Encinitas inventor William Louis has been fighting Microsoft Corp. since 1998 over patents for ergonomic keyboards – with very little success. Yesterday, he finally had something to smile about. A federal appeals court resurrected Louis' long-running federal lawsuit accusing the software company of patent infringement. In the decision by the U.S. Court of Appeals for the Federal Circuit, the court said a U.S. District Court judge in San Diego made a mistake when she ruled that patents held by TypeRight Keyboard Corp. for V-shaped keyboards with wrist rests were invalid. Louis co-founded TypeRight in the early '90s.
