Patent prosecution in Germany

Bardehle Pagenberg

Bardehle Pagenberg continues to be a leading advisor in the automotive, telecoms, software and electronics sectors, but is also very visible in its assistance to clients from the life sciences industry, engineering specialists and sports article manufacturers. With its set-up as a mixed patent law and attorney-at-law firm, the practice has managed to accumulate a wealth of experience in advising on simultaneous opposition, infringement and nullity proceedings. With its German offices in Munich and Düsseldorf, its own international presence in Paris, Verona and Barcelona as well as with a reliable network of international firms, particularly in the US and Asia, the team advises both on purely German as well as on cross-border matters. Its offering of language services and its in-house graphic designer stand out within the German market. Johannes Lang, who is managing partner alongside lawyer and patent lawyer Johannes Heselberger, jointly heads the practice with Christof Karl, Joachim Mader and Tobias Kaufmann, who are all also experienced in advising on patent disputes and patent infringement proceedings. In January 2020, Hans Wegner changed his position to of counsel.


' I especially appreciate the team approach. At Bardehle, as a client, you don't have the feeling of working with an external law firm, but rather together within a team. This is very important, because only with mutual understanding and the resulting synergy are exceptional services possible. The cooperation is characterized by a pragmatic approach in which communication is open and nothing is 'nicely talked'. The strategic support in the registration and examination processes at Bardehle is recognized by the very high level of commitment of the lawyers involved and the support team. '

' Joachim Mader: I really like his pragmatic and team-oriented approach and one of his particular strengths is strategic advice. '

' Proactivity and the speed of actions and reactions are certainly unique. From my point of view, this also shows the technical competence and comprehension. '

' Competent, very reliable in cooperation, committed, easy to reach, friendly in communication. '
