SCOTUS Denies Petition to Review CAFC Precedent on Justification for Primary Reference Selection

The U.S. Supreme Court on Monday, March 18, denied a petition filed by patent owner Jodi A. Schwendimann asking the Court to review a decision of the U.S. Court of Appeals for the Federal Circuit (CAFC) that affirmed a Patent Trial and Appeal Board (PTAB) determination that Schwendimann’s patents were obvious. The petition specifically asked the Court to review the CAFC’s holding that Schwendimann’s argument that “justification for selection of a primary reference is a necessary step to guard against hindsight bias for the motivation to combine references” was unsupported by Federal Circuit case law.

Responding to Obviousness Rejections in Light of the USPTO’s New Guidance

The United States Patent and Trademark Office (USPTO) recently released new guidance to patent examiners on making obviousness rejections. The guidance focuses on post-KSR precedential jurisprudence from the U.S. Court of Appeals for the Federal Circuit. Some of the guidance is fairly mundane, some of it is not. The purpose of this article is to propose a few responses one might use to counter rejections that apply certain problematic aspects of the new guidance.

CAFC Affirms PTAB Finding that Reasonable Pertinence Proves Analogous Art

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a brief opinion authored by Judge Chen today that rejected Daedalus Blue LLC’s appeal of a Patent Trial and Appeal Board (PTAB) decision finding certain claims of its patent on a data management system unpatentable. The PTAB held that U.S. Patent No. 8,671,132 was unpatentable as obvious over combinations of three prior art references: “Gelb”, “Tivoli”, and “Callaghan.” Daedalus in part argued on appeal that the Board incorrectly found that Gelb is analogous art because Gelb “is not reasonably pertinent to the problems identified in the ’132 patent.”

USPTO Issues Updated Obviousness Guidance Tracing 15 Years of Case Law Following KSR

On February 27, the U.S. Patent and Trademark Office (USPTO) published a notice in the Federal Register providing updated guidance for agency decision-makers on making proper determinations of obviousness under the U.S. Supreme Court’s 2007 ruling in KSR International Co. V. Teleflex Inc. While the USPTO’s examiner guidance doesn’t constitute substantive rulemaking, it traces 15 years of case law from the U.S. Court of Appeals for the Federal Circuit to clarify several areas of confusion stemming from the Supreme Court’s calls for a flexible approach to the obviousness analysis for patent validity.

The ‘Lead Compound’ Rule: Problems and More Problems

On August 22, 2023, the U.S. Court of Appeals for the Federal Circuit issued yet another decision reinforcing what can only be described as the “lead compound” rule for challenging pharmaceutical and other chemical compound patents on the basis of obviousness…. The Federal Circuit has been utilizing the “lead compound” construct since around 2000. The Sun panel cited an earlier decision which couched the construct as something the court “ordinarily” employs. Otsuka Pharm. Co., Ltd. v. Sandoz Inc., 678 F. 3d 1280, 1289 (Fed. Cir. 2012). That earlier decision cited yet an earlier decision which stated that the “lead compound” methodology is used “in general.” Esai Co. v. Dr. Reddy’s Labs., Ltd., 533 F. 3d 1353, 1359 (Fed. Cir. 2008).
