The Globe and Mail reports in its Thursday edition that the parent company of the Toronto Maple Leafs is deciding whether it will formally oppose rapper Snoop Dogg's trademark for his marijuana company, Leafs by Snoop. The Globe's Alicja Siekierska writes that Calvin Broadus, the rapper known as Snoop Dogg, filed a trademark application for Leafs by Snoop with the U.S. Patent and Trademark Office on Nov. 17. According to the application, the trademark -- which is featured on Snoop Dogg's marijuana product line sold in Colorado -- includes the words Leafs by Snoop "presented on three lines and superimposed over a golden leaf design." NHL Enterprises filed a 90-day request for extension of time on behalf of Maple Leaf Sports and Entertainment to investigate Snoop Dogg's trademark registration. The extension request was granted on June 8. Snoop Dogg is also a pitchman for Canopy Growth. Eric Macramalla, a partner at Gowling WLG who focuses on trademark litigation, said parties generally seek an extension of time to try and settle a potential trademark dispute and avoid costly court proceedings. Mr. Macramalla says MLSE would likely rely on arguments about brand confusion and dilution.
