Falling Flat: Why Ai Cannot Free Melodies From Copyright Protection With “All The Music” As An Example, Hayley Huber

Duke Law & Technology Review

As artificial intelligence (AI) continues to surprise us with its humanlike abilities, it raises the question of whether AI-created music can or should be afforded legal protection. Particularly, how should copyright law treat melodies produced by an AI designed to algorithmically generate every possible melody? This article seeks to answer that question, ultimately concluding that AI-produced melodies are not copyrightable and that melodies are not merely facts undeserving of copyright protection, but something valuable to mankind and worth protecting by law.

The article explores Damien Riehl’s All the Music project (ATM) and his arguments for why ATM’s outputs should be …

Revisiting Eli Lilly V. Canada: Judicial Interpretation Of Ip Law And Exposure To Investor-State Disputes, Yumu Chen

Duke Law & Technology Review

Eli Lilly v. Canada was an investor-state dispute settlement (ISDS) case widely noted for signaling a regime shift in intellectual property (IP) protection from the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) to ISDS. Its true yet often overlooked significance, however, lies in being a case of first impression on whether judicial interpretation of IP law may serve as a basis for state responsibility independent of denial of justice. To bridge that gap, this Note undertakes a close reading of the novel doctrinal discussion in Eli Lilly and related precedents, drawing implications for the broader theory of state …

Recent Changes In Discretionary Denials Of Drug Patent Challenges, S. Sean Tu, Arti K. Rai, Aaron S. Kesselheim

Faculty Scholarship

Recent policy shifts at the U.S. Patent and Trademark Office (USPTO) have sharply limited the use of two administrative pathways for patent reviews, inter partes review (IPR) and post-grant review (PGR). Congress created these administrative pathways to provide a faster and less costly way to challenge weak patents. Recently, the USPTO has expanded the use of “discretionary denials,” invoking a new “settled expectations” rationale that blocks IPR petitions for patents more than about six years old. From May to September 2025, 60% of 506 requests for discretionary denial were granted, triple historical levels, including one-third involving drug patents. These changes …

The Reliability Response To Patent Law’S Ai Challenges, Arti K. Rai

Faculty Scholarship

Pervasive AI use adds newfound importance to longstanding debates over patent timing and reliability. Patent claims on speculative ideas generated by AI, or even the infusion of speculative AI-generated ideas into the public domain, may defeat patent incentives for more careful research. Although challenges that AI use poses for patent validity requirements like human inventorship and nonobviousness have received more attention, reliability is equally important.

Indeed, as this Article argues, the issues are linked. If requirements for inventorship and nonobviousness were adjusted to emphasize reliability, a human role could be preserved, and AI use would not necessarily threaten patents. Currently, …

Measuring The Value Of Trademark Distinctiveness: Evidence From The Market For Bordeaux Wine, Christopher Buccafusco, Jonathan S. Masur, Ryan Whalen

Faculty Scholarship

The market value of distinctive trademarks is a fundamental assumption of both trademark law and marketing theory. However, there is little empirical evidence underlying this assumption. We examine the relationship between brand dissimilarity and market prices in the context of the Bordeaux wine market. Using a unique dataset covering thousands of wines and their associated prices and professional ratings, we find that brand distinctiveness is related to higher wine prices. We further show that this relationship persists across the wine quality spectrum, with both lower quality and higher quality wines benefiting from dissimilar marks. Finally, we show that while there …

Collective Management Of Copyrights And Human Rights In An Age Of Technological Automation, Laurence R. Helfer, Giulia Priora

Faculty Scholarship

Collective management organizations (CMOs) across the world have remained key to the exercise and enforcement of copyrights and neighbouring rights of individual creators notwithstanding the rapid development of digital technologies and their decentralizing potential. This chapter provides an up-to-date legal analysis on the role and activities carried out by CMOs vis-à-vis the protection of creators’ rights as international human rights. By scrutinizing key treaty provisions and interpretative documents, the analysis reveals how a human rights framework supports numerous functions performed by CMOs. However, significant conflicts may arise from certain practices and policies of CMOs concerning, for example, mandatory membership, promotion …

