===Microsoft suit===
In 2007, Agere Systems sued [[Microsoft]] for theft of key technology used in Internet telephony.<ref>{{cite news | url=http://www.informationweek.com/news/198800210 | archive-url=https://archive.today/20130126083205/http://www.informationweek.com/news/198800210 | url-status=dead | archive-date=January 26, 2013 | title=Agere Systems Sues Microsoft Over Internet Phone Technology | first=Paul | last=McDougall | work=Information Week | date=2007-04-07 | access-date=2011-05-11 }}</ref><ref>{{cite news | url=http://www.marketwatch.com/story/agere-says-microsoft-lifted-voip-technology | title= Agere says Microsoft lifted VoIP technology | first=John | last=Letzing | work=MarketWatch | date=2007-03-29 | access-date=2011-05-11}}</ref><ref>{{cite news | url=http://www.marketwatch.com/story/bell-labs-legend-haunts-courtroom-tech-rivals | title=Bell Labs legend haunts courtroom tech rivals | first=John | last=Letzing | work=MarketWatch | date=2007-04-09 | access-date=2011-05-11}}</ref> 

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. 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.
