Juve’s current handbook identifies Grünecker as one of the most active filing firms at the European Patent Office. The "large prosecution practice" handles intellectual property rights over a broad technical spectrum. The automotive and chip industries have long entrusted Grünecker with applications and oppositions, writes Juve. Juve mentions Harman Becker, Fuji, Krones, Lear Corp., Mahle, Microsoft, Nissan, Panasonic, Rockwell, Samsung, Tyco and Yamaha as some of Grünecker’s clients.

Clients and competitors often recommend the Grünecker patent attorneys Martin Aufenanger, Dr. Moritz Höffe, Reinhard Knauer, Thomas Schuster and Dr. Heike Vogelsang-Wenke.
