Remember the heady days of August 2007, when the iPhone had barely reached store shelves and the Nokia N95 was all the rage? The US International Trade Commission sure does. After reviewing an 8-year-long case, the ITC has ruled that Nokia's phones (now Microsoft's) don't infringe on InterDigital patents covering 3G cellular technology. The decision eliminates the possibility of an import ban that would have prevented Microsoft from selling many of its phones in the US, including modern day Lumias. Things very nearly didn't go the company's way -- a judge had ruled in April that Microsoft was using InterDigital's patents, which would have forced the folks in Redmond to pay up.
