Decisionmaking In Patent Cases At The Federal Circuit, Jason Reinecke

Washington and Lee Law Review

This Article provides the results of an empirical study assessing the impact of panel composition in patent cases at the Federal Circuit. The dataset includes 2675 three-judge panel-level final written decisions and Rule 36 summary affirmances issued by the Federal Circuit between January 1, 2014 and May 31, 2021. The study informs the longstanding debate concerning whether the Federal Circuit is succeeding as a court with nationwide jurisdiction in patent cases and provides insight into judicial decisionmaking more broadly. And several results show that many of the worst fears that commentators have about the Federal Circuit appear overstated or untrue. …

A Functional Approach To Judicial Review Of Ptab Rulings On Mixed Questions Of Law And Fact, Rebecca S. Eisenberg

Articles

The Court of Appeals for the Federal Circuit (“Federal Circuit”) has long relied on active appellate review to bring uniformity and clarity to patent law. It initially treated the PTO the same as the federal district courts, reviewing its factual findings for clear error and its legal conclusions de novo. Following reversal by the Supreme Court in Dickinson v. Zurko, the Federal Circuit began giving greater deference to PTO factual findings. But it continued to review the PTO’s legal conclusions de novo, while coding an expansive list of disputed issues in patent cases as legal conclusions, even when they …

The Federal Circuit As An Institution, Ryan G. Vacca

Law Faculty Scholarship

The Court of Appeals for the Federal Circuit is a unique institution. Unlike other circuit courts, the Federal Circuit’s jurisdiction is bound by subject area rather than geography, and it was created to address a unique set of problems specific to patent law. These characteristics have affected its institutional development and made the court one of the most frequently studied appellate courts. This chapter examines this development and describes the evolving qualities that have helped the Federal Circuit distinguish itself, for better or worse, as an institution.

This chapter begins with an overview of the concerns existing before creation of …

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 …

Teva And The Process Of Claim Construction, Lee Petherbridge Ph.D., R. Polk Wagner

All Faculty Scholarship

In Teva Pharmaceuticals USA, Inc. v. Sandoz, Inc., the Supreme Court addressed an oft-discussed jurisprudential disconnect between itself and the U.S. Court of Appeals for the Federal Circuit: whether patent claim construction was “legal” or “factual” in nature, and how much deference is due to district court decisionmaking in this area. In this Article, we closely examine the Teva opinion and situate it within modern claim construction jurisprudence. Our thesis is that the Teva holding is likely to have only very modest effects on the incidence of deference to district court claim construction but that for unexpected reasons the …

How Much Has The Supreme Court Changed Patent Law?, Paul Gugliuzza

Faculty Scholarship

The U.S. Supreme Court has decided a remarkable number of patent cases in the past decade, particularly as compared to the first twenty years of the Federal Circuit’s existence. No longer is the Federal Circuit “the de facto Supreme Court of patents,” as Mark Janis wrote in 2001. Rather, it seems the Supreme Court is the Supreme Court of patents. In the article at the center of this symposium, Judge Timothy Dyk of the Federal Circuit writes that the Supreme Court’s decisions “have had a major impact on patent law,” citing, among other evidence, the Court’s seventy percent reversal rate …

Regulating Patent Assertions, Paul Gugliuzza

Faculty Scholarship

Recent years have seen a proliferation of statutes regulating and lawsuits challenging patent enforcement conduct. The Federal Circuit, however, has held that acts of patent enforcement are illegal only if there is clear and convincing evidence both that the patent holder’s infringement allegations were objectively baseless and that the patent holder knew or should have known its allegations were baseless. This chapter summarizes recent efforts by state governments and the federal government to control patent enforcement behavior, questions the broad immunity the Federal Circuit has conferred on patent holders, and seeks to improve pending federal legislation governing patent enforcement. In …

The Supreme Assimilation Of Patent Law, Peter Lee

Michigan Law Review

Although tensions between universality and exceptionalism apply throughout law, they are particularly pronounced in patent law, a field that deals with highly technical subject matter. This Article explores these tensions by investigating an underappreciated descriptive theory of Supreme Court patent jurisprudence. Significantly extending previous scholarship, it argues that the Court’s recent decisions reflect a project of eliminating “patent exceptionalism” and assimilating patent doctrine to general legal principles (or, more precisely, to what the Court frames as general legal principles). Among other motivations, this trend responds to rather exceptional patent doctrine emanating from the Federal Circuit in areas as varied as …

