IIn today’s Rzeczpospolita, Dr. Michal Markiewicz writes about trademarks. It is worth remembering that in addition to the prerequisites for individual forms of infringement, an encroachment on the protective right must consist of a violation of general prerequisites, including the key ones from the perspective of determining the scope of the right itself, use of the sign in business dealings, use in relation to goods and services, violation of the function of the trademark, and illegality. So what is the use of a sign as a trademark? And how to understand the necessity of infringing the function of a trademark? The evolution of case law on the one hand makes this branch of law more flexible, but on the other hand introduces significant uncertainty about the very scope of the law.
