The Flip Side of Reasonable Expectation of Success is Unpredictability
The Federal Circuit in a precedential opinion in Osai Pharmaceuticals, LLC v Apotex et al (Fed. Cir., October 4, 2019) http://www.cafc.uscourts.gov/sites/default/files/opinions-orders/18-1925.Opinion.10-4-2019.pdfreversed the USPTO's determination of obviousness in an IPR for patent claims directed to the treatment of non-small cell lung cancer (NSCLC). Just reading the background of the first three or four pages of the decision, it was already apparent that the Court was not going to be affirming the PTAB's decision. Notably:
Prior Art Introduced During Prosecution Has Important Implications for 101 Challenges
Five years after Alice Corp. Pty. v. CLS Bank Int'l, 573 U.S. 208 (2014) and the institution of the Alice test, district courts are still wading through precedent set by the Federal Circuit while it attempts to apply the test. Recently, one New Mexico District Court turned to prior art introduced during the prosecution process that was aimed at the questions of novelty and non-obviousness to determine whether there was an "inventive concept" for the Alice/Mayo test.
Prosecution History Estoppel And Amendments Tangential To Patentability
The doctrine of equivalents is an equitable exception to the basic concept that the patent claims define the limit of claim protection. It is intended to prevent one from making an insubstantial change to a claimed invention to avoid infringement which is defined by the function-way-result test. The doctrine is limited by the prior art, dedication to the public, and prosecution history estoppel.
Specification Must Adequately Disclose the Claimed Invention to Avoid Invalidation for Lack of Written Description
Drs. Stephen Quake and Christina Fan ("Quake") appealed a decision of the U.S. Patent and Trademark Office Patent Trial and Appeal Board ("the Board") finding the four claims of Quake's U.S. Patent 8,008,018 and Claim 25 of their U.S. Application No. 12/393,833 unpatentable for lack of written description.
Thinking Outside the (Utility Patent) Box - Don't Overlook Design Patent Protection in the Life Sciences
Design patents are very different from utility patents in that design patents only protect the ornamental features of an invention. In contrast to utility patents, the design is defined in scope by the content of the drawings rather than the words of a set of claims. Further, design patents have a 15 year term, as opposed to 20 years from filing for utility patents.
Non-Limiting Clauses and Written Description Based on Substantially Equivalent Disclosure
Nalpropion Pharmaceuticals, Inc. v Actavis Laboratories FL, Inc (Fed. Cir. Aug. 15, 2019) is a precedential opinion written by Judge Lourie with Judge Wallach and a dissent from Judge Prost in a case centered on an ANDA litigation in which Actavis sought approval for their generic version to Nalpropion's patents for the Contrave® product. Footnote 1 in the opinion outlines the rather complex history of the ownership/license interests as they changed over time.
An Approach to Pharma Life Cycle Management
Every innovative pharma company faces the same challenge, how to delay the patent cliff. The existence of the "skinny viii" (21 U.S.C. § 355(j)(2)(A)(viii)) makes developing additional FDA approved indications unattractive from an LCM viewpoint.
