Norelco has succeeded in obtaining a TRO regarding advertising for the Remington shaver, on false advertising grounds. The decision was in the Southern District of NY on Friday. News coverage is somewhat sketchy but the suit centers around claims in the commercial that the shaver uses titanium, a metal, when in fact it contains titanium nitride, a ceramic.
