2023 was a big year for U.S. intellectual property law. Major developments occurred in every area. Here are the highlights.

Copyright

Fair Use

Andy Warhol Foundation for the Visual Arts v. Goldsmith

This was one of the top copyright cases of 2022. It was a case that was pushing the limits of the  transformative fair use of photographs. The Supreme Court issued a ruling in the case in May. The decision is significant because it finally reined in the “transformative use” doctrine that the Court first announced in Campbell v. Acuff-Rose Music back in 1994. In that case, 2 Live Crew had copied key parts of the Roy Orbison song, “Oh, Pretty Women” to make a parody of the song in its own rap style. The Court held that the 2 Live Crew version, although reproducing portions of both the original song and the original recording of it without permission, transformed it into something else. Therefore, even though it infringed the copyright, the 2 Live Crew version was for a transformative purpose and therefore protected as fair use.

In the thirty years since Campbell, lower courts have been applying the “transformative use” principle announced in Campbell in diverse and divergent ways. Some interpretations severely eviscerated the copyright owner’s exclusive right to make derivative works. Their interpretations often conflicted. What one circuit called transformative “fair use” another circuit called actionable infringement. Hence the need for Supreme Court intervention.

In 1984, Vanity Fair licensed one of photographer Lynn Goldsmith’s photographs of Prince to illustrate a magazine article about him. Per the agreement, Andy Warhol made a silkscreen using the photograph for the magazine and Vanity Fair credited the original photograph to Goldsmith. Unknown to her, however, Warhol proceeded to make 15 additional works based on Goldsmith’s photograph withour her permission.. In 2016, the Andy Warhol Foundation for the Arts licensed one of them to Condé Nast as an illustration for one of their magazines. The Foundation received a cool $10,000 for it, with neither payment nor credit given to Goldsmith. The Foundation then filed a lawsuit seeking a declaration that its use of the photograph was a protected fair use under 17 U.S.C. § 107. The district court granted declaratory judgment in favor of the Foundation. The Second Circuit Court of Appeals reversed, ruling that the four-factor “fair use” analysis favored Goldsmith. The Supreme Court sided with the Court of Appeals.

Noting that it was not ruling on whether Warhol’s making of works using the photograph was fair use, the Court limited its analysis to the narrow question whether the Foundation’s licensing of the Warhol work to Condé Nast was fair use. On that point, the Court determined that the use of the photograph to illustrate a story about Prince was identical to the use Goldsmith had made of the photograph (i.e., to illustrate a magazine article about Prince.) Unlike 2 Live Crew’s use of “Oh, Pretty Woman,” the purpose of the use in this case was not to mock or parody the original work.

The case is significant for vindicating the Copyright Act’s promise to copyright owners of an exclusive right to make derivative works. While Warhol put his own artistic spin on the photograph – and that might have been sufficient to sustain a fair use defense if he had been the one being sued – the Warhol Foundation’s and Condé Nast’s purpose was no different from Goldsmith’s, i.e., as an illustration for an article about Prince. Differences in the purpose or character of a use, the Court held, “must be evaluated in the context of the specific use at issue.” Had the Warhol Foundation been sued for displaying Warhol’s modifications of the photograph for purposes of social commentary in its own gallery, the result might have been different.

Although the holding is a seemingly narrow one, the Court did take the opportunity to disapprove the lower court practice of ending a fair use inquiry at the moment an infringer asserted that an unauthorized copy or derivative work was created for a purpose different from the original author’s.

Statute of Limitations and Damages

Warner Chappell Music v. Nealy

The U.S. Supreme Court granted certiorari to review this Eleventh Circuit decision. At issue was whether a copyright plaintiff may recover damages for infringement that occurred outside of the limitations period, that is, infringement occurring more than three years before a lawsuit was filed.

The circuits were split on this question. According to the Second Circuit, damages are recoverable only for acts of infringement that occurred during the 3-year period preceding the filing of the complaint. The Ninth and Eleventh Circuits, on the other hand, had held that as long as the lawsuit is timely filed, damages may be awarded for infringement that occurred more than three years prior to the filing, at least when the discovery rule has been invoked to allow a later filing. In Nealy, the Eleventh Circuit held that damages may be recovered for infringement occurring more than three years before the claim is filed if the plaintiff did not discover the infringement until some time after it first began.

