Johannes Heselberger

Dipl.-Phys.

Johannes Heselberger represents clients in patent infringement proceedings before German courts in the first and second instance and gives advice and support to them in legal appeal proceedings and in complaints against denial of leave to legal appeal proceedings before the German Federal Court of Justice.

In addition, Johannes Heselberger plays a leading and coordinating role in patent nullity proceedings before the German Federal Patent Court and in appeal proceedings before the German Federal Court of Justice as well as in opposition proceedings before the European Patent Office and the German Patent and Trademark Office.

Owing to his practice as an attorney-at-law and his qualification as a graduate physicist, Johannes Heselberger has comprehensive technical experience in the field of telecommunications, medical devices and the automotive industry. Pharmaceutical and biotech cases, including the extremely rare proceedings for a compulsory license, are also part of his field of practice as an attorney-at-law. His comprehensive professional expertise in SEP and FRAND litigations as well as in enforcement of and defense against license programs make him a precious advisor also in this field.

Johannes Heselberger successfully attended to a number of important, often transnational patent infringement proceedings for German and international large-scale companies as well as for owner-operated medium-sized enterprises. Depending on the size and complexity of a case, he heads compact teams of attorneys-at-law and patent attorneys or also large working groups in cooperation with his partners of the law firm.

Being qualified as both, an attorney-at-law (since 1994) and a European Patent Attorney (since 1999), he is particularly able to have a comprehensive understanding not only of the legal but also the technical aspects of a case. This enables Johannes Heselberger in a special way to coordinate infringement proceedings and proceedings on legal validity.
