Motorola Mobility filed a complaint
“Motorola has innovated and patented throughout every cycle of the telecommunications industry evolution, from Motorola’s invention of the cell phone to its development of premier smartphone products. We have extensively licensed our industry-leading intellectual property portfolio, consisting of tens of thousands of patents in the U.S. and worldwide. After Apple’s late entry into the telecommunications market, we engaged in lengthy negotiations, but Apple has refused to take a license,” stated Kirk Dailey, corporate vice president of intellectual property at Motorola Mobility.
