Does AI Infringe Copyright?

A previous blog post addressed the question whether AI-generated creations are protected by copyright. This could be called the “output question” in the artificial intelligence area of copyright law. Another question is whether using copyright-protected works as input for AI generative processes infringes the copyrights in those works. This could be called the “input question.” Both kinds of questions are now before the courts. Minnesota attorney Tom James describes a framework for analyzing the input question.

The Input Question in AI Copyright Law

by Thomas James, Minnesota attorney

In a previous blog post, I described the top three generative-AI issues in copyright law. The question whether AI-generated creations are protected by copyright is what I call the “output question.” . Another question is whether using copyright-protected works as input for AI generative processes infringes the copyrights in those works. This could be called the “input question.” Both kinds of questions are now before the courts. In this blog post, I describe a framework for analyzing the input question.

The Cases

The Getty Images lawsuit

Getty Images is a stock photograph company. It licenses the right to use the images in its collection to those who wish to use them on their websites or for other purposes. Stability AI is the creator of Stable Diffusion, which is described as a “text-to-image diffusion model capable of generating photo-realistic images given any text input.” In January, 2023, Getty Images initiated legal proceedings in the United Kingdom against Stability AI. Getty Images is claiming that Stability AI violated copyrights by using their images and metadata to train AI software without a license.

The independent artists lawsuit

Another lawsuit raising the question whether AI-generated output infringes copyright has been filed in the United States. In Andersen v. Stability AI, a group of visual artists are seeking class action status for claims against Stability AI, Midjourney Inc. and DeviantArt Inc. The artists claim that the companies use their images to train computers “to produce seemingly new images through a mathematical software process.” They describe AI-generated artwork as “collages” made in violation of copyright owners’ exclusive right to create derivative works.

The GitHut Copilot lawsuit

In November, 2022, a class action lawsuit was filed in a U.S. federal court against GitHub, Microsoft, and OpenAI. The lawsuit claims the GitHut Copilot and OpenAI Codex coding assistant services use existing code to generate new code. By training their AI systems on open source programs, the plaintiffs claim, the defendants have allegedly infringed the rights of developers who have posted code under open-source licenses that require attribution.

How AI Works

AI, of course, stands for artificial intelligence. Almost all AI techniques involve machine learning. Machine learning, in turn, involves using a computer algorithm to make a machine improve its performance over time, without having to pre-program it with specific instructions. Data is input to enable the machine to do this. For example, to teach a machine to create a work in the style of Vincent van Gogh, many instances of van Gogh’s works would be input. The AI program contains numerous nodes that focus on different aspects of an image. Working together, these nodes will then piece together common elements of a van Gogh painting from the images the machine has been given to analyze. After going through many images of van Gogh paintings, the machine “learns” the features of a typical Van Gogh painting. The machine can then generate a new image containing these features.

In the same way, a machine can be programmed to analyze many instances of code and generate new code.

The input question comes down to this: Does creating or using a program that causes a machine to receive information about the characteristics of a creative work or group of works for the purpose of creating a new work that has the same or similar characteristics infringe the copyright in the creative work(s) that the machine uses in this way?

The Exclusive Rights of Copyright Owners

In the United States, the owner of a copyright in a work has the exclusive rights to:

  • reproduce (make copies of) it;
  • distribute copies of it;
  • publicly perform it;
  • publicly display it; and
  • make derivative works based on it.

(17 U.S.C. § 106). A copyright is infringed when a person exercises any of these exclusive rights without the copyright owner’s permission.

Copyright protection extends only to expression, however. Copyright does not protect ideas, facts, processes, methods, systems or principles.

Direct Infringement

Infringement can be either direct or indirect. Direct infringement occurs when somebody directly violates one of the exclusive rights of a copyright owner. Examples would be a musician who performs a copyright-protected song in public without permission, or a cartoonist who creates a comic based on the Batman and Robin characters and stories without permission.

