One of the biggest names in peer to peer technology is Skype. In 2008, Skype settled with Mangosoft Technologies in a patent infringement case over a patent apparently related to “dynamic directory service”. Mangosoft’s victory in the case wasn’t enough to keep the company thriving and in May, Mango Capital announced that their subsidiary, MangoSoft Intellectual Property, Inc., sold all of its patent rights for $3.2 million.
While Google used peer-to-peer technology in GMail video, the company blogged a couple of days ago that that video communication service would be replaced with Google Hangouts and no longer rely upon peer-to-peer technology.
Google was assigned 9 granted patents and 4 pending patents from Mangosoft Intellectual Property Inc., as noted in an assignment executed on May 1, 2012 and recorded on July 31, 2012. Among the patent filings is a granted patent and 2 pending patents titled “Dynamic Directory Service.” This directory service “maintains a directory in which is stored both (1) directory information and (2) the physical layout of the directory itself” over the network itself rather than in a centralized location.
