He is a certified specialist for intellectual property law (“Fachanwalt für gewerblichen Rechtsschutz”) and specialises on the law of technical protective rights, i.e. patent law and utility model law as well as the associated areas of law, especially copyright law and the law of unfair competition.


His practice includes advising and representing clients in all matters relating to inventions and know-how as well as copyright, from litigation to the negotiation of licence agreements and technology transactions. In the field of technical protective rights he is active across the entire scientific spectrum, in particular in the areas of life sciences, automotive, software/IT and electronics.

Dr Stjerna has repeatedly represented constitutional complaints before the German Federal Constitutional Court (“BVerfG”). In response to his constitutional complaint, the BVerfG declared null and void the German ratification of the international Agreement on a Unified Patent Court in March 2020, for the first time granting a right to “formal control” in respect of the transfer of sovereignty rights (docket no. 2 BvR 739/17, cf. also here).