The kind of tool an infringer uses is not of any great moment. A writer who uses word-processing software to write a story that is simply a copy of someone else’s copyright-protected story is no less guilty of infringement merely because the actual typewritten letters were generated using a computer program that directs a machine to reproduce and display typographical characters in the sequence a user selects.

Contributory and Vicarious Infringement

Infringement liability may also arise indirectly. If one person knowingly induces another person to infringe or contributes to the other person’s infringement in some other way, then each of them may be liable for copyright infringement. The person who actually committed the infringing act could be liable for direct infringement. The person who knowingly encouraged, solicited, induced or facilitated the other person’s infringing act(s) could be liable for contributory infringement.

Vicarious infringement occurs when the law holds one person responsible for the conduct of another because of the nature of the legal relationship between them. The employment relationship is the most common example. An employer generally is held responsible for an employee’s conduct,  provided the employee’s acts were performed within the course and scope of the employment. Copyright infringement is not an exception to that rule.

Programmer vs. User

Direct infringement liability

Under U.S. law, machines are treated as extensions of the people who set them in motion. A camera, for example, is an extension of the photographer. Any images a person causes a camera to generate by pushing a button on it is considered the creation of the person who pushed the button, not of the person(s) who manufactured the camera, much less of the camera itself. By the same token, a person who uses the controls on a machine to direct it to copy elements of other people’s works should be considered the creator of the new work so created. If using the program entails instructing the  machine to create an unauthorized derivative work of copyright-protected images, then it would be the user, not the machine or the software writer, who would be at risk of liability for direct copyright infringement.

Contributory infringement liability

Knowingly providing a device or mechanism to people who use it to infringe copyrights creates a risk of liability for contributory copyright infringement. Under Sony Corp. v. Universal City Studios, however, merely distributing a mechanism that people can use to infringe copyrights is not enough for contributory infringement liability to attach, if the mechanism has substantial uses for which copyright infringement liability does not attach. Arguably, AI has many such uses. For example, it might be used to generate new works from public domain works. Or it might be used to create parodies. (Creating a parody is fair use; it should not result in infringement liability.)

The situation is different if a company goes further and induces, solicits or encourages people to use its mechanism to infringe copyrights. Then it may be at risk of contributory liability. As the United States Supreme Court has said, “one who distributes a device with the object of promoting its use to infringe copyright, as shown by clear expression or other affirmative steps taken to foster infringement, is liable for the resulting acts of infringement by third parties.” Metro-Goldwyn-Mayer Studios Inc. v. Grokster, Ltd., 545 U.S. 913, 919 (2005). (Remember Napster?)

Fair Use

If AI-generated output is found to either directly or indirectly infringe copyright(s), the infringer nevertheless might not be held liable, if the infringement amounts to fair use of the copyrighted work(s) that were used as the input for the AI-generated work(s).

Ever since some rap artists began using snippets of copyright-protected music and sound recordings without permission, courts have embarked on a treacherous expedition to articulate a meaningful dividing line between unauthorized derivative works, on one hand, and unauthorized transformative works, on the other. Although the Copyright Act gives copyright owners the exclusive right to create works based on their copyrighted works (called derivative works), courts have held that an unauthorized derivative work may be fair use if it is “transformative.: This has caused a great deal of uncertainty in the law, particularly since the U.S. Copyright Act expressly defines a derivative work as one that transforms another work. (See 17 U.S.C. § 101: “A ‘derivative work’ is a work based upon one or more preexisting works, . . . or any other form in which a work may be recast, transformed, or adapted.” (emphasis added).)

When interpreting and applying the transformative use branch of Fair Use doctrine, courts have issued conflicting and contradictory decisions. As I wrote in another blog post, the U.S. Supreme Court has recently agreed to hear and decide Andy Warhol Foundation for the Visual Arts v. Goldsmith. It is anticipated that the Court will use this case to attempt to clear up all the confusion around the doctrine. It is also possible the Court might take even more drastic action concerning the whole “transformative use” branch of Fair Use.

