Canadian based Research in Motion is suing Samsung over its use of the mark BlackJack in association with a recently launched smart phone device. The Samsung smart phone competes directly with RIM’s BlackBerry Pearl smart phone. In the lawsuit, filed in California, RIM argues that the BlackJack name will cause confusion with consumers who are familiar with the established BlackBerry brand, as well as constituting false designation of origin, unfair competition and trademark dilution.  Interestingly, both devices are offered on Cingular’s network in the U.S.
