An assignment of a European patent application shall be made in writing and shall require the signature of the parties to the contract.

1) The transfer of a European patent application shall be recorded in the European Patent Register at the request of an interested party, upon production of documents providing evidence of such transfer. Rule 2, paragraph 2 [1] (regulating signing of the documents) shall apply mutatis mutandis to the signature of the parties to the contract.
