After Microsoft acquired Skype, we looked at a Microsoft patent called "Legal Intercept" meant for monitoring and recording VoIP communications. At that time, there were questions about if Microsoft would ruin Skype by making a backdoor for easy spy and pry government and law enforcement access. But a California-based company called VoIP-Pal already had such a surveillance patent that is meant to "allow government agencies to 'silently record' VoIP communications."
The Microsoft patent was filed in December 2009, but a company called Digifonica (International) Limited had filed a similar wiretapping VoIP patent in 2007. Then, in May 2012, VoIP-Pal attained five VoIP patents from the acquisition of Digifonica Gibraltar. One of the five patents is called "Lawful Intercept" and is meant for "intercepting VoIP and other data communications." (more)
