Microsoft sued over use of live tiles in Windows

Microsoft has been slapped with a patent infringement lawsuit over its use of dynamic “live” tile icons in Windows, including in the newly launched Windows 8 OS for PCs and tablets and in the Windows Phone 8 OS for smartphones.

SurfCast, based in Portland, Maine, filed its lawsuit on Tuesday in the U.S. District Court for the District of Maine, and is asking for Microsoft to pay an undetermined amount of money in damages and attorneys’ fees.

At issue is U.S. Patent 6,724,403, titled “System and Method for Simultaneous Display of Multiple Information Sources,” which SurfCast was awarded in 2004.

SurfCast takes issue with Windows’ use of live tiles, which are rectangular or square icons in the Start screen of new Windows versions that provide links to applications, websites, contacts and other elements. SurfCast describes itself on its website as a designer of OS technology. It claims to have developed the live tile technology in the 1990s.

In a statement, Microsoft said it was “confident” it would prove in court that SurfCast's claims are without merit and that Microsoft has created a “unique user experience.”
