- May 11, 2019-

On May 10, 2019, Motorola Solution announced today that the US Patent and Trademark Office (USPTO) Patent Trial and Appeals Board (PTAB) issued the final written decision. The parties evaluate US Patent Nos. 8,116,284 and 6,591,111 to Motorola Solutions, which relate to Motorola Solutions' Time Division Multiple Access (TDMA) and group radio communication system technologies, respectively. PTAB rejected all doubts about the validity of US Patent No. 8,116,284 filed by Hytera. In addition, PTAB maintains the validity of many of the claims of the U.S. Patent No. 6,591,111 to Hytera. Both of these patents target Hytera's i-series products and products in Motorola's patent infringement case.


At the end of last year, the US International Trade Commission also ruled that Hytera's i-series digital mobile radio (DMR) products infringed Motorola's four patents, including US Patent No. 8,116,284.

 

These two patents fulfill important functions and provide Motorola Solutions products with the highly reliable and secure communications that customers rely on. The features provided by these patents are particularly important in emergency and life-threatening situations, including the following technologies:

 

By effectively allowing the device to temporarily select different time slots when the default time slot is busy, the DMR channel is effectively used, which increases the number of calls that can occur and significantly reduces the time required to establish a new call; even if these call groups are not compatible The protocol also enables efficient group communication between multiple talk groups.

Advantages to prevent inappropriate and illegal behavior. We continue to file lawsuits against Hytera's patent infringement, copyright infringement and trade secret theft, as we continue to develop unique and innovative products for our customers."
