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.

· IPR2024-01212

The PTAB found all 29 challenged claims unpatentable by a preponderance of evidence. The Board rejected the Patent Owner's argument that the invention was limited to RF neurotomy, adopting Petitioner's broader view of 'thermal ablation systems.'

patent instituted

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

· IPR2024-00625

Merck Sharp & Dohme LLC successfully petitioned to institute IPR proceedings against The Johns Hopkins University regarding anti-cancer immunotherapy claims.

· IPR2025-00136

The PTAB denied Aardevo North America's IPR petition against Agventure B.V., finding the petitioner failed to overcome compelling objective indicia of non-obviousness. The Board rejected arguments based on anticipation and obviousness, particularly concerning potato breeding methods.
