Ericsson has sued smartphone maker Wiko, in the regional courts of Düsseldorf and Mannheim in Germany, for infringement of patents essential for 2G, 3G and 4G cellular technology, as well as implementation patents.
Gustav Brismark, chief intellectual property officer at Ericsson, said: “Global sharing of technology and open standards are the force behind the smartphone revolution and have allowed new entrants, such as Wiko, to quickly build successful businesses. This ICT eco-system only works, however, if all market players respect the basic rules of FRAND licensing. It is unfair for Wiko to benefit from our substantial R&D investment without paying a reasonable licence fee for our patented technology.
"Our ambition has always been to reach a mutually fair and reasonable licence agreement with Wiko, just as we do with all of our licensees.”
IAM blog further reports that Brismark also claimed that with licensing negotiations between the two sides having begun in 2013, Wiko had adopted a strategy of delay rather than paying for a licence.
Founded in 2011, Wiko is headquartered in France but is reported to be majority owned by Chinese business Tinno Mobile.
The news comes as the patent battle between Apple and Qualcomm continues.
