A small Ontario hockey supplier is taking on industry giant Reebok-CCM Hockey Inc. in a gloves-off brawl over a popular new stand-up style of wheeled hockey gear bag.

Grit Inc., based in Tottenham, Ont., has filed a case in Federal Court alleging Reebok subsidiary Sport Maska Inc. has started marketing a new hockey bag that is similar to Gritís well-known Hockey Tower. Grit alleges the design infringes on its registered industrial design and patent.
