Patent Enforcement in Monaco: OEHM, Tribunal and Superyacht Technology

TL;DR
Monaco enforces patents through civil suits before the Tribunal de Première Instance under Law No. 491 of 24 July 1968. Office de l'Expansion Economique de Monaco handles examination, grant, and nullity proceedings. Port Hercule superyacht refit yards generate stabilization fin and hybrid propulsion patent disputes. French validated European patents extend by treaty. See our France enforcement guide and Italy patent enforcement article by the PatentPaper research team.

OEHM Examination and Nullity Proceedings

Office de l'Expansion Economique examines applications, maintains the patent register, and hears nullity petitions on patentability and sufficiency grounds.

Example: A 2024 Tribunal interim injunction halted installation of active stabilization fin actuator assemblies whose hydraulic piston seal geometry matched OEHM-registered Dutch marine patents on a 90-meter superyacht refit at Port Hercule without authorization.

Tribunal Infringement Actions

Patent owners file civil suits seeking permanent injunction, compensatory damages, and customs detention at Monaco port for infringing marine spare parts.

Superyacht and Marine Technology

Port Hercule and Cap d'Ail refit yards face assertions on zero-speed stabilization fin patents, hybrid diesel-electric propulsion controller algorithms, and dynamic positioning joystick calibration method claims.

Formula One and Motorsport Engineering

Monaco Grand Prix supplier workshops encounter patent claims on carbon fiber monocoque layup method patents, kinetic energy recovery system flywheel designs, and active aerodynamic wing actuator geometries.

French European Patent Extension

European patents validated in France extend to Monaco by bilateral treaty, enabling direct Tribunal enforcement against Riviera marine distributors without separate Monaco validation.
