Facebook Purchases 650 AOL Patents From Microsoft

eldavojohn writes "Not two weeks after Microsoft purchased 925 patents and patent applications plus licenses to AOL's portfolio for $1 billion, Facebook has now acquired 650 of said patents and patent applications for $550 million to which Microsoft retains a license. So, was Microsoft's $450 million worth it? According to their press release: 'Upon closing of this transaction with Facebook, Microsoft will retain ownership of approximately 275 AOL patents and applications; a license to the approximately 650 AOL patents and applications that will now be owned by Facebook; and a license to approximately 300 patents that AOL did not sell in its auction.' Will the patent-go-round continue, or has Facebook loaded up for a good old-fashion Mexican standoff?"
