The US International Trade Commission has ruled that a patent involved in Kodak's lawsuit against Apple and Research in Motion is invalid, according to AppleInsider. In particular an administrative law judge has quashed the 6,292,218 patent, Method for Live View Display and Digital Camera Using Same, on the basis of claim 15 in the document. Kodak will reportedly appeal the decision to the full commission, a necessary step if it intends to continue suing Apple and RIM for infringing the patent.
