NEW YORK — A production company making a documentary about the song “Happy Birthday to You” is challenging the copyright to the famous jingle.

Good Morning To You Productions Corp., which is working on a film tentatively titled “Happy Birthday,” argues in a lawsuit filed Thursday that the song should be “dedicated to public use and in the public domain.” The company is seeking monetary damages and restitution of more than $5 million in licensing fees collected by Warner/Chappell Music Inc. from thousands of people and groups who’ve paid it licensing fees.

“More than 120 years after the melody to which the simple lyrics of ‘Happy Birthday to You’ is set was first published, defendant Warner/Chappell boldly, but wrongfully and unlawfully, insists that it owns the copyright to ‘Happy Birthday to You,’ ” the lawsuit states.

Warner/Chappell, based in Los Angeles, claims exclusive copyright to “Happy Birthday to You,” which Guinness World Records has called the most famous song in the English language.

The company, whose artists have included Aretha Franklin, Barry Gibb, Rob Zombie, Madonna and Michael Jackson, didn’t immediately respond to a request for comment Thursday.

Good Morning To You Productions argues that evidence dating to 1893 helps show the song’s copyright expired around 1921. It says four previous copyrights to the melody of the similar-sounding song “Good Morning to All,” filed in 1893, 1896, 1899 and 1907, have expired or been forfeited.
