Case Brief Summary & Legal Analysis
tl;dr: The court affirmed the PTO’s denial of a patent, finding a prior slide presentation displayed at conferences constituted a “printed publication” under 35 U.S.C. § 102(b), thus barring patentability due to lack of novelty.
Legal Significance: This case clarifies that “public accessibility” is the touchstone for determining if a reference is a “printed publication,” even without distribution or indexing, and introduces factors for analyzing temporarily displayed materials.
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.
