Detailed Summary
Petitioner 3Shape A/S et al. initiated a Petition challenging the validity of Patent No. 11234798, asserting that all twenty claims are unpatentable under 35 U.S.C. §103. The core argument is that the claimed system for generating a 3D model of dentition by removing soft tissue components from contiguous occlusal scans would have been obvious to a person having ordinary skill in the art (PHOSITA). Specific grounds detail how combining Zhang and Babayoff provides the foundation, with additional references like Fisker, Dillon, and Johnson providing necessary limitations for specific claim sets. The petitioner contends that these combinations represent expected improvements within the field of medical imaging/dentistry.
