Human Authorship Required: AI Isn’t an Author Under Copyright Act

by Jodi Benassi | Mar 27, 2025 | Copyrights

The US Court of Appeals for the District of Columbia upheld a district court ruling that affirmed the US Copyright Office’s (CO) denial of a copyright application for artwork created by artificial intelligence (AI), reaffirming that human authorship is necessary for copyright registration. Thaler v. Perlmutter, Case No. 23-5233 (D.C. Cir. Mar. 18, 2025) (Millett, Wilkins, Rogers, JJ.)

Stephen Thaler, PhD, created a generative AI system that he named the Creativity Machine. The machine created a picture that Thaler titled, “A Recent Entrance to Paradise.” Thaler applied to the CO for copyright registration for the artwork, listing the Creativity Machine as the author and Thaler as the copyright owner.

The CO denied Thaler’s application because “a human being did not create the work.” Thaler twice sought reconsideration of the application, which the CO denied because the work lacked human authorship. Thaler subsequently sought review in the US District Court for the District of Columbia, which affirmed the CO’s denial of registration. The district court concluded that “[h]uman authorship is a bedrock requirement of copyright.” Thaler appealed.

The DC Circuit reaffirmed that the Creativity Machine could not be considered the author of a copyrighted work. The Copyright Act of 1976 mandates that to be eligible for copyright, a work must be initially authored by a human being. The Court highlighted key provisions of the Copyright Act that only make sense if “author” is interpreted as referring to a human being. For instance:

A copyright is a property right that immediately vests in the author. Since AI cannot own property, it cannot hold copyright.
Copyright protection lasts for the author’s lifetime, but machines do not have lifespans.
Copyright is inheritable, but machines have no surviving spouses or heirs.
Transferring a copyright requires a signature, and machines cannot provide signatures.
Authors of unpublished works are protected regardless of their nationality or domicile, yet machines do not have a domicile or national identity.
Authors have intentions, but machines lack consciousness and cannot form intentions.

The DC Circuit concluded that the statutory provisions, as a whole, make human activity a necessary condition for authorship under the Copyright Act.

The DC Circuit noted that the human authorship requirement is not new, referencing multiple judicial decisions, including those from the Seventh and Ninth Circuits, where appellate courts have consistently ruled that authors must be human.

Practice Note: Only humans, not their tools, can author copyrightable works of art. Images autonomously generated are not eligible for copyright. However, works created by humans who used AI are eligible for copyright depending on the circumstances, how the AI tool operates, and to what degree the AI tool was used to create the final work. Authors whose works are assisted by AI should seek advice of counsel to determine whether their works are copyrightable.

Zone of Natural Expansion Is a Shield, Not a Sword

by Hannah Hurley | Mar 27, 2025 | Trademarks

The US Court of Appeals for the Federal Circuit upheld a Trademark Trial & Appeal Board decision to partially cancel trademarks, ruling that an opposition challenger could not use the zone of natural expansion doctrine to claim priority because the doctrine is strictly defensive. Dollar Financial Group, Inc. v. Brittex Financial, Inc., Case No. 23-1375 (Fed. Cir. Mar. 19, 2025) (Prost, Taranto, Hughes, JJ.)

Dollar Financial Group (DFG) is a loan financing and check cashing business that has used the mark MONEY MART since the 1980s. In 2012, DFG expanded and started using the mark in connection with pawn brokerage and pawn shop services. DFG registered MONEY MART for these new services in 2014. Brittex petitioned to cancel the registration on several grounds, including that the registrations were improperly issued in violation of the Lanham Act, which bars registration of a mark that “so resembles . . . a mark or trade name previously used in the United States by another and not abandoned, as to be likely, when used on or in connection with the goods of the applicant, to cause confusion, or to cause mistake, or to deceive.” 15 U.S.C. § 1052(d). Brittex has operated pawn shops under the names Money Mart Pawn and Money Mart Pawn & Jewelry since the 1990s and claimed prior common law rights to the MONEY MART mark for pawn services.

The Board ruled in favor of Brittex, finding that Brittex had priority over DFG for pawn services due to its earlier use of the mark. The Board also determined that DFG could not rely on the zone of natural expansion doctrine to establish priority because this doctrine is purely defensive and does not grant a proactive right to register a mark on an expanded line of goods or services. The Board also concluded that there was a likelihood of confusion between the marks, given their high similarity and the overlapping nature of the services provided by both parties. DFG appealed.

