Hytera files patent infringement suit against Motorola Solutions
Hytera Communications Corporation Limited filed a lawsuit against Motorola Solutions on 28 August in the US District Court for the Northern District of Ohio. It claims that that Motorola Solutions is infringing Hytera's U.S. Patent No. 9,183,846, which covers its sound adjustment control technology
Hytera’s '846 patent is its method for adjusting sound volume in response to background or ambient noise, allowing a radio operator to hear and speak over it. The device obtains the current level of ambient noise, receives an instruction, and adjusts sound output. If ambient noise is high, the volume adjustment is greater at higher (treble) frequencies. Hytera's complaint asserts that Motorola Solutions unlawfully misappropriates Hytera’s patented technology for sound adjustment, incorporating it into its MOTOTRBO portable radios. Hytera is represented in this action by Todd Tucker of Cleveland, Ohio-based law firm Calfee, Halter & Griswold LLP.
"Hytera has changed the landscape of the PMR business with its constant innovations, especially after its launch of a digital product line in 2010," said Tom Wineland, director of sales for Hytera Communications America (West), Inc. in Irvine, California. "Our patented sound adjustment functionality is one of the many innovations that Hytera has incorporated into our digital products, and users in markets around the world have embraced this feature."
