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.
