Rule 22 Registration of transfers

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, shall apply mutatis mutandis to the signature of the parties to the contract.

Registration of the transfer may be subject to the payment of an administrative fee under the conditions laid down by the President of the European Patent Office. Where a fee is due, the request shall not be deemed to have been filed until the administrative fee has been paid. It may be rejected only if paragraph 1 has not been complied with.

A transfer shall have effect vis-à-vis the European Patent Office only at the date when and to the extent that the documents referred to in paragraph 1 have been produced.
