Less than a day after the unveiling of OnLive at GDC 2009, Sony filed for a patent called "PS Cloud" with the US Patent Office, outlining it as "entertainment services, namely, providing an online videogame that users may access through the internet".

That's a pretty itchy trigger-finger. I wonder how many people went and parked new domain names as well in the wake of all the OnLive hubbub. The patent also says the service would be made available for handheld devices and home consoles and could also be used for streaming music, ebooks and more. Those OnLive guys definitely did make a splash with their new service.
