The world’s most popular English language song is now free from copyright after a federal judge ruled on Tuesday that filmmakers challenging Warner Chappel Music’s hold on “Happy Birthday to You” should be granted summary judgment.

According to the opinion on Tuesday from U.S. District Judge George H. King, “Because Summy Co. never acquired the rights to the Happy Birthday lyrics, Defendants, as Summy Co.’s purported successors-in-interest, do not own a valid copyright in the Happy Birthday lyrics.”
