As a patent attorney, here is an overview of known litigation involving US Patent 9185522:

1. Inter Partes Review (IPR) before the Patent Trial and Appeal Board (PTAB) and subsequent appeal to the Federal Circuit:

  • Case Name: UBER TECHNOLOGIES, INC. v. X ONE, INC.
  • Plaintiff(s) (Petitioner at PTAB): Uber Technologies, Inc.
  • Defendant(s) (Patent Owner at PTAB): X One, Inc.
  • Jurisdiction: Patent Trial and Appeal Board (PTAB) and subsequently the U.S. Court of Appeals for the Federal Circuit.
  • Case Number: Appeal No. 19-1164 (Federal Circuit)
  • Filing Date (Federal Circuit decision date): May 5, 2020.
  • Outcome/Current Status: Uber sought inter partes review, arguing that claims of the patent were obvious in light of prior art. The PTAB initially held the claims were not unpatentable. However, the Federal Circuit reversed the PTAB's decision, finding that the Board erred in determining the obviousness of the limitation "software . . . to transmit the map with plotted locations to the first individual" in view of prior art. The Federal Circuit concluded that a person of ordinary skill would have been motivated to combine prior art teachings to achieve this limitation, given that terminal-side plotting and server-side plotting were known, predictable solutions. This case specifically referenced US Patent No. 8,798,647, which is a related patent sharing similar technology regarding GPS data exchange and a "Buddy Watch application."