Trade Secrecy's Information Paradox, Christopher Buccafusco, Jonathan S. Masur, Deepa Varadarajan

Faculty Scholarship

Trade secret law is meant to encourage socially beneficial behaviors by permitting firms to protect their investments in the creation of valuable information. In theory, the ability to protect valuable information will make firms more likely to create that information in the first instance. But the law can also be used to shield socially harmful behaviors from public oversight. Firms can assert trade secret protection to prevent journalists, watchdogs, and criminal defendants from learning whether they are engaged in dangerous, wrongful, or biased activity. Ideally, trade secret law should sort socially beneficial uses from socially harmful ones, permitting only the …

Copyrighting Style, Christopher Buccafusco

Faculty Scholarship

Does copyright law protect an artist’s style? The federal courts that have considered the question are equally split. They all agree, however, that the answer to the question resides in copyright law’s idea/expression distinction. According to this doctrine, ideas, techniques, and methods cannot be copyrighted, but expressions of ideas can be. The question courts have faced, then, is whether artistic style is an idea or a matter of expression. The answer, perhaps unfortunately, is that style is both.

This is unfortunate because, this Article argues, copyright law’s idea/expression distinction is inadequate to the task of determining the copyrightability of style. …

Molecular Diagnostic Patenting After Mayo V. Prometheus: An Empirical Analysis, Colleen V. Chien, Jenna Clark, Arti K. Rai

Faculty Scholarship

Since the United States Supreme Court's 2012 decision in Mayo v. Prometheus announced a new legal test for patent-eligible subject matter, policymakers, and scholars have vigorously debated the decision's impact on molecular diagnostics innovation. Molecular diagnostics serve as the cornerstone of personalized medicine and its promise of treatments with fewer side effects and better outcomes for patients. This article contributes to the presently thin evidence base on the impact of Mayo by using data on patent applications, examinations, and grants from 2010 to 2019 to comprehensively trace the effects of the test and subsequent related developments. Using descriptive data as …

Beyond Patents: Incentive Strategies For Ocean Plastic Remediation Technologies, Jacob Stotser

Duke Law & Technology Review

With a garbage truck’s worth of plastic being dumped in the ocean each minute, there is a dire need for effective technological solutions aimed at mitigating the marine plastic pollution problem. However, the reliance of the U.S. patent system on market demand to incentivize this type of innovation has proven insufficient in light of the peculiarities of “green” technologies. To remedy this, this article proposes a multi-faceted incentivization approach that looks beyond the U.S. Patent and Trademark Office to stimulate the development of remediation technologies through comprehensive regulatory interventions, the establishment of prize funds and other alternative incentive mechanisms, and …

Antisocial Innovation, Christopher Buccafusco, Samuel N. Weinstein

Faculty Scholarship

Innovation is a form of civic religion in the United States. In the popular imagination, innovators are heroic figures. Thomas Edison, Steve Jobs, and (for a while) Elizabeth Holmes were lauded for their vision and drive and seen to embody the American spirit of invention and improvement. For their part, politicians rarely miss a chance to trumpet their vision for boosting innovative activity. Popular and political culture alike treat innovation as an unalloyed good. And the law is deeply committed to fostering innovation, spending billions of dollars a year to make sure society has enough of it. But this sunny …

Anti-Patents, Roy Baharad, Stuart Minor Benjamin, Ehud Gutte

Faculty Scholarship

Conventional wisdom has long perceived the patent and tort systems as separate legal entities, each tasked with a starkly different mission. Patent law rewards novel ideas; tort law deters harmful conduct. Against this backdrop, this Essay uncovers the opposing effects of patent and tort law on innovation, introducing the "injurer-innovator problem." Patent law incentivizes injurers --often uniquely positioned to make technological breakthroughs--by allowing them to profit from licensing their inventions to competitors. Yet tort law, by imposing liability for failures to invest in care, forces injurers to incur the cost of implementing their own innovations. When the cost of self-implementation …

