In a preliminary ruling, the US International Trade Commission has again found that Apple's iPhone did not infringe on a Motorola patent regarding proximity sensors, another win for the Cupertino company in a string of almost-exclusively favorable ITC rulings. Judge Thomas Pender ruled again that the Motorola patent, now owned by Google, is invalid. The ruling came as a part of an appeal against his earlier August decision, which covered both the sensor patent and several 3G-related ones. The ruling is preliminary, and will be reviewed by a full panel.
