The "Broadest Reasonable Interpretation" And Applying Issue Preclusion To Administrative Patent Claim Construction, Jonathan I. Tietz
The "Broadest Reasonable Interpretation" And Applying Issue Preclusion To Administrative Patent Claim Construction, Jonathan I. Tietz
Michigan Law Review
Inventions are tangible. Yet patents comprise words, and words are imprecise. Thus, disputes over patents involve a process known as “claim construction,” which formally clarifies the meaning of a patent claim’s words and, therefore, the scope of the underlying property right. Adversarial claim construction commonly occurs in various Article III and Article I settings, such as district courts or the Patent Trial and Appeal Board (PTAB). When these proceedings ignore each other’s claim constructions, a patent’s scope can become inconsistent and unpredictable. The doctrine of issue preclusion could help with this problem. The Supreme Court recently reemphasized in B & …
Prometheus Rebound: Diagnostics, Nature, And Mathematical Algorithms, Rebecca S. Eisenberg
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 …
Wisdom Of The Ages Or Dead-Hand Control? Patentable Subject Matter For Diagnostic Methods After In Re Bilski, Rebecca S. Eisenberg
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 …
Pioneers Versus Improvers: Enabling Optimal Patent Claim Scope, Timothy Chen Saulsbury
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 …
Pharma's Nonobvious Problem, Rebecca S. Eisenberg
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 …
Obvious To Whom? Evaluating Inventions From The Perspective Of Phosita, Rebecca S. Eisenberg
Obvious To Whom? Evaluating Inventions From The Perspective Of Phosita, Rebecca S. Eisenberg
Articles
In this Article, I consider the possibility of giving the USPTO input from currently active technological practitioners in evaluating the obviousness of claimed inventions. Such input could potentially serve three useful functions. First, it could improve the accuracy of USPTO decisionmaking by providing access to the perspective of actual practitioners as to the obviousness of inventions from the perspective of the hypothetical PHOSITA. Second, it could help the USPTO document the evidentiary basis for rejections that rest in part upon tacit knowledge within technological communities. Third, it could provide a quality control mechanism that would improve the credibility of USPTO …

Patents - Option Of The Court To Permit Contempt Proceedings Or To Require A New Suit
Michigan Law Review
A final injunction was issued by the federal district court of Massachusetts against A, a Michigan corporation. The terms of the injunction were that A should not make, use, or sell lasts, or any colorable imitation thereof, embodying the invention covered by certain enumerated claims belonging to the present complainant. In a subsequent term of court the complainant alleged a violation of the injunction and brought contempt proceedings against A in the district court. The alleged infringement consisted in the manufacture and sale of a device which was slightly changed in form from that which the defendant had made prior …
Patent Law: Secret Use As Affecting Right To A Patent, John B. Waite
Patent Law: Secret Use As Affecting Right To A Patent, John B. Waite
Articles
An unusually obvious piece of judicial legislation, of practical importance to the manufacturing world, was promulgated in the case of Macbeth-Evans Glass Co. v. General Electric Co., 246 Fed. 695. The facts were that in 1903 Macbeth had invented a process for making glass. Since that time the plaintiff company, of which Macbeth was president, had been using that process. This use had, however, been "secret". In 1910 an employee of the plaintiff revealed the process to the Jefferson Glass Co., which at once began to use it, but on application of the Macbeth Co. the state court enjoined the …