Diagnostics Need Not Apply, Rebecca S. Eisenberg

Articles

Diagnostic testing helps caregivers and patients understand a patient's condition, predict future outcomes, select appropriate treatments, and determine whether treatment is working. Improvements in diagnostic testing are essential to bringing about the long-heralded promise of personalized medicine. Yet it seems increasingly clear that most important advances in this type of medical technology lie outside the boundaries of patent-eligible subject matter. The clarity of this conclusion has been obscured by ambiguity in the recent decisions of the Supreme Court concerning patent eligibility. Since its 2010 decision in Bilski v. Kappos, the Court has followed a discipline of limiting judicial exclusions from …

E-Obviousness, Glynn S. Lunney Jr.

Glynn Lunney

As patents expand into e-commerce and methods of doing business more generally, both the uncertainty and the risk of unjustified market power that the present approach generates suggest a need to rethink our approach to nonobviousness. If courts fail to enforce the nonobviousness requirement and allow an individual to obtain a patent for simply implementing existing methods of doing business through a computer, even where only trivial technical difficulties are presented, entire e-markets might be handed over to patent holders with no concomitant public benefit. If courts attempt to enforce the nonobviousness requirement, but leave undefined the extent of the …

Patent Dialogue, Jonas Anderson

Articles in Law Reviews & Other Academic Journals

This Article examines the unique dialogic relationship that exists between the Supreme Court and Congress concerning patent law. In most areas of the law, Congress and the Supreme Court engage directly with each other to craft legal rules. When it comes to patent law, however, Congress and the Court often interact via an intermediary institution: the U.S. Court of Appeals for the Federal Circuit. In patent law, dialogue often begins when Congress or the Supreme Court acts as a dialogic catalyst, signaling reform priorities to which the Federal Circuit often responds.

Appreciating the unique nature of patent dialogue has important …

Congress As A Catalyst Of Patent Reform At The Federal Circuit, Jonas Anderson

Articles in Law Reviews & Other Academic Journals

The U.S. Court of Appeals for the Federal Circuit is the dominant institution in patent law. The court’s control over patent law and policy has led to a host of academic proposals to shift power away from the court and towards other institutions, including the U.S. Supreme Court, the U.S. Patent and Trademark Office, and federal district courts. Surprisingly, however, academics have largely dismissed Congress as a potential institutional check on the Federal Circuit. Congress, it is felt, is too slow, too divided, and too beholden to special interests to effectively monitor changes in innovation and respond with appropriate reforms. …

Saving The Federal Circuit, Paul Gugliuzza

Faculty Scholarship

In a recent, attention-grabbing speech, the Chief Judge of the Seventh Circuit, Diane Wood, argued that Congress should abolish the Federal Circuit’s exclusive jurisdiction over patent cases. Exclusive jurisdiction, she said, provides too much legal uniformity, which harms the patent system. In this response to Judge Wood’s thoughtful speech, I seek to highlight two important premises underlying her argument, neither of which is indisputably true.

The first premise is that the Federal Circuit actually provides legal uniformity. Judge Wood suggests that, due to the Federal Circuit’s exclusive jurisdiction, patent doctrine is insufficiently “percolated,” meaning that it lacks mechanisms through which …

The Federal Circuit As A Federal Court, Paul Gugliuzza

Faculty Scholarship

The U.S. Court of Appeals for the Federal Circuit has exclusive jurisdiction over patent appeals and, as a consequence, the last word on many legal issues important to innovation policy. This Article shows how the Federal Circuit augments its already significant power by impeding other government institutions from influencing the patent system. Specifically, the Federal Circuit has shaped patent-law doctrine, along with rules of jurisdiction, procedure, and administrative law, to preserve and expand the court’s power in four interinstitutional relationships: the court’s federalism relationship with state courts, its separation of powers relationship with the executive and legislative branches, its vertical …

Hyperactive Judges: An Empirical Study Of Judge-Dependent "Judicial Hyperactivity" In The Federal Circuit, Ted L. Field

