An Explicit Policy Lever For Patent Scope, Anna B. Laakmann Jan 2012

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 …


Not So Technical: An Analysis Of Federal Circuit Patent Decisions Appealed From The Itc, Holly Lance Jan 2010

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 Jan 2010

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 Jan 2009

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 …


The Claim Construction Effect, Lee Petherbridge Jan 2008

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 …


Restoring The Genetic Commons: A Common Sense Approach To Biotechnology Patents In The Wake Of Ksr V. Teleflex , Anna Bartow Laakmann Jan 2007

Restoring The Genetic Commons: A Common Sense Approach To Biotechnology Patents In The Wake Of Ksr V. Teleflex , Anna Bartow Laakmann

Michigan Telecommunications & Technology Law Review

In this Article, I argue that a new approach to biotechnology patenting is necessary to fully realize the tremendous potential of recent advances in our understanding of the human genome. Part I places the gene patenting debate in context by highlighting the key landmarks that have shaped the biotechnology industry and outlining the products and stakeholders that comprise the industry. Part II describes the current state of the law on biotechnology patents, summarizing the Federal Circuit's application of the various doctrines that collectively define the patent landscape's parameters. In this Part, I explain how the Federal Circuit's jurisprudence is tied …


Patent Injunctions And The Problem Of Uniformity Cost, Michael W. Carroll Jan 2007

Patent Injunctions And The Problem Of Uniformity Cost, Michael W. Carroll

Michigan Telecommunications & Technology Law Review

In eBay v. MercExchange, the Supreme Court correctly rejected the Federal Circuit's general rule requiring that a permanent injunction follow from a finding that a patent is valid and infringed. Recognizing that one size does not fit all in patent law, the Court returned traditional equitable discretion to the district courts. With this discretion, district courts can now deploy remedies for patent infringement that are sensitive to relevant differences among industries, technologies, and entities. This Essay sets the Court's rejection of a uniform remedial regime in a larger context concerning the role of uniformity in patent law. It then explores …


The Experimental Purpose Doctrine And Biomedical Research, Tao Huang Oct 2004

The Experimental Purpose Doctrine And Biomedical Research, Tao Huang

Michigan Telecommunications & Technology Law Review

The experimental use doctrine is a common law rule in patent law that until a few years ago excused accused infringers who made and used patented products or processes on the basis of an experimental, educational, or nonprofit purpose when there was de minimis economic injury to the patent owner and de minimis economic gain to the infringer. While the application of the experimental purpose doctrine was always narrow, two recent Federal Circuit decisions indicate that there is not much left under its aegis. In Madey v. Duke University, the Federal Circuit strictly limited the application of the experimental purpose …


Arising Under Jurisdiction And Uniformity In Patent Law, Christopher A. Cotropia Apr 2003

Arising Under Jurisdiction And Uniformity In Patent Law, Christopher A. Cotropia

Michigan Telecommunications & Technology Law Review

The law governing the Federal Circuit's appellate jurisdiction was brought into question in Holmes Group, Inc. v. Vornado Circulation Systems, Inc. The Federal Circuit's appellate jurisdiction over Vornado's appeal rested solely on Vornado's counterclaim alleging patent infringement by Holmes. Holmes's complaint sought a declaratory judgment of no trade dress infringement and did not include any patent law claims. While the Federal Circuit found appellate jurisdiction over Vornado's appeal based on the counterclaim of patent infringement, the Supreme Court disagreed. The Court focused on the language in 35 U.S.C. § 1338(a), which defines the Federal Circuit's appellate jurisdiction by the statute's …


Business Method Patents And Their Limits: Justifications, History, And The Emergence Of A Claim Construction Jurisprudence, Nicholas A. Smith Oct 2002

Business Method Patents And Their Limits: Justifications, History, And The Emergence Of A Claim Construction Jurisprudence, Nicholas A. Smith

Michigan Telecommunications & Technology Law Review

Scholars, practitioners, and even popular media spilled much ink over business method patents in the late 1990s, eager to discuss the shift in jurisprudence that enabled patent holders to enforce business method patents for the first time. Since that initial period of excitement--during which businesses filed record numbers of applications for business method patents, and numerous articles tracing the doctrinal shift were published--commentators have written little on the topic. Various patent holders, however, have since litigated business method patent claims. During these first few years after judicial endorsement of business method patents, such litigation has focused on the scope of …


E-Obviousness, Glynn S. Lunney Jr. Jan 2001

E-Obviousness, Glynn S. Lunney Jr.

Michigan Telecommunications & Technology Law Review

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 …


Escaping The World Of I Know It When I See It: A New Test For Software Patent Ability, Brooke Schumm Iii Jun 1996

Escaping The World Of I Know It When I See It: A New Test For Software Patent Ability, Brooke Schumm Iii

Michigan Telecommunications & Technology Law Review

The major thesis presented in this article is a focused standard of software patentability, in particular for pure computational methods or algorithms directed to the manipulation of numbers operating on a computer. The general philosophy is to compel inventors to narrow their claims to an algorithm expressed in terms of its utility and then to require that the particular utility or functionality be expressed in the claim as a limit on the claim, thus precluding the patent monopoly from being overbroad. As a corollary, any person is free to use or perhaps to patent the algorithm for a different utility …
