High Quality Content by WIKIPEDIA articles! Pfaff v. Wells Electronics, Inc., 525 U.S. 55 (1998), was a decision by the Supreme Court of the United States that determined what constituted being "on sale" for the purposes of barring the grant of a patent for an invention.In November 1980, the plaintiff, engineer Wayne Pfaff, was asked by Texas Instruments to design for them a socket for the mounting and removal of semiconductor chip carriers. Pfaff proceeded to draw designs for the socket, which he showed to Texas Instruments in March 1981. On April 8, 1981, Texas Instruments provided a written purchase order to buy over 30,000 of the sockets. The sockets were not actually built, however, until July 1981.
