JUVE Patent

Keil & Schaafhausen – Germany 2018

JUVE Comment

This IP firm has an excellent reputation as a prosecution outfit in Frankfurt and the surrounding area. The patent attorneys are also active for regular clients in opposition and nullity suits. K&S recently grew by several patent attorneys, partly due to the merger with Frankfurt firm Dr. Knoblauch. Dr. Andreas Knoblauch brings experience in mechanics and electronics patents. His regular clients include ASC Telecom, Danfoss and Karl Mayer Textilmaschinen. The work of K&S itself is heavily characterized by filing for long-time clients from the engineering, mechanics, chemicals and chemical engineering sectors. K&S conducts infringement proceedings with both its own lawyers and external litigators, but its visibility cannot compete with that of the Düsseldorf or Munich firms. This may change after the merger with Dr. Knoblauch with the new clients this brings. The greater focus on Chinese work pushed by a patent attorney with a Chinese background harbors further potential.
