Microsoft Prevails in Patent Battle– Again

A long-term patent battle between Microsoft and a California- and Singapore-based security software company known as Uniloc has found Microsoft on the winning side… again. The said battle began about six years ago when Uniloc first sued Microsoft for allegedly infringing a patent of a technology that decries piracy by way of an activation key. Microsoft was supposed to have violated the patent by integrating the technology into the Windows XP and Office products’ activation sequences that we all know and love. In short: Microsoft won the original case in 2003, Uniloc appealed and eventually won the appeal in April 2009 after many years of long and drawn out legal proceedings, and Microsoft appealed the appeal and won that appeal just recently, now not having to pay the US$388 million from the last appeal. Oh, and Uniloc already has plans to appeal.
