Ai Slop, Jessica Silbey, Woodrow Hartzog

Faculty Scholarship

The term “AI slop” has become popular to describe the output of generative AI systems seen as voluminous, low quality, or the result of little effort. When AI-generated music and videos flood platforms, they are called slop. Peer-reviewed journals and legal tribunals are drowning in low-quality and low-reliability AI slop submissions.  Employees are seen to be producing mountains of slop in their reports and communications with each other. The term has inertia and heft, and the phenomenon has significant consequences. Most of them are not good.

But the boundaries of “AI slop” and its usefulness in policy discussions are not …

Trademarks, Functionality, And Competition, Glynn Lunney

Faculty Scholarship

Courts and commentators have long thought that the purpose of trademark and unfair competition law is to distinguish fair competition from unfair competition and prohibit the latter. Yet, trademark law has a more fundamental, more foundational purpose. Before trademark law can distinguish fair competition from unfair competition, there must first be competition. That makes ensuring competition trademark law’s highest priority. Identifying and prohibiting unfair competition becomes, by necessity, a subordinate concern. Until 1982, courts recognized this hierarchy and enforced a broad and flexible functionality limitation on trademark or trade dress protection to ensure competitive markets. In 1982, however, this changed. …

Modification Patents Across Multiple Ndas In Pharmaceutical Protections, Robin C. Feldman, Ramy Alsaffar, Tanziuzzaman Sakib

Faculty Scholarship

Introduction Our study examines modification patents across multiple New Drug Applications (NDAs), employed by pharmaceutical companies to extend patent protections. Ours is the only comprehensive study of modification patents by Active Pharmaceutical Ingredient (API) across multiple NDAs, the approach of current regulatory initiatives, investigating how these patents extend drug protections and impede generic entry.

Methods We examine 1028 modification patents, categorizing them as chemical variations, formulation changes, treatment methods, or device/agent. We tabulated additional granted protection time, correlations with new NDAs, and litigation from potential generics.

Results On average, 5 modification patents protected each drug, extending granted protection periods by …

Reflections On The Use And Misuse Of Economic Analysis In Copyright, Glynn Lunney

Faculty Scholarship

Economic analysis has long been used to justify copyright regulation. Long before the Statute of Anne, the Stationer’s Guild told the story of the copying competitor, who in the absence of regulation, would copy every original book and offer it for less. In the story, the coping competitor would, in the absence of regulation, deprive the original author of an opportunity to recoup their authorship investment, and so lead to a world where no books at all would be published. To ensure sufficient incentives for authorship, some degree of copyright regulation was thought essential. At the same time, in the …

Tear Down The Wall: Why Requiring The Fda And The Pto To Share Information Will Improve The Decision-Making Of Both Agencies, Robin C. Feldman, Gideon Schor

Faculty Scholarship

An invisible wall separates the U.S. Food and Drug Administration (FDA) from the U.S. Patent and Trademark Office (PTO). This wall blocks inter-agency communication, depriving the PTO of information relevant to patent applications and depriving the FDA of information relevant to drug-approval applications. Consequently, it is too easy for a drug company to tell the PTO ‘our drug is new’ (in hopes of speeding a patent grant) while telling the FDA ‘our drug is not new’ (in hopes of speeding drug approval). Better communication between the FDA and PTO would increase agency accuracy by preventing inconsistent representations, and would increase …

The Eunomics Of Intellectual Property, Shyamkrishna Balganesh

Faculty Scholarship

Originally developed by the legal theorist Lon L. Fuller, eunomics is the “study of good order and workable arrangements,” directed at understanding the structure, form, or ordering adopted by an area of law. Yet, unlike the ordinary analysis of institutional design, eunomics views the form adopted by an area of law as neither preordained nor wholly contingent. Instead, eunomics sees form as playing an important role in clarifying and developing the goals of an area through a means-ends interaction. This Article develops the central insights of Fuller’s eunomics project for intellectual property. Until now, most theoretical accounts of intellectual property …

A Public Trust Theory Of Government Information, Sharon Sandeen

Faculty Scholarship

In the sixth century, the Roman Emperor Justinian declared that certain resources should be for the benefit of all of mankind, thereby planting the seeds of what is referred to as the public trust doctrine. Two core ideas behind the doctrine, which have evolved and expanded over time, are: (1) there are certain critical resources that should be available for all to use; and (2) governments that own or control those resources should preserve and manage them for the public good.

