Microsoft is heavily invested in unified communications and they have developed a fair amount of proprietary tools and technologies- many of which they hold patents for. They filed a lawsuit against Alcatel-Lucent for infringing on 4 of their unified communications patents, and originally Alcatel-Lucent was found guilty of violating one of the four patents. This week the ITC overturned that ruling and found in favor of Alcatel-Lucent. This is following the April decision by the ITC in a related countersuit that found Microsoft guilty of violating two Alcatel-Lucent patents in which Microsoft was ordered to pay almost $370 million in damages. The war is not over though between these two. Maybe Microsoft should just buy Alcatel-Lucent and then there won’t be any further allegations of patent infringement?
