CHICAGO – May 10, 2019 – Motorola Solutions, Inc. (NYSE: MSI) today announced that the Patent Trial and Appeal Board (“PTAB”) of the United States Patent and Trademark Office (“USPTO”) issued final written decisions in the Inter Partes Reviews of Motorola Solutions’ U.S. Patent Nos. 8,116,284 and 6,591,111, which relate to Motorola Solutions’ time-division multiple access (TDMA) and group radio communication system technology, respectively. The PTAB rejected all validity challenges against U.S. Patent No. 8,116,284 raised by Hytera Communications Corporation Limited (SHE: 002583) (“Hytera”). In addition, the PTAB upheld the validity of a number of the claims of U.S. Patent No. 6,591,111 challenged by Hytera. Both of these patents are asserted against Hytera’s i-Series and older products in Motorola’s patent infringement case pending against Hytera in the Northern District of Illinois. Late last year, the U.S. International Trade Commission also ruled that Hytera’s pre-i Series Digital Mobile Radio (DMR) products infringe four Motorola patents, including U.S. Patent No. 8,116,284. That ruling is now final. 
The two patents enable important functionality and provide Motorola Solutions’ products with highly reliable, secure communications that customers rely on. The functionality provided by these patents is particularly important in emergency and life-threatening situations, including techniques to:
  • Efficiently use DMR channels by allowing devices to temporarily select a different timeslot when the default timeslot is busy, which increases the number of calls that can take place and significantly reduces the amount of time it takes to set up a new call; and
  • Enable efficient group communications between multiple talkgroups, even if those talkgroups use incompatible protocols.
Mark Hacker, general counsel and chief administrative officer of Motorola Solutions, said, “These decisions by the USPTO’s Patent and Trial Appeal Board underscore the strength of our intellectual property and further validate the merits of Motorola Solutions’ global litigation against Hytera to stop its improper and illegal behavior. We remain committed to vigorously pursuing our patent infringement, copyright infringement and trade secret theft lawsuits against Hytera as we continue developing unique, innovative products for our customers around the world.”
Motorola Solutions is awaiting the PTAB’s final written decision in its review of U.S. Patent No. 8,279,991.
