Tupac Shakur's defiant mother has fired back at claims she stole a designer's branded logo, and now she's attempting to strip him of his trademark. Last month, clothing designer Isaiah Israel accused Shakur of using his Marco Bellini clothing line logo, which he created in 1998, to inspire the design for her Makaveli Branded logo, which she launched in 2004.

Israel is seeking damages of $500,000.

Shakur contends that no trademark infringement has taken place, and she plans to cancel Israel's mark after gathering her legal fees from him.

Her lawyer Donald N. David says, "There is no basis for Mr. Israel's suit and an appropriate answer has been filed in the action that he has commenced denying all of his baseless allegations. In addition, an action has been commenced to cancel Mr. Israel's mark in that he has failed in use such mark in interstate commerce as required."
