Stefan Demmel

Patent attorney | Munich

Patent Litigation

„Franck Klein also offers up his expertise on this mandate and earns praise from another satisfied patron for being “extremely skilled, open minded and collaborative. He takes the time to discuss matters in person, which speeds up the process and brings in better results thanks to the exchange of information and brainstorming that happens during such conversations. Franck is also proficient in all three official languages of the EPO, so he grasps the nuances of language used in patent applications and can propose new arguments in opposition proceedings on this basis.“

– IAM Patent 1000 Guide 2024
