Army challenge

The US Army has filed a challenge opposing the application of the NHL’s newest franchise to register the trademark ‘‘Las Vegas Golden Knights’’. In a claim with the US Trademark Trial and Appeal Board in suburban Washington, the Army claims it will be damaged by registration of the marque and says it has acquired exclusive rights that predate any rights claimed by the NHL team. The Army says it has used the Golden Knights nickname since the late 1960s for its parachute team, public relations and recruiting, and claims it owns ‘‘common law rights’’ for the colour schemes that combine black and gold and yellow and white.
