Toronto Maple Leafs Sports and Entertainment have filed an opposition to the logo by Snoop Dogg's marijuana products business "Leafs by Snoop", according to TSN's Rick Westhead.

The opposition was filed on June 8 while Snoop's products - including eight strains of marijuana - have been sold in various Colorado pot shops since November, around the time Snoop filed his trademark application for Leafs by Snoop.

Christopher Sprigman - an intellectual properties professor at the New York University School of Law - suggested to Westhead that MLSE might argue Snoop's logo could cause confusion in the marketplace or that it meets the requirement of fame, but he feels both cases would be difficult to prove.

In the meantime MLSE's legal representation has asked for more time to detail its opposition, where a clear reason for the counter should then arise.
