RE: ONE - June 2010 - July 2010 The Patent and Trademark Office had upheld 25 of the claims that Citrix challenged when the Canadian company 01 Communique Laboratory Inc sued Citrix and its cloudy GoToMyPC product for patent infringement in early 2006. That gives Communique the right to assert 24 claims as infringed in all and GoToMeeting is also liable.
