"Wiko has been infringing Ericsson's intellectual property rights for six years without any license or compensation," the company said in a statement.
"Ericsson has tried to establish a fair, reasonable, and non-discriminatory (FRAND) license agreement with Wiko since May 2013, but has not succeeded."
Wiko did not immediately respond to a request for comment.
Ericsson has an intellectual property portfolio that includes more than 42,000 granted patents worldwide.