Some speculate that the questions the Justices asked during oral arguments in Warhol signal a desire to retreat from the expansion of fair use that the “transformativeness” idea spawned. On the other hand, some of the Court’s recent decisions, such as Google v. Oracle, suggest the Court is not particularly worried about large-scale copyright infringing activity, insofar as Fair Use doctrine is concerned.

Conclusion

To date, it does not appear that there is any direct legal precedent in the United States for classifying the use of mass quantities of works as training tools for AI as “fair use.” It seems, however, that there soon will be precedent on that issue, one way or the other. Several lawsuits raising this generative-AI copyright issue are pending in the courts. In the meantime, AI generating system users should proceed with caution.

Newly Public Domain Works 2023

Thousands of books, movies, songs and other creative works entered the public domain in the United States in 2023. Here is a partial list compiled by Cokato Minnesota attorney Thomas James.

Thousands of books, movies, songs and other creative works enter the public domain in the United States this year. Here is a partial list. (Click here for last year’s list).

Sherlock Holmes

Last year, it was Winnie the Pooh. This year, Sherlock Holmes officially enters the public domain. Pooh’s release from copyright protection sparked some creative uses of A. Milne’s fictional bear, from a comic strip in which Pooh Bear appears completely naked (i.e., without his red shirt on) to a slasher film called Winnie the Pooh: Blood and Honey, coming soon to a theater near you.

Sherlock Holmes and his sidekick, Dr. Watson, have actually been in the public domain for a long time, since Arthur Conan Doyle began publishing stories about them in the late nineteenth century. The copyrights in those works had already expired when Congress extended copyright terms in 1998. Legal controversies continued to arise, however, over which elements of those characters were still protected by copyright. New elements that were added in later stories potentially could still be protected by copyright even if the copyrights in previous stories in the series had expired. Now, however, the copyright in the last two Sherlock Holmes stories Doyle wrote have expired. Therefore, it appears that all elements of Doyle’s Sherlock Holmes stories are in the public domain now.

One can only imagine what creative uses people will make of the Holmes and Watson characters now that they are officially in the public domain, too.

Sherlock Holmes, public domain character, illustration in attorney Tom James article on public domain works

The Tower Treasure (Hardy Boys)

The Tower Treasure is the first book in the Hardy Boys series of mystery books that Franklin W. Dixon wrote. As of this year, it is in the public domain.

Again, however, only the elements of the characters and the story in that particular book are in the public domain now. Elements that appeared only in later volumes in the series might still be protected by copyright.

Steppenwolf

Herman Hesse’s Der Steppenwolf, in the original German, is now in the public domain. This version is to be distinguished from English translations of the work, which might still be protected by copyright as derivative works. It is also to be distinguished from the classic rock band by the same name. It is always important to distinguish between trademark and other kinds of uses of a term.

The Bridge of San Luis Rey

Thornton Wilder’s Pulitzer Prize winning novel about an investigation into the lives and deaths of people involved in the collapse of a Peruvian rope bridge has now entered the public domain.

Mosquitoes

William Faulkner’s satiric novel enters the public domain this year. This work is to be distinguished from the insect by the same name. The insect, annoyingly, has been in the public domain for centuries.

The Gangs of New York

Herbert Asbury’s The Gangs of New York is now in the public domain.

Amerika

Franz Kafka’s Amerika (also known as Lost In America) was published posthumously in 1927. It is now in the public domain.

The Jazz Singer

The Jazz Singer is a 1927 American film and one of the first to feature sound. Warner Brothers produced it using the Vitaphone sound-on-disc system and it featured six songs performed by Al Jolson. The short story on which it is based, “The Day of Atonement,” has already been in the public domain for some time. Now the film is, too.

The Battle of the Century

The Laurel and Hardy film, The Battle of the Century, is now in the public domain. Other Laurel and Hardy films, however, may still be protected by copyright.