The United States Supreme Court has resolved the Circuit split. Read about the Supreme Court’s decision in Warner Chappell Music, Inc. v. Nealy.

Artificial Intelligence

Copyrightability

Thaler v. Perlmutter

This was an APA proceeding initiated in the federal district court of the District of Columbia for review of the United State Copyright Office’s refusal to register a copyright in an AI-generated work. In August, 2023, the district court upheld the Copyright Office’s decision that an AI-generated work is not protected by copyright, asserting that “human creativity is the sine qua non at the core of copyrightability….” For purposes of the Copyright Act, only human beings can be “authors.” Machines, non-human animals, spirits and natural forces do not get copyright protection for their creations.

Thaler appealed. Read more about what happened in Last Exit from Paradise.

Infringement

Many cases that are pending allege that using copyrighted works to train AI, or creating derivative works using AI, infringes the copyrights in the works so used. Most of these cases make additional claims as well, such as claims of unfair competition, trademark infringement, or violations of publicity and DMCA rights.

 I have been blogging about these cases for some time and periodically provide updates on them.

Trademark

Parody Goods

Jack Daniel’s Properties v. VIP Products

For more information about this case, read Balancing the First Amendment on Whiskey and Dog Toys.

This is the “parody goods” case. VIP Products used the “Bad Spaniels” name to market its dog toys, which were patterned on the distinctive shape of a Jack Daniel’s whiskey bottle. VIP filed a lawsuit seeking a declaratory judgment that its product did not infringe the Jack Daniel’s brand. Jack Daniel’s counterclaimed for trademark infringement and dilution. Regarding infringement, VIP claimed First Amendment protection. Regarding dilution, VIP claimed the use was a parody of a famous mark and therefore qualified for protection as trademark fair use. The district court granted summary judgment to VIP.

The Supreme Court reversed. The Court held that when an alleged infringer uses the trademark of another (or something confusingly similar to it) as a designation of source for the infringer’s own goods, it is a commercial, not an expressive, use. Accordingly, the First Amendment is not a consideration in such cases.

Rogers v. Grimaldi had held that when the title of a creative work (in that case, a film) makes reference to a trademark for an artistic or expressive purposes (in that case, Fred Astaire and Ginger Rogers), the First Amendment shields the creator from trademark liability. In the Jack Daniel’s case, the Court distinguished Rogers, holding that it does not insulate the use of trademarks as trademarks (i.e. as indicators of the source or origin of a product or service) from ordinary trademark scrutiny. Even though the dog toys may have had an expressive purpose, VIP admitted it used Bad Spaniels as a source identifier. Therefore, the First Amendment does not apply.

The Court held that the same rule applies to dilution claims. The First Amendment does not shield parody goods from a dilution claim when the alleged diluter uses a mark (or something confusingly similar to it) as a designation of source for its own products or services.

International Law

Abitron Austria v. Hetronic International

Here, the Supreme Court held that the Lanham Act does not have extraterritorial reach. Specifically, the Court held that Sections 1114(1)(a) and 1125 (a)(1) extend only to those claims where the infringing use in commerce occurs in the United States. They do not extend to infringement occurring solely outside of the United States, even if consumer confusion occurs in the United States.

The decision is a reminder to trademark owners that if they want to protect their trademark rights in other countries, they should take steps to protect their rights in those countries, such as by registering their trademarks there.

Patents

Patents are beyond the scope of this blog. Even so, a couple of developments are worth noting.

Enablement

Amgen v. Sonofi

In this case, the Supreme Court considered the validity of certain patents on antibodies used to lower cholesterol under the Patent Act’s enablement requirement (35 U.S.C. sec. 112(a)).  At issue was whether Amgen could patent an entire genus of antibodies without disclosing sufficient information to enable a person skilled in the art to create the potentially millions of antibodies in it. The Court basically said no.

