Research in Motion Ltd. (RIM) has sued Samsung Telecommunications America LLP, 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.
The US$450 BlackJack phone was introduced last month to the U.S. market, where it is sold exclusively by Cingular Wireless LLC.
Black Carbon is an ultra-thin phone sold directly by Samsung.
A Samsung spokesman declined to comment on the matter. "Samsung is not going to comment on pending litigation," he said.
