Apple continued its legal tit-for-tat with Nokia over patents by filing its own complaint with the U.S. International Trade Commission, urging the agency to ban import of Nokia handsets. The move is identical to the one Nokia made against Apple with the ITC in December. The two companies have been locked in a back-and-forth legal battle over patents for months, with each side alleging the other has infringed on critical patents. It is unclear whether the ITC will take up either companies' complaint, but a decision likely won't come until next year. Article
