Case: Patents/Obviousness (P.T.A.B.)

The Patent Trial and Appeal Board held that all challenged claims of Exact Sciences Corporation’s patent that relates to methods and kits for analysis of fecal samples are unpatentable as obvious over prior art, in an inter partes review by Geneoscopy Inc. The board determined that the challenged claims are obvious over various combinations of prior art, including prior art titled “Analysis of Promoter Methylation in Stool: A Novel Method for the Detection of Colorectal Cancer,” “Improved Fecal DNA Test for Colorectal Cancer Screening,” and “Method for Stabilizing Biological Samples for Nucleic Acid Analysis.”
