The media is treating the TTAB’s cancellation of 6 of the Redskins’ trademarks as if this is the end of the name/mark (pending appeal).
But, as the TTAB itself points out, federal registration is not the totality of trademark protection. Should the Redskins desire to continue using the marks/name–even if they appeal the TTAB decision and lose–they can enforce under state registration and/or common law rights. This is certainly more onerous than having nationwide federal rights. And it runs the risk that there might be some senior users in particular jurisdictions. But there are plenty of state-based marks used as brands out there. A good sign is whether the mark is identified by “™” or “SM” rather than ®. The latter may only be used for federally registered marks.
Thus, whether one likes the name or not, nothing about this TTAB decision itself forces Dan Snyder and the Redskins to abandon the mark/brand.
