PORTLAND (AP) — A small local technology company has filed a patent infringement lawsuit against Microsoft over elements included in Windows 8.

SurfCast Inc., based in Portland, filed the complaint Tuesday in U.S. District Court asking for unspecified damages.

The lawsuit claims Redmond, Wash.-based Microsoft Corp. is using elements known as live tiles, rectangular icons linked to websites, apps and other items. Surf- Cast says it developed the tiles, referred to on its website as “dynamically updating icons” containing refreshed real-time content, in the 1990s.

Microsoft is using the tiles technology on operating systems including the recently launched Windows 8, found on personal computers, phones, tablets and other devices, the lawsuit claims.