The Federal Circuit agreed that Brittex had established priority because it was the first to use the MONEY MART mark in connection with pawn services. The Court also rejected DFG’s zone of natural expansion argument, reiterating that the doctrine is defensive and cannot be used to establish priority offensively.

The doctrine of natural expansion, as explained in Orange Bang v. Ole Mexican Foods (TTAB 2015), states that:

[T]he first user of a mark in connection with particular goods or services possesses superior rights in the mark as against subsequent users of the same or similar mark for any goods or services which purchasers might reasonably expect to emanate from it in the normal expansion of its business under the mark.

However, the doctrine does not give the senior mark user an offensive or proactive use.

The Federal Circuit also addressed DFG’s argument regarding the doctrine of tacking, which allows trademark holders to make minor modifications to their own mark while retaining the priority position of the older mark. Tacking is generally permitted [...]

What’s the (Re)issue? Patent Term Extensions for Reissue Patents

by Connor M. Larson | Mar 27, 2025 | Patents

Addressing the calculation of patent term extensions (PTEs) under the Hatch-Waxman Act, the US Court of Appeals for the Federal Circuit affirmed a district court decision that under the act the issue date of the original patent should be used to calculate the extension, not the reissue date. Merck Sharp & Dohme B.V. v. Aurobindo Pharma USA, Inc., Case No. 23-2254 (Fed. Cir. Mar. 13, 2025) (Dyk, Mayer, Reyna, JJ.)

Merck owns a patent that is directed to a class of 6-mercapto-cyclodextrin derivatives. Four months after the patent issued, Merck applied to the US Food & Drug Administration (FDA) for approval of sugammadex, which it intended to market as Bridion®. During FDA’s review of Merck’s new drug application (NDA), Merck filed a reissue application that included narrower claims. The reissue application issued and included all the original claims and 12 additional claims. FDA regulatory review continued throughout the examination of the reissue application and extended almost two years beyond the date the patent reissued. In all, the FDA regulatory review lasted nearly 12 years.

The Hatch-Waxman Act provides owners of patents related to pharmaceutical products a process to extend the term of their patent rights to compensate for time lost during regulatory review of their NDAs. The act contains a clause providing that “the term of a patent . . . shall be extended by the time equal to the regulatory review period . . . occur[ring] after the date the patent is issued.” Having been unable to market the invention covered by the patent for almost 12 years because of FDA’s regulatory review, Merck filed a PTE application for its reissue patent seeking a five-year extension (the maximum allowed under the act) based on the patent’s original issue date. The US Patent & Trademark Office (PTO) agreed and granted the five-year extension.

Between the reissue date and the PTO’s grant of the five-year extension, Aurobindo and other generic manufacturers had filed abbreviated new drug applications (ANDAs) seeking to market generic versions of Bridion®. Merck sued for infringement. At trial, Aurobindo argued that the PTO improperly calculated the PTE by using the original issue date instead of the reissue date because only 686 days of FDA’s regulatory review occurred after the reissue date, as opposed to the almost 12 years which had passed since the initial issue date. The district court disagreed, finding that Aurobindo’s proposed construction “would undermine the purpose of the Hatch-Waxman Act.” Aurobindo appealed.

Aurobindo argued that the act’s reference to “the patent” referred to the reissue patent because that is the patent for which the patentee was seeking term extension. Merck argued that the act’s text, read in light of other patent statutes and the history of patent reissue, required the opposite conclusion (i.e., a PTE based on the original issue date).

The Federal Circuit agreed with Merck, explaining that while the language of the PTE text may be ambiguous, that ambiguity may be resolved by considering the PTE text in light of the history of [...]

When “It’s Obvious” Just Isn’t Enough: Challenger’s Burden to Prove Obviousness

by Keval Amin | Mar 27, 2025 | Patents

The US Court of Appeals for the Federal Circuit affirmed the Patent Trial & Appeal Board’s decision that a patent was not obvious because the petitioner failed to show sufficient support of obviousness based on prior art. AMP Plus, Inc. v. DMF, Inc., Case No. 23-1997 (Fed. Cir. Mar. 19, 2025) (Lourie, Bryson, Reyna, JJ.)

DMF owns a patent directed to a compact recessed lighting system designed for installation in a standard electrical junction box. In 2019, AMP, doing business as ELCO, petitioned for inter partes review of several claims of the patent on three grounds of unpatentability:

Anticipation by a prior reference
Obviousness based on a combination of two references
Further obviousness based on an additional source.

