The Federal Circuit on February 24th affirmed the Delaware District order in Jazz Pharm., Inc. v. Avadel CNS Pharm., LLC., 2023-1186, that Jazz delist from the Orange Book its Patent 8,731,963 directed to a REMS to control access to its drug Xyrem, also known as gamma hydroxyl butyrate (GHB) which was misused to facilitate rape, the “date rape” drug.” The decision considered whether to list a drug in the Orange Book was proper. Patents may be listed in the Orange Book if it either claims the drug or methods of using the drug. 21 U.S.C. § 355(b)(FDCA) and 21 C.F.R. § 314.53(b)(1). Jazz contended that patent law did not provide the correct framework determining whether a patent should be listed in the Orange Book. Both the statute and rule look to the patent claims to determine if a patent claims either the drug or a method of using the drug. Here the issue was whether the ‘963 claims were directed to a method of using Xyrem.<... Read more

CareDx is the exclusive licensee of U.S. Patents 8,703,652, 9,845,497, and 10,329,607 entitled “Non-Invasive Diagnosis of Graft Rejection in Organ Transplant Patients” owned by Stanford. The patents describe diagnosing or predicting organ transplant status by using methods to detect a donor’s cell-free DNA (“cfDNA”). When an organ transplant is rejected, the recipient’s body, through its natural immune response, destroys the donor cells, thus releasing cfDNA from the donated organ’s dying cells into the blood. The increased levels of donor cfDNA, which occur naturally as the organ’s condition deteriorates, can be detected and used to diagnose the likelihood of an organ transplant rejection. Claim 1 of the ’652 patent reads (simplified):<... Read more

Last month, the Federal Circuit issued a non-precedential decision affirming the PTAB’s holdings in two final written decisions. P Tech, LLC (herein “P Tech”) appealed the PTAB decisions holding that claims 1 and 4 of U.S. Patent 9,192,395 (herein “’395 patent”) and claims 1-20 of U.S. Patent 9,149,281 (herein “’281 patent”) are unpatentable because they would have been obvious over the cited prior art, U.S. Patent 6,331,181 (herein “Tierney”) in view of U.S. Patent 5,518,163 (herein “Hooven”).P Tech, LLC, v.

Colgate-Palmolive Co. appealed the Examiner’s rejection of U.S. Application No. 15/539,725 (filed June 26, 2017) as indefinite under 35 U.S.C. §112(b) and obvious under §103 in light of U.S. Application No. 2007/0025928 A1 (published February 1, 2007), “Glandorf.” The PTAB reversed the Examiner’s rejections under §112(b) and several of the Examiner’s rejections based on the Glandorf reference but affirmed an obviousness-type double patenting rejection over U.S. Patent No. 10,350,151 B2 (issued July 16, 2019) to Qiao in view of Glandorf. The Board quickly dispatched the Examiner’s indefiniteness rejection based on the claims’ express limitation that the complex must have a 20:1 phosphorous to zinc mole ratio before focusing on the obviousness rejections.<...