Metropolis

Science fiction fans are most likely familiar with this 1927 German science fiction silent movie written by Thea von Harbou and Fritz Lang based on von Harbou’s 1925 novel. It was one of the first feature-length movies in that genre. The film is also famous for the phrase, “The Mediator Between the Head and the Hands Must Be the Heart.”

The Lodger

Alfred Hitchcock’s first thriller has entered the public domain.

“We All Scream for Ice Cream”

The song, “I Scream; You Scream; We All Scream for Ice Cream” is now in the public domain. Don’t worry if you uttered this phrase prior to January 1, 2023. Titles and short phrases are not protected by copyright. Now, it would be a different story if you’ve publicly performed the song, or published or recorded the song and/or the lyrics. Merely uttering those words, however, is not a crime.

“Puttin’ on the Ritz”

This song was originally written by Irving Berlin in 1927. Therefore it is now in the public domain. Taco released a performance of a cover version of this song in 1982. This version of the song made it all the way to number 53 in VH1’s 100 Greatest One-Hit Wonders of the 80’s special. Note that even if the original musical composition and lyrics are in the public domain now, recorded performances of the song by particular artists may still be protected. The copyrights in a musical composition and a recording of a performance of it are separate and distinct things. Don’t go copying Taco’s recorded performance of the song without permission. Please.

“My Blue Heaven”

This song, written by Walter Donaldson and George Whiting, is now in the public domain. It was used in the Ziegfeld Follies and was a big hit for crooner Gene Austin. It is not to be confused with the 1990 Steve Martin film with that name, which is still protected by copyright.

“The Best Things In Life Are Free”

This song was written by Buddy DeSylva, Lew Brown and Ray Henderson for the 1927 musical Good News. Many performers have covered it since then. The (ahem) good news is that it is now in the public domain.

Caveats

The works described in this blog post have entered the public domain under U.S. copyright law. The terms of copyrights in other countries are not the same. In the European Union, for example, Herman Hesse’s Der Steppenwolf is still protected by copyright as of January 1, 2023.

And again, remember that even if a work has entered the public domain, new elements first appearing in a derivative work based on it might still be protected by copyright.

Here is an article describing more works that have entered the public domain. 

The featured image in this article is “The Man with the Twisted Lip.” It appeared in The Strand Magazine in December, 1891. The original caption was “The pipe was still between his lips.” The drawing is in the public domain.

 

 

Photographers’ Rights: Warhol Case Tests the Limits of Transformative Use

The U.S. Supreme Court will soon hear Andy Warhol Foundation for the Visual Arts v. Goldsmith. Attorney Thomas James explains what is at stake for photographers

In a previous post, I identified the Second Circuit’s decision in Andy Warhol Foundation for the Visual Arts v. Goldsmith as one of the three top copyright cases of 2021. It has since been appealed to the United States Supreme Court. Oral argument is scheduled for October 12, 2022.

The dispute

The underlying facts in the case, in a nutshell, are these:

Lynn Goldsmith took a photograph of Prince in her studio in 1981. Later, Andy Warhol created a series of silkscreen prints and pencil illustrations based on it. The Andy Warhol Foundation sought a declaratory judgment that the artist’s use of the photograph was “fair use.” Goldsmith counterclaimed for copyright infringement. The district court ruled in favor of Warhol and dismissed the photographer’s infringement claim.

The Court of Appeals reversed, holding that the district court misapplied the four “fair use” factors and that the derivative works Warhol created do not qualify as fair use.

The United States Supreme Court granted the Warhol Foundation’s certiorari petition.

The issue

In this case, the U.S. Supreme Court is being called upon to provide guidance on the meaning and scope of “transformative use” as an element of fair use analysis. At what point does an unauthorized, altered copy of a copyrighted work stop being an infringing derivative work and become a “transformative” fair use? This is one of the leading non-AI-related copyright issues I referenced in Enduring (Non-AI) Legal Issues.