Ted L. Field

This article presents an empirical study of the extent to which individual judges of the U.S. Court of Appeals for the Federal Circuit—which has exclusive jurisdiction over patent appeals—engage in what William C. Rooklidge and Matthew F. Weil call “judicial hyperactivity.” This article defines “judicial hyperactivity” as a form of judicial activism in which a judge improperly “elevate[s] his or her judgment above that of another constitutionally significant actor (e.g., Congress, the President, [or] other Article III courts),” where this improper behavior is not necessarily driven by politics or ideology as is traditional judicial activism. This study considers the extent …

Prometheus Rebound: Diagnostics, Nature, And Mathematical Algorithms, Rebecca S. Eisenberg

Articles

The Supreme Court’s decision last Term in Mayo v. Prometheus left considerable uncertainty as to the boundaries of patentable subject matter for molecular diagnostic inventions. First, the Court took an expansive approach to what counts as an unpatentable natural law by applying that term to the relationship set forth in the challenged patent between a patient’s levels of a drug metabolite and the indication of a need to adjust the patient’s drug dosage. And second, in evaluating whether the patent claims add enough to this unpatentable natural law to be patent eligible, the Court did not consult precedents concerning the …

Rethinking Federal Circuit Jurisdiction, Paul Gugliuzza

Faculty Scholarship

Thirty years ago, Congress created the Federal Circuit for the overriding purpose of bringing uniformity to patent law. Yet less than half of the court’s cases are patent cases. Most Federal Circuit cases involve veterans benefits, government-employment actions, government contracts, and other matters. Although existing literature purports to study the Federal Circuit as an institution, these projects focus largely on the court’s patent cases. This Article, by contrast, considers whether the court’s nonpatent docket might affect the development of patent law and whether the court’s specialization in patent law has consequences for how it decides nonpatent cases.

These inquiries result …

An Explicit Policy Lever For Patent Scope, Anna B. Laakmann

Michigan Telecommunications & Technology Law Review

Since its inception in 1982, the Federal Circuit has declined to take an overt role in setting patent policy. Dan Burk and Mark Lemley have observed that the court instead implicitly engineers patent policy through selective application of its patentability rules, which operate as "policy levers." Recent decisions on the patentability of diagnostic and therapeutic methods illustrate a significant problem with this approach. By maintaining a façade of adjudicative rule formalism while tacitly manipulating its rules to approximate policy goals, the court perpetuates empirical uncertainty about the patent law's practical effects. This Article proposes that the Federal Circuit use the …

Pluralism On Appeal, Paul Gugliuzza

Faculty Scholarship

In a thoughtful response to my article, Rethinking Federal Circuit Jurisdiction, Ori Aronson notes that judges “work in context, be it social, cultural, or...institutional,” and that “context matters” to their decisions. Indeed, the primary aim of my article was to spur a conversation about the context in which the judges of the Federal Circuit — who have near plenary control over U.S. patent law — decide cases. That context includes many matters in narrow areas of law that bear little relation to the innovation and economic concerns that should animate patent law. To inject those concerns into the court’s province, …

The New Federal Circuit Mandamus, Paul Gugliuzza

Faculty Scholarship

This Article explores an ongoing revolution in the mandamus jurisprudence of the U.S. Court of Appeals for the Federal Circuit, the court of appeals with nearly exclusive jurisdiction over patent cases. Before December 2008, the Federal Circuit had never used the interlocutory writ of mandamus to order a district court to transfer a case to a more convenient forum, denying each one of the twenty-two petitions it had decided on that issue. Since that time, however, the court has overturned eleven different venue decisions on mandamus. Remarkably, ten of those eleven cases have come from the same district court, the …

Wisdom Of The Ages Or Dead-Hand Control? Patentable Subject Matter For Diagnostic Methods After In Re Bilski, Rebecca S. Eisenberg

Articles

In 1980, the Supreme Court gave a reassuring signal to the then-nascent biotechnology industry about the availability of patent protection for the fruits of its research when it upheld the patentability of a genetically modified living organism in Diamond v. Chakrabarty. Twenty-five years later, the Court seemed poised to reexamine the limits of patentable subject matter for advances in the life sciences when it granted certiorari in Laboratory Corporation v. Metabolite. But the Federal Circuit had not addressed the patentable subject matter issue in Laboratory Corporation, and the Court ultimately dismissed the certiorari p etition as improvidently granted. Five years …

Not So Technical: An Analysis Of Federal Circuit Patent Decisions Appealed From The Itc, Holly Lance