As insightful as Justinian was, his vision was naturally constrained by the times in which he lived, which was …

Open Secrets, Robin C. Feldman, Vaughn Goehrig

Faculty Scholarship

Patents and trade secrets were never intended to meet, but in the world of biologic drugs, they've become as thick as thieves. Patent law's disclosure requirement has demanded far too little of biologics manufacturers-allowing them to keep vital manufacturing details under trade secret lock and key. This intellectual property patchwork has been devastating for drug affordability: Because the most critical manufacturing information remains hidden, makers of follow-on biologics (called biosimilars) are often stuck reinventing the wheel, even after the original patents have expired.

This Article makes two principal contributions to illuminating this problem. First, it presents, for the first time …

Copyright, Incentives, And Popular Music Composition, Glynn S. Lunney Jr.

Faculty Scholarship

The rise of file sharing and the subsequent collapse in sales of recorded music offer a rare glimpse into a counterfactual world where copyright, for a time, was weakened. Comparing creative output before and after this exogenous shock allows us to test empirically whether incentives to copyright owners were correlated with creative output. In this article, I extend previous work on this issue from recording artists to songwriters and search for a correlation between incentives and popular music composition. In particular, I test three hypotheses. First, I test whether more incentives were associated with more or better popular musical compositions. …

Readers Are Authors, Especially In The Ai Age, Jessica Silbey

Faculty Scholarship

In this essay, Abraham Drassinower updates the argument in his 2015 book What’s Wrong With Copying (Harvard University Press) with an elaboration of the nature of copyright’s public domain: it is a domain of unauthorized yet lawful copying. As in his book, Drassinower explains that the public domain is not properly understood as a problem of balancing between copyright’s public benefits and private rewards. Instead, he understands the public domain as part of authorship and thus inseparable from copyright’s construction.

Trips And Its Futures, Peter K. Yu

Faculty Scholarship

The Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS Agreement) was adopted on 15 April 1994, along with the estab-lishment of the World Trade Organization (WTO). With the WTO’s recent celebration of its thirtieth anniversary, it is high time we explore what the future will hold for this agreement. This chapter begins by revisiting the past to examine whether the TRIPS Agreement would be adopted if it were negotiated today. The chapter then discusses whether WTO members will undertake a major overhaul of this agreement in the future. Taking note of the fast-evolving international norm-setting environment and …

De Minimis Copying: An Empirical Study, Jessica Silbey, Samantha Zyontz

Faculty Scholarship

In the internet age, the copyright de minimis defense has increased in relevance as copyright lawsuits (and IP generally) are more mainstream and infringement liability more widespread. This Article is the first empirical analysis of copyright de minimis defense cases, collecting and analyzing all such decisions since the mid-19th century. It traces the doctrine’s development over the past century and its evolution in the digital era, when copying has become even more ubiquitous but its triviality remains widely disputed. The Article’s aim is not only to map the de minimis defense to learn more about it doctrinally—asking when is copying …

The Complex Interplay Between Intellectual Property And The Right To Science, Peter K. Yu

Faculty Scholarship

In April 2020, the U.N. Committee on Economic, Social and Cultural Rights released General Comment No. 25, which provides an authoritative interpretation of the right to science—a right that has hitherto not received much attention. In light of this publication and the recent celebration of the 75th anniversary of the Universal Declaration of Human Rights, this article examines the complex interplay between intellectual property and the right to science, with a view toward the human rights challenges brought about by both the COVID-19 pandemic and the arrival of generative AI.

