Microsoft sued for alleged theft of IP
Microsoft was sued by Agere for theft of key technology used in Internet telephony. The allegations concern meetings between Agere and Microsoft in 2002 and 2003, where the companies discussed selling Agere's stereophonic acoustic echo cancellation technology to Microsoft. This technology is used to improve the sound of telephone and teleconference communications over the Internet (i.e., VOIP). Just before the agreement was to be signed, Microsoft ended the discussions saying that it made a significant breakthrough in its own, heretofore undisclosed research program, and no longer needed Agere's technology.
