Short Summary
Geneoscopy challenges Exact Sciences' '781 patent on grounds of obviousness (103) related to colorectal cancer diagnostics. The petitioner argues that combining known methods for fecal sample processing, such as DNA methylation and blood protein testing, renders the claims unpatentable over prior art references. This challenge targets multiple diagnostic claim sets across the patent.
Detailed Summary

The petitioner asserts that numerous claims are obvious under 35 U.S.C. § 103 because they merely combine well-established diagnostic techniques found in the prior art. Specifically, the challenge focuses on the combination of fecal DNA methylation assays (Lenhard) with blood protein detection methods (Vilkin), further supported by references detailing sample stabilization and collection improvements (Itzkowitz, Kanaoka, Derks). The petition covers a broad range of claims related to colorectal cancer diagnostics, asserting that the claimed inventive steps are routine optimizations in the field.