If a patent claims an entire class of processes, machines, manufactures, or compositions of matter, the patent’s specification must enable a person skilled in the art to make and use the entire class. In other words, the specification must enable the full scope of the invention as defined by its claims.

Amgen v. Sanofi, 598 U.S. ____ (2023)

Conclusion

My vote for the most the significant IP decision in recent times is Andy Warhol Foundation v. Goldsmith. Lower courts had all but allowed the transformative use defense to swallow up the exclusive right of a copyright owner to create derivative works. The Supreme Court provided much-needed correction. I predict that going forward, the most significant decisions will also be in the copyright realm, but they will have to do with AI.

Enduring (Non-AI) Legal Issues

With so much attention being given to the legal issues that AI-powered technologies are generating, it can be easy to overlook or underestimate the importance of long-standing legal issues having nothing to do with artificial intelligence. While it would be neither possible nor particularly useful to catalog all of them in a single blog post, it might be helpful to highlight a few key legal issues that are developing alongside developments in AI law.

Copyright Law

The core principles of intellectual property remain anchored in traditional law. In that connection, it is important to understand the philosophy of copyright. Copyright is not the only kind of intellectual property there is, but it is by far the most common. Everyone who has ever written a story or a poem, scribbled a doodle, or composed an email message is very likely a copyright owner. Merit is not a requirement. In theory, even that terrible drawing of a turkey you made in first grade by tracing your fingers and hand on paper and drawing a head and two legs on it may be protected by copyright. Whether it makes sense to pay the filing fee to register something like that is a different story.

A key issue in copyright law that continues to evolve is fair use. Courts have been grappling with how to interpret and apply the four vaguely worded factors they must to make findings about whether a particular otherwise-infringing use is “fair” or not. The idea of “transformative use” is at the center of this evolving doctrine. Andy Warhol Foundation for the Visual Arts v. Goldsmith, decided in 2023, is a leading case in this area now. Other limitations on copyright infringement liability, such as the safe harbors set out in the Digital Millennium Copyright Act (DMCA), are also important. There are also evolving protections for sound recordings and licensing. Other topics in copyright law include such things as the copyright registration requirement, damages for copyright infringement, diversity, copyright estoppel, the limitations period for copyright infringement, the extent of protection for shorter works, compulsory e-book licensing, and circumvention of copyright protection measures. 

The Internet Archive lawsuit addressed the phenomenon of digitized e-books and the impact on authors of making them freely available to readers via an online digital library. 

The new administrative court for resolving smaller copyright claims, the Copyright Claims Board, is one of the more significant developments in copyright law in a long time. Find out what to know about the new CCB.

Trademark Law

There has been a surge in interest in trademark law ever since the COVID-19 phenomenon. Many small brick-and-mortar businesses had to shut down as people were instructed to quarantine at home. While quarantining at home, a lot of people had the same idea: Starting a home-based, online business. Those new online businesses needed to have names. The USPTO was soon flooded with an unusually large number of trademark registration applications. Competition in the trademark space became fierce. Descriptiveness and likelihood-of-confusion challenges increased. New laws and procedures, such as the Trademark Modernization Act, were enacted to clear more room for new businesses by cancelling unused trademarks and cancelling registrations for classes of goods and services no longer being used by the trademark owners. Interest in nontraditional marks like color marks, trade dress, and sound and olfactory trademarks (smell marks) has also grown.

The clash between First Amendment values and trademark interests continues to surface from time to time. Courts have addressed trademark speech rights on several occasions now. 

And of course, distinctiveness, likelihood of confusion, and registration disputes are ongoing. 

Other Legal Topics

Constitutional law acquired renewed relevance in 2025, with issues running the gamut from freedom of speech to the separation of powers.

Dramatic changes in family structures and sex roles have been accompanied by major changes in family law, particularly in regard to the custody of children. More jurisdictions are warming up to the ideas of joint custody and shared parenting.

E-commerce law, too, is rapidly evolving, as more and more businesses supplement their physical presence with an online one. A growing number of businesses operate exclusively online. This has raised a wide range of legal issues entailing significant permutations of existing laws, and in some cases, brand new laws and legal frameworks.

