A New Approach To Patent Reform, Janet Freilich, Michael J. Meurer, Mark Schankerman, Florian Schuett

Faculty Scholarship

Scholars and policy makers have tried for years to solve the tenacious and harmful crisis of low quality, erroneously granted patents. Far from resolving the problem, these determined efforts have resulted in hundreds of conflicting policy proposals, failed Congressional bills, and no way to evaluate the policies’ value or impact or to decide between the overwhelming multiplicity of policies.

This Article provides not only new solutions, but a new approach for designing and assessing policies both in patent law and legal systems more generally. We introduce a formal economic model of the patent system that differs from existing scholarship because …

A Patent And A Prize, Keith N. Hylton

Faculty Scholarship

This paper examines a simple and old question: should innovators receive a patent or a prize? The answer I provide is equally simple: they should receive both. The literature on patents versus prizes has proceeded mostly under the assumption that there should be a choice between a regime of patents and a regime of prizes in which patents fall into the public domain upon award of the prize. There are significant “public choice costs” under the prize plans. By this I mean there are risks of inappropriate transfers to patentees – that is, looting – and of confiscation of patentees, …

Centering Black Women In Patent History, Jessica Silbey

Faculty Scholarship

Professor Kara Swanson’s latest article is a remarkable example of legal historical scholarship that excavates stories from the past to illuminate the present. It is chock full of archival evidence and historical analysis that explains gaps and silences in the United States patent registry as evidence of marginalized inventors–particularly Black women–who should be named inventors but are not.

The article is arresting reading for anyone interested in antebellum history, intellectual property, and the intersection of racism and sexism in law. Mostly, I am grateful to Professor Swanson for doing the obviously very hard work of digging through archives, reading microfiche, …

Nonpatentability Of Business Methods: Legal And Economic Analysis, Peter Menell, Michael J. Meurer

Faculty Scholarship

In this brief filed in Bilski vs. Kappos, pending before the U.S. Supreme Court, we argue that the "useful Arts" limitation of the the Intellectual Property Clause of the U.S.Constitution restricts the scope of Congress's patent power to technological advances. Beyond this constitutional limitation, Congress has not extended patent protection to business methods. The subject matter provision of the 1952 Patent Act merely codified existing subject matter categories and limitations, including the exclusion of business methods. The First Inventor Defense Act of 1999 did not alter this limitation on patentable subject matter. It did not amend the subject matter provision. …

Competition And Innovation: The Breakup Of Ig Farben, Felix Poege

Faculty Scholarship

The relationship between competition and innovation is difficult to disentangle, as exogenous variation in market structure is rare. The 1952 breakup of Germany’s leading chemical company, IG Farben, represents such a disruption. After the Second World War, the Allies occupying Germany imposed the breakup because of IG Farben’s importance for the German war economy instead of standard antitrust concerns. In technology areas where the breakup reduced concentration, patenting increased strongly, driven by domestic firms unrelated to IG Farben. An analysis of patent texts shows that an increased propensity to patent does not drive the effect. Descriptively, IG Farben’s successors increased …

Sy-Stem-Ic Bias: An Exploration Of Gender And Race Representation On University Patents, Jordana Goodman

Faculty Scholarship

People of color and women are underrepresented in science, technology, engineering and math (“STEM”) fields in the United States. Through both intentional and unintentional structural barriers, universities continue to lose valuable intellectual resources by perpetuating a lack of gender, racial, and ethnic diversity as people climb the academic ladder. Identifying racial and gender disparities between university campus populations and their patent representation quantifies the qualitatively observed systemic racism and sexism plaguing STEM. Although many have written about racial and gender underrepresentation in STEM, no author has ever endeavored to simultaneously quantify the racial and gender gap at universities in the …

Homography Of Inventorship: Dabus And Valuing Inventors, Jordana Goodman

Faculty Scholarship

On July 28, 2021, the Device for the Autonomous Bootstrapping of Unified Sentience ("DAB US") became the first computer to be recognized as a patent inventor. Due to the advocacy of DAB US'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 …

Who Benefits?: How The Aia Hurt Deceptively Non-Joined Inventors, Jordana Goodman

Faculty Scholarship

Congress enacted the America Invents Act (“AIA”) to bolster economic development, sustain American innovation, and protect American jobs. This pro-business legislation, however, overlooked one actor critical to any successful innovation endeavor: the inventor. The AIA created access barriers, preventing inventors from efficiently and effectively seeking the entire remedy spectrum to which they are entitled. Paul Morinville and others have opined that the new first-to-file system put small inventors out of business, naming the AIA the single worst disaster in the history of the U.S. patent system. Beyond the filing and subject matter changes, the AIA created fundamental access to justice …

