HTC and Qualcomm are reworking a radio chip for the HTC One smartphone in order to avoid a U.S. ban on imports of patent-infringing technology, according to a Wall Street Journal report. The U.S. International Trade Commission (ITC) made a preliminary ruling last week that Taiwan's HTC had infringed on two Nokia patents. The infringed patents cover a method for receiving and transmitting radio signals, and a method for eliminating unwanted signals.
