Maybe RIM has a point when they claim that people would get the Samsung Blackjack confused with the Blackberry, but it's a stretch. I'd also like to think that after all their problems with litigation in the past, RIM might be a little more forgiving than most companies. I suppose not.

Also in danger of getting sued: Black Keys, Black Mamba, and Black Panthers.

Research in Motion (RIM) has sued Samsung Telecommunications America, claiming that Samsung's BlackJack smart phone violates the BlackBerry trademark.
RIM is asking that Samsung be stopped from selling the BlackJack and Black Carbon mobile phones and is seeking unspecified damages, according to court filings. The lawsuit was filed Friday in the U.S. District Court for the Central District of California.
"Samsung is misleading the public into falsely believing that Samsung's goods and services are connected with RIM's business," the filing states.