The Procedure Of Patent Eligibility, Paul Gugliuzza

Faculty Scholarship

A decade ago, the patent-eligible subject matter requirement was defunct. Several recent Supreme Court decisions, however, have made eligibility the most important issue in many patent cases. To date, debates over the resurgent doctrine have focused mainly on its substance. Critics contend that the Supreme Court’s case law makes patents too easy to invalidate and discourages innovation. Supporters emphasize that the Court’s decisions help eradicate the overly broad patents often asserted by so-called patent trolls.

Yet one important consequence of eligibility’s revival has been procedural. Because district courts often view eligibility to present a pure question of law, they are—for …

Diffusing New Technology Without Dissipating Rents: Some Historical Case Studies Of Knowledge Sharing, James Bessen, Alessandro Nuvolari

Faculty Scholarship

The diffusion of innovations is supposed to dissipate inventors’ rents. Yet in many documented cases, inventors freely shared knowledge with their competitors. Using a model and case studies, this article explores why sharing did not eliminate inventors’ incentives. Each new technology coexisted with an alternative for one or more decades. This allowed inventors to earn rents while sharing knowledge, attaining major productivity gains. The technology diffusion literature suggests that such circumstances are common during the early stages of a new technology.

Price Discrimination & Intellectual Property, Michael J. Meurer, Ben Depoorter

Faculty Scholarship

This chapter reviews the law and economics literature on intellectual property law and price discrimination. We introduce legal scholars to the wide range of techniques used by intellectual property owners to practice price discrimination; in many cases the link between commercial practice and price discrimination may not be apparent to non-economists. We introduce economists to the many facets of intellectual property law that influence the profitability and practice of price discrimination. The law in this area has complex effects on customer sorting and arbitrage. Intellectual property law offers fertile ground for analysis of policies that facilitate or discourage price discrimination. …

Can A Court Change The Law By Saying Nothing?, Paul Gugliuzza, Mark A. Lemley

Faculty Scholarship

Can an appellate court alter substantive law without writing an opinion? We attempt to answer that question by conducting a novel empirical investigation into how the Federal Circuit has implemented the Supreme Court’s 2014 ruling in Alice v. CLS Bank, the most recent in a series of Supreme Court decisions strengthening patent law’s patentable subject matter requirement. Our dataset includes each one of the Federal Circuit’s more than 100 decisions on patentable subject matter in the three years since Alice, including affirmances issued without an opinion under Federal Circuit Rule 36.

Including those no-opinion affirmances, the Federal Circuit has found …

Heuristic Interventions In The Study Of Intellectual Property, Jessica Silbey

Faculty Scholarship

In this Essay, I review and elaborate on Dan's Burk's On the Sociology of Patenting with three "heuristic interventions" for the study of intellectual property law. These interventions derive from sociology and anthropology, and to some extent also from critical literary theory. Unoriginal in the social sciences, these heuristic interventions remain largely original to the study of law within law schools and traditional legal scholarship (as opposed to the study of law from within the social sciences and humanities). Burk joins a small but growing group of legal scholars, reaching beyond legal doctrinal analysis and the economic analysis of law …

Knowledge Sharing Among Inventors: Some Historical Perspectives, James Bessen, Alessandro Nuvolari

Faculty Scholarship

This chapter documents instances from past centuries where inventors freely shared knowledge of their innovations with other inventors. It is widely believed that such knowledge sharing is a recent development, as in Open Source Software. Our survey shows, instead, that innovators have long practiced “collective invention” at times, including inventions in such key technologies as steam engines, iron, steel, and textiles. Generally, innovator behavior was substantially richer than the heroic portrayal often found in textbooks and museums. Knowledge sharing promoted innovation, sometimes coexisting with patents, at other times, not, suggesting that policy should foster both knowledge sharing and invention incentives.

