IMC Créations, a French company specializing in anti-theft systems for vehicles, initiated a lawsuit against Mul-T-Lock France for infringing its unitary European patent EP4153830 related to high-security vehicle locks. IMC attempted to prove that Mul-T-Lock's MVP 1000 lock infringed claims 1, 2, and 7 of the patent. Subsequently, IMC sought to amend the patent claims to address Mul-T-Lock's counterclaims, which included a demand for nullity and a denial of infringement. The tribunal rejected various preliminary objections, with IMC revising their claims to focus on modifications in jurisdictions where the patent had unitary effect. Ultimately, the court sided with IMC Créations, highlighting the protective coverage of their patent claims 1 and 6, albeit after modification, in certain jurisdictions.
