Eisenführ Speiser appoints Philipp Rastemborski as Equity Partner

Eisenführ Speiser continues to strengthen its partnership from within by appointing attorney-at-law and Certified IP Lawyer Philipp Rastemborski, LL.M. (Edinburgh) as Equity Partner.

Philipp Rastemborski advises our clients comprehensively on intellectual property law, with a particular focus on patent law, licensing, and antitrust matters. His core expertise lies in managing cross-border patent infringement litigation, IP-related arbitration, and parallel validity proceedings before national courts, the German Federal Patent Court, the European Patent Office, and the Unified Patent Court (UPC). His technical focus areas include medical technology, electronics, telecommunications, and computer-implemented inventions.

His appointment underscores our strategic commitment to supporting clients – many of whom are technology leaders in their industries – through fully integrated teams of patent attorneys and attorneys-at-law, delivering seamless, technically sophisticated advice “on eye level”. This approach has proven particularly effective in complex disputes before the newly established UPC.

We warmly congratulate Philipp Rastemborski and look forward to further strengthening our traditionally strong litigation practice together with Sönke Scheltz and Philipp Rastemborski as Equity Partners in our patent litigation team, ensuring we are positioned for long-term success in a challenging market environment.