Alice Corp. V. Cls Bank Int'l, Jordana Goodman

Faculty Scholarship

Congress has the power "to promote the Progress of Science and useful Arts."' Patent law subject matter eligibility under 35 U.S.C. section 101 creates a balance between incentivizing inventors to publicly disclose their knowledge and protecting the public from monopolies on ideas. Allowing inventors to monopolize the basic tools of scientific and technological work might "tend to impede innovation more than it would tend to promote it."² "Laws of nature, natural phenomena, and abstract ideas" constitute unpatentable subject matter under section 101.³ The section 101 inquiry serves as a threshold test to determine if the subject matter of …

Patent Litigation Reform: The Courts, Congress, And The Federal Rules Of Civil Procedure, Paul Gugliuzza

Faculty Scholarship

Barely three years after passing the America Invents Act, Congress is again considering patent reform legislation. At least fourteen patent reform bills were introduced in the recently concluded 113th Congress. Several of those bills focused specifically on patent litigation, proposing, among other things, to impose heightened pleading requirements on plaintiffs, to limit discovery, and to create a presumption that the losing party should pay the winner’s attorneys’ fees. None of the proposals became law, but one of the bills (the Innovation Act) passed the House of Representatives. In addition, scholars continue to call for reform, and Republican members of Congress …

Which Patent Systems Are Better For Inventors?, James Bessen, Grid Thoma

Faculty Scholarship

International comparisons of patent systems are essential to harmonization treaties and to analyze economic growth. Yet these comparisons often rely on little but conventional wisdom. This paper develops an empirical method to compare the economic strength and quality of patent systems by using renewal analysis of matched patents in different countries (same patent family). Comparing patents on the same inventions filed at the EPO for Germany and in the US, we find that the German patents generate substantially greater market power than their US equivalents, especially for small inventors. Also, the average US patent has relatively lower economic value (“quality”).

Brief Of Amici Curiae Law, Business, And Economics Scholars In Alice Corp. V. Cls Bank, No. 13-298, Jason Schultz, Brian Love, James Bessen, Michael J. Meurer

Faculty Scholarship

The Federal Circuit’s expansion of patentable subject matter in the 1990s led to a threefold increase in software patents, many of which contain abstract ideas merely tethered to a general-purpose computer. There is little evidence, however, to suggest this expansion has produced an increase in software innovation. The software industry was highly innovative in the decade immediately prior to this expansion, when the viability of software patentability was unclear and software patents were few. When surveyed, most software developers oppose software patenting, and, in practice, software innovators tend to rely on other tools to capture market share such as first-mover …

Patents At Issue: The Data Behind The Patent Troll Debate, Jonathan H. Ashtor, Michael J. Mazzeo, Samantha Zyontz

Faculty Scholarship

The debate over "patent trolls"' is raging at full tilt and its fury is stoked by fundamental questions about patent assertion. Both sides are struggling to understand which patent assertion practices are consistent with the purpose of patent rights and which are abusive and result in net social costs. This Article addresses patent assertion concretely through empirical analysis of actual infringement awards. In particular, this Article studies all awards granted for findings of patent infringement in U.S. district courts between 1995 and 2011, and, with targeted analyses, focuses on cases involving patent assertion entities ("PAEs"). This Article specifically investigates certain …

Do Npes Matter? Non-Practicing Entities And Patent Litigation Outcomes, Samantha Zyontz, Michael J. Mazzeo, Jonathan H. Ashtor

Faculty Scholarship

It is widely argued that so-called “patent trolls” are corrupting the U.S. patent system and endangering technology innovation and commercialization at large. For example, a recent White House report argued that “trolls” hurt firms of all sizes and advocated for specific policies aimed at curtailing practices thought to be particularly harmful. Yet the existence and extent of any systematic effects of so-called “troll-like” behavior, and the implications of modern patent assertion practices by Non-Practicing Entities (“NPEs”), remains unclear. This article develops novel empirical evidence to inform the debate over NPEs on patent litigation. Specifically, we conduct a large-scale empirical analysis …

Patent Variation: Discerning Diversity Among Patent Functions, Jessica Silbey

Faculty Scholarship

This Article describes and analyzes qualitative interview data collected over a five-year period. The goal of the interviews was to explore the roles of intellectual property (“IP”) in IP rich fields. Interviews were with diverse actors in a wide-range of industries: film, book publishing, visual arts, internet commerce, biology, engineering, chemistry, computer science. The data described and analyzed in this Article focuses on the specific question about the diverse functioning of patents in the subset of interviewees who are scientists and engineers, their lawyers and business partners. The Article proceeds in two parts. Part I describes the empirical dimension of …

A Generation Of Software Patents, James Bessen

Faculty Scholarship

This report examines changes in the patenting behavior of the software industry since the 1990s. It finds that most software firms still do not patent, most software patents are obtained by a few large firms in the software industry or in other industries, and the risk of litigation from software patents continues to increase dramatically. Given these findings, it is hard to conclude that software patents have provided a net social benefit in the software industry.

