The U.S. International Trade Commission has decided to review a decision made by a judge in October that cleared Apple of violating four of HTC’s smartphone patents. The ITC is going to revisit one of the four patents, which pertains to “technology for looking up and quickly dialing phone numbers and different techniques for managing power consumption on portable electronic devices.” HTC appealed the October ruling and the ITC has agreed to reexamine the judge’s decision. Due on Monday is another decision from the ITC on whether HTC infringed on Apple patents. If the ITC rules in Apple’s favor on this different set of patents, HTC could be banned from importing some of its smartphones to the U.S.