Competition And Congestion In Trademark Law, Christopher Buccafusco, Jonathan S. Masur, Mark P. Mckenna

Faculty Scholarship

Trademark law exists to promote competition. If consumers know which companies make which products, they can more easily find the products they actually want to purchase. Trademark law has long treated “source significance”—the fact that a particular trademark is identified with a particular producer—as both necessary and sufficient for establishing a valid trademark. That is, trademark law has traditionally viewed source significance as the only necessary precondition for a trademark being pro-competitive. In this Article, we argue that this equation of source significance and pro-competitiveness is misguided. Some marks use words that are so closely connected with the product being …

Introducing Biosimilar Competition For Cell And Gene Therapy Products, Brian Canter, Sabine Sussman, Stephen Colvill, Nitzan Arad, Elizabeth Staton, Arti Rai

Faculty Scholarship

This article provides an early analysis of the potential for creating future biosimilar competition for cell and gene therapies (CGTs) to lower prices and improve patient access, building on a unique set of interviews with relevant experts. Our discussion addressed regulatory, manufacturing, intellectual property, and market size challenges. Due to CGTs’ complexity, meeting the regulatory requirement of ‘high similarity with no clinically meaningful differences’ will be difficult. Gene therapies are likely better candidates for biosimilar development than cell therapies. Biosimilarity should be met when gene therapy biosimilars contain the same genetic sequence as a reference product, and the variability in …

A Codified Liability Regime To Stimulate Greater Investment In Subpatentable Innovation, Jerome H. Reichman, Ana Santos Rutschman

Faculty Scholarship

The global intellectual property system rests on a distinction between exclusive property rights and free competition. Exclusive rights vary in strength and intensity, but the opposite of protection is almost always free competition. Distinctions of intensity are drawn in terms of the length of protection given to different subject matters plus variable lists of exceptions and limitations to exclusive rights. But the bottom line is that, when protection is not available under the existing system, free competition prevails, and vice-versa (i.e., where there is exclusivity, free competition is deferred for a specified period of time).

This Article departs from a …

Sharing Pathogen Sequence Data For Global Scientific Research Under The Nagoya Protocol To The Convention On Biological Diversity, Jerome H. Reichman, Carolina Dos S. Ribeiro, George B. Haringhuizen, Paul F. Uhlir

Faculty Scholarship

The Nagoya Protocol to the Convention on Biological Diversity (CBD) has threatened to impede access to genetic resources and related data for cross-border scientific research. In principle, every use of genetic resources would require a set of contracts under the CBD, in a “bilateral” regime. The related transaction costs could overwhelm many transnational research undertakings, affecting even public health responses to outbreaks and epidemics. However, the Nagoya Protocol also offers a unique opportunity to resolve this dilemma, despite struggles to define the meaning and coverage of “digital sequence information.” The coverage of genetic sequence data under the CBD remains controversial …

The Gptjudge: Justice In A Generative Ai World, Maura R. Grossman, Paul W. Grimm, Daniel G. Brown, Molly (Yiming) Xu

Duke Law & Technology Review

Generative AI (“GenAI”) systems such as ChatGPT recently have developed to the point where they can produce computer-generated text and images that are difficult to differentiate from human-generated text and images. Similarly, evidentiary materials such as documents, videos, and audio recordings that are AI-generated are becoming increasingly difficult to differentiate from those that are not AI-generated. These technological advancements present significant challenges to parties, their counsel, and the courts in determining whether evidence is authentic or fake. Moreover, the explosive proliferation and use of GenAI applications raises concerns about whether litigation costs will dramatically increase as parties are forced to …

