Appeal board initiates invalidity proceedings for key Motorola solutions patents

Global land mobile radio communications provider Hytera Communications Corporation Ltd. has learned that the Patent Trial and Appeal Board (“PTAB”) of the United States Patent and Trademark Office (“USPTO”) has accepted Hytera´s October 2017 petitions to reexamine the validity of claims in two patents of Motorola Solutions, Inc. (“MSI”), the company said.

The patents at issue, US Patent No. 8,116,284 (“the ´284 Patent”) and US Patent No. 6,591,111 (“the ´111 Patent”) relate to various features of professional mobile radio (“PMR”) communications systems, referred to as critical communications systems or land mobile radio (“LMR”). PMR communications systems are used by public safety personnel such as fire and police departments in emergency situations, as well as in the energy infrastructure industry and for other commercial applications.

To institute IPR, the PTAB is required by statute to find that a petitioner has raised a reasonable likelihood that it will prevail with respect to at least one challenged claim. The PTAB instituted IPR on all challenged claims based on all grounds set forth in Hytera´s petitions.
