In 1607 Galileo Galilei issued from Venice at the press of Tomaso Baglioni Difesa di Galileo Galilei ... contro alle calumnie & imposture di Baldessar Capra. This booklet published the transcript of the trial resulting from the lawsuit that Galileo successfully brought against Baldessar Capra for copying the proportional and military compass that Galileo had invented. It was among the first, if not the very first, record of litigation over an invention, and most certainly the first litigation in the history of computing.
