Google's Chromebook, which isn't even in the stores yet, is already in trouble. ISYS, who owns the Xi3 Corporation, claims that the Chromebook name is too similar to its own ChromiumPC. ChromiumPC is a desktop PC that runs the Chrome OS. This isn't the first time the two companies fight over name infringement. Google filed a claim against ISYS, when it tried to trademark its ChromiumPC name last year. Google didn't like that and has therefore objected that the name had too much resemblance to its Chromium OS name. The claim means that a temporary restraining order is keeping Google from marketing its Chrome OS devices. There has yet to be a verdict, but I'll keep you posted.
