Microsoft has filed a lawsuit against Lucent Technologies, asking that a court nullify a number of Lucent patents covering technology in some of the software giant's products. The suit, filed on Tuesday in a federal court in San Diego, is the latest in struggle that has simmered over the past year over audio and video coding and other technologies patented by Lucent's research arm, Bell Laboratories. The Wall Street Journal first reported this story on Friday, noting that Microsoft was seeking to invalidate 13 Lucent patents.
