Existential Copyright And Professional Photography, Jessica Silbey, Eva E. Subotnik, Peter Dicola

Notre Dame Law Review

Intellectual property law has intended benefits, but it also carries certain costs—deliberately so. Skeptics have asked: Why should intellectual property law exist at all? To get traction on that overly broad but still important inquiry, we decided to ask a new, preliminary question: What do creators in a particular industry actually use intellectual property for? In this first-of-its-kind study, we conducted thirty-two in-depth qualitative interviews of photographers about how copyright law functions within their creative and business practices. By learning the actual functions of copyright law on the ground, we can evaluate and contextualize existing theories of intellectual property. More …

Prior Art In The District Court, Stephen Yelderman

Notre Dame Law Review

This Article is an empirical study of the evidence district courts rely upon when invalidating patents. To construct our dataset, we collected every district court ruling, verdict form, and opinion (whether reported or unreported) invalidating a patent claim over a six-and-a-half-year period. We then coded individual invalidity rulings based on the prior art supporting the court’s decision, observing 3320 invalidation events relying on 817 distinct prior art references.

The nature of the prior art relied upon to invalidate patents is relevant to two distinct sets of policy questions. First, this data sheds light on the value of district court litigation …

Prior Art In The District Court, Stephen Yelderman

This article is an empirical study of the evidence district courts rely upon when invalidating patents. To construct our dataset, we collected every district court ruling, verdict form, and opinion (whether reported or unreported) invalidating a patent claim over a six-and-a-half-year period. We then coded individual invalidation events based on the prior art supporting the court’s analysis. In the end, we observed 3,320 invalidation events based on 817 distinct prior art references.

The nature of the prior art relied upon to invalidate patents informs the value of district court litigation as an error correction tool. The public interest in revoking …

Patent Litigators Playing Cowboys And Indians At The Ptab, Michael E. Benson

Notre Dame Law Review Reflection

This Essay concerns a new frontier of crafty strategy to keep patents from review by the Patent Trial and Appeal Board (PTAB)—the invocation of tribal sovereign immunity to prevent the PTAB from obtaining (subject-matter) jurisdiction over the patent invalidity dispute.

Part I of this Essay provides background information about a current case in which the litigant has attempted to use tribal sovereign immunity in order to avoid an inter partes review (IPR) proceeding before the PTAB. Part II provides a brief summary of the current relevant law (tribal, patent, administrative, etc.) pertaining to tribal sovereign immunity in the context of …

Clown Eggs, David Fagundes, Aaron Perzanowski

Notre Dame Law Review

Since 1946, many clowns have recorded their makeup by having it painted on eggs that are kept in a central registry in Wookey Hole, England. This tradition, which continues today, has been referred to alternately as a form of informal copyright registration and a means of protecting clowns’ property in their personae. This Article explores the Clown Egg Register and its surrounding practices from the perspective of law and social norms. In so doing, it makes several contributions. First, it contributes another chapter to the growing literature on the norms-based governance of intellectual property, showing how clowns—like comedians, roller derby …

Why Do Startups Use Trade Secrets?, David S. Levine, Ted Sichelman

Notre Dame Law Review

Empirical studies of the use of trade secrecy are scant, and those focusing on startups, nonexistent. In this Article, we present the first set of data—drawn from the Berkeley Patent Survey—on the use of trade secrets by U.S. startup companies in the software, biotechnology, medical device, and hardware industries. Specifically, we report on the prevalence of trade secrecy usage among startups. Additionally, we assess the importance of trade secrets in relation to other forms of intellectual property protection and barriers to entry, such as patents, copyrights, firstmover advantage, and complementary assets. We segment these results by a variety of factors, …

Property And Equity In Trademark Law, Mark Mckenna

Journal Articles

This essay, delivered as the Nies Lecture at Marquette Law School, focuses on changes in the doctrinal structure of trademark law over the course of the last century — specifically with respect to the relationship between trademark law’s limits and the broader common law of unfair competition. Changes in that relationship, I will argue, meaningfully increased trademark law's emphasis on property — what the plaintiff owns — and deemphasized legal rules that focused on the defendant’s conduct.

Comparative Analysis Of Innovation Failures And Institutions In Context, Mark Mckenna

Journal Articles

Many different legal and non-legal institutions govern and therefore shape knowledge production. It is tempting, given the various types of knowledge, knowledge producers, and systems with and within which knowledge and knowledge producers and users interact, to look for reductionist shortcuts — in general but especially in the context of comparative institutional analysis. The temptation should be resisted for it leads to either what Harold Demsetz called the Nirvana Fallacy or what Elinor Ostrom critiqued as myopic allegories.

We suggest that comparative institutional analysis must be accompanied by comparative failure analysis, by which we mean rigorous and contextual comparative analysis …

Prior Art In Inter Partes Review, Stephen Yelderman

Journal Articles

This Essay is an empirical study of the evidence the Patent Trial and Appeal Board relies upon when cancelling patents in inter partes review. To construct our dataset, we collected every final written decision invalidating a patent claim over a twelve-month period. We coded individual invalidation events on a reference-by-reference, claim-by-claim basis. Drawing on this dataset, we report a number of details about the prior art supporting patent cancellation, including the frequency with which U.S. patents, foreign patents, and printed publications were cited, the frequency with which the invalidating prior art would have been amenable to a pre-filing prior art …

Technical Standards Meet Administrative Law: A Teaching Guide On Incorporation By Reference, Emily S. Bremer

Journal Articles

When an agency incorporates by reference, it promulgates a rule that identifies—but does not reprint—material already published elsewhere. The incorporated materials thus become binding law without actually being printed in the agency's regulations. Sometimes the incorporated materials are privately developed technical standards, which are often copyrighted and available only for a fee. This restriction on access undermines transparency and public participation in the rulemaking process. Finding a solution is challenging because the problem is multidimensional, implicating public policy in the areas of administrative law, federal standards law and policy, and copyright.

This teaching guide is part of module that offers …
