As from January 1 2004 essential changes will be introduced in the Polish structure of jurisdiction and two Acts will come into force - the Act on the Structure of Common Courts of Law and the Act on Administrative Procedure. Administrative jurisdiction will be a two-tiered one. Up to now the only court in control of administrative issues has been the Supreme Administrative Court. As from next year there will also be regional administrative courts. The necessity to introduce two-tiered administrative jurisdiction derives from the provisions of the new Constitution of the Republic of Poland adopted in 1997. These legal changes will exert substantial influence on issues related to industrial property protection in Poland, including trade marks. Along with these Acts entering into force, the Law on Industrial Property that applies, among others, to trade mark protection will also change.
