The holiday season brought an early gift for Mariah Carey as she successfully defended against a copyright infringement lawsuit that threatened one of the most beloved Christmas songs of all time. The case serves as an important reminder for practitioners about the stringent requirements for proving musical copyright infringement and the risks of pursuing weak claims.
The Christmas Carol Controversy
The legal dispute began when Andy Stone, performing under the stage name Vince Vance, and Troy Powers filed suit against Carey, her collaborator Walter Afanasieff and various music publishers. The plaintiffs claimed that Carey’s 1994 holiday phenomenon “All I Want for Christmas Is You” unlawfully appropriated elements from their own 1989 composition bearing the identical title. Their allegations encompassed a broad range of purported similarities including lyrics, compositional structure, chord progressions, melody and harmonic arrangements.
Carey’s version is a cultural touchstone, generating millions in royalties and streaming revenue each holiday season. The song’s commercial success and ubiquity make it a high-stakes target for copyright litigation.
Legal Framework and Strategic Positioning
Both parties acknowledged that the case would be resolved under the Ninth Circuit’s established extrinsic test for copyright infringement, which focuses on objective similarities between works rather than subjective audience impressions. This analytical framework required the court to examine whether any similarities between the songs constituted substantial similarity in protectable expression.
The court employed a bifurcated approach, separating the objective analysis from any potential jury consideration of subjective factors. This procedural decision proved favorable for the defendants, as it allowed for resolution through expert testimony and legal analysis rather than potentially unpredictable jury deliberations.

Expert witnesses played a crucial role in the proceedings, with both sides submitting detailed reports and depositions analyzing the musical compositions. The case ultimately turned on cross-motions for summary judgment, allowing the court to resolve the matter as a question of law rather than requiring a trial.
The Court’s Analysis and Reasoning
The court’s decision rested on fundamental principles of copyright protection in musical works. While granting summary judgment in favor of Carey and her co-defendants, the court emphasized that copyright law protects only original expression, not generic or commonplace elements that appear across multiple works.
The judicial analysis followed the Ninth Circuit’s three-step extrinsic test methodology. First, the court acknowledged the plaintiffs’ identification of various alleged similarities between the competing works. However, the critical second step involved filtering out similarities based on unprotectable material, including shared song titles, standard chord progressions and common musical phrases that form part of the public domain.
In the final analytical step, the court determined that any remaining similarities fell far short of the substantial similarity threshold required for copyright infringement. This finding effectively eliminated any genuine dispute of material fact, making summary judgment appropriate.
The court’s reasoning reflects well-established copyright doctrine that distinguishes between protectable original expression and the building blocks of creative works that remain available to all artists. Song titles, basic chord progressions and conventional musical phrases cannot form the basis for infringement claims because they represent the fundamental vocabulary of musical composition rather than protectable creative expression.
Sanctions and Deterrent Effect
Beyond the substantive victory, Carey and her legal team secured an additional win when the court granted their motion for sanctions against the plaintiffs. This award related specifically to the plaintiffs’ summary judgment filings and signals judicial disapproval of the litigation strategy employed.
The sanctions award serves multiple purposes within the broader litigation landscape. It provides compensation to the defendants for the costs associated with defending against what the court implicitly viewed as a meritless claim. More importantly, it sends a deterrent message to potential plaintiffs considering similar lawsuits based on weak factual or legal foundations.
Broader Implications for Music Copyright Practice
This decision reinforces several critical principles that intellectual property practitioners must consider when evaluating potential music copyright claims. The ruling demonstrates that shared titles alone cannot support infringement allegations, regardless of how distinctive or memorable those titles might be. Similarly, the use of common chord progressions, standard song structures or conventional lyrical themes will not satisfy the substantial similarity requirement.
The case also highlights the importance of expert testimony in music copyright litigation. The competing expert analyses provided the court with the technical foundation necessary to distinguish between protectable and unprotectable elements. Practitioners must carefully consider the strength of their expert evidence before pursuing or defending music copyright claims.
The willingness to award sanctions further emphasizes the need for thorough pre-litigation analysis. Courts have limited patience for copyright claims that fail to identify substantial similarities in protectable expression, particularly when the alleged similarities rest primarily on generic or commonplace elements.
Conclusion
Mariah Carey’s successful defense of her holiday classic reinforces the high evidentiary standards required for music copyright infringement claims. The case demonstrates that superficial similarities, shared titles and common musical elements cannot overcome the substantial similarity threshold established by federal copyright law.
For intellectual property practitioners, the decision serves as both a roadmap for analyzing music copyright claims and a cautionary tale about the risks of pursuing litigation based on unprotectable similarities. As the court’s reasoning makes clear, copyright protection extends only to original expression, not to the generic building blocks that form the foundation of musical composition.

In the end, all Mariah Carey wanted for Christmas was protection for her original creative work. The legal system delivered exactly that gift
