Gene Simmons, the guy from KISS with the long tongue, has filed an application with the US Patent and Trademark Office claiming that he created the devil’s horn hand gesture. Simmons is claiming that he first used the gesture whilst KISS were performing following the release of their second album Hotter Than Hell in 1974.
The application is seeking to trademark the hand gesture when it is used for “entertainment, namely, live performances by a musical artist; personal appearances by a musical artist", and features a drawing of his version of the devil's horns, which features the use of a thumb.
The hand signal has been used throughout the world for decades, and is also the symbol for 'I love you' in American sign language, which may have been the intended meaning when John Lennon made the gesture on the cover of The Beatles' 'Yellow Submarine' single.
Ronnie James Dio also had some opinions about the history of the gesture...
