Tropes Aren’t Theft: What Freeman v. Wolff Teaches About Substantial Similarity in YA Fantasy Fiction

A recent decision from the Southern District of New York offers one of the most detailed modern analyses of substantial similarity in the increasingly popular young adult fantasy/“romantasy” space.

The case arose from a dispute between an unpublished author and the creator of a commercially successful paranormal romance series. The plaintiff alleged that her manuscripts—shared years earlier with a literary agent—were copied in the defendants’ novels. The court, however, granted summary judgment for the defendants, concluding that no reasonable jury could find substantial similarity of protectable expression.

The opinion is notable not just for its outcome, but for its methodical breakdown of what copyright law does not protect.

Why Lady Gaga Prevailed in the “Mayhem” Trademark Dispute 

The intersection of trademark law and the First Amendment remains one of the most complex battlegrounds in intellectual property. A recent ruling in the dispute between the surf and lifestyle brand Lost International and Lady Gaga provides a critical look at how courts are navigating trademark conflicts involving expressive works in a post-Jack Daniel’s landscape. 

In December, a federal court denied Lost International’s motion for a preliminary injunction, allowing Lady Gaga to continue using the mark “Mayhem” for her 2025 album, worldwide concert tour, and tour merchandise.

Who Really Owns Your Startup’s IP?

The Most Overlooked Mistake That Can Kill Your Company Before It Starts

Most founders assume their company owns what it builds. It doesn’t, at least not automatically.

Under U.S. law, the person who creates intellectual property owns it unless they’ve assigned it in writing. That means your company may not own its core code, designs, or brand even if you paid for them.

I’ve seen financings delayed, acquisitions fall apart, and founders lose control of their own products because they never secured clear IP ownership. It’s the single most common, and most avoidable, legal mistake in early-stage companies.

Unraveling the Statute of Limitations in Copyright Infringement Cases

In the realm of copyright law, determining the scope of damages and the applicability of the statute of limitations remains a contentious issue. The Supreme Court case of Nealy v. Warner Chappell Music (argued before the Court in February of this year) promises to shed light on this matter, grappling with the question of how far back a plaintiff can seek damages in a copyright infringement case. This pivotal legal battle has significant implications for copyright holders, defendants, and the broader creative industry landscape.

Authors Get Mixed Results With Initial Skirmish in OpenAI Lawsuit

OpenAI, Inc. develops artificial intelligence software involving large language models (“LLM”) known as ChatGPT.  In 2023, several authors, including the comedian Sarah Silverman, filed putative class action lawsuits alleging various copyright infringement claims. On February 12, 2024, a District Court in the Northern District of California issued its Order and ruled on the OpenAI defendants’ motions to dismiss various claims in the two pending putative class action lawsuits.

And Again, Abstract Ideas are Not Patentable!

The Federal Circuit Court of Appeals has struck down many patents on the grounds that they are invalid as directed to an abstract idea, relying on the Supreme Court’s Alice decision.  In In re Elbaum (Fed. Cir. 12/20/2023) 2023 U.S. App. LEXIS 33719, the Federal Circuit affirmed the Patent Trial and Appeal Board’s rejection of the claims in a patent application as directed to an abstract idea.

USPTO Issues Guidance on Patentability of Inventions Developed with the Assistance of Artificial Intelligence

On February 12, 2024, the United States Patent and Trademark Office (“USPTO”) issued guidance on the patentability of inventions developed with the assistance of artificial intelligence, saying that a human must have made a “significant contribution” to the invention. The USPTO explained that while AI-assisted inventions are not categorically unpatentable, the inventorship analysis should focus on human contributions, as patents function to incentivize and reward human ingenuity. Thus, patent protection may be sought for inventions for which a natural person provided a significant contribution to the invention, and the guidance provides procedures for determining the same.
