Wildanger Kehrwald Graf von Schwerin & Partners mbB is one of the oldest and most prominent German IP litigation firms in Germany and can rely on decades of experience. Wildanger has an outstanding position in the field of patent litigation and is well-known for its drive and extraordinarily high standards. Wildanger has 13 truly-specialized attorneys in IP litigation – among them 9 partners. The firm’s international and national clients always receive the same level of dedication and individual attention. 

Wildanger has a remarkable and most successful track record in SEP enforcement and licensing, as well as in handling any sort of IP-litigation across industries at any level of complexity.

The firm was already focused on IP law when it was taken over in 1967 by Günther Wildanger, one of Germany’s best-known patent litigation attorneys. It played a decisive role in establishing Dusseldorf as a leading jurisdiction for patent and utility model litigation. A very high number of leading German decisions in the field of IP law, in particular patent law, involved cases handled by Wildanger.

All partners have set themselves apart in their own personal ways through their outstanding work, expertise and experience. They hold themselves to extremely high standards. The close-knit team of internationally experienced attorneys works closely together, sharing their knowledge and expertise – with effective results. The firm’s team is freely “scalable” to handle even large and complex litigation.
