Kodak began mining its patent portfolio for license revenue in 2008. In January 2010, it sued Apple and RIM, saying that smartphone makers infringed its patent for technology that lets a camera preview low-resolution versions of a moving image while recording still images at higher resolutions.But by July 2011, it was trying to sell its 1,100 digital imaging patents. Analysts initially thought the portfolio could fetch between $2 billion and $3 billion. But Kodak struggled to find a buyer. The 12 licensees for Kodak's imaging patents were organized by Intellectual Ventures and RPX Corp. Kodak spokesman Christopher Veronda said each licensee will pay a portion of the total cost and then have access to all the patents. The deal also includes an agreement to settle patent-related litigation. The sale represents "another major milestone toward successful emergence" from bankruptcy, said Antonio M. Perez, Kodak's chairman and CEO, in a statement. "Our progress has accelerated over the past several weeks as we prepare to emerge as a strong, sustainable company." Kodak will keep ownership of about 9,600 patents, focused mostly on commercial imaging and printing technologies.
