The Case Of The Missing Device Patents, Or: Why Device Patents Matter, Erika Lietzan, Kristina M. L. Acri, Evan Weidner

Faculty Publications

A company that earns premarket approval of its medical device is entitled to an extension of one patent claiming the device, to make up for some of the time it spent doing premarket research. Yet, surprisingly, a mere thirteen percent of those eligible for this extension (also known as patent term "restoration") ask for one. In contrast, most drug companies entitled to this same patent extension ask for one.

In this Article, we attribute the imbalance largely to differences between the two regulatory frameworks. In brief, because the FDA classifies and regulates devices based on what they do and how …

Solutions Still Searching For A Problem: A Call For Relevant Data To Support "Evergreening" Allegations, Erika Lietzan, Kristina M. L. Acri

Faculty Publications

For years pharmaceutical policymaking discussions have been revolving around allegations of supposed “evergreening” by pharmaceutical companies, and policymakers have considered a range of significant policy reforms — including to antitrust law and drug regulatory law — to address this purported problem. This paper evaluates empirical data offered to substantiate “evergreening” and explains that these data — though mostly accurate — do not support proposed policy changes.

The “evergreening” claim is that by securing additional patents and FDA-related exclusivities after approval of their new drugs, brand drug companies enjoy a period of exclusivity in the market that is longer than the …

Distorted Drug Patents, Erika Lietzan

Faculty Publications

Drug patents are distorted. Unlike most other inventors, drug inventors must complete years of testing to the government’s specifications and seek government approval to commercialize their inventions. All the while, the patent term runs. When a drug inventor finally launches a medicine that embodies the invention, only a fraction of the patent life remains. And yet, conventional wisdom holds — and empirical studies show — that patent life is essential to innovation in the pharmaceutical industry, perhaps more so than any other inventive industry. Congress tried to do something about this in 1984, authorizing the Patent and Trademark Office to …

The "Evergreening" Metaphor In Intellectual Property Scholarship, Erika Lietzan

Faculty Publications

This article is a plea for changes in the scholarly dialogue about "evergreening" by drug companies. Allegations that drug companies engage in "evergreening" are pervasive in legal scholarship, economic scholarship, medical and health policy scholarship, and policy writing, and they have prompted significant policymaking proposals. This Article was motivated by concern that the metaphor has not been fully explained and that policymaking in response might therefore be premature. It canvasses and assesses the scholarly literature-more than 300 articles discussing or mentioning "evergreening." It catalogues the definitions, the examples, and the empirical studies. Scholars use the term when describing certain actions …

Paper Promises For Drug Innovation, Erika Lietzan

Faculty Publications

Innovation does not stop when a new medicine is launched. Development of new uses for already approved drugs, in particular, can make profound contributions to the public health. Whether a new use is suspected during the initial premarket trials, identified through focused research after approval, or discovered serendipitously by physicians treating patients, however, it requires extensive clinical testing before it can be approved by FDA. This testing takes time and money — three to five years on average, and as much as $300 million. This Article considers the incentives that federal law offers to companies to make this investment: patent …

A Solution In Search Of A Problem At The Biologics Frontier, Erika Lietzan

Faculty Publications

This short paper comments on Professor Carrier's new article, Biologics: The New Antitrust Frontier. His article makes a profound initial contribution to a new area of scholarship, based on a large body of prior work considering antitrust issues relating to small molecule drugs. But Professor Carrier’s article, like my own forthcoming piece on innovation and competition in the biologics marketplace, is inherently speculative. We are making our best judgments about the nature of a still emerging marketplace and likely conduct in that marketplace, based on our understandings of a new regulatory framework that is itself still emerging, the broader legal …

The History And Political Economy Of The Hatch-Waxman Amendments, Erika Lietzan

Faculty Publications

Reform of the Hatch–Waxman generic drug framework is in the air. Scholars, consumer advocacy groups, regulated industry, and policymakers are engaged in heated debate about perceived shortcomings in the scheme, flaws, and unexpected loopholes. Changes in how the U.S. Food and Drug Administration (FDA) implements the law, as well as changes to the law itself, are under serious consideration. These policymaking discussions take place against a backdrop of shared assumptions about the origins and nature of the original Hatch–Waxman legislation — assumptions that this Article claims are wrong. Convention wisdom holds that the Hatch–Waxman legislation was a delicate compromise privately …

The Uncharted Waters Of Competition And Innovation In Biological Medicines, Erika Lietzan

Faculty Publications

In 2010, Congress fundamentally changed how federal law encourages the discovery and development of certain new medicines and for the first time authorized less expensive “duplicates” of these medicines to be approved and compete in the marketplace. The medicines at issue are biological medicines, generally made from, or grown in, living systems. Many of the world’s most important and most expensive medicines for serious and life–threatening diseases are biological medicines.

