system technology designer accusing Microsoft of ripping of its patent for "tiles."
SurfCast, in a complaint filed yesterday in a U.S. District Court in Maine, said Microsoft infringes
one of its four patents — No. 6,724,403 — by "making, using, selling, and offering to sell devices
and software products" covered by SurfCast's patent. That includes mobile devices using the
Windows Phone 7 and Windows Phone 8 operating systems as well as PCs using Windows 8/RT.
