 Shortly after the announcement, the CBC filed applications to protect what appear to be three versions of "The Hockey Theme" as sound trademarks.These applications were abandoned on December 30, 2009.Even if the trademark applications had been successful, the most favourable result for the CBC would have been that it could prevent CTV from using the theme during hockey broadcasts; the CBC itself would likely still have been barred from using the theme due to CTV's status as copyright holder.