We have a profound interest in understanding and evaluating the impact of this legislation on innovation and competition. Scholars and courts considering this question may be tempted to reason from, …

The Law Of 180-Day Exclusivity, Erika Lietzan, Julia Post

Faculty Publications

In 1984, Congress created a statutory pathway for approval of generic drug applications and included an incentive for generic applicants to challenge the patents claiming the reference drugs on which they based their applications. The first generic applicant to file an ANDA with a patent challenge is eligible for 180 days of generic market exclusivity. This article is the fourth in a series of articles describing the resulting body of law, as interpreted and applied by FDA (in regulations, guidances, citizen petition responses, and individual decisions awarding and denying exclusivity) and the courts. The heart of the article is section …

The Myths Of Data Exclusivity, Erika Lietzan

Faculty Publications

This article contributes to an ongoing academic and public policy dialogue over whether and on what terms U.S. law should provide “data exclusivity” for new medicines. Five years after a new drug has been approved on the basis of an extensive application that may have cost more than one billion dollars to generate, federal law permits submission of a much smaller application to market a duplicate version of the drug. This second application is a different type of application, and it may cost no more than a few million dollars to prepare. A similar sequence is true for biological medicines: …

The History And Future Of E-Commerce Patents, Dennis D. Crouch, Mitchell L. Terry

Faculty Publications

The past two decades have seen a great rise in the patenting of e-commerce inventions. Now, those same patents are taking an equally great fall. In a series of four recent cases, the U.S. Supreme Court has shifted the doctrine of patent eligibility and, in the process, raised the bar for e-commerce and software patents - making it more difficult to obtain and enforce those types of patents.

The Standard For Awarding Attorney Fees Under 35 U.S.C. Section 285 To Prevailing Parties In Patent Litigation - Octane Fitness, Llc V. Icon Health & Fitness, Inc. And Highmark, Inc. V. Allcare Health Management Systems, Dennis D. Crouch, Jafon Fearson

Faculty Publications

The Supreme Court granted certiorari in two patent infringement cases that both concern shifting of attorney fees under the “exceptional case” standard of 35 U.S.C. § 285. The Federal Circuit has traditionally been resistant to fee shifting awards—especially in cases where an accused infringer is the prevailing party. In Octane Fitness, petitioner asks the Court to lower the standard for proving an exceptional case. In Highmark, petitioner asks for deference to lower court exceptional case findings.

A Trademark Justification For Design Patent Rights, Dennis D. Crouch

Faculty Publications

This article presents a new set of empirical results to support the theoretical construct that design patents fill a gap in trade dress law protection. Based on the data, I tentatively reject the oft-stated conventional wisdom that design patents are worthless for many because procurement is too slow, expensive, and difficult. Rather, based on a first-of-its-kind analysis of the prosecution history files of a large sample of recently issued design patents, I conclude that the current design patent examination system operates as a de facto registration system. Notably, more than ninety-eight percent (98%) of the patents in my study were …

An Empirical Study Of The Role Of The Written Description Requirement In Patent Prosecution, Dennis D. Crouch

Faculty Publications

An en banc Federal Circuit is now considering whether Section 112 of the Patent Act as properly interpreted includes a written description requirement that is separate and distinct from the enablement requirement. Although the USPTO has no direct role in the infringement dispute, the government submitted an amicus curie brief arguing that a separate written description requirement is “necessary to permit the USPTO to perform its basic examination function.” However, when pressed during oral arguments the government could not point to any direct evidence supporting its contention.

This essay presents the results of a retrospective empirical study of the role …

Nil: The Value Of Patents In A Major Crisis Such As An Influenza Pandemic, Dennis D. Crouch

Faculty Publications

This essay focuses on the role of patents in relation to a potential global crisis such as an influenza pandemic or other public health crisis. I argue that patent rights will be largely ignored during an epidemic and that any post-crisis compensation would likely be low when compared to traditional patent rewards or settlements entered under threat of injunctive relief. In some situations, such as use of a patented invention by a state or local government, a patentee may have no recourse. Part III of the essay raises a separate issue that stems from the relatively long time frame for …

2004 Update - 180-Day Exclusivity Under The Hatch-Waxman Amendments To The Federal Food, Drug, And Cosmetic Act, Erika Lietzan

Faculty Publications

This article updates the author's previously published article on the topic, provides some insight into recent events in this area of the law, and specifies a few minor items that were noted incorrectly in the earlier work.

What's New In Intellectual Property - Business Is Booming In Copyright, Trademark And Patent Law, Richard C. Reuben

Faculty Publications

Forget the trendy law practice areas of the 1980s, such as mergers and acquisitions, real estate and antitrust. Intellectual property is where the action will be in the 1990s.
