patent Final Written Decision

Merck Sharp & Dohme LLC et al. v.The Johns Hopkins University

· IPR2024-00625

The PTAB issued a Final Written Decision finding that claims 1-8 of the patent were unpatentable. The Petitioner successfully demonstrated that the MSI-H Study Record (MSR) anticipates and renders obvious most challenged claims under both § 102 and § 103. The Board ruled that the Patent Owner's objective evidence of non-obviousness was insufficient to overcome these findings.

patent final

Merck Sharp & Dohme LLC et al. v.The Johns Hopkins University

· IPR2024-00647

The Board concluded that the MSI-H Study Record inherently anticipates the claimed methods, including those requiring pre-treatment testing for microsatellite instability high or DNA mismatch repair deficient status. This decision significantly weakens the patent's validity in the context of oncology and immunotherapy.

· IPR2024-00650

The PTAB issued a Final Written Decision finding all 38 claims of the '491 patent unpatentable.