The article begins by documenting the historical evolution of the …

Deepfakes In Domestic And International Perspective, Jane C. Ginsburg, Graeme W. Austin

Faculty Scholarship

Have you always (or ever) yearned to produce your own recording of Elvis Presley singing great baritone arias from Italian opera? Or to make a movie starring Nicole Kidman as Lady Macbeth? Or a videogame featuring the bully who tormented you in high school suffering repeated tortures worthy of the Christian martyrdoms recounted with gusto in The Golden Legend? You can fulfill all these wishes, and more, thanks to the AI technology enabling the creation of “deepfakes” — known in legal documents as “digital replicas” — capable of simulating the visual and vocal appearance of real people, living or …

The Antitrust–Copyright Interface In The Age Of Generative Artificial Intelligence, Daryl Lim, Peter K. Yu

Faculty Scholarship

The U.S. government's antitrust actions against Big Tech have recently surged in response to the growing dominance of Amazon, Apple, Google, Meta, and Microsoft. In fall 2023, the Federal Trade Commission filed a controversial submission in response to the U.S. Copyright Office's request for comments on artificial intelligence (AI) and copyright. This submission hinted at the agency's eagerness to fully deploy its enforcement powers in the AI sector, including targeting AI developers that have used copyrighted works without authorization to train AI models.

This article examines the changing interface of antitrust and copyright law in the age of generative AI. …

Humanist Copyright, Jane C. Ginsburg

Faculty Scholarship

This exploration of the role of authorship in copyright law proceeds in three parts: historical, doctrinal, and predictive. First, I will review the development of author-focused property rights in the pre-copyright regimes of printing privileges and in early Anglo-American copyright law through the 1909 U.S. Copyright Act. Second, I will analyze the extent to which the present U.S. copyright law does (and does not) honor human authorship. Finally, I will consider the potential responses of copyright law to the claims of proprietary rights in AI-generated outputs. I will explain why the humanist orientation of U.S. copyright law validates the position …

Artificial Intelligence, Autonomous Creation, And The Future Path Of Copyright Law, Peter K. Yu

Faculty Scholarship

Most literature at the intersection of copyright and AI has focused primarily on what copyright law is or ought to be. Frequently overlooked is the question of what copyright law will be in the AI space. Understanding this question is crucial because the path of copyright law chosen by the United States will have a major impact on the country's economic and technological future.

This article begins by scrutinizing two lines of arguments that have been advanced to deny copyright protection to AI-generated works: constitutional and incentive-based. The article then discusses a third line of arguments—harmonization-based arguments—and identifies select instances …

Deepfakes Can Ruin Lives And Livelihoods – Would Owning The ‘Rights’ To Our Own Faces And Voices Help?, Graeme W. Austin, Jane C. Ginsburg

Faculty Scholarship

Not that long ago, the term “deepfake” wasn’t in most people’s vocabularies. Now, it is not only commonplace, but is also the focus of intense legal scrutiny around the world.

Known in legal documents as “digital replicas”, deepfakes are created by artificial intelligence (AI) to simulate the visual and vocal appearance of real people, living or dead.

Unregulated, they can do a lot of damage, including financial fraud (already a problem in New Zealand), political disinformation, fake news, and the creation and dissemination of AI-generated pornography and child sexual abuse material.

For professional performers and entertainers, the proliferation and increasing …

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 …

Design Problems, Mark P. Mckenna, Jessica Silbey

Faculty Scholarship

This Essay draws on our empirical research into designers and their work to investigate the limits of intellectual property law for achieving its goal of progress in the design context. We focus on two related aspects of our research and also address a pressing doctrinal question in design patent law. The two research questions we discuss are: (1) How do designers conceive of and solve design problems through innovative design practice?; and (2) How do designers incorporate human values of coherence, inclusivity, and sustainability in their process, imbuing their practice with a kind of politics? The related doctrinal question concerns …

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, …

Law As A Lamp Post, Janet Freilich

Faculty Scholarship

Law produces all manner of public information: court documents, securities filings, patents, property records, and much more. This information is used in a multitude of ways—it teaches readers about individual cases, transactions, or entities, and is also aggregated to inform policymaking, set priorities, and drive predictive analytics and artificial intelligence.

