A challenge by
PTAB’s opinion ignored Google and LG’s primary argument, the nonprecedential opinion by Judge Raymond T. Chen said.
Conversant Wireless Licensing SARL has a patent for a locator function that uses a finding service to allow users to locate members of a defined group of friends. For the function to work, the user must pre-register with the finding service.
Google LLC and LG Electronics Inc. made two arguments to the PTAB that the locator system is unpatentable.
But PTAB’s final written decision said the petitioners’ arguments failed without mentioning one of the arguments, the court said. When a PTAB analysis doesn’t address key arguments, it must be vacated and remanded, it said.
Judges Kathleen M. O’Malley and Kara F. Stoll joined the opinion.
Paul Hastings LLP represented Google and LG. Ascenda Law Group PC represented Conversant Wireless.
The case is Google LLC v. Conversant Wireless Licensing SARL, Fed. Cir., No. 2017-2456, 11/20/18.
