Facebook is apparently prepared to burn through a lot of cash these days as the social networking site has reportedly purchased patents from IBM (NYSE:IBM) recently and may have made a bid for AOL’s (NYSE:AOL) patent portfolio.Facebook’s bid for the portfolio was outmatched by Microsoft’s (NASDAQ:MSFT) $1.06 billion bid, however.Mark Zuckerberg has full control over how the company spends its cash, which was made very apparent by his decision to pull the $1 billion trigger on Instagram.
