Lessons from Amgen v. Sanofi

Attorney: Richard D. Kelly
July 5, 2023

Amgen provides a window on the Supreme Court approach to patent issues - look to history and established policy as our patent law is not code based but rather common law based. The Court noted that the “enablement requirement” is found essentially unchanged in every version of the patent law since 1790. While Amgen concerned the enablement provision, the same approach applies to patent eligibility, the “judicial exceptions,” which have existed in our case law since the early 19th century.  In deciding Amgen the Supreme Court did not consider previous Federal Circuit decisions but looked to history of the enablement provision which involved Court decisions from the 19th and early 20th century.  While Amgen was the Court’s first antibody case, it found analogous cases which provided guidance as to how the enablement requirement had been interpreted.  Since U.S. patent law is based on common law, this is the appropriate approach to provide the needed predictability.  Without understanding the policy behind the exceptions, one will continue to wander aimlessly from one case to the next.<...

The CareDx Petition For Certiorari, Maybe This Is The One

Attorney: Richard D. Kelly
May 30, 2023

On May 16, the Supreme Court distributed the CareDX cert petition for consideration at the June 1 conference since the Respondents waived filing a reply. The CareDX family of three patents, licensed from Stanford University, U.S.Ps. 8,703,652, 9,845,497 and 10,329,607, are directed to the noninvasive diagnosis of the state of a transplanted organ. The test provides the doctor with information on whether everything is okay, or that the organ is showing signs of being rejected. Both the district court and the Federal Circuit held the patent to be patent ineligible based primarily on admissions appearing in the specification of all three patents which are identical.  Given the low success rate (recently zero) of requests for certiorari in the diagnostic/biomarker area, this raises the question as to the possibility the petition will be granted.  The CareDx petition’s chances seem better than recent certiorari petitions. <...

Amgen v. Sanofi – Impermissible Functional Claiming?

Attorney: Richard D. Kelly
May 12, 2023

On April 28 the Supreme Court heard oral arguments on Amgen’s petition of the Federal Circuit’s decision affirming the district court’s decision on JMOL that Amgen’s antibody claims lacked an enabling disclosure. Much of the argument revolved around what was the quantum of experimentation that was too much for a claim to be enabled. At the end of Sanofi’s argument its counsel cited the Morse case where the Supreme Court invalidated Morse claim 8 which defined the transmission of symbols in solely functional terms:<...

Claims Directed to Detecting Natural Phenomena Using Conventional Techniques Are Patent Ineligible

Attorney: Marina I. Miller, Ph.D.
February 22, 2023

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

Is the Supreme Court Poised to Consider the Federal Circuit's "Possession of the Invention" Definition of Written Description?

Attorney: Richard D. Kelly
October 5, 2022

The Supreme has relisted the petition for certiorari in Juno Therapeutics, Inc. v. Kite Pharma, Inc., 21-1566 where Juno petitioned for review of the Federal Circuit’s decision reported at 10 F.4th 1330 (2021) reversing the decision of the lower court finding U.S.P. 7,446,190 to not be invalid for lack of written description or enablement and awarding damages of over $1.2 billion. While the relisting of a certiorari petition does not guarantee cert will be granted, statically since 2016 between about 30 and 40% of relisted petitions have been granted. The SCOTUS blog has detailed analysis here. Considering that the overall grant rate for petitions is only about 4% this indicates that the Juno petition has a much greater than normal possibility of being granted.<... Read more
