Representative Legal Matters

  • Successfully represented one of Poland's biggest producers of confectionery regarding their most renowned brand, which helped the client to create and implement a strategy which led to reacquiring the distinctiveness of their degenerated trademark after a 10-year legal battle consisting of a series of litigation proceedings.
  • Represented a multinational pharmaceutical company in a major patent litigation case over an insulin pen. This litigation case involved the issue of enforcing European patents under Polish law, and in particular the interpretation of patent claims written from a functional perspective.
  • Advising an American multinational conglomerate corporation operating in the fields of industry, worker safety, health care, and consumer goods in domain name arbitration cases, trade mark infringement cases, anti-counterfeiting cases, patent filings and IP commercial.
  • Represented a European sports association in connection with intellectual property issues such as litigation against a Polish tour operator for unfair competition and trade mark infringement.
  • Advising a social media company with respect to the alleged infringement of third party trademark rights by our client’s communities. These matters have a significant influence on the client’s policy with respect to take-down notices reported from Polish entities and with respect to content available to Polish social media users.
  • Advised an American multinational technology company with respect to a number of proceedings that target fake online stores. These stores misrepresent themselves as our client’s authorized resellers, often sell fake products and use the client's trademarks on their websites and domain names containing the client's trademarks.