The Board found that one claim was anticipated but ruled that ELCO failed to prove unpatentability of the other claims, including the claim at issue on appeal. The claim at issue describes a system with wires connected to a driver and a first connector, coupled to a second connector that in turn is connected to the building’s electrical system. This specific connection was referred to as “Limitation M.” ELCO appealed. In that earlier appeal (2022), the Federal Circuit affirmed the Board’s ruling on all claims except the claim at issue and remanded the case back to the Board for further analysis.

On remand, the Board concluded that ELCO failed to demonstrate the unpatentability of the claim at issue because ELCO’s petition lacked a substantive analysis of Limitation M. The Board found ELCO’s argument that a prior art marine lighting system could be adapted for the claimed building use unsupported by evidence and ruled that the claim at issue was not obvious. Again, ELCO appealed.

ELCO raised two main arguments. First, it argued that the Board erred in not determining that the claim at issue was anticipated by a prior reference, as the Board had previously found another claim to be anticipated by the same reference. The Federal Circuit rejected this argument because ELCO had only challenged the claim at issue on the basis of obviousness in its original petition, not anticipation. Since the issue of anticipation was not raised in the petition, the Court determined that ELCO could not introduce this new ground of unpatentability on appeal.

Second, ELCO argued that its petition had sufficiently demonstrated the obviousness of Limitation M based on the prior references. The Federal Circuit disagreed, finding that ELCO’s petition did not adequately address the specific requirement for coupling the system to a building’s electrical infrastructure. The petition failed to discuss how the recessed lighting system would be installed in a building, and the references cited did not provide adequate support for the argument of obviousness for this particular limitation.

The Federal Circuit emphasized that it was not the Board’s responsibility to supplement the petitioner’s arguments or search for evidence to support an inadequately supported claim challenge. The Court reiterated that an obviousness analysis does not require the Board to fill gaps in the petitioner’s original [...]

Even Jepson Preambles Require Written Description Support

by Tessa Kroll | Mar 27, 2025 | Patents

The US Court of Appeals for the Federal Circuit found a Jepson claim unpatentable where the specification did not provide adequate written description for the portion of the claim purporting to recite what was already well known in the prior art. In re Xencor, Inc., Case No. 24-1870 (Fed. Cir. Mar. 13, 2025) (Hughes, Stark, Schroeder, JJ.)

Xencor filed a patent application claiming a modified anti-C5 antibody treatment with certain amino acid substitutions that provide for longer serum half-lives and reduce the need for more frequent treatment. The application included:

A Jepson claim reciting, “[i]n a method of treating a patient by administering an anti-C5 antibody with an Fc domain, the improvement comprising” certain amino acid substitutions, wherein the modified antibody has “increased in vivo half-life.”
A non-Jepson claim directed to “a method of treating a patient by administering an anti-C5 antibody comprising” certain amino acid substitutions, wherein the modified antibody “has increased in vivo half-life.”

The specification provided one example of an anti-C5 antibody, 5G1.1, and three high-level examples of potential uses for anti-C5 antibodies. The examiner rejected the claims for lack of written description. Xencor unsuccessfully appealed the rejection to the Patent Trial & Appeal Board. Xencor then unsuccessfully petitioned the Board for reconsideration. Xencor appealed to the Federal Circuit, which resulted in a remand to the Board’s Appeals Review Panel (ARP).

The ARP concluded that Jepson claim preambles require written description support and that the preamble language of “treating a patient” was limiting – even without the Jepson claim format – because it gave life and meaning to the claim recitations “increased in vivo half-life” and “administering.” Because the specification did not provide a representative number of species to support the broad genus of anti-C5 antibodies, a description of conditions that can successfully be treated with an anti-C5 antibody, or even a single working example describing treatment with an anti-C5 antibody with the claimed modifications, the ARP found that the claims lacked written description and that Xencor had not shown that anti-C5 antibodies were well known. Xencor again appealed, arguing that “treating a patient” was not limiting and that Jepson preambles do not require written description support.

With respect to the preamble of the method claim, the Federal Circuit noted that Xencor agreed that the “administering” portion was limiting but nonetheless argued that “treating a patient” was not. Although a preamble can be split into limiting and non-limiting parts, the Court reasoned that the preamble here could not be neatly packaged into separate portions because the phrase “treating a patient” was directly connected through the word “by” to the phrase “administering an anti-C5 antibody,” and each phrase gave meaning to the other. The Court further explained that the entire preamble provided the raison d’être of the claimed method: When a patient is treated with the modified anti-C5 antibody, the treatment lasts longer, reducing the frequency of treatments. Accordingly, the Court agreed with the ARP that the recitation “treating a patient” was limiting.

The Federal Circuit [...]
