In Ex parte Freeman (USSN 16/270,259; TC 1600; Appeal 2023-000512, the underlying application being referred to herein as the “Freeman application”), a finding of obviousness and obviousness-type double patenting (ODP) was reversed on May 24, 2024. Freeman’s application was examined by Devang Thakor initially, but the case was taken over by another primary examiner, Nicole Babson, whose position was supported by Supervisor Patent Examiners, David Blanchard and Bethany Barham.<...

Recently Judge Connolly, Chief Judge of the District Court of Delaware had an opportunity of deciding three motions for summary judgment filed by CareDX in its litigation with Natera, Natera, Inc. v. CareDX, Inc, Dist. DE, CA 20-38, that one patent was invalid as being directed to patent ineligible subject matter. The patents are U.S. Patent Nos. 10,597,724 (‘724), 10,655,180 (‘180), and 11,111,544 (‘544). The ‘724 and ‘180 patents are directed to methods of observing DNA in samples taken from patients. The ‘544 patent is directed to a method of “preparing a preparation of amplified DNA” from the sample of an individual to observe the DNA of a second individual in the sample. The Court found that one claim in each patent was representative of all claims in the respective patent. These representative claims are:<... Read more

In Cellect the relation between the patents is shown below:

On July 10, 2023, the Patent Trial and Appeal Board (PTAB) reversed an examiner’s finding of obvious on the basis of a failure to show a motivation to modify the prior art and a lack of a reasonable expectation of success. The appeal (No. 2023-002080, USSN 15/558,153, Technology Center 1700) of Ex parte MARK HETHERINGTON began with the filing of a Notice of Appeal on May 13, 2022, after filing the national stage application on September 13, 2017.

The Federal Circuit on June 30 granted a petition for re-hearing en banc of its per curiam decision in LKQ Corp. v. GM Global Tch. Operations, LLC. finding the PTAB had correctly decided that GM’s design patent D797,625 was not unpatentable, i.e., valid. The issue raised was whether the Federal Circuit’s rulings in Durling v. Spectrum Furniture Co., Inc., 101 F.3d 100 (Fed. Cir. 1996); In re Rosen, 673 F.2d 388 in (C.C.P.A. 1982) followed by the PTAB in its decision created a “rigid” rule for obviousness in design patent in violation of Supreme Court’s 2007 KSR decision overturning the Federal Circuit’s rigid rule for obviousness of utility patents, the “teaching, suggestion motivation“ (TSM) test for obviousness. <...

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. <... 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
