Kodak said Saturday it would appeal the ruling.
In May, that Apple's iPhone 3G and some RIM BlackBerry devices infringe the Kodak patent, U.S. Patent No. 6,292,218, but also ruled that the patent itself is invalid. In essence, the decision determined that Kodak's claim was invalid.
Kodak, RIM and Apple separately petitioned the ITC for a review of different parts of the decision.
Late Friday, the U.S. ITC affirmed Pender's decision. "The investigation is thus terminated with a finding of no violation," the ITC said in a brief notice.
The ITC said it would offer more details behind its ruling in a forthcoming opinion.
