Patent Infringement and Invalidity Proceedings

We support you in patent infringement and invalidity proceedings when technical intellectual property rights must be consistently enforced or unfounded claims must be defended against. Whether a competitor is using your protected invention, whether you receive a cease-and-desist letter or a lawsuit, or whether a third-party patent restricts your freedom to operate in the market: We assess the technical and legal situation and work with you to develop a course of action that is robust and economically sound.

Delivering What Matters.

In patent infringement proceedings, the focus is on whether a product or method falls within the scope of protection of a patent and what claims arise from it. We assist you with analyzing the scope of protection, formulating arguments regarding acts of use, and evaluating circumvention solutions. At the same time, we keep the practical context in mind – in particular the preservation of evidence, time pressures in the market, and the question of which steps make sense in terms of enforceability and cost-benefit analysis.

Invalidity proceedings concern the validity of a patent. They serve to invalidate a patent in whole or in part if, for example, novelty or inventive step is lacking. Conversely, we represent patent holders in defending their intellectual property rights and in pursuing strategic limitations, provided this strengthens the patent’s validity.

Strategic advice backed by experience.

Since infringement and validity issues often overlap in practice, we closely coordinate both areas to ensure that arguments, motions, and timing are consistently aligned.

Our goal is to combine technical expertise with legal precision in such a way that your position in negotiations and proceedings remains clear, transparent, and enforceable – with the aim of securing your long-term competitiveness.
