March 20 (Bloomberg) -- Samsung Electronics Co. countersued Ericsson AB for patent infringement, claiming it unlawfully used the South Korean phone maker’s technology and breached an agreement.
Asia’s biggest technology company is asking that Ericsson’s lawsuit against it for alleged patent violations be thrown out as the claims are invalid, according to papers filed March 18 in U.S. federal court in Texas.
Ericsson, the world’s largest maker of wireless networking equipment, sued Samsung in November after failing to extend a licensing deal after years of negotiations. The two companies have also filed complaints against each other with the International Trade Commission over alleged patent infringements.
“Over the course of two years of negotiations between the parties, Ericsson has engaged in a pervasive and pernicious pattern of refusing to grant licenses to Samsung on fair, reasonable and non-discriminatory terms,” Samsung said in its filing.
Stockholm-based Ericsson had said in its lawsuit that it offered to extend its previous licensing agreement with Samsung on such terms and the Suwon, South Korea-based company refused.
The case is Ericsson Inc. v Samsung Electronics Co. Ltd. 6:12-00895, U.S. District Court, Eastern District of Texas, Tyler Division.
