Asserting a patent on computerized recognition of handwriting

Xerox Corporation called on Finnegan after a district court found that 3Com/Palm’s line of personal digital assistants (commonly called “Palm Pilots”) did not infringe its patent. We secured a reversal of the district court’s claim construction, which led to a finding of infringement and entry of judgment for Xerox on remand. In a second appeal, we succeeded in obtaining an affirmance of the infringement finding.
