Microsoft Corp. 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.
