Mere changes of name, i.e. changes that do not involve a modification of the legal identity of the applicant, can be entered in the European Patent Register upon request and production of relevant documentary evidence as long as the application (cf. A‑IV, 1.1.1) or the proceedings before the EPO are pending. Such registration is free of charge.
