The Register of European Patents, containing the particulars specified in Rule 92, may be consulted in order to ascertain the state of the proceedings and the legal status of patent rights. Entries are made in the Register of European Patents up to expiry of the period of opposition or the termination of opposition proceedings. The only exception is the correction of the designation of the inventor, which is made at any time. The Online European Patent Register via the Internet (www.epoline®.org) can be accessed free of charge. Apart from the data entered in the Register of European Patents, the Online Register includes additional application and procedural data not published in the European Patent Bulletin. Register data may also be obtained by telephone from the Information Offices in Munich, The Hague, Berlin or Vienna.
