Entries and data recorded in the register

Transfer of rights (data concerning the new owner), licences (licensee's name, duration of the contract, exclusivity, limitation on certain claims if applicable), mortgage (name of the mortgagee), the fact that the right to a patent is or the rights conferred by a patent are part of a trust.

Requests for recording rights or data in the register must be made in writing. An official or private document providing sufficient evidence must be attached to the request. The HIPO amends the register data concerning the inventor and the share in authorship on the basis of either a unanimous declaration of all inventors recorded in the register and all of the persons making the request or a final court decision attached to the request. Where requests on the same case are mutually exclusive, they are dealt with in order of date of receipt.

The patent register authentically attests to the existence of the rights and facts recorded therein, in the absence of proof to the contrary. If their correctness or authenticity is disputed, the burden of proof is on the person doing so.

With the exception of mortgage, entry in the register of transfer of rights, the fact that the right to a patent is or the rights conferred by a patent are part of a trust, and licences has declaratory effect.

Any patent-related right has effect vis-à-vis a third party acquiring it in good faith and for a consideration only if it has been recorded in the patent register.

Any person may have access to the patent register. The register is accessible electronically (online) via the HIPO website. Subject to payment of a fee, any person may ask for a certified copy of the data recorded in the register.

Art. 54, 55, 25(2) PA



Is a transfer registered by the EPO under Rule 85 EPC recognised?