Patent Litigation And The Internet, Samantha Zyontz, John R. Allison, Emerson H. Tiller, Tristan Bligh

Faculty Scholarship

Patent infringement litigation has not only increased dramatically in frequency over the past few decades,¹ but also has also seen striking growth in both stakes and cost.² Although a relatively rich literature has added much to our understanding of the nature, causes, and consequences of patent litigation during the past two decades,³ many interesting questions remain inadequately addressed. The nuances of and trends in patent litigation in different technology fields and industries, for example, are still understudied.⁴ Litigation of patents on new technologies has likewise received a dearth of attention. Here we seek to help begin …

Sequential Innovation, Patents, And Imitation, James Bessen, Eric Maskin

Faculty Scholarship

How could such industries as software, semiconductors, and computers have been so innovative despite historically weak patent protection? We argue that if innovation is both sequential and complementary--as it certainly has been in those industries--competition can increase firms' future profits thus offsetting short-term dissipation of rents. A simple model also shows that in such a dynamic industry, patent protection may reduce overall innovation and social welfare. The natural experiment that occurred when patent protection was extended to software in the 1980?s provides a test of this model. Standard arguments would predict that R&D intensity and productivity should have increased among …

What's Wrong With The Patent System? Fuzzy Boundaries And The Patent Tax, James Bessen, Michael J. Meurer

Faculty Scholarship

The annual number of patent lawsuits filed in the U.S. has roughly tripled from 1970 to 2004. The number of suits was more or less steady in the 1970s, climbed slowly in the 1980s, and exploded in the 1990s. Why? The usual answers point to (1) the growth of the “new economy” and the concomitant explosion of patenting, (2) the failure of the Patent Office to reject patents on old or obvious inventions, or (3) the rise of the patent troll. There is an element of truth in all these answers, but even collectively they do a poor job explaining …

An Empirical Look At Software Patents, James Bessen, Robert M. Hunt

Faculty Scholarship

U.S. legal changes have made it easier to obtain patents on inventions that use software. Software patents have grown rapidly and now comprise 15 percent of all patents. They are acquired primarily by large manufacturing firms in industries known for strategic patenting; only 5 percent belong to software publishers. The very large increase in software patent propensity over time is not adequately explained by changes in R&D investments, employment of computer programmers, or productivity growth. The residual increase in patent propensity is consistent with a sizeable rise in the cost effectiveness of software patents during the 1990s. We find evidence …

The Value Of U.S. Patents By Owner And Patent Characteristics, James Bessen

Faculty Scholarship

This paper uses renewal data to estimate the value of U.S. patents, controlling for patent and owner characteristics. Estimates of U.S. patent value are substantially larger than estimates for European patents, however, the ratio of U.S. patent value to R&D for firms is only about 3%. Patents issued to small patentees are much less valuable than those issued to large corporations, perhaps reflecting imperfect markets for technology. Litigated patents are more valuable, as are highly cited patents. However, patent citations explain little variance in value, suggesting limits to their use as a measure of patent quality.

A Comment On 'Do Patents Facilitate Financing In The Software Industry?', James Bessen

Faculty Scholarship

'Do Patents Facilitate Financing in the Software Industry?' by Ronald J. Mann contributes empirical evidence to our understanding of how software startups use patents. However, a close examination of the actual empirical findings in this paper points to rather different conclusions than those that Mann draws, namely: few software startups benefit from software patents and patents are not widely used by software firms to obtain venture financing. Indeed, among other things, the paper reports that 80% of venture-financed software startups had no acquired any patents within four years of receiving financing.

Estimates Of Patent Rents From Firm Market Value, James Bessen

Faculty Scholarship

The value of patent rents is an important quantity for policy analysis. However, estimates in the literature based on patent renewals might be understated. Market value regressions could provide validation, but they have not had clear theoretical foundations for estimating patent rents. I develop a simple model to make upper bound estimates of patent rents using regressions on Tobin's Q. I test this on a sample of US firms and find it robust to a variety of considerations. My estimates correspond well with estimates based on patentee behavior outside the pharmaceutical industry, but renewal estimates might be understated for pharmaceuticals.

Patents And The Diffusion Of Technical Information, James Bessen

Faculty Scholarship

Does the disclosure requirement of the patent system encourage the diffusion of inventions? This paper builds a simple model where firms choose between patents and trade secrecy to protect inventions. Diffusion is not necessarily more likely with a patent system nor is the market for technology necessarily greater.
