Display monitor (Federal Supreme Court)

Federal Supreme Court (BGH), judgment of 27.6.2023 - X ZR 59/21

Law applied:

Patent Act Sec. 81, Sec. 121 (2)

Code of civil procedure (ZPO) Sec. 93

Summary:

  1. A patent owner gives cause for filing a nullity action if, despite being requested to do so, it does not provide the potential nullity plaintiff with a legal position comparable to that after the patent has been declared invalid prior to filing the action (confirmation of Federal Supreme Court (BGH), judgment of August 13, 2013 - X ZR 73/12, GRUR 2013, 1282 para. 50 - Druckdatenübertragungsverfahren).
  2. A prior request on the part of the nullity action plaintiff is not already dispensable because the patent owner has indicated in the course of licensing negotiations that it will not avoid litigation.
