Roku, Inc. v.VideoLabs, Inc.
Roku challenged VideoLabs' patent 8291236 in an IPR proceeding, alleging that the core concepts of bridging security systems were anticipated by prior art. Petitioner argues that claims related to dynamic encryption and entitlement management are obvious over references like Russ, Robert, and Eskicioglu.
Intel Corporation et al. v.Telefonaktiebolaget LM Ericsson
Intel and others challenged Ericsson's '659 Patent, arguing that its deblocking filter equations are obvious over prior art references like Fu and Bjontegaard. The petition asserts that a Person Having Ordinary Skill in the Art would have routinely optimized the claimed coefficients using existing knowledge of high-pass filters.
Intel Corporation et al. v.Telefonaktiebolaget LM Ericsson
Intel Corporation et al. filed an IPR petition challenging Ericsson's patent on deblocking filter features, asserting obviousness over various prior art references. The core arguments focus on how asymmetric decision-making and specific offset equations are routine modifications of existing video compression techniques.
Innoscience America, Inc. et al. v.Infineon Technologies Austria AG
Innoscience America challenges Infineon's patent on power semiconductor packaging, asserting obviousness under 35 U.S.C. § 103. The petitioner argues that combining known device structures with established packaging techniques renders the claimed features predictable to a Person Having Ordinary Skill in the Art.
Roku, Inc. v.VideoLabs, Inc.
Roku successfully petitioned to institute an IPR against VideoLabs regarding claims related to conditional access and DRM technology. The Board found sufficient evidence of anticipation (102) and obviousness (103) over prior art 'Russ' and 'Robert.'
Roku, Inc. v.VideoLabs, Inc.
Roku successfully petitioned for the institution of IPR against VideoLabs regarding claims related to Conditional Access and Digital Rights Management. The Board found that Petitioner's evidence sufficiently supported unpatentability under 35 U.S.C. §§ 102 and 103, advancing the dispute into the review phase.
Roku, Inc. v.VideoLabs, Inc.
Roku, Inc. successfully convinced the PTAB that its claims related to conditional access and DRM systems were unpatentable over prior art (Russ). The Board found a reasonable likelihood of prevailing on both anticipation (§102) and obviousness (§103), leading to institution of the IPR.
Roku, Inc. v.VideoLabs, Inc.
Roku, Inc. successfully convinced the PTAB to institute its challenge against VideoLabs' patent claims under 35 U.S.C. § 102 (Anticipation). The Board found sufficient support for anticipation over prior art 'Russ,' while denying institution on obviousness grounds.
Intel Corporation et al. v.Telefonaktiebolaget LM Ericsson
The PTAB denied Intel's IPR against Ericsson, finding that the combination of prior art references did not teach or suggest the claimed limitations. The Board upheld the patent owner's position regarding the technical differences in filtering processes and failed to find a reasonable likelihood of prevailing on any challenged claim.
Intel Corporation et al. v.Telefonaktiebolaget LM Ericsson
Intel Corporation's attempt to invalidate Ericsson's video coding patent was denied by the PTAB on obviousness grounds (103). The Board ruled that Petitioner failed to demonstrate that specific numerical coefficients in the claimed offset equations were 'result-effective variables.'
Innoscience America, Inc. et al. v.Infineon Technologies Austria AG
The PTAB denied the institution of an IPR against Infineon's patent, finding that Innoscience failed to demonstrate a reasonable likelihood of prevailing on obviousness grounds.

Inari Agriculture, Inc. v.Corteva Agriscience LLC et al.
Inari Agriculture challenged Corteva Agriscience's patent covering TC1507 plant biotechnology, arguing the claims fail enablement under 35 U.S.C. §112(a) due to missing germplasm deposits. The petitioner also asserted anticipation and obviousness over prior art (Barbour) under both §102 and §103.
Inari Agriculture, Inc. v.Corteva Agriscience LLC et al.
Inari Agriculture successfully petitioned to institute an IPR against Corteva Agriscience's GMO patents based on prior art from Barbour. The Board found a reasonable likelihood of prevailing regarding anticipation and obviousness over the cited publication, moving the case toward trial.
Inari Agriculture, Inc. v.Corteva Agriscience LLC et al.
The PTAB Board upheld the validity of U.S. Patent No. 8,901,378 B2 after finding that the TC1507 germplasm was publicly available prior to the application's filing date. The Board concluded that this availability satisfied priority requirements and prevented Barbour from qualifying as prior art under § 102.
Phison Electronics Corporation v.Vervain, LLC
