JUVE Patent

Gassauer-Fleissner – Austria 2020

JUVE Comment

The IP practice of this Vienna-based firm is a leading outfit with a strong presence in almost all significant Austria-related pharmaceutical proceedings. It is the most renowned outfit throughout Austria and Europe for patent litigation. When it comes to trademarks and unfair competition, the lawyers are increasingly building a profile in advice to trademark owners. Nevertheless, its reputation for soft IP does not come close to the practice’s exceptional standing for patents and know-how protection. The team around Christian Gassauer-Fleissner, a luminary in Austrian patent law, consistently advises originator drug manufacturers on important pharmaceutical patents, including how to extend their protection. To reduce the team to its extensive work in pharmaceuticals, however, would be a mistake. IT companies and traditional mechanics patents now also play a role. The firm’s comprehensive advice to a manufacturer of safety controls for autonomous cars demonstrates how the younger partners are increasingly incorporating aspects of technology, copyright and IT law, as well as know-how protection, into their advisory services. Unlike other boutiques, the IP team under Christian Gassauer-Fleissner has already established the next generation of partners who are ready to follow in the senior partners’ footsteps, one example being Dominik Göbel. This younger generation is also developing their own business in soft IP and other patent-related areas. That said, the firm is constantly battling the revolving door, as indicated by the departure of a lawyer in mid-2018. Team stability is a necessity if the firm is to branch out from its strong focus on patents.


Strategic advice and litigation, specialisation in pharma patents, know-how protection.
