Research In Motion Ltd.’s use of the BBM moniker for its popular BlackBerry Messenger service does not infringe BBM Canada’s trademark on the three-letter name, a Federal Court ruled Wednesday. In its decision, the court said RIM’s use of the phrase did not infringe BBM Canada’s 68-year-old trademark because the two companies operate in different sectors. It said this left little room for confusion between BBM Canada and the BlackBerry instant messaging application. Jim MacLeod, president and CEO of BBM Canada, said the broadcast measurement company will consider whether to appeal the decision. "These things are skirmishes in the war, so I don't know if this is over or not," MacLeod told the Canadian Press on Thursday.
