Praised for its ability to combine ‘legal excellence with a rare level of engagement and accessibility’, Kochanski & Partners continues to attract a steady stream of work from the pharmaceutical, media and FMCG spaces, thanks to its strong track record in defending trade marks and patents, particularly in infringement and advertising disputes. The practice is jointly steered by Piotr Kochanski, who focuses on IP transfers, financing and protection, and Karolina Marciniszyn, whose core strengths lie in litigation before the common courts and the PPO. Tomasz Szambelan has extensive experience in handling intellectual property infringements in the pharmaceutical, food and new technology industries.