Causation And Conception In American Inventorship, Dan L. Burk

Duke Law & Technology Review

Increasing use of machine learning or “artificial intelligence” (AI) software systems in technical innovation has led some to speculate that perhaps machines might be considered inventors under patent law. While U.S. patent doctrine decisively precludes such a bizarre and counterproductive result, the speculation leads to a more fruitful inquiry about the role of causation in the law of inventorship. U.S. law has almost entirely disregarded causation in determining inventorship, with very few exceptions, some of which are surprising. In this essay, I examine those exceptions to inventive causality, the role they play in determining inventorship, and their effect in excluding …

Covid Vaccines And Intellectual Property Rights: Evaluating The Potential For National Legislation Implementing Global Patent Waivers, Ashley Dabiere

Duke Law & Technology Review

Debates over the proper scope of intellectual property protections during the COVID-19 pandemic have occupied newspaper headlines since the first vaccines were developed nearly three years ago. Scholars and key politicians from several nations considered the implementation of a global patent waiver in an effort to make the vaccines more widely available in developing parts of the world. Although the question of whether such a waiver would fulfill this goal remains empirically unanswered and up for debate, the legal structure of United States patent law would make its implementation by Congress difficult given the value placed on intellectual property protections …

Of Bass Notes And Base Rates: Avoiding Mistaken Inferences About Copying, Christopher Buccafusco, Rebecca Tushnet

Faculty Scholarship

To prove copyright infringement, a plaintiff must convince a jury that the defendant copied from the plaintiff’s work rather than independently creating it. To prove copying, especially cases involving music, it’s common for plaintiffs and their experts to argue that the similarities between the parties’ creative works are so great that it is simply implausible that the defendant’s work was created without copying from the plaintiff’s work. Unfortunately, in its present form, the argument is mathematically illiterate: It assumes, without any underlying evidence, that the experts know or could reasonably estimate how likely it is that a song with similarity …

Brief Of Intellectual Property Law Professors And Scholars As Amici Curiae In Support Of The Respondents, Bernard Chao, Kevin Emerson Collins, Christopher A. Cotropia, Charles Duan, Oskar Liivak, Joseph Scott Miller, Arti K. Rai, Michael S. Sinha, S. Sean Tu, Liza Vertinsky

Faculty Scholarship

This amicus brief was written in support of Sanofi (generic pharmaceutical firm). The brief explains why patent claims cannot exceed the scope of what was disclosed in the patent specification. The brief argues that when a patentee invents narrowly, meaning they find and disclose only a limited set of solutions and where they cannot provide a generalizable principle that unites a broader set of solutions, then that inventor has not invented broadly. Accordingly, their claims should be limited to what was explicitly disclosed.

Cryptic Patent Reform Through The Inflation Reduction Act, Arti K. Rai, Rachel E. Sachs, W. Nicholson Price Ii

Faculty Scholarship

If a statute substantially changes the way patents work in an industry where patents are central, but says almost nothing about patents, is it patent reform? We argue the answer is yes — and it’s not a hypothetical question. The Inflation Reduction Act (“IRA”) does not address patents, but its drug pricing provisions are likely to prompt major changes in how patents work in the pharmaceutical industry. For many years scholars have decried industry’s ever-evolving strategies that use combinations of patents to block competition for as long as possible, widely known as “evergreening,” but legislators have not been receptive to …

There's No Such Thing As Independent Creation, And It's A Good Thing, Too, Christopher Buccafusco

Faculty Scholarship

Independent creation is the foundation of U.S. copyright law. A work is only original and, thus, copyrightable to the extent that it is independently created by its author and not copied from another source. And a work can be deemed infringing only if it is not independently created. Moreover, independent creation provides the grounding for all major theoretical justifications for copyright law. Unfortunately, the doctrine cannot bear the substantial weight that has been foisted upon it. This Article argues that copyright law’s independent creation doctrine rests on a set of discarded psychological assumptions about memory, copying, and creativity. When those …

Viagra Did Not Work, But Michael Jordan Still Made It: Trademark Policy Toward The Translation Of Foreign Marks In China, Jyh-An Lee, Lili Yang

