A ruling on Eastman Kodak’s patent case against Apple and Research In Motion (RIM) may be delayed until August after the U.S. International Trade Commission sent the issue back to a judge who had earlier ruled against Kodak. The patent at issue relates to camera-phone image previews.

The suit, which aims to block Apple and RIM from importing iPhone and Blackberry phones, was filed by Kodak in January last year. It alleges that Apple and RIM infringed its patents with a feature that allows image previews on their phones. The ITC agreed to investigate the claim in February last year.
