By Stephen Nellis and Sayanti Chakraborty (Reuters) - Qualcomm Inc won a partial stay against the enforcement of a sweeping antitrust ruling in a lawsuit brought by the Federal Trade Commission (FTC), according to a court filing on Friday. The company on May 21 lost in an antitrust lawsuit and has been fighting to have the ruling put on hold while it pursued an appeal. The San Diego, California-based company argued that letting the ruling stand could upend its talks with phone makers over chips for 5G, the next generation of wireless data networks.
