For several years, he has acted as co-counsel for one of the largest pharmaceutical companies in the world, handling multi-jurisdictional patent litigation while defending valuable patents covering various active substances against generic competitors. Peter also acted as co-counsel in proceedings before the European Patent Office and the Belgian courts for a major medical devices company in patent litigation which covered three jurisdictions.
