3Shape A/S et al. v.Medit Corporation et al.
Petitioners challenge U.S. Patent No. 9,245,374 regarding 3D voxel data processing used in medical imaging, asserting anticipation and obviousness over prior art references like Sekiguchi and Partain. The claims are broadly challenged across multiple statutory grounds (102 and 103) by 3Shape A/S et al., citing related district court litigation.
3Shape A/S et al. v.Medit Corporation et al.
3Shape A/S filed an Initial Petition challenging the validity of Medit Corporation's patent, asserting that the claims are obvious over combinations of prior art references. The petitioner targets multiple claim subsets using Trousset, Durbin, and Kariathungal as evidence of obviousness.
3Shape A/S et al. v.Medit Corporation et al.
3Shape A/S et al. filed an opening petition challenging Medit Corporation's patent (7912257) on grounds of obviousness under 35 U.S.C. § 103. The petitioners argue that the claimed real-time 3D dental scanning method is predictable when combining prior art disclosures from Kopelman and Quadling.
Dental Imaging Technologies Corporation et al. v.3Shape A/S
Dental Imaging Technologies Corporation et al. filed an Inter Partes Review challenging U.S. Patent No. 10,695,151 held by 3Shape A/S. The petitioner asserts that the patent claims related to dental shade determination are unpatentable under both anticipation (§102) and obviousness (§103).
3Shape A/S et al. v.Dental Imaging Technologies Corporation
Petitioner 3Shape A/S et al. filed a petition challenging the validity of Dental Imaging Technologies Corporation's patent claims, asserting that all 20 claimed features are obvious under 35 U.S.C. §103. The arguments rely heavily on combining prior art references such as Zhang and Babayoff to demonstrate predictable improvements in dental imaging technology.
3Shape A/S et al. v.Dental Imaging Technologies Corporation
The PTAB denied the institution of an IPR challenge against Dental Imaging Technologies Corporation's patent covering intra-oral scanning and 3D modeling. The Board found that the petitioner failed to demonstrate a reasonable likelihood of prevailing on the grounds of obviousness over combinations of Zhang and Babayoff.
