Europe’s second highest court has rejected Cisco’s challenge of Microsoft’s Skype acquisition. The European Commission approved the $8.5 billion deal in 2011, but Cisco sought to strip the EU approval almost a year later. Cisco argued at a hearing earlier this year that Microsoft’s acquisition of Skype created a monopoly, and that conditions should have been placed on the deal. Microsoft has since integrated its Lync communications service into the Skype platform to produce a proprietary system.
