Amazon has filed a Request for Director Review challenging the PTAB’s claim construction of its remote desktop patent (U.S. 8,934,887).

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.
CISCO SYSTEMS, INC. v.UMBRA TECHNOLOGIES LTD.
Cisco’s authorized response rebuts Umbra’s claim‑construction arguments, emphasizing that the Board’s interpretation of “end‑to‑end tunnel” aligns with the intrinsic record and that Umbra’s expert and prosecution‑history arguments lack support.

It asks the Director to vacate the institution and terminate the proceeding.