But choices about the information produced (or hidden) by law are often unintentional. Doctrines and institutions that appear facially unrelated to information production—like subject matter jurisdiction—nonetheless affect the shape and quantity of data produced. And even doctrines focused on information— like property recordation—create data used for purposes never envisioned by …

Preventing Unjust Enrichment And Copyright Opportunism: An Equitable Interpretation Of Section 103(A), Pamela Samuelson, Jessica Silbey

Faculty Scholarship

A stealth issue in many close copyright fair use cases is the potential invalidity of second comers’ copyrights under 17 U.S.C. § 103(a) if the secondary use is ultimately held to infringe the derivative work right. Section 103(a) of the Copyright Act says, in effect, that no copyright exists in any part of a derivative work in which the first work’s expression was “used unlawfully.” Courts have largely ignored § 103(a). But recent cases, such as Andy Warhol Foundation for the Visual Arts, Inc. v. Goldsmith (2023), have raised the profile of § 103(a). This Article traces the origins, history, …

How Theories Of Art Can Inform Debates About Ai, Jessica Silbey

Faculty Scholarship

Debates about artificial intelligence (AI) tend to swing between the optimistic and the apocalyptic. I propose a less binary approach that frames conversations about AI from the perspectives of theories of art and creativity. Whether we agree that AI is artificial or intelligent, whether it should be constrained or liberated, we cannot deny its influence on literary, artistic, and innovative production. AI may be described as simply a new tool to produce art and science, like the camera or the microscope, or it may transform art and science, the way the internet transformed global communication. Either way, these debates about …

The Globalization Of Copyright Exceptions For Ai Training, Matthew Sag, Peter K. Yu

Faculty Scholarship

Generative AI, machine learning and other computational uses of copyrighted works pose profound questions for copyright law. This article conducts of global survey of how different countries have attempted to answer these questions in relation to the unauthorized use of copyrighted works for training. Although the world has yet to achieve international consensus on this issue, an international equilibrium is emerging. Jurisdictions with common law and civil law traditions, and with varying economic conditions, technological capabilities, political systems, and cultural backgrounds, have found ways to reconcile copyright law and AI training. In this equilibrium, countries recognize that text data mining, …

Copyright Law And Property Law, Keith N. Hylton

Faculty Scholarship

Property is at the core of state law since it is the exclusive power of the individual state governments to define and protect property rights within their jurisdiction. In this paper I will discuss the general connection between copyright and property generally. I will argue that property law sheds important light on copyright law and can help us cut through modern controversies in copyright law. If I am correct in this view, any judge sufficiently familiar with property law doctrines could do better than the Supreme Court of the United States in resolving a new copyright controversy. Specifically, property law …

Ten Tips For Legal Empiricists, Jordana Goodman, Christa J. Laser, Mark A. Lemley, Lisa Larrimore Ouellette, Melissa F. Wasserman, Saurabh Vishnubhakat, Janet Freilich, Jessica Silbey, David L. Schwartz, Neel U. Sukhatme

Faculty Scholarship

Topics include developing meaningful research questions, designing robust survey methodologies, balancing qualitative and quantitative approaches, ensuring data transparency, fostering interdisciplinary collaboration, and navigating ethical considerations in empirical work. Drawing from their own unique challenges and successes, scholars Michael D. Frakes, Janet Freilich, Mark A. Lemley, Lisa Larrimore Ouellette, David L. Schwartz, Jessica Silbey, Neel U. Sukhatme, Saurabh Vishnubhakat, Melissa F. Wasserman, Jordana Goodman, and Christa Laser illuminate what they wished they would have known going into empirical research and the pitfalls …

Do Academic Researchers Care About Patent Infringement? A Pcr Case Study, Janet Freilich

Faculty Scholarship

Because much cutting-edge academic research involves building on other new technologies, university research often involves making or using a patented invention—an act of patent infringement. The problem of how patents affect academic researchers has attracted considerable attention, but legal scholars are divided on the magnitude of patents’ potential impact. Many scholars fear that patents will entirely hobble academic scientific research, while others find that academic researchers entirely ignore patents and thus that they have little impact. This Article adds a piece of empirical evidence to the debate by studying the example of polymerase chain reaction (PCR) technology. In the early …

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 …
