Current case - Google sued for patent infringement:
One of the two patents with the number 5,425,085 relates to a technique for establishing the cheapest call connection, the other with the number 5,519,769 describes a system for updating a database with call charges to select the cheapest connection. The lawsuit was filed as early as October 2005 and has now come to light through the New York Post newspaper.
