Are Means-Plus-Function Claims Reasonably Certain to Require Tables of Support?

David Orange

The most likely victims of the Supreme Court’s Nautilus v. Biosig decision appear unaware of their fate. When the Court explained that patent claims must be more than merely “amenable to construction,” but rather must provide “reasonable certainty” in order to meet the requirements of the second section of 35 U.S.C. §112, it is actually claims invoking the sixth section of this statute, better known as means-plus-function claims, that could be invalidated first. Means-plus-function claims are at risk for exactly the reasons that attorneys include them: there is flexibility in matching the claim element to examples from the patent. The flexibility of means-plus-function claims is now on a collision course with the new reasonable certainty standard. Patent drafters seeking the protection of old means-plus-function standards may be creating the very “zone of uncertainty” that Nautilus prohibits. Without new case law, practitioners may not understand how to draft valid means-plus-function claims going forward. This paper considers both legal and practical considerations to forecast how the Patent Trial and Appeal Board will guide applicants.

Patentee's Monetary Recovery From An Infringer - A Revisit

Richard L. Stroup, Cecilia Sanabria, Kelly C. Lu, & Daniel G. Chung

In 1977, the original article was published in this Journal, authored by a younger version of one of the authors, at the start of his legal career. Since then, much has changed. The Federal Circuit was created and given exclusive jurisdiction over patent appeals. The Supreme Court, the Federal Circuit, the district courts, and the U.S. Claims Court have published additional precedent, refining the law and its application. Congress has made a few changes to the law, although the majority of controlling statutes and types of available awards remain much the same. Yet, since 1977 the interpretation and application of the law has shifted in many ways.

Claims With Ranges, the Result-Effective Variable, and In re Applied Materials

Tom Brody

Claims can be drafted to require a parameter associated with a value (number), range, or algorithm. Where a claim includes a parameter associated with a value, range, or algorithm, enhanced resistance to obviousness rejections can result because of case law requiring that the prior art disclose overlap and case law requiring the prior art disclose a goal-to-be-achieved in optimizing the value of the parameter. Case law requiring overlap is In re Peterson and In re Geisler, while case law requiring that the prior art disclose a goal-to-be-achieved in optimizing the parameter is In re Antonie and In re Boesch. In re Applied Materials describes both requirements. Rebuttal strategies include arguing that the prior art fails to disclose the same parameter as that required by the claim. Another strategy is to argue that the prior art fails to disclose one or both of overlap and the goal. Yet another type of rebuttal is to demonstrate that the prior art’s disclosed goal is associated with a parameter, but that it is not the same type of parameter as that is recited in the claim. Application of the above cases by the Board and examiners is unpredictable, because the Board and examiners sometimes base the rejection solely on In re Aller or only In re Gal (”design choice”). In re Aller and In re Gal case law are of low-stringency, and these bodies of case law work to the disadvantage of the inventor.

''Adapted to'' After Aspex

Sean Burke

A recent trio of Federal Circuit cases has exposed uncertainty about the meaning of the linking phrase “adapted to.” Under the new intrinsic evidence standard, “adapted to” is initially presumed to mean “configured to,” but may be broadened to mean “capable of” if there exists support in the claims and specification.

The intrinsic evidence test has caused three problems for patent practitioners. First, the presumption of the narrower “configured to” meaning violates the broadest reasonable interpretation standard at the Patent & Trademark Office. Second, the use of intrinsic evidence unavoidably imports limitations from the specification into the claims. Finally, litigators have exploited, and likely will continue to exploit, the two definitions of “adapted to” by advocating either the broad definition or the narrow definition, depending upon whether the party owns the patent in question.

Trading on the Outcomes of Patent Challenges Short-Selling Petitioners and Possible Modifications to the Inter Partes Review Process

Feng Ye

Imagine investing in a pharmaceutical company A that sells drug B. Before investing, you researched company A and saw its high profit margin and its monopoly over drug B were protected by a patent. Naturally, you were excited about your research results, so you purchase company A’s stock. After purchasing, someone tells you that the patent covering drug B is invalid and he shorted – basically, bet against – the stock of company A. You are confident about your research on company A, so you ignore him. Later, while attending an investment conference, you overhear a hedge fund manager brag about successfully short-selling stock. You eavesdrop closer, as the manager whispers about driving a company’s stock price down by challenging its patents. Later, you find out that the hedge fund manager publically expressed interest in aggressively challenging low quality patents through inter partes review. While researching inter partes review, you find that Company A’s patent covering drug B was just targeted in a petition for inter partes review.

An Overview and Comparison of U.S. and Japanese Patent Litigation

Kyle Pietari

In recent decades, patent systems have taken a lead role in shaping the global economy. This trend has been particularly clear in the U.S. and Japan, two of the world’s largest economies that are home to two of the most utilized patent systems. Many people are familiar with how patents are enforced in one of these nations, but not the other. With globalization, patent litigation is becoming an increasingly international practice, and understanding the fundamentals of patent litigation in multiple key jurisdictions can be of crucial importance for a party to a patent dispute.
