patent denied

Curio Bioscience, Inc. v.Prognosys Biosciences Inc. et al.

· IPR2025-00192

The PTAB denied Curio Bioscience's IPR challenge against Prognosys and 10X Genomics, finding no reasonable likelihood of prevailing on grounds of anticipation (102), obviousness (103), or written description (112). The Board upheld the validity of the challenged claims in spatial omics/assay systems technology.

patent denied

Curio Bioscience, Inc. v.Prognosys Biosciences Inc. et al.

· IPR2025-00193

The PTAB denied Curio Bioscience's IPR against Prognosys/10X Genomics, finding no grounds for invalidity based on obviousness (Cantor/Armani) or anticipation (Frisen). The Board concluded that the prior art did not teach the necessary combination elements of spatially encoded biological assays.

patent denied

Curio Bioscience, Inc. v.Prognosys Biosciences Inc. et al.

· IPR2025-00236

The PTAB denied Curio Bioscience's IPR challenge against Prognosys and 10X Genomics, finding that the asserted claims were not obvious or anticipated by the prior art. The Board specifically rejected arguments linking Cantor to spatial analysis in tissue sections.

patent denied

Curio Bioscience, Inc. v.Prognosys Biosciences Inc. et al.

· IPR2025-00237

Curio Bioscience, Inc.'s IPR challenge against Prognosys and 10X Genomics was denied by the PTAB. The Board found that Petitioner failed to demonstrate a reasonable likelihood of prevailing on grounds of obviousness (over Cantor/Armani) and anticipation (by Frisen).

patent instituted

Ajinomoto Co., Inc. v.AbTis Co., Ltd.

· IPR2025-00283

Ajinomoto Co., Inc. successfully convinced the PTAB to institute an IPR against AbTis Co., Ltd.'s patent (11896675) covering Antibody-Drug Conjugates (ADCs). The Board found sufficient evidence for institution on multiple grounds of anticipation and obviousness regarding claim 11.

patent null

NeoGenomics Laboratories, Inc. v.Natera, Inc.

· IPR2024-00812

NeoGenomics challenges Natera's patent covering cell-free DNA analysis methods in an IPR petition. The petitioner asserts that the claimed method is anticipated or obvious over multiple prior art references, including Forshew and Pieprzyk/May.

patent null

Illumina, Inc. v.Molecular Loop Biosciences, Inc.

· IPR2024-00964

Illumina Inc. has filed a petition challenging eight claims related to Next-Generation Sequencing (NGS) technology at the PTAB. The core argument is that the challenged methods are obvious over combinations of prior art, specifically involving dual-indexing techniques and sequencing platform substitutions. This challenge targets fundamental aspects of NGS methodology.

patent instituted

Illumina, Inc. v.Molecular Loop Biosciences, Inc.

· IPR2024-00965

Illumina filed an Inter Partes Review petition challenging Molecular Loop Biosciences' patents covering dual-indexing in Next-Generation Sequencing (NGS). The petitioner argued the claims were anticipated or obvious over prior art references like Gloor and Parameswaran. The PTAB decided to institute the IPR because the Examiner failed to consider relevant prior art during prosecution.

patent null

Bio-Rad Laboratories, Inc. v.California Institute of Technology et al.

· IPR2024-01177

Bio-Rad Laboratories filed a Petition challenging the obviousness of nine claims in patent 10068051, which relates to molecular diagnostics/PCR methods. The petitioner argues that the claimed multiplexed detection techniques are straightforward extensions of existing prior art concepts found in references like Saxonov and Silverbrook.

patent null

Bio-Rad Laboratories, Inc. v.California Institute of Technology et al.

· IPR2024-01178

Bio-Rad Laboratories has filed an IPR challenging the validity of a patent covering multiplex digital PCR assays owned by California Institute of Technology et al. The petitioner argues that the claimed methods are unpatentably obvious, representing only a straightforward extension of existing nucleic acid analysis concepts.
