The amendment of the Norwegian Customs Act section 39, which was implemented as of September 1 2007, makes it possible for the Customs authorities to notify owners of IP rights if there is probable and reasonable cause to believe that the imported goods are infringing the IP rights. Customs may with this amendment ex officio retain suspected goods for five days and thus give an IP owner the possibility to take action. Before this amendment, it was necessary to obtain an interlocutory injunction from a court in order to enable the Customs to retain suspect goods. The amendment creates a new and better instrument in the battle to fight piracy and counterfeits, making it easier to enforce IP rights. The Norwegian Patent Office will assist the Customs to identify the IP owners, enabling them to notify correctly.
