Abstract
The purpose of the article is to present the problem of the trademark protection in Polish law. This protection takes place in a civil law proceedings. It may be impeded if the defendant begins to challenge the validity of the trademark. The court cannot decide on the validity of the trademark; the decision on the invalidation of the trademark may be taken only by the Patent Office. For this reason, the court should suspend the civil law proceedings which can last a very long time. Therefore, in Polish law, following the example of EU law, consideration should be given to the possibility of determining the validity of the trademark also by a court, if such a need occurs during the civil law proceedings.