Duke Law & Technology Review

Most multinational enterprises (MNEs) register their original trademarks in Roman letters in China upon entering the Chinese market. However, many fail to develop and register corresponding Chinese marks because they do not understand local culture and consumers, overvalue consumers’ presumed brand loyalty, or neglect the accompanying trademark issues. This failure enables trademark squatters to register and hold the Chinese marks for ransom or local competitors to free ride on foreign marks using their Chinese translations or transliterations. This Article first introduces the complexity of translating a foreign mark into Chinese, which concerns complex linguistic, cultural, and business challenges. Based on …

Homography Of Inventorship: Dabus And Valuing Inventions, Jordana Goodman

Duke Law & Technology Review

On July 28, 2021, the Device for the Autonomous Bootstrapping of Unified Sentience (“DABUS”) became the first computer to be recognized as a patent inventor. Due to the advocacy of DABUS’s inventor, Dr. Stephen Thaler, the world’s definition of “inventor” has finally fractured – dividing patent regimes between recognition of machine inventorship and lack thereof. This division has sparked many scholarly conversations about inventorship contribution, but none have discussed the implications of a homographic inventorship. This Article addresses the implications of international homographic inventorship – where countries have different notions and rules concerning patent inventorship – and the consequences for …

Post-Grant Adjudication Of Drug Patents: Agency And/Or Court?, Arti K. Rai, Saurabh Vishnubhakat, Jorge Lemus, Erik Hovenkamp

Faculty Scholarship

The America Invents Act of 2011 (AIA) created a robust administrative system—the Patent Trial and Appeal Board (PTAB)—that provides a route for challenging the validity of granted patents outside of district courts. Congress determined that administrative adjudication of the validity of initial patent grants could be cheaper and more scientifically accurate than district court adjudication of such validity.

For private economic value per patent, few areas of technology can match the biopharmaceutical industry. This is particularly true for small-molecule drugs. A billion-dollar drug monopoly may be protected from competition by a relatively small number of patents. Accordingly, the social cost …

Pay-To-Playlist: The Commerce Of Music Streaming, Christopher Buccafusco, Kristelia García

Faculty Scholarship

Payola—sometimes referred to as “pay-for-play”—is the undisclosed payment, or acceptance of payment, in cash or in kind, for promotion of a song, album, or artist. Some form of pay-for-play has existed in the music industry since the nineteenth century. Most prominently, the term has been used to refer to the practice of musicians and record labels paying radio DJs to play certain songs in order to boost their popularity and sales. Since the middle of the twentieth century, the FCC has regulated this behavior—ostensibly because of its propensity to harm consumers and competition—by requiring that broadcasters disclose such payments.

Thank You For Not Publishing (Unexamined Patent Applications), Lidiya Mishchenko

Faculty Scholarship

Since 2000, the U.S. Patent & Trademark Office (“PTO”) has published nearly all patent applications as they are submitted by applicants. Scholars and practitioners have praised this practice for providing timely notice of the potential legal rights the application may eventually cover. But maximizing timeliness and transparency in this way can also create significant costs, which may chill innovation and deter the development and funding of new research areas. This Article explores these often-unrecognized costs of publishing unexamined patent applications and proposes solutions that balance the benefits of early notice with the costs of patent system uncertainty.

Food For Thought: Intellectual Property Protection For Recipes And Food Designs, Kurt M. Saunders, Valerie Flugge

Duke Law & Technology Review

As any chef will tell you, cooking and food preparation is a creative, sometimes innovative, endeavor. Much thought and time is invested in selecting ingredients, developing the process for preparing the dish, and designing an interesting or appealing look and feel for a food item. If this is true, then it should come as no surprise that recipes, food designs, and other culinary creations can be protected by various forms of intellectual property, namely: trade secrets, design and utility patents, trade dress, but usually not copyright. This article considers how intellectual property law has been applied to protect recipes and …
