Teva And The Process Of Claim Construction, Lee Petherbridge Ph.D., R. Polk Wagner Jan 2018

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 …


Life After Bilski, Mark A. Lemley, Michael Risch, Ted Sichelman, R. Polk Wagner Jan 2011

Life After Bilski, Mark A. Lemley, Michael Risch, Ted Sichelman, R. Polk Wagner

All Faculty Scholarship

In Bilski v. Kappos, the Supreme Court declined calls to categorically exclude business methods—or any technology—from the patent law. It also rejected as the sole test of subject matter eligibility the Federal Circuit’s deeply-flawed machine-or-transformation test, under which no process is patentable unless it is tied to a particular machine or transforms an article to another state or thing. Subsequent developments threaten to undo that holding, however. Relying on the Court’s description of the Federal Circuit test as a “useful and important clue,” the U.S. Patent and Trademark Office, patent litigants, and district courts have all continued to rely on …


The Federal Circuit And Patentability: An Empirical Assessment Of The Law Of Obviousness, Lee Petherbridge, R. Polk Wagner Jan 2007

The Federal Circuit And Patentability: An Empirical Assessment Of The Law Of Obviousness, Lee Petherbridge, R. Polk Wagner

All Faculty Scholarship

It is by now a cliché to suggest that the United States Court of Appeals for the Federal Circuit has weakened the standards for obtaining patents. In this article, we empirically assess that Court’s performance on the ultimate question of patentability— the requirement that a patentable invention must be “nonobvious.” Our findings suggest that the conventional wisdom may not be well-grounded, at least on this measure. Nowhere is the Federal Circuit’s controversial role as the locus of judicial power in the U.S. patent system more evident than in the context of the doctrine of obviousness under 35 U.S.C. § 103. …


Is The Federal Circuit Succeeding? An Empirical Assessment Of Judicial Performance, Polk Wagner, Lee Petherbridge Mar 2004

Is The Federal Circuit Succeeding? An Empirical Assessment Of Judicial Performance, Polk Wagner, Lee Petherbridge

All Faculty Scholarship

As an appellate body jurisdictionally demarcated by subject matter rather than geography, the United States Court of Appeals for the Federal Circuit occupies a unique role in the federal judiciary. This controversial institutional design has had profound effects on the jurisprudential development of the legal regimes within its purview - especially the patent law, which the Federal Circuit has come to thoroughly dominate in its two decades of existence. In this Article, we assess the court's performance against its basic premise: that, as compared to prior regional circuit involvement, centralization of legal authority will yield a clearer, more coherent, and …


Of Patents And Path Dependency: A Comment On Burk And Lemley, R. Polk Wagner Jan 2004

Of Patents And Path Dependency: A Comment On Burk And Lemley, R. Polk Wagner

All Faculty Scholarship

This Article delves into issues surrounding the relationship between technology and the patent law. Responding to Dan Burk and Mark Lemley's earlier article, Is Patent Law Technology-Specific?, the piece notes that the basic question posed by Burk and Lemley's article is a relatively easy question given the several doctrines that explicitly link the subject matter context of an invention to the validity and scope of related patents. This sort of technological exceptionalism (which this Article refers to as micro-exceptionalism) is both observable and easily justifiable for a legal regime directed to technology policy. In contrast, Burk and Lemley's identification of, …


Reconsidering Estoppel: Patent Administration And The Failure Of Festo, R. Polk Wagner Jan 2002

Reconsidering Estoppel: Patent Administration And The Failure Of Festo, R. Polk Wagner

All Faculty Scholarship

Last Term, in Festo Corporation v. Shoketsu Kinzoku Kogyo Kabashuki Co., the United States Supreme Court missed perhaps the most important opportunity for patent law reform in two decades. At the core of the failure to grasp the implications of "prosecution history estoppel" - a judicially-crafted principle limiting the enforceable scope of patents based on acts occurring during their application process - is the heretofore universal (but ultimately unsupportable) view of the doctrine as an arbitrary ex post limitation on patent scope. This Article demonstrates the serious flaws in this traditionalist approach, and develops a new theory of prosecution history …
