The author analyzed a song heard in a store, which shared the same melody as an original track but featured a different arrangement and key. Using chroma-based analysis, the study confirmed the track was a re-recording rather than a direct copy. This highlights a long-standing legal distinction: copyright protects specific expressions, not underlying ideas or concepts.
In the music industry, legal precedents like the 'Blurred Lines' case (2015) resulted in a $5,3 million judgment and 50% of future royalties, while the 'Dark Horse' case (2019) saw a $2,8 million verdict overturned on appeal. These cases demonstrate that while direct copying is prohibited, the line between protected expression and common musical building blocks remains subject to judicial debate.
The software industry established the 'clean room' design process in the 1980s to avoid copyright infringement, as seen in the IBM PC BIOS cases. More recently, the 2021 Oracle v. Google ruling established that using 11 500 lines of Java API code could constitute fair use, though the court did not declare APIs inherently uncopyrightable.
AI has significantly lowered the cost of 're-assembling' content. In June 2024, major labels including Universal, Sony, and Warner sued AI music generators Suno and Udio, presenting side-by-side transcriptions as evidence. By 2026, many labels, including Universal and Warner, opted for licensing deals over litigation, though Sony continues its legal challenge regarding 333 works.
For creators, the author suggests that copyright remains effective against direct copying but offers limited protection against re-assembly. Strategies for protection include shifting value toward non-reproducible assets like exclusive data, trade secrets, brand identity, and community engagement, rather than relying solely on copyright for creative expressions.
