Some key events in the patent disputes involving Eastman Kodak Co., Apple Inc. and Research In Motion Ltd.:
January 2010: Kodak sues Apple and RIM after failing to negotiate patent-royalty deals. It claims the smartphone makers are infringing its 2001 patent covering technology that enables a camera to preview low-resolution versions of a moving image while recording still images at higher resolutions. The cases were filed in U.S. District Court in Rochester, N.Y., as well as the U.S. International Trade Commission, which oversees trade disputes.
February 2010: The trade commission agrees to investigate Kodak's complaint.
April 2010: In a counterclaim, Apple argues that some Kodak still and video camera products violate two of its patents.
January 2011: Paul Luckern, the commission's chief administrative law judge, rules that Apple and RIM did not violate Kodak's patent.
March 2011: The agency's full six-judge panel agrees to review Luckern's decision.
June 2011: The commission sends the case back to Luckern for further review.
July 2011: While Kodak's claim is pending, the commission rules on Apple's complaint and says Kodak's digital-camera technology doesn't violate Apple's patents.
