LOS ANGELES (AP) — “Happy Birthday To You” no longer has a valid copyright. That’s the ruling from a federal judge. U.S. District Judge George H. King ruled yesterday that the copyright originally filed by the Clayton F. Summy Co. in 1935 granted only the rights to specific arrangements of the tune and not the actual song itself. Warner/Chappell Music has been enforcing the copyright claim since it bought Summy’s successor, the Birch Tree Group. Warner/Chappell has said it doesn’t try to collect royalties from just anyone singing the song but those who use it commercially.
