ITC Says Apple Didn't Infringe Three Motorola Patents

The country's top trade agency handed Apple a mixed ruling in its dispute with Google-owned Motorola Mobility over patents covering 3G wireless technology. The U.S. International Trade Commission ruled that Apple did not violate three Motorola patents, including one that a judge had found the company to be infringing. But the agency sent a fourth patent -- which the judge had initially said had not been infringed -- back to the judge to reconsider.
