Volkswagen Group of America successfully convinced the PTAB to institute review, demonstrating a reasonable likelihood of prevailing on claim 1's obviousness over Weese. The Board instituted review for all 18 claims and grounds due to procedural deficiencies by the Patent Owner.
Caption Health, Inc. et al. v.University of British Columbia
Caption Health, Inc.'s IPR challenge against the University of British Columbia's patent was denied by the PTAB. The Board found that the combination of prior art references failed to teach or suggest critical elements related to quality assessment in echocardiographic image analysis.
MIM Software Inc. et al. v.EXINI Diagnostics AB, Inc. et al.
MIM Software and EXINI Diagnostics have settled their dispute over U.S. Patent 11,941,817 and filed a joint motion to terminate the inter partes review. The Board is asked to end the proceeding under 35 U.S.C. §317(a).
MIM Software Inc. et al. v.EXINI Diagnostics AB, Inc. et al.
MIM Software Inc. successfully petitioned to institute IPR against EXINI Diagnostics AB, Inc.'s patent (11941817) on grounds of anticipation and obviousness. The Board found reasonable likelihood that the claims are unpatentable based on prior art references like Renisch and Zhao.
GE Healthcare Ltd. et al. v.The Johns Hopkins University et al.
GE Healthcare petitions the PTAB to invalidate three claims of a Johns Hopkins FAP‑targeting radiopharmaceutical patent, asserting obviousness over US‑633, US‑121, Meletta and Jansen references.
Dentsply Sirona Inc. v.Osseo Imaging, LLC
The PTAB granted Dentsply Sirona’s petition to institute an inter partes review of Osseo Imaging’s dental densitometry patent (U.S. 6,944,262). The Board found a reasonable likelihood of unpatentability for claims 1, 2, 4, and 6 based on multiple prior‑art references. Institutional discretion factors favored proceeding despite parallel district cases.
Dentsply Sirona Inc. v.Osseo Imaging, LLC
Dentsply Sirona has filed a petition to institute an IPR against Osseo Imaging’s 6,381,301 patent covering dental and orthopedic CT densitometry. The challenger asserts the claims are anticipated or obvious over Arai and Pelc references, especially when combined with Cann and Rothman teachings. The petition seeks a finding that claims 1‑8 and 10‑20 are unpatentable.
MIM Software Inc. et al. v.Progenics Pharmaceuticals, Inc. et al.
MIM Software has filed a petition to invalidate Progenics' U.S. Patent 11,894,141, asserting that its claims on prostate‑cancer imaging are obvious over prior‑art references such as Maier, Huang and Armor. The petition seeks institution of the IPR and argues against discretionary denial.
MIM Software Inc. et al. v.Progenics Pharmaceuticals, Inc. et al.
The PTAB denied MIM Software's request to institute IPR against Progenics Pharmaceuticals regarding a medical image analysis patent. The denial was based on Petitioner's failure to properly construe the key term 'risk map,' proposing multiple ambiguous definitions without adequate justification.
ITM Isotope Technologies Munich SE v.The Johns Hopkins University et al.
ITM Isotope Technologies Munich SE petitions the PTAB to invalidate claims of Johns Hopkins' ’201 patent covering low‑molecular‑weight FAP‑α imaging agents, arguing obviousness, lack of enablement, insufficient written description, and indefiniteness.
Precision Cancer Technologies Inc. v.Oncoustics Inc.
Oncoustics successfully defended the Board’s decision to deny institution of an IPR filed by Precision Cancer Technologies. The patent owner showed the petitioner failed to prove the primary reference disclosed a single static set of raw RF ultrasound data, and the petitioner’s new arguments were untimely.
Precision Cancer Technologies Inc. v.Oncoustics Inc.
Precision Cancer Technologies Inc.'s IPR challenge against Oncoustics Inc. was denied by the PTAB, failing to meet the reasonable likelihood of prevailing standard. The Board found Petitioner failed to sufficiently demonstrate that prior art processed a 'single static set' of raw RF ultrasound data.
Garmin International, Inc. v.Cardiacsense LTD
The PTAB denied Dexcowin Global’s inter partes review petition against Aribex’s portable x‑ray device patent, finding no reasonable likelihood of success on any claim. The Board rejected anticipation and obviousness arguments centered on a continuous high‑voltage DC power limitation.
Olympus Corporation et al. v.Optimum Imaging Technologies LLC
Olympus and Optimum Imaging have reached a settlement-in-principle in their imaging patent dispute, seeking a stay of court deadlines and planning to dismiss the case.
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.
