Microchip Technology, Inc. v.Aptiv Technologies AG et al.
Microchip Technology initiated an IPR challenging the validity of Aptiv Technologies' patent 9460037, arguing that the claimed USB hub features are obvious. The petition focuses on combining prior art (Chang and Chang II) to demonstrate predictable design choices in computer networking hardware.
Capital One, National Association et al. v.--
Capital One National Association filed an IPR challenging Implicit, LLC's patent 8056075 on grounds of obviousness (35 U.S.C. §103). The petition asserts that the claims are rendered unpatentable by various combinations of prior art references including Fowlow and Kimera.
Hulu LLC et al. v.--
Hulu LLC and Capital One filed an IPR petition challenging 13 claims of Patent No. 6976248, arguing they are obvious over various combinations of prior art references (Johnson, Parthasarathy, Fowlow). The petitioner asserts that the claimed software delivery methods lack inventive step under 35 U.S.C. §103(a).
Cisco Systems, Inc. v.Lionra Technologies Limited
The PTAB found claims unpatentable under 35 U.S.C. § 103(a) based on a combination of prior art references (Gai, Yip, Kwan, and Georgiou). The Board determined that an ordinary skilled artisan would have been motivated to combine these teachings to enhance network security and implement advanced ACL functions.
Cisco Systems, Inc. v.Lionra Technologies Limited
Cisco Systems, Inc. successfully petitioned the PTAB to challenge Lionra Technologies Limited's patent (7623518) on grounds of obviousness and anticipation. The Board found reasonable likelihood of success for Cisco regarding several claims related to dynamic access control lists and network security.
Lenovo (United States) Inc. et al. v.Intellectual Ventures II
Lenovo successfully challenged several claims of Intellectual Ventures II's patent (8474016) in an IPR proceeding, leading the PTAB to institute on all challenged claims. The Board found strong evidence that prior art references like Neufeld and PCI Bridge Spec taught or rendered obvious various limitations of the asserted claims.
Lenovo (United States) Inc. et al. v.Intellectual Ventures II
Lenovo challenged Intellectual Ventures II's patent (7325140) in an IPR, arguing the claims are obvious over prior art related to remote device management. The Board found that Lenovo showed a reasonable likelihood of prevailing on several grounds, particularly citing Neufeld and IPMI as teaching key limitations. This institution decision moves the case toward trial, focusing on complex technical combinations of access control protocols.
Lenovo (United States) Inc. et al. v.Intellectual Ventures II
Lenovo challenges 7325140 in an IPR, arguing the claims are obvious over various combinations of prior art related to remote device management. The petitioner contends that allowance was based on low-level implementation details already disclosed in references like Neufeld and IPMI/Lawrence.
Lenovo (United States) Inc. et al. v.Intellectual Ventures II
The Board found that U.S. Patent No. 7,325,140 B2 is unpatentable due to obviousness over prior art references. Specifically, the combination of Neufeld and Syvanne renders claims 11 and 12 obvious, while other combinations involving IPMI render multiple claims invalid.
Lenovo (United States) Inc. et al. v.Intellectual Ventures II
The Board found that claims 1–3, 6–9, 12, and 14–17 are unpatentable over Neufeld grounds. Specifically, the Board determined that prior art reference Neufeld taught multiple limitations of the claimed apparatus, including distinct bus controllers and encrypted communication handling. The combination of IPMI/Huckins was rejected as lacking motivation to combine or relying on hindsight.
Cisco Systems, Inc. v.Croga Innovations Ltd.
Cisco Systems' IPR challenge against Croga Innovations regarding network security claims was denied by the PTAB. The Board found that the cited prior art did not teach or suggest the critical 'internal firewall' limitations required by the patent claims.
Cisco Systems, Inc. v.Lionra Technologies Limited
Cisco Systems successfully petitioned to institute IPR against Lionra Technologies regarding patent 7,738,471, challenging claims related to high-speed packet header processing.
Fortinet, Inc. v.Croga Innovations Ltd.
Fortinet's attempt to invalidate Croga Innovations Ltd.'s patent on network security claims was denied by the PTAB. The Board found that Fortinet failed to demonstrate obviousness over prior art, specifically Delco and Adams. This denial maintains the validity of key virtualization and firewall technology for Croga.
Microchip Technology, Inc. v.Aptiv Technologies AG et al.
Microchip Technology filed a Petition with the PTAB challenging claims of Aptiv Technologies' patent 9619420, arguing that the USB hub technology is obvious. The petitioner asserts that combining existing components like host-to-host bridges and dual-role switching functionality renders the claimed invention predictable to a person skilled in the art.
Microchip Technology, Inc. v.Aptiv Technologies AG et al.
Microchip Technology initiated a Petition challenging the obviousness of claims in patent 10545899, which relates to USB hubs and connectivity. The petitioner argues that the claimed features are predictable combinations of prior art like Chang and Chang II.
Cisco Systems, Inc. v.Lionra Technologies Limited
Cisco Systems challenges Lionra Technologies' patent (7623518) in an IPR, asserting that multiple claims are obvious over combinations of prior art. The petitioner focuses on network access control list (ACL) improvements and dynamic packet handling techniques using references like Gai, Yip, Kwan, and Georgiou.
