· IPR2024-00634

patent Final Written Decision

Fluidmaster, Inc. v.Danco, Inc. et al.

· IPR2024-00635

The PTAB panel majority found that the cited prior art references teach or suggest all limitations of claims 1-14, rendering them unpatentable under 35 U.S.C. § 103. The Board specifically construed key terms like 'overflow tube' and 'Flow Limitations' to support Petitioner’s reading, though ultimately found the overflow tube limitation was limiting in scope.

patent final

Tommy John, Inc. v.Pakage Apparel, Inc.

· IPR2024-01163

The PTAB found that the challenged claims (1-13, 15, 16) were unpatentable based on obviousness over combinations of prior art references. The Board accepted Petitioner's argument that Kitsch satisfied key limitations like 'stretch panel,' and broadly construed material requirements to favor the petitioner.

patent all challenged claims upheld

ZF Active Safety and Electronics US LLC v.Facet Technology Corp.

· IPR2025-00748

Mobileye Global's challenge to Facet Technology Corp.'s road sign recognition patent failed before the PTAB, upholding claim 15 of U.S. Patent No. 9335255. The Board found insufficient evidence that combining prior art references would render the claimed method obvious under 35 U.S.C. § 103.

patent mixed - some claims cancelled, some upheld

ZF Active Safety and Electronics US LLC v.Facet Technology Corp.

· IPR2025-00749

Mobileye Global successfully convinced the PTAB that several claims of Facet Technology's patent were obvious in light of prior art references Gallagher and Schofield. The Board found Claims 1-4, 8-13 unpatentable based on a combination of these references, while upholding the validity of other claims (5-7, 14-16).

patent instituted

Fluidmaster, Inc. v.Danco, Inc. et al.

· IPR2024-00633

Fluidmaster successfully petitioned the PTAB to institute an IPR against Danco's patent, challenging 20 claims based on obviousness (35 U.S.C. § 103). The Board adopted a narrow claim construction for 'integrally molded with,' defining it as being formed as a single structure.

· IPR2024-00634

patent instituted

Fluidmaster, Inc. v.Danco, Inc. et al.

· IPR2024-00635

Fluidmaster successfully petitioned the PTAB against Danco, Inc., leading to the institution of trial on all 14 claims. The Board found sufficient evidence that the patent's features were obvious under 35 U.S.C. § 103 using various prior art references. This decision significantly advances Fluidmaster’s challenge in related district court litigation.

patent denied

Head Sport GmbH v.Vermont Safety Developments LLC

· IPR2024-01099

The PTAB denied institution of the IPR petition filed by Head Sport GmbH against Vermont Safety Developments LLC regarding ski binding systems. The denial hinged on the Petitioner's failure to establish a reasonable likelihood of prevailing without an agreed-upon claim construction for 'release logic.'

patent instituted

Tommy John, Inc. v.Pakage Apparel, Inc.

· IPR2024-01163

Tommy John, Inc. successfully petitioned to invalidate key claims of Pakage Apparel's '974 patent based on obviousness over prior art combinations (Kitsch/Brocks). The PTAB declined discretionary denial because the petitioner showed a reasonable likelihood of prevailing and failed to demonstrate material error in prosecution history.

patent mixed - some claims cancelled, some upheld

Fluidmaster, Inc. v.Danco, Inc. et al.

· IPR2024-00633

The PTAB corrected its Final Written Decision for IPR2024‑00633, confirming that 11 of the 20 challenged claims of Fluidmaster’s toilet‑valve patent are unpatentable, while the remaining nine claims remain patentable.

· IPR2024-01442