As I mentioned at the outset, it would be neither possible nor useful for me to catalog every new legal development in a blog like this. The best I can do is highlight a few of them from time to time.

In this category is a post I wrote about a continuing legal education program I presented with Donald Hubin (National Parents Organization) and Professor Daniel Fernandez-Kranz:

Joint Custody and Equal Shared Parenting Laws

Pertinent to e-commerce law is an article I wrote about the sales and use tax “nexus” requirement for taxes on online sales:

Foundational Context: Major IP Developments of 2023

This section is a repost of an article I wrote in 2023 describing major developments in various areas of intellectual property law that took place that year. While I have broadened the scope of the discussion, it can still be useful to look back at what went on during that pivotal year, as it provides important context for the developments in IP law that are taking place now.

Copyright: Fair Use

Andy Warhol Foundation for the Visual Arts, Inc. v. Goldsmith et al.

I’ve written about this case before as one of the top copyright cases of 2022 and as an aspect of photographers’ rights. The United States Supreme Court issued a ruling in the case in May. The decision is significant because it finally reined in the “transformative use” doctrine that the Court first announced in Campbell v. Acuff-Rose Music back in 1994.

Most of these cases make additional claims as well, such as claims of unfair competition, trademark infringement, or violations of publicity and DMCA rights.

I have been blogging about these cases throughout the year. Significant rulings on the issues raised in them are expected to be made in 2024.

Trademark: Parody Goods

Jack Daniels’s Properties Inc. v. VIP Products LLC

For more information about this case, read my article, Balancing the First Amendment on Whiskey and Dog Toys.

This is the “parody goods” case. VIP Products used the “Bad Spaniels” name to market its dog toys, which were patterned on the distinctive shape of a Jack Daniel’s whiskey bottle.

In December, the Biden administration asserted that it can cite “excessive prices” to justify the exercise of Bayh-Dole march-in rights. The Biden Administration also has continued to support a World Trade Organization TRIPS patent waiver for COVID-19 medicines. These developments are obviously of some concern to pharmaceutical companies and members of the patent bar.

Court Rules AI Training is Fair Use

Court rules that using copyrighted works to train AI is fair use. Kadrey et al. v. Meta Platforms.

Just days after the first major fair use ruling in a generative-AI case, a second court has determined that using copyrighted works to train AI is fair use. Kadrey et al. v. Meta Platforms, No. 3:23-cv-03417-VC (N.D. Cal. June 25, 2025).

The Kadrey v. Meta Platforms Lawsuit

I previously wrote about this lawsuit in an article describing the top 12 generative-AI lawsuits.

Meta Platforms owns and operates social media services including Facebook, Instagram, and WhatsApp. It is also the developer of a large language model (LLM) called “Llama.” One of its releases, Meta AI, is an AI chatbot that utilizes Llama.

To train its AI, Meta obtained data from a wide variety of sources. The company initially pursued licensing deals with book publishers. It turned out, though, that in many cases, individual authors owned the copyrights. Unlike music, no organization handles collective licensing of rights in book content. Meta then downloaded shadow library databases. Instead of licensing works in the databases, Meta decided to just go ahead and use them without securing licenses. To download them more quickly, Meta torrented them using BitTorrent.

Meta trained its AI models to prevent them from “memorizing” and outputting text from the training data, with the result that no more than 50 words and punctuation marks from any given work were reproduced in any given output.

The plaintiffs named in the Complaint are thirteen book authors who have published novels, plays, short stories, memoirs, essays, and nonfiction books. Sarah Silverman, author of The Bedwetter; Junot Diaz, author of The Brief Wondrous Life of Oscar Wao; and Andrew Sean Greer, author of Less, are among the authors named as plaintiffs in the lawsuit. The complaint alleges that Meta downloaded 666 copies of their books without permission and states claims for direct copyright infringement, vicarious copyright infringement, removal of copyright management information in violation of the Digital Millennium Copyright Act (DMCA), and various state law claims. All claims except the ones for direct copyright infringement and violation of the DMCA were dismissed in prior proceedings.

