I stumbled ona great post from the Fed Cir Blog detailing “every post-Pfaff decision by the Fed Cir that analyzes the on-sale bar.”
In the Pfaff case (PFAFF V. WELLS ELECTRONICS, INC. (97-1130) 525 U.S. 55 (1998), 124 F.3d 1429, affirmed), the Supreme Court held that the on-sale bar applies when two conditions are satisfied before the critical date: (1) the product must be the subject of a commercial offer for sale; and (2) the invention must be ready for patenting (reduction to practice before the critical date or proof that prior to the critical date the inventor had prepared drawings or other descriptions of the invention that were sufficiently specific to enable a person skilled in the art to practice the invention).
Great list!!!!
