Motorola Solutions Inc. asked a German court April 18 to order China’s Hytera Communications Corp. to stop selling two-way wireless communication devices that allegedly infringe its patented technology that helps people have simultaneous conversations on a single radio frequency.

In two complaints filed at the Regional Court in Düsseldorf, Germany, Motorola alleged that Shenzhen, China-based Hytera and its German subsidiary, Hytera Mobilfunk GmbH of Bad Munder, infringed European Patent No. EP 2 342 851 B1 on “pseudo-trunking” digital mobile technology.

Chicago-based Motorola also sought damages and the recall and destruction of alleged infringing products, it said in a statement. Hytera didn’t immediately respond to a request for comment.

The complaint comes on the heels of two other legal actions taken by Motorola over two-way radio technology.

Motorola filed two complaints in a U.S. district court against Hytera March 14, alleging that the Chinese company illegally obtained trade secrets and infringed patents related to radio technology used in applications such as emergency response communications ( Motorola Solutions Inc. v. Hytera Communications Corp. , N.D. Ill., No. 17-1972, complaint filed 3/14/17 ).

Two weeks later, Motorola asked the U.S. International Trade Commission to ban imports of two-way radios made by Hytera ( Certain Two-Way Radio Equipment and Systems, Related Software, and Components Thereof , USITC, DN 3211, request for investigation 3/29/17 ).
