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.

Wildanger operates at the forefront of innovation, working with companies technologies such as biochemistry, software, information technology, semiconductor technology and telecoms, as well as in classic areas, including pharmaceuticals, chemicals, engineering, automotive, medical technologies, consumables, electronics and electrical engineering.
