King ruled that Warner/Chappell’s claim to the “Happy Birthday” lyrics were simply not supported by the facts. The Hill sisters “did not try to obtain federal copyright protection” and so could not pass those rights on to another company, and eventually to Warner, King wrote. And when a copyright was registered in 1935, it was for a particular piano melody, not the lyrics, King pointed out. Besides, by then “Happy Birthday” was already solidly in the public domain.Breaking Warner's stolen monopoly is good, but not the important part.
