InterDigital Inc. lost an eight-year battle to claim patent royalties on Nokia phones, now made by Microsoft Corp.
The devices don’t infringe patents related to ways that control how mobile phones make calls, the U.S. International Trade Commission said in a notice posted Friday on its website. It rejected InterDigital’s request to block U.S. imports of the Nokia-branded phones. The case was filed in August 2007 before Nokia Oyj sold its handset business to Microsoft.