The Conundrum

In the chapter on copyright in my book, E-Commerce Law, I predicted a case like this would be coming before the Supreme Court at some point. As I noted there, a tension exists between the Copyright Act’s grant of the exclusive right to authors (or their assignees and licensees) to make modified versions of their works (called “derivative works”), on one hand, and the idea that making modified versions of copyrighted works is transformative fair use, on the other. The notion that making changes to a work that “transform” it into a new work qualifies as fair use obviously threatens to swallow the rule that only the owner of the copyright in a work has the right to make new works based on the work.

Lower courts have not been consistent in their interpretations and approaches to the transformative use concept. The Warhol case presents a wonderful opportunity for the Supreme Court to provide some guidance.

Campell v. Acuff-Rose Music

The “transformative use” saga really begins with the 1994 case, Campbell v. Acuff-Rose Music, Inc., 510 U.S. 569, 579 (1994). Unable to secure a license to include “samples” (copies of portions) of the Roy Orbison song, “Oh Pretty Woman” in a new version they recorded, 2 Live Crew proceeded to record and distribute their version with the unauthorized sampling anyway, invoking “fair use.”

In a decision that took many attorneys and legal scholars by surprise, the Supreme Court held that 2 Live Crew did not need permission to copy and distribute the work even though the work they created involved substantial copying of the Orbison song. To reach this conclusion, the Court propounded the notion that copying portions of another work — even substantial portions of it — may be permissible if the resulting work is “transformative.” This, the Court held, could hold true sometimes even if the newly created work is not a parody of the original.

In the years that followed, courts have struggled to determine what is a “transformative” modification of a work and what is a non-transformative modification of it. Some courts have demonstrated a willingness to apply the doctrine in such a way as to nearly nullify the exclusivity of an author’s right to make modified versions of his or her works.

Courts have also demonstrated a lack of consistency with respect to how they incorporate and apply “transformativeness” within the four-factor test for fair use set out in 17 U.S.C. Section 107.

Why It Matters

This might seem like an arcane legal issue of little practical significance, but it really isn’t. People are already pushing the transformative use idea into new realms. For example, some tattoo artists have claimed in court filings that they do not need permission to make stencils from photographs because copying a photograph onto skin is a “transformative use.”

Of course, making and distributing exact copies of a photograph for sale in a stream of commerce that directly competes with the original photograph should not be susceptible to a transformative fair use claim. But how far can the claim be carried? If copying a photograph onto somebody’s skin is “transformative” use, would copying it onto somebody’s shirt also be “transformative”?

Clarity and guidance in this area are sorely needed. Hopefully the Supreme Court will take this opportunity to furnish it.

For a case illustrating how the Supreme Court’s decision in Warhol is playing out in the lower courts now, read Nontransformative Nuge.

Newly Public Domain Works

The Cokato Copyright Attorney shares excerpts from selected works that are in the public domain now.

by Minnesota attorney Thomas James (not Ernest Hemingway, the guy in the picture)

I am, of course, late with this. Where other writers have simply listed works by author, title and description, however, this article includes quotations from them. Does it get any better than this? I think not. 

Why are they public domain now?

Copyright protection is not eternal. It only lasts for the number of years specified by law. After that, the work is said to have entered the public domain, meaning that anyone may copy, distribute, perform, display or make new works from it.

In the United States, the U.K., Russia, and most of the European Union, a copyright lasts for 70 years after the author’s death. Accordingly, the works of authors who died in 1951 are now in the public domain. In Canada and most of Asia and Africa, copyrights last for 50 years after the author’s death.

Different rules apply to older works. I explain these in more detail in my books. For our purposes here, we can safely say that U.S. works first published in or before 1926 are now in the public domain, and all pre-1923 sound recordings are now in the public domain.

These rules are subject to exceptions. For example, the U.S. terms of copyright for works made for hire are different from the terms of copyright for other kinds of works.

Learn about some of the other works that have entered the public domain.

