Abstract
The Supreme Court established a two-part test for determining when an invention is "on sale" under 35 U.S.C. §102(b) in Pfaff v. Wells Electronics, Inc. For the on-sale bar to be triggered, the invention must be "ready for patenting" and subject of a "commercial offer for sale." In Minnesota Mining & Manufacturing v. Chemque, Inc., the Federal Circuit expounded on what constitutes a commercial offer for sale. This iBrief explores what is considered a "commercial offer for sale."
