The Supreme Court‟s recent opinion in Bilski v. Kappos2 is the most recent example. There, the Court struggled to determine whether a patent eligible “process” under 35 U.S.C. §1013 encompasses methods of doing business. The controversy was not so much that “process” was insolubly ambiguous, because all nine Justices agreed that the generally accepted definition of process is incredibly broad. Instead, the court considered whether courts should reign in this breadth to exclude business methods. Four concurring justices would have banned business methods outright as a matter of history and policy. The majority ruled that business methods might be a patentable “process,” but that Bilski‟s method was too abstract. The irony is that the majority purported to strictly apply the statutory language even though no abstractness exception appears in the statute. The Bilski Court leaves many doctrinal questions, such as how one should determine when a method is too abstract, and whether there should be other (or any) unwritten patent eligibility exceptions. One patent examiner memorably describes the uncertainty: “I'll tell you what, I wish I could write 101 rejections with as little supporting analysis as the Supreme Court did in the Bilski decision. A little discussion of precedential caselaw[], some hand-waving, and the conclusion that the claims at issue are drawn to an abstract idea.”4 * ©2010 Michael Risch, Associate Professor of Law, Villanova University School of Law.

Valuable research assistance was provided by Thomas Huycke and Jenny Maxey. 1 35 U.S.C. §101 (2000) (“Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor…”). 2 561 U.S. __ (2010). 3 Supra, note 1. 4 Bilski Fallout, http://just-n-examiner.livejournal.com/44111.html (June 30, 2010). The quote continues: “Actually, it didn't even seem like a conclusion, it very much seemed as if the decision that the claims were drawn to an abstract idea was the starting point of the 27-Jul-10] New Uses for Patent Utility 2 There are many principled ways to make headway through doctrinal thickets like that presented by Bilski. Some look to economic analysis, others to natural rights, while still others focus primarily on patentability criteria such as newness and disclosure. One helpful overarching principle that has escaped attention is utility – the usefulness of the invention. This article shows how usefulness can provide a principled approach to resolve longstanding policy-based doctrinal questions, resolve close questions of patentability, explain existing rules, or provide meaning to vague requirements. To be sure, usefulness does not answer every question, and in some cases can only provide guidance rather than resolution. Even so, this article presents the first comprehensive illustration of how difficult, fundamental questions become answerable when viewed through the lens of usefulness. Usefulness and the traditional patent utility requirement are technically distinct. Usefulness refers generally to an invention‟s benefits, which might vary by type, quantity, or timing. Usefulness can mean many things, such as how an invention operates, the practical benefits it provides to the public, or its effect on commercial markets such as the supply or demand for a particular product. A subset of usefulness is the traditional patent utility requirement: because patents must be “new and useful,” they must show some usefulness. This article calls the traditional utility requirement “eligibility- usefulness.” The level of eligibility-usefulness currently required is extremely low – the invention need only operate as described and potentially provide some de minimis public benefit. Courts and commentators frequently call eligibility-usefulness “utility” as shorthand. Because this article examines usefulness for more than just eligibility, the term “utility” is treated throughout as meaning usefulness generally, and not just traditional eligibility-usefulness. This article introduces “input-usefulness,” as opposed to “eligibility- usefulness.” Input-usefulness more generally considers all types of an invention‟s benefits, as well as the amount and timing of those benefits. The way that input-usefulness informs patent policy may be quite different than traditional minimal eligibility-usefulness requirement. Eligibility-usefulness considers only two types of usefulness, only at the time of invention, and never by amount. Input-usefulness is unbounded, allowing for a more generalized consideration of an invention‟s benefits. For example, input-usefulness could help lower courts determine whether a claim is abstract as required by Bilski. In Bilski, the representative claim involved the steps of initiating commodities transactions at one price, Court's deliberations. What that means, unfortunately, is that there was no analysis of how they reached that conclusion, and I really would like to have seen that type of analysis.”). 27-Jul-10] New Uses for Patent Utility 3 identifying others who might transact at a different price, and initiating transactions at that price. This, the Supreme Court ruled, was the abstract idea of hedging and thus unpatentable. Principled support for the Court‟s finding, however, is not so clear. The term abstract means generalized as opposed to concrete and specific.5 But Bilski‟s method for trading in commodities requires three specific and concrete steps. It is certainly no less specific and concrete than a general method for making alcohol by mixing molasses and water,6