Both sides moved for summary judgment on fair use with respect to the claim that Meta’s use of the copyrighted works to train its AI infringed copyrights. Meta moved for summary judgment on the DMCA claims. Neither side moved for summary judgment on a claim that Meta infringed copyrights by distributing their works (via leeching or seeding).

On June 25, 2025 Judge Chhabria granted Meta’s motion for summary judgment on fair use with respect to AI training; reserved the motion for summary judgment on the DMCA claims for decision in a separate order, and held that the claim of infringing distribution via leeching or seeding “will remain a live issue in the case.”

Judge Chhabria’s Fair Use Analysis

Judge Chhabria analyzed each of the four fair use factors. As is the custom, he treated the first (Character or purpose of the use) and fourth (Effect on the market for the work) factors as the most important of the four.

He disposed of the first factor fairly easily, as Judge Alsup did in Bartz v. Anthropic, finding that the use of copyrighted works to train AI is a transformative use. This finding weighs heavily in favor of fair use. The purpose of Meta’s AI tools is not to generate books for people to read. Indeed, in this case, Meta had installed guardrails to prevent the tools from generating duplicates or near-duplicates of the books on which the AI was trained. Moreover, even if it could allow a user to prompt the creation of a book “in the style of” a specified author, there was no evidence that it could produce an identical work or a work that was substantially similar to one on which it had been trained. And writing styles are not copyrightable.

Significantly, the judge held that the use of shadow libraries to obtain unauthorized copies of books does not necessarily destroy a fair use defense. When the ultimate use to be made of a work is transformative, the downloading of books to further that use is also transformative, the judge wrote. This ruling contrasts with other judges who have intimated that using pirated copies of works weighs against, or may even prevent, a finding of fair use.

Unlike some judges, who tend to consider the fair use analysis over and done if transformative use is found, Judge Chhabria recognized that even if the purpose of the use is transformative, its effect on the market for the infringed work still has to be considered.

3 Ways of Proving Adverse Market Effect

The Order lays out three potential kinds of arguments that may be advanced to establish the adverse effect of an infringing use on the market for the work:

  1. The infringing work creates a market substitute for the work;
  2. Use of the work to train AI without permission deprives copyright owners of a market for licenses to use their works in AI training;
  3. Dilution of the market with competing works.

Market Substitution

In this case, direct market substitution could not be established because Meta had installed guardrails that prevented users from generating copies of works that had been used in the training. Its AI tools were incapable of generating copies of the work that could serve as substitutes for the authors’ works.

The Market for AI Licenses

The court refused to recognize the loss of potential profits from licensing the use of a work for AI training purposes as a cognizable harm.

Market Dilution

The argument here would be that the generation of many works that compete in the same market as the original work on which the AI was trained dilutes the market for the original work. Judge Chhabria described this as indirect market substitution.

The copyright owners in this case, however, focused on the first two arguments. They did not present evidence that Meta’a AI tools were capable of generating books; that they do, in fact, generate books; or that the books they generate or are capable of generating compete with books these authors wrote. There was no evidence of diminished sales of their books.

Market harm cannot be assumed when generated copies are not copies that can serve as substitutes for the specific books claimed to have been infringed. When the output is transformative, as it was in this case, market substitution is not self-evident.

Judge Chhabria chided the plaintiffs for making only a “half-hearted argument” of a significant threat of market harm. He wrote that they presented “no meaningful evidence on market dilution at all.”

Consequently, he ruled that the fourth fair use factor favored Meta.

Conclusion

The decision in this case is as significant for what the court didn’t do as it is for what it did. It handed a fair use victory to Meta. At the same time, though, it did not rule out a finding that training AI tools on copyrighted works is not fair use in an appropriate case. The court left open the possibility that a copyright owner might prevail on a claim that training AI on copyrighted works is not fair use in a different case. And it pointed the way, albeit in dictum, namely, by making a strong showing of market dilution.

That claim is not far-fetched. Scammy AI-Generated Book Rewrites Are Flooding Amazon.
