We represent our clients in Post Grant Proceedings, i.e. opposition, infringement and validity, before the UPC, EPO, GPTO, and German Federal Patent Court . We assist in coordinating the infringement proceedings in Europe with ongoing infringement proceedings in the United States.

Legal opinions

Our clients frequently rely on us to analyze EP and DE intellectual property rights. We assess their validity and investigate potential infringements - often in the context of freedom-to-operate (FTO) analyses or IP due diligence.
