Andrejewski Honke – Germany 2021

JUVE Comment

This Essen-based IP firm is one of the best-known litigation outfits in western Germany on the patent attorney side. This is thanks to steady staff development over many years. Close ties to German companies strong in the technological sectors, such as auto suppliers Kiekert, TI Automotive and ThyssenKrupp, and bathroom manufacturer Kaldewei, lend the firm stability. The firm also files many patents for other regular clients like Novoferm, Certoplast and Hailo Wind Systems. Because Andrejewski Honke also conducted a number of opposition and nullity suits for these, the coronavirus pandemic did not impact the patent attorneys’ work too negatively, despite periods of reduced working hours in the auto industry. Their expertise is also called on by external lawyers for national infringement proceedings. Following slight growth last year, the firm did not expand further in the pandemic. The central challenge in any case is to prepare for the upcoming generation change in its core field, traditional mechanical engineering, with visible, younger partners.


Patent prosecution with technical expertise in engineering, especially for the automotive and sanitation industry.
