The Happy Birthday Copyright Case: Lessons in Chain of Title and Public Domain Music

“Happy Birthday to You” is one of the most recognisable melodies in the world — and for nearly a century, also one of the most expensive. Warner/Chappell Music and its affiliate Summy-Birchard collected millions of dollars in licensing fees from filmmakers, advertisers, and broadcasters using the song, based on a 1935 copyright registration. The claim collapsed in 2015 when a US federal court ruled that the registration did not actually cover the lyrics. The resulting $14 million settlement and the case’s lessons on chain of title verification and public domain assessment remain operationally significant for music clearance across all jurisdictions.

The Warner/Chappell claim

Warner/Chappell based its Happy Birthday copyright on a 1935 registration (E51990), asserting control over the song’s lyrics. Importantly, copyright in lyrics and music can exist independently — and the melody itself had already entered the US public domain in 1949. Warner/Chappell therefore focused exclusively on the words.

The historical claim traced back to sisters Mildred and Patty Hill, who in 1893 published a song called Good Morning to You using the same melody. Warner/Chappell argued that Patty Hill subsequently wrote the Happy Birthday lyrics and assigned all rights to the predecessor company Clayton F. Summy in the 1930s — providing the documentary basis for ongoing royalty collection through Warner/Chappell.

For decades, this chain of attribution went unchallenged. Filmmakers, advertisers, and television producers routinely paid substantial licence fees rather than risk litigation. One plaintiff in the eventual class action had been asked to pay $1,500 to include the song in a single documentary.

The class action and the 2015 ruling

In 2013, several production companies filed Good Morning to You Productions Corp. et al. v. Warner/Chappell Music, Inc. in the US District Court for the Central District of California, challenging the copyright claim on chain-of-title grounds.

After two years of proceedings, Judge George King issued his ruling on 22 September 2015. The decision found:

• The 1935 registration (E51990) covered only a specific piano arrangement, not the underlying lyrics;
• No credible evidence existed that the Hill sisters had ever transferred copyright in the lyrics to the Summy Company;
• Warner/Chappell’s chain of title was therefore broken at its foundation;
• The company did not own the Happy Birthday lyrics — the song was effectively in the public domain.

The decision overturned nearly 80 years of assumption. Copyright registration alone, the court emphasised, does not establish ownership — the underlying transfer chain must be documented and verifiable.

The $14 million settlement

Rather than face trial on damages and a potential class certification expanding liability back decades, Warner/Chappell settled in early 2016 for $14 million. The settlement included refunds of licence fees paid by class members dating back to 1949 (the year the melody entered the US public domain). The settlement effectively confirmed what copyright scholars had long argued: “Happy Birthday to You” belongs to the public.

The chain of title lesson

The case is a landmark teaching moment for entertainment IP lawyers. Key lessons:

• Registration ≠ ownership: copyright registration is evidentiary, not constitutive. Without underlying chain of title documentation, registration does not establish enforceable rights;
• Historical assumptions can be wrong: even long-standing royalty collection patterns may rest on flawed foundations;
• Burden of proof: in copyright litigation, the claimant must prove the chain of title with credible evidence — not merely cite registration;
• Lyrics vs music separately: copyright in lyrics and music exists independently, with separate ownership chains;
• Public domain analysis: requires careful verification of when each element of a work entered the public domain in each jurisdiction.

Italian and EU framework

The same lessons apply under Italian and EU law:

• Article 110 LDA: rights transfer requires written form. Without proper documentation, asserted rights may be unenforceable;
• Articles 25-26 LDA: copyright duration in Italy is 70 years post mortem auctoris (after the death of the author);
• EU harmonisation: Directive 2006/116/EC and Directive 2011/77/EU establish unified 70-year framework across the EU;
• L. 182/2025: extended photographic protections to 70 years from creation (Italian-specific reform);
• SIAE registration: Italian copyright registration with SIAE is evidentiary but not constitutive — the underlying authorship chain must still be verifiable.

For Italian music producers, broadcasters, and content creators, chain of title verification is essential before incurring license fees or risking infringement claims.
