expert reports in the original proceedings.
Expert Panel Findings
- Main claim: Defendant's products do not fall within the utility model's claims literally or by equivalents.
- Packaging: Identical technical descriptions result from technical necessity, not unfair copying.
- Counterclaim: Utility model is novel and industrially applicable; invalidation conditions not met.
Outcome
Both claims dismissed. Utility model remains valid; no infringement established.
FAQ
What is the doctrine of equivalents?
A product may infringe even without literal claim correspondence if it achieves the same result by substantially the same means. The defendant's product failed even this broader test here.