Michigan Telecommunications & Technology Law Review

A widespread perception among the patent law community is that the patent system would be more effective if judges with technical backgrounds and patent law experience decided patent disputes. Proponents believe that if judges all had similar baseline knowledge of technological analysis, there would be more consistency in decision-making, leading to more predictability for parties. Some district courts have unofficially become semi-specialized in patent law disputes, and Congress is debating whether to institute a more formalized Patent Pilot Program in which district court judges specialize in patent law cases. This Note joins the debate and examines patent law cases at …

Pioneers Versus Improvers: Enabling Optimal Patent Claim Scope, Timothy Chen Saulsbury

Michigan Telecommunications & Technology Law Review

Arising most commonly as a defense to an infringement claim, enablement requires a patent to describe the claimed invention in sufficient detail to permit a person having ordinary skill in the relevant field to replicate and use the invention without needing to engage in "undue experimentation." If a patent claim is not "enabled"--i.e., if a person having ordinary skill in the art (PHOSITA) who studied the patent cannot make or use the invention without undue experimentation--the claim is invalid and can no longer be asserted. This penalty deters patent applicants from claiming more than they invented and allows others to …

Appellate Review Of Patent Claim Construction: Should The Federal Circuit Be Its Own Lexicographer In Matters Related To The Seventh Amendment, Eileen M. Herlihy

Michigan Telecommunications & Technology Law Review

The Federal Circuit stated in an en banc decision in Cybor Corp. v. FAS Technologies, Inc. that the construction of patent claims is "a purely legal issue," and is therefore subject to de novo review on appeal. The Cybor decision reaffirmed the position of the majority of the Federal Circuit which had been announced in its en banc Markman decision, and proclaimed that the de novo standard of review is supported by the Supreme Court's Markman decision, a Seventh Amendment opinion. However, Cybor included strong opposition to a de novo standard of review from some of the judges of the …

Practice Makes Perfect? An Empirical Study Of Claim Construction Reversal Rates In Patent Cases, David L. Schwartz

Michigan Law Review

This Article examines whether U.S. district court judges improve their skills at patent claim construction with experience, including the experience of having their own cases reviewed by the Court of Appeals for the Federal Circuit. In theory, higher courts teach doctrine to lower courts via judicial decisions, and lower courts learn from these decisions. This Article tests the teaching-and-learning premise on the issue of claim construction in the realities of patent litigation. While others have shown that the Federal Circuit reverses a large percentage of lower court claim constructions, no one has analyzed whether judges with more claim construction appeal …

The Claim Construction Effect, Lee Petherbridge

Michigan Telecommunications & Technology Law Review

Claim construction refers to the task of construing, or interpreting, the words of patents' claims to establish the metes and bounds of a patent. Theoretically, the task of claim construction serves to operationalize the concept of "invention," which lies at the heart of the U.S. patent system.[...] Rather than focusing on the set of cases in which the Federal Circuit addresses claim construction, this study focuses on a set of cases defined by a different patent doctrine. The basic idea is to explore the impact of claim construction on other areas of patent law.[...] The hypothesis of the claim construction …

Pharma's Nonobvious Problem, Rebecca S. Eisenberg

Articles

This Article considers the effect of the recent decision of the U.S. Supreme Court in KSR International Co. v. Teleflex, Inc. on the nonobviousness standard for patentability as applied to pharmaceutical patents. By calling for an expansive and flexible analysis and disapproving of the use of rigid formulas in evaluating an invention for obviousness, KSR may appear to make it easier for generic competitors to challenge the validity of drug patents. But an examination of the Federal Circuit's nonobviousness jurisprudence in the context of such challenges reveals that the Federal Circuit has been employing all along the sort of flexible …

Exclusion Confusion? A Defense Of The Federal Circuit's Specific Exclusion Jurisprudence, Peter Curtis Magic

Michigan Law Review

Specific exclusion has become a controversial limitation on the doctrine of equivalents, which is itself an essential and controversial area of patent law. The doctrine of equivalents allows a patentee to successfully claim infringement against devices that are outside of the literal reach of the language used by the patentee in her patent to describe what she claims as her invention. The Supreme Court has prescribed some of the outer limits of the doctrine of equivalents and articulated the underlying policy concerns that inform its analysis-noting that courts should balance protection of the patentee's intellectual property with the public's reasonable …
