Case Facts & Court Holding
Key Facts & Case Background
Appellants Klopfenstein and Brent applied for a patent on October 30, 2000, for methods of preparing foods with extruded soy cotyledon fiber to lower cholesterol. In October 1998, more than one year prior to the application, appellants and a colleague presented a 14-slide presentation (the “Liu reference”) detailing the invention at an American Association of Cereal Chemists (AACC) meeting. The printed slides were pasted onto poster boards and displayed continuously for two and a half days. The same presentation was displayed for less than a day at Kansas State University’s Agriculture Experiment Station (AES) in November 1998. Both parties agreed the Liu reference disclosed every limitation of the invention. No copies were disseminated, and the presentation was not catalogued or indexed. No disclaimers prohibited note-taking or copying. The PTO rejected the application, finding the Liu reference was a “printed publication” under 35 U.S.C. § 102(b), anticipating the claims. The Board of Patent Appeals and Interferences affirmed, and appellants appealed.
