Is use of a registered trademark compulsory in Poland?
It is not compulsory. However, the right of protection for a trademark may be declared lapsed in case of no genuine use of the registered trademark for the goods covered by the registration within five consequtive years, unless serious reasons of non-use thereof are provided. The Patent Office may render a decision on the lapse of the right of protection for a trademark at request of any party having legitimate interest therein.
