Tesla Motors can't seem to keep itself out of the press, can it? The newest flare-up concerns rival Fisker and claims that the automaker has stolen trade secrets and copied design concepts. In a lawsuit filed Monday by Tesla, the carmaker accuses Henrik Fisker -- whom the company had hired to design its WhiteStar sedan -- of accepting the work to "gain access to confidential design information and trade secrets." The company alleges that Fisker then used that knowledge to launch a competing vehicle, and believes Fisker has implemented its range-extended vehicle (or REV) technology in the recently introduced Karma. "I think it's ironic that Fisker chose to name his car the Karma, when what he's done is very bad karma," said the company's lawyer. Fisker wouldn't comment on the case, then drove silently away when pressed.
