[JURIST] A US District Judge in Connecticut has ruled that Gillette's claims that its multi-blade M3Power razor [corporate product profile] lifts hair for a closer shave are "unsubstantiated and inaccurate," granting competitor Schick [company website] a preliminary injunction prohibiting television or print ads of the razor. A Gillette [corporate website] spokesperson said that the company has not decided whether to appeal the decision. The two companies have battled in court before, including a protracted patent fight in which Gillette claimed Schick violated its multi-blade patent. AP has more.
