Bardehle Pagenberg

Bardehle Pagenberg is particularly known for its strength in the automotive, telecommunications, software and electronics industries, but has also gained a very good reputation in the mechanical engineering, medical technology, pharmaceuticals and sporting goods sectors. The IP boutique, headquartered in Munich and with additional offices in Düsseldorf, Paris and Barcelona, provides patent law and attorney-at-law advice from a single source, which, in addition to its highly regarded expertise in prosecution matters, also equips the firm with particular clout in infringement proceedings. The team assists with patents, utility models and employee inventions and also offers many years of experience in design protection. The range of services further includes strategic portfolio advice and representation in proceedings before German and international patent offices, especially in opposition and nullity proceedings. Hereby, the team is just as well versed in handling purely German instructions as its is in advising on cross-border patent prosecution, in the context of which it can also rely on established international partner law firms. The practice is particularly active in matters relating to the US and Asia, while its cooperation with Singapore law firm Yusarn Audrey LLC underlines the firm’s international orientation. Johannes Lang (computer and electrical engineering, telecommunications, semiconductor technology), Christof Karl (computer hardware and software), Joachim Mader (mechanical engineering and process engineering), Tobias Kaufmann (electrical engineering, IT, medical technology) and Georg Anetsberger (lasers – and semiconductor physics among others) jointly lead the team.


‘The coordination and cooperation in and with the team around Johannes Heselberger as well as the cooperation with other patent attorneys in patent infringements matters is essential for our company, which is determined by its own innovations.’

Johannes Heselberger has been valuable for many years in out-of-court, but above all in in-court representation in the event of patent infringements.’
