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. <...

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

Claims to a Spread-Spectrum Method For Sending Data Over a Communications Channel Are Patent Ineligible under Section 101

Attorney: Marina I. Miller, Ph.D.
August 23, 2021

Plaintiff Zyrcuits IP LLC has sued Defendants Acuity Brands, Inc. and Universal Electronics Inc. for infringement of claim 4 of U.S. Patent No. 6,671,307 (the ‘307 patent). Defendants argued that Zyrcuits's complaints should be dismissed because the ‘307 patent is invalid under 35 U.S.C. § 101 for failing to claim patentable subject matter. Applying the two-step framework from Alice, the court found that the ‘307 patent was invalid under § 101, as the claims of the ‘307 patent are directed to the abstract idea of grouping data together with a single code and do not contain any inventive concept....

Two-Step Eligibility for Genomic Analysis Systems

February 4, 2021

For practitioners at the USPTO, the reversal of a 101 rejection in Ex parte Patil (PTAB January 7, 2021), APJs Grimes, Scneider and Valek, in Appeal 2020-002775 should be interesting if not provide some light on the dance floor for doing the two-step with the USPTO.

The invention focused on assessing genetic variability with a system including databases and processors and as recited in Claim 27 U.S. 15/169,498:<... Read more

A Diagnostic Patent Is Found Patent Eligible At the Federal Circuit

Attorney: Richard D. Kelly
August 4, 2020

In March the Federal Circuit reversed a lower court decision finding Illumina’s patents (U.S.Ps. 9,580,751 and 9,738,931) for diagnosing Down’s Syndrome to be patent ineligible, 952 F.3d 1367 (Fed. Cir. 2020). On August 3, the Federal Circuit denied a petition for rehearing and rehearing enbanc but did issue a new decision adding the term “human-engineered” in several portions of the opinion discussing the separation of fetal DNA from maternal DNA which the inventors had discovered were of different sizes, fetal cell DNA is shorter than the maternal DNA. The inventors recognized that the DNA to be analyzed for genetic aberrations was that of the fetus. The problem was to isolate the small amount of fetal DNA from the maternal DNA so the fetal DNA could be analyzed for genetic aberrations. Prior to the invention there was no known way to distinguish and separate maternal DNA from the tiny fraction of fetal DNA present. The inventors found that by selectively removing DNA having more than 500 or 300 base pairs they could produce a sample where the fetal DNA content in the sample would be enriched and analyzed. The following claim is exemplary:<... Read more

Solicitor General on Patent Eligibility

Attorney: Richard D. Kelly
December 16, 2019

The Solicitor General (SG) was invited by the Supreme Court to provide comments on the certiorari petitions filed by Berkheimer and Hikma to review the Federal Circuit's 101 decisions adverse to them. The two briefs have numerous similarities including identifying the Court's decision in Bilski[1]as starting the patent eligibility confusion by not grounding its decision on interpreting the meaning of the 35 U..S.C. 101 terms "process, machine, manufacture, [and] composition of matter." The SG asserts that in Bilski the Court did not ground its decision on the stature terms but instead found three exceptions to be not required by the statutory text: laws of nature, physical phenomenon, and abstract ideas. While these concepts are found earlier Supreme Court decisions, Bilski represented the first time they were used independent of the statutory language or constitutional concept of the "useful arts." The SG then described Mayo[2] as continuing the Court's Bilski practice of not tying patent eligibility to any of the statutory or Constitutional language. Alice[3] characterized the Mayo decisional approach as a two step process.... Read more
