Sony Corp has filed a patent infringement complaint seeking to block LG Electronics Inc from shipping smartphones such as its Rumor 2 model to the United States.

In a filing late Wednesday with the U.S. International Trade Commission, Sony said LG violated U.S. trade rules by importing mobile phones and modems that infringed Sony patents.

Sony said LG also infringed patents of some of its licensees, including its Sony Ericsson joint venture, Samsung and Nokia.