    OVERVIEW OF AN INFRINGEMENT ANALYSIS FOR U.S. UTILITY PATENT By John C. Garvey The following is a summary of the basic issues which the U. S. Supreme Court and the Court of Appeals for the Federal Circuit (“Federal Circuit”) indicate should be considered by anyone performing an infringement analysis. The issues are discussed in the order presented on the attached Infringement Analysis Diagram. This is not meant to indicate that the issues must be considered in this order, or that all issues are pertinent to every infringement analysis. For example, decisions written by the courts tend to focus on only those issues which are relevant to the facts of the case being decided. However, anyone performing an infringement analysis should at least consider whether each of these issues is pertinent to the facts of the situation being analyzed. CLAIM CONSTRUCTION The first step in any infringement analysis is to interpret or construe the claim language. The focus in construing a claim term is on what one of ordinary skill in the art at the time of the invention, would have understood the term to mean. Markman v. Westview Instruments, Inc., 52 F.3d 967, 34 USPQ2d 1321, 1335 (Fed. Cir. 1995) (en banc), affirmed 116 SCt 1384, 38 USPQ 2d 1461 (1996). Three sources are used to construe the meaning of claims: the claims, the specification, and the prosecution history. Markman, 34 USPQ2d at 1329. While extrinsic evidence such as expert testimony may be used to assist a court in construing the claims, such extrinsic evidence cannot be used to vary or contradict the terms of the claims as explained in the patent or prosecution history.

    Advance Copy EVIDENCE OF ‘EVERGREENING’ IN SECONDARY PATENTING OF BLOCKBUSTER DRUGS ANDREW F CHRISTIE, * CHRIS DENT† AND DAVID M STUDDERT‡ Secondary patents associated with blockbuster drugs are granted for follow-on innova- tions relating to the active pharmaceutical ingredient (‘API’) of the drug. Our analysis of all secondary patents for 13 top-selling drugs in Australia shows that, while the majority of follow-on innovations are made by entities other than the originator of the drug, the innovations with the highest private value are undertaken by the drug’s originator and concern a delivery mechanism or an alternative formulation for the API. Since that is the type of follow-on innovation most commonly undertaken by drug originators, and considered most likely to result in a de facto extension of marketplace monopoly over the drug, we see in these findings evidence that the originators of blockbuster drugs engage in secondary patenting that has an ‘evergreening’ effect.

  • Remedies for Patent Infringement
    Remedies for Patent Infringement John R. Thomas Visiting Scholar July 18, 2017 Congressional Research Service 7-5700 www.crs.gov R44904 Remedies for Patent Infringement Summary For more than a decade, some Members of Congress have considered bills that have proposed reforms to the law of patent remedies. Under current law, courts may award damages to compensate patent proprietors for an act of infringement. Damages consist of the patent owner’s lost profits due to the infringement, if they can be proven. Otherwise the adjudicated infringer must pay a reasonable royalty. Courts may also award enhanced damages of up to three times the actual damages in exceptional cases. In addition, courts may issue an injunction that prevents the adjudicated infringer from employing the patented invention until the date the patent expires. Finally, although usually each litigant pays its own attorney fees in patent infringement cases, win or lose, the courts are authorized to award attorney fees to the prevailing party in exceptional cases. Some observers believe that the courts are adequately assessing remedies against adjudicated patent infringers. Others have expressed concerns that the current damages system systematically overcompensates patent proprietors. Some suggest that the usual rule regarding attorney fees— under which each side most often pays its own fees—may encourage aggressive enforcement tactics by “patent assertion entities,” which are sometimes pejoratively called patent trolls. Damages often occur in the context of a patent that covers a single feature of a multi-component product. In addition, many of these other components are subject to additional patents with a fragmented ownership.

  • Patent-Eligible Subject Matter Under 35 U.S.C. § 101
    Patent-Eligible Subject Matter Under 35 U.S.C. § 101 Adopted by the IEEE-USA Board of Directors (22 Oct. 2019) IEEE-USA supports a patent system that protects and preserves innovations in all technology sectors--including software, computer-implemented systems, medical devices, diagnostic, treatment, dosing methods, pharmaceuticals, manmade materials, and isolated or improved versions of materials that exist in nature only in impure form. Decisions on subject matter eligible for patent protection --the kind and type of inventions to be so protected – should be made under predictable rules. Categories of subject matter eligible for protection under U.S. patent laws, stated in 35 U.S.C. §101 (“any … process, machine, manufacture, or composition of matter, or any … improvement thereof”), should be broad enough to include all innovations that include technological content. The “subject matter” requirement of §101 is a gating filter that excludes from the patent system such areas as the fine arts, social sciences, unembodied abstract ideas, laws of pure science with no application, and the like. Patent-eligible subject matter is only one requirement among many in the patent system. Subject matter eligibility inquiries should not be conflated with, confused, or diluted by concerns for prior art, obviousness, quality of disclosure, or definiteness of claiming. Patent protection is an essential property interest for entrepreneurs and inventors. Patent protection serves to help attract investment. Investment is essential; and often, it is the most constrained input, in the process of turning ideas into products and businesses. A strong patent system provides individuals, startups, small companies, and large companies alike with a sustainable competitive advantage.
