Sunnyvale, Calif. — Palm announced today it settled a nine-year-old patent infringement lawsuit filed by Xerox.

Palm will pay Xerox $22.5 million for a license for three Xerox patents to settle the case. Xerox claimed that the handwriting-recognition technology marketed as Graffiti and formerly used in Palm OS devices infringed on a Xerox patent known as the Unistrokes patent. The case was originally filed in April 1997 against a predecessor to Palm.
