InterDigital Loses ITC Patent Case Against Microsoft, ZTE

InterDigital Inc. lost its patent case against Nokia Oyj and ZTE Corp. at the U.S. International Trade Commission, dealing the phone-chip researcher another blow in its efforts to create a new royalty stream. InterDigital pledged to appeal.

Nokia phones, now made by Microsoft Corp., and devices by ZTE didn’t violate InterDigital patent rights, the ITC said in a notice today on its website. The commission upheld, with modifications, June findings from a trade judge who said that Nokia didn’t infringe one patent and that ZTE didn’t infringe that patent or two others.