Derivative works might not be in the public domain

I have seen a lot of articles declaring that when a work enters the public domain, people no longer need to worry about being sued for copyright infringement. Technically speaking, this is true, but it is important to clearly identify the version of the work that is in the public domain.

Suppose Arthur Conan Doyle published a “Sherlock Holmes” mystery prior to 1923. Suppose, further, that he published a sequel to it in 1928. In the sequel, he added certain details that did not appear in the previous version. If you were to try your hand at writing a Holmes mystery now, and you included some of the details that first appeared in the 1928 story, then you may be guilty of copyright infringement.

Similarly, the fact that the original Winnie the Pooh story is now in the public domain does not mean that movies based on the book are, too. A derivative work may still be copyright-protected even after the work on which it is based has entered the public domain.

Here is a small sampling of some of the many works that are in the public domain this year.

Notes on Democracy

“Under the pressure of fanaticism, and with the mob complacently applauding the show,democratic law tends more and more to be grounded upon the maxim that every citizen is,by nature, a traitor, a libertine, and a scoundrel.In order to dissuade him from his evil-doing the police power is extended until it surpasses anything ever heard of in the oriental monarchies of antiquity.”

NFTs and Copyright

The rise in popularity of nonfungible tokens (NFTs) has generated considerable controversy and confusion about whether and how copyright law applies to them. In this article, Cokato, Minnesota attorney Thomas James discusses the interplay between NFTs and U.S. copyright law.

by Minnesota attorney Thomas James

The rise in popularity of nonfungible tokens (NFTs) has generated considerable controversy and confusion about whether and how copyright law applies to them. In this article, Cokato, Minnesota attorney Thomas James explains what they are and discusses the interplay between NFTs and U.S. copyright law.

 

Just for fun, call up an attorney and say, “Hey, I‘ve got a quick question for you. Can I make, sell and buy NFTs without getting into copyright trouble?” Depending on the attorney’s age, area of practice, and musical tastes, the answers you get may be anything from “What makes you think that selling shares of the Nichiyu Forklift Thailand company could raise copyright issues?” to “The answer, my friend, is blowing in the wind” – and many variants in between.

(More probably, someone other than the attorney would answer the phone and ask, “Would you like to set up an appointment?” That, however, would not help to make the point.)

Incidentally, don’t really make a telephone call like this “just for fun.” I was only joking I wouldn’t want you to incur unnecessary legal fees or be accused of making an unwanted or disturbing telephone call.

The point is that many members of the legal profession are scrambling just as much as everybody else is to understand NFTs and how copyright laws apply to them. The aim of this article is to reduce some of the confusion by shedding some light on what NFTs are and how copyright laws may apply to them.

What are NFTs?

NFT stands for “non-fungible token.”

Great. Now what the heck is that? Well, let’s break it down.

Fungible vs. Non-fungible

An item is said to be “fungible” if it is interchangeable with similar items. For example, if a retailer orders 100 pounds of red potatoes from a wholesaler, the contract is most likely one for the purchase of fungible goods. The retailer most likely has not specifically identified any particular potato that must be included in the batch, so long as they’re all of merchantable quality. By contrast, if an art collector enters into a contract to purchase an original painting by Peter Doig, it is almost certainly going to be a contract for a non-fungible product (the painting.) The buyer of a non-fungible item wants a specifically identified item.

Currency is a good illustration of the difference. When you cash a check at a bank, you don’t really care which particular bills and coins you are given in exchange for the check, so long as the amount you are given is equal to the amount specified on the check. The currency in this situation is fungible. By contrast, if you present a check for $4 million dollars to a rare coin vendor to purchase a 1913 Liberty V nickel, you would not consider it acceptable for the vendor to give you a standard-issue 2019 nickel in its place. The rare coin in this example is not fungible, i.e., it is non-fungible.

Tokens

A token is something that represents or stands for something else. New York City old-timers may recall subway tokens – small, coin-shaped objects representing the right of access to a subway train. Casino chips are tokens representing specified amounts of money.

