Microsoft's win on keyboard patents reversed

Microsoft faces a trial over patent infringement charges related to its ergonomic keyboards after a federal appeals court on Tuesday reversed a lower court's decision that invalidated the patents.

TypeRight Keyboard Corp. sued Microsoft in July 1998, claiming that Microsoft's ergonomic keyboards violated its patents. The Microsoft Natural keyboards feature V-shaped designs with keys in separate clusters for the left and right hands and have a large wrist rest.

Microsoft in June 2000 won a motion to invalidate the patents. The company argued that the concept of ergonomic keyboards predated TypeRight's patents. Evidence that was presented consisted of an undated document from a German company, Marquardt GmbH, and testimony from paid fact witnesses.
