A federal judge threw out what was described as an absurd copyright infringement lawsuit against Taylor Swift on Monday, delivering a sweeping legal victory to the pop star and drawing a firm line around what the law does — and does not — protect.
U.S. District Judge Aileen Cannon granted a motion to dismiss a case brought by Kimberly Marasco, a self-published poet from Florida who claimed Swift had lifted material from her poems and embedded it throughout more than a dozen songs. The lawsuit was dismissed with prejudice, meaning Marasco cannot refile the claims.
Court documents show Marasco alleged that Swift drew from her work for songs spanning five albums: “Lover,” “Folklore,” “Evermore,” “Midnights” and “The Tortured Poets Department.” Cannon determined that whatever the two works shared — concepts like gaslighting, sweeping romantic metaphors, observations about human experience — belonged to the category of ideas and common expression that copyright law has never been designed to cover.
What the Judge Actually Found
Cannon’s ruling was pointed in its reasoning. She determined that whatever the two works shared — concepts like gaslighting, sweeping romantic metaphors, observations about human experience — belonged to the category of ideas and common expression that copyright law has never been designed to cover. The law protects original creative expression in a specific, fixed form, not the territory of broad themes or everyday language that any writer might reach for.
Cannon wrote that “the allegedly infringed material — basic ideas, themes, metaphors, isolated words, and short phrases — is not protected expression and cannot be infringed.” The judge also noted that the shared elements amounted to “quintessential themes, concepts, and isolated words — exactly the kind of material copyright law does not protect.”
The ruling underscored a foundational principle of intellectual property law: that protecting ideas themselves, rather than the unique expression of those ideas, would effectively allow creators to monopolize the building blocks of human storytelling. A poet cannot claim ownership of the concept of heartbreak any more than a painter can copyright the color blue.
A Pattern of Failed Claims
Monday’s dismissal was not Marasco’s first courtroom defeat in her pursuit of Swift. She had previously filed separate lawsuits against the singer, each of which was also thrown out before reaching trial. That history weighed heavily in Cannon’s decision to bar Marasco from amending and refiling her complaint yet again.
The court had already given Marasco an explicit warning: the Second Amended Complaint she submitted would be her final opportunity to make her case. She did not clear the bar. Judge Cannon said Marasco had ample opportunity to plead her claims and had been expressly warned that no further chances would follow.
Dismissal with prejudice is among the more definitive outcomes a civil defendant can receive. It closes the door on refiling the same claims in federal court and signals that, from a judge’s perspective, no revision to the complaint could salvage a legally viable case.
Copyright Law and the Limits of Protection
The Swift case is a clear illustration of where copyright protection ends. Under established U.S. copyright doctrine, protection attaches to original expression — the specific arrangement of words, the particular structure of a sentence, the distinctive way an idea is rendered on the page. It does not extend to the idea itself, to short phrases, to common metaphors, or to themes so universal they appear across centuries of literature.
Courts have repeatedly confronted cases in which plaintiffs attempt to stretch copyright claims beyond that boundary, often by arguing that two works explore similar emotional or conceptual terrain. In nearly every instance, judges have drawn the same distinction Cannon drew here: similarity of subject matter is not similarity of protectable expression.
For Swift, the ruling adds to a record of successfully defending against copyright challenges tied to her catalog. Her albums, particularly the more recent ones that Marasco cited, have attracted intense public and critical attention, and with that attention has come litigation from parties claiming creative ownership over words, phrases and ideas the songs contain.
What Comes Next
With the case dismissed with prejudice, Marasco has no path to refile her claims in federal court under the same legal theory. Whether she pursues any other avenue remains to be seen, though the judge’s ruling — and the history of prior dismissals — leaves little room for a different outcome on the same set of allegations.
For the music industry more broadly, the outcome reinforces what courts have long maintained: that songwriters, like all authors, are entitled to write about love, loss, betrayal and the full spectrum of human emotion without those themes becoming the exclusive property of any one creator. The ruling drew the line with precision — and with finality.