A digital token is a programmable digital unit that is recorded on a digital ledger using blockchain technology. There are a lot of different kinds of digital tokens. They can represent physical goods or digital goods.

Bitcoins are examples of fungible digital tokens. Digital NFTs, on the other hand, most commonly represent art, a photograph, music, a video, a meme, or a digitized scan of some other kind. Cryptopunks, pixelated images of characters each one of which is unique and different from others, are some of the earliest NFTs, but many other examples abound.

Ethereum has developed standards for digital tokens. The ERC-721 standard governs digital NFTs. Under this standard, every NFT must have a tokenID. The tokenID is generated when the token is created. Every NFT also must have a contract address. This is a blockchain address that can be viewed using a blockchain scanner. The combination of tokenID and contract address is unique for each NFT.

Blockchains

Both fungible and nonfungible tokens are built and reside on blockchains. A blockchain is simply a database that stores information in digital format. Think of them as digital ledgers. They are called “block” chains because information is stored in groups (“blocks”). When a block reaches its storage capacity, it is closed and linked to the previously filled block. A new block will be formed for any new data that is added later. As this process repeats, a chain of records is created. Hence the “chain” in blockchain. Each block is time-stamped.

Blockchains are simply record-keeping mechanisms. They work well for many, but not all, kinds of digital files. They play a significant role in cryptocurrency systems, as they maintain a secure, decentralized record of transactions. They are not as efficient, however, for large digital files like artwork, videos, sound recordings, and so on. In these cases, a nonfungible token, not the actual file, can be made a part of the chain. This is why, in addition to a tokenID and contract address, an NFT will frequently contain the creator’s wallet address and a link to the work the token represents.

One of the most important things to remember about NFTs, for purposes of copyright law, is that although they might contain a creative work within them, more typically they link to a work in some way. They are pieces of code containing a link; they are not typically the works themselves.  

Transfers of NFTs vs. transfers of copyrights

NFTs representing artwork sometimes sell for millions of dollars. Perhaps this explains the popular misconception that the copyright in the work the NFT represents gets transferred along with the NFT. No, buying an NFT representing a work of art does not, by itself, give the buyer the rights of a copyright owner. You might think that you must be getting something more than a string of code when you buy an NFT, but no. In the United States anyway, an assignment of copyright must be express and made in a writing signed by the copyright owner (or the copyright owner’s authorized agent.)

Of course, if a written contract does expressly provide for the assignment of the copyright, then a transfer of a copyright may co-occur with the transfer of an NFT. In the absence of such a contractual provision, however, buying an NFT does not transfer the copyright in the artwork it represents. Instead, it operates in a way similar to the way buying a copy of a copyrighted book or a print of copyrighted artwork does.

The question whether the transfer of an NFT gives the transferee a copyright license is a little more complicated.

In the United States, an exclusive copyright license, like an outright transfer, must be in writing. A non-exclusive license, on the other hand, may be either express or implied. In addition, it is possible to code any type of agreement into a smart contract (an agreement that is written in code and stored on a blockchain.) If the existence of a valid copyright license can be proven, then the nature and extent of the NFT transferee’s rights may be governed by its terms.

A U.S. federal court had occasion to address the subject of implied copyright licenses in the case of Pelaez v. McGraw Hill, 399 F. Supp. 3d 120 (S.D.N.Y. 2019). There, the court ruled that the test for an implied license is whether the parties’ conduct, taken as a whole, demonstrates an intent to grant a license. The court pointed out that an implied license cannot be based on the unilateral expectations of one person. A party’s subjective belief that he or she has been granted a license is not enough. The totality of facts and circumstances must be such that a court could reasonably infer that both parties intended a license.

Copyright ownership arises at the time an original, creative, expressive work is fixed in a tangible medium. Registration is not required. Despite this feature of copyright law, some countries make registration of the copyright a prerequisite to enforcing it in court. The United States is such a country.

