The singer and frontman for the band Kiss says he first made the sign in November 1974 while performing on stage.
However he may struggle to get the trademark passed because it also means "I love you" in American Sign Language.
Other rockers including Ronnie James Dio have also been credited with introducing the sign to rock music.
In the trademark application, the sign is described as consisting "of a hand gesture with the index and small fingers extended upward and the thumb extended perpendicular."
