The English rock band, worth more than half a billion pound, is taking legal action against New Yorker Fashion and demanding a 210,000 pounds settlement and a 17,000 pounds fine for using their iconic image of a mouth on a sale poster, reported Sun online.
A spokesman for the band said, "As with any band or major brand, we will be fiercely protective of our commercial properties, be that songs, gigs or logos.
"If we didn't chase up improper use it would set a dangerous precedent."
"The tongue is not the Stones' alone. The posters were made by our creative department. I won't let the Stones ban my tongue," Knapp said.
Knapp has been forced to remove a number of posters from 800 stores and pull out more than 3,000 clothes tags with the tongue on it, but the court case still looms over him.
