(1) The German Patent and Trade Mark Office maintains a Register in which a record is kept of the titles of patent applications in respect of which file inspection is granted to any person, of patents granted and supplementary protection certificates (section 16a), as well as of the names and addresses of the applicants or proprietors of patents and of any representatives or persons authorised to accept service appointed pursuant to section 25, whereby the registration of one representative or person authorised to accept service suffices. The Register also records the commencement, expiry, lapse, order of limitation, revocation of patents and invalidity of supplementary protection certificates (section 16a), as well as the filing of a notice of opposition and a revocation action. The Register is also to include the date of entry of the unitary effect of the European patent notified by the European Patent Office and the notified date of entry into effect of the European patent with unitary effect pursuant to Article 4 (1) of Regulation (EU) No 1257/2012 of the European Parliament and of the Council of 17 December 2012 implementing enhanced cooperation in the area of the creation of unitary patent protection (OJ L 361, 31.12.2012, p. 1; L 307, 28.10.2014, p. 83).
(2) The President of the German Patent and Trade Mark Office may determine that further information be entered in the Register.
(3) The German Patent and Trade Mark Office records in the Register a change in the person, name or place of residence of the applicant or proprietor of the patent and his or her representative and the person authorised to accept service if proof thereof is furnished to the German Patent and Trade Mark Office. Until the change has been entered, the former applicant, proprietor of the patent, representative or person authorised to accept service remains subject to the rights and obligations as provided under this Act. If the person newly recorded in the Register as the applicant or proprietor of the patent takes over opposition proceedings before the German Patent and Trade Mark Office, opposition or appeal proceedings before the Federal Patent Court or proceedings on points of law before the Federal Court of Justice, the consent of the other parties to the proceedings is not required therefor.
(4) The German Patent and Trade Mark Office, at the request of the proprietor of the patent or licensee, enters in the Register the grant of an exclusive licence if proof of the consent of the other party is furnished to the German Patent and Trade Mark Office. The request referred to in sentence 1 is inadmissible in a case where the willingness to grant a licence has been declared (section 23 (1)). The entry is cancelled at the request of the proprietor of the patent or licensee. A request for cancellation made by the proprietor of the patent requires proof of the consent of the licensee designated upon entry or of the licensee’s successor in title.