Some people believe that because blockchain operates as an unalterable record of ownership, it serves as a substitute for registration with the U.S. Copyright Office. This is not the case.

The U.S. Copyright Act requires the copyright in a domestic work to be registered with the Copyright Office before an infringement claim may be filed in court. 17 U.S.C. § 411. It does not make an exception for cases in which ownership is sought to be proven by a “poor man’s copyright” (i.e., submitting into evidence the postmark on an envelope in which you have mailed a copy of the work to yourself), much less for a digital NFT.

Of course, a registration certificate only creates a presumption of copyright ownership. The presumption is rebuttable. Could evidence such as the date on which an NFT representing the work was created and written into the blockchain be used to rebut that presumption? Possibly. Then again, how probative is that evidence? Anyone can make a false ownership claim and write it into the blockchain, just as anyone can mail an infringing copy of a work to themselves.

Unless Congress amends the Copyright Act to make blockchain a substitute for registration with the Copyright Office, it would be foolhardy to rely on blockchain as a registration alternative.

Infringement

Is minting an NFT associated with a copyrighted work, without permission, infringement? The answer to this question is not as simple as you might think.

The exclusive rights of a copyright owner include reproduction, distribution, public display, public performance, and the making of derivative works. An NFT containing only a tokenID, contract address and a link to a work is merely a string of code associated with a work; it is not the work itself. If an NFT only contains a link to the work, not the work itself, then it is difficult to see how minting an NFT would violate any of the exclusive rights of a copyright owner.

Of course, if the NFT itself contains copyright-protected elements of the work (and this would have to be something more than the title, artist name and a link), then it might be a reproduction or a derivative of the work. In this situation, creating an NFT without the copyright owner’s permission could constitute infringement, since the copyright owner has the exclusive right to make copies and derivatives of the work.

If the link points to a copy or derivative work that the link creator created in violation of the copyright owner’s exclusive rights to make copies and derivative works, then the link creator could incur two kinds of infringement liability. Even if minting an NFT does not itself infringe a copyright, including in it a link to an infringing copy of a copyright-protected work could result in contributory liability for infringement if that person knows or should know that it will facilitate or encourage unauthorized copying (or other unauthorized use) of a copyrighted work. And of course, there would be direct liability for making the copy or the derivative work without the copyright owner’s permission.

The first sale doctrine

Under U.S. copyright law, the purchaser of a lawfully acquired copy of a copyrighted work may resell that copy without first getting the copyright owner’s permission, unless a contract governing the acquisition of the copy provides otherwise. This is why purchasing a paperback copy of The Andromeda Strain on Amazon.com and later reselling it at a garage sale will not subject you to liability for infringing the copyright owner’s exclusive right to distribute copies of the work.

Does the first sale doctrine also apply to NFTs?

The first sale doctrine generally does not apply to resales of digital goods. This is because a sale of a digital file normally will require making a copy of the file. That would violate the copyright owner’s exclusive right to reproduce his or her work. See, e.g., Capitol Records LLC v. ReDigi Inc. (2d Cir. 2018) (refusing to apply the first sale doctrine to the resale of an MP3 file because the resale would require making an unauthorized reproduction of the original MP3 file).

NFTs, however, arguably are distinguishable from MP3 files. A purchaser of an NFT does not buy the digital file containing the copyright-protected work. An NFT buyer simply purchases a token. Reselling a token does not involve reproducing the work itself. cf. Disney Enterprises Inc. v. Redbox Automated Retail LLC (C.D. Cal. Feb. 20, 2018 (first sale doctrine inapplicable to digital download codes because they are options to create a physical copy, not actual sales of copies).

If the transferee of an NFT uses it to access the copyrighted work, and in the course of doing so, the work is reproduced or distributed, then it would seem that the transferee could, at that point, be liable for copyright infringement. There would also appear to be a potential risk of liability for contributory infringement on the part of the NFT seller, at least in some cases.

Of course, this should not be a problem if the copyright owner has authorized resales by NFT buyers.
