Your intellectual property lawyers

In the field of intellectual property, enforcing patent and trademark rights for patent proprietors or defending against unjustified attacks are often essential to a company’s financial performance.

For 50 years, we have given our clients outstanding advice and conducted successful litigation on their behalf.

Wildanger - decisively different.

Uncompromisingly good

WILDANGER stands for excellence in advice and litigation, particularly in the field of patents and trademarks. Our clients appreciate our unique expertise and strategic creativity. Handling intellectual property cases can often be like a game of chess. It is essential to take a proactive approach and to anticipate possible steps and strategies of the opponent. Where others stop thinking, we take the necessary next step.

Notably experienced

National and international clients trust our solid advice and many years of experience in litigation. For decades, WILDANGER has been involved in landmark decisions in intellectual property matters. This is tangible proof of our outstanding legal expertise and ingenuity.

Genuinely personal

The key benefit of our law firm and its organization is the way in which we treat our clients and their issues. All of our clients know that they will receive personal service from experienced partners instead of being “handed down” to a junior employee. As skilled and reliable partners, we will accompany you on your way and handle your case effectively – every step of the way.

Case Study „Patente – SEPs/FRAND“

WILDANGER regularly advises and represents owners, but also implementers of standard essential patents (SEP).

For example, WILDANGER advised a SEP owner on the preparation and enforcement of a licensing campaign for patents relating to audio compression and represented him in court proceedings. In the context of this campaign, WILDANGER has obtained several injunctive relief judgements for its client against manufacturers and distributors of patent infringing mobile phones before the Regional Courts of Mannheim and Düsseldorf. Furthermore, WILDANGER, together with the patent attorneys involved, has defended the patents asserted in the nullity actions brought against them. As a result of the judgments obtained in the infringement proceedings, the asserted SEPs could be successfully exploited commercially.

WILDANGER’s activities are not limited to the judicial enforcement of SEPs. WILDANGER also provides comprehensive advice on the development of licensing strategies and the preparation of FRAND offers or counter offers. Accordingly, WILDANGER´s clients include SEP owners, but also implementers.
