Launching in the last week, Microsoft’s Windows 8 and Windows Phone platforms are already the subject of legal complaints, after a Portland-based OS development company called SurfCast sued the company for allegedly infringing on its patents with the use of Live Tiles in its desktop, tablet and mobile software.
Update: A Microsoft spokesperson issued The Next Web with the following statement: “We are confident we will prove to the court that these claims are without merit and that Microsoft has created a unique user experience.”
SurfCast filed its lawsuit with the U.S. District Court for the District of Maine on October 30, naming one of its four patents in the complaint. The technologies include patent 6,724,403 (’403): “System and method for simultaneous display of multiple information sources.”
The ’403 patent covers the method of “presenting information from variety of sources on a display device.” It details a graphical user interface that “organizes content from a variety of information sources into grid of tiles each of which can refresh its content independently of the others.”
SurfCast’s ’403 patent
In its complaint, SurfCast continually references Microsoft’s own patent, No. 7,933,632 (’632): “Tile space user interface for mobile devices.” SurfCast alleges four counts where Microsoft’s use of Live Tiles in its software products infringes on the ’403 patent, which was issued April 20, 2004.
“During prosecution of the application that issued as the ’632 patent the Patent Examiner cited the ’403 patent as relevant prior art as part of a Non-Final Rejection dated April 21, 2009,” SurfCast notes.
Microsoft’s ’632 patent
The ’632 patent is similar to the ’403 patent, detailing “systems and methods for providing a user interface mobile devices enable data and services available through mobile device to be represented as a set of tiles maintained a display space.”
On its website, SurfCast provides the following summary of the company:
SurfCast designs Operating System technology and has four issued patents with additional applications pending.
SurfCast designed a new concept referred to as ‘Tiles’.
Tiles can be thought of as dynamically updating icons. A Tile is different from an icon because it can be both selectable and live — containing refreshed content that provides a real-time or near-real-time view of the underlying information.
If you look at how Microsoft’s Live Tiles in Windows 8 and Windows Phone operate, the patent description certainly matches the technology that SurfCast has patented. The company names “Windows Phone, Microsoft Surface with the Windows RT Operating System, Microsoft Windows RT, Microsoft Windows 8, Microsoft Windows 8 Pro, and Microsoft Windows 8 Enterprise Operating System” in its suit.
However, it also says that because Microsoft details ways for developers to create app tiles that can display information on a homescreen, when these apps are submitted to the Windows Store, they are also infringing upon its patent.
Moving forward, SurfCast requests that orders are submitted showing that Microsoft has directly infringed, included the direct infringement and the contributed to the direct infringement of its ’403 patent. Microsoft is also asked to “account and pay to SurfCast all damages caused to SurfCast by reason of Microsoft’s patent infringement.”
Microsoft has its own patent, but as SurfCast points out, it explicitly references the ’403 patent as a case of prior art. We have contacted Microsoft for comment on the lawsuit and will update when we hear back.
