Narrative Opinion Summary
This case involves Robotic Vision Systems, Inc.'s appeal against a decision from the United States District Court for the Central District of California, which invalidated claim 1 of its patent under 35 U.S.C. § 102(b) due to the on-sale bar. The patent pertains to a method for scanning integrated circuits in trays, enhancing efficiency. The district court initially found the invention was sold before the critical date of June 24, 1991, and failed to disclose the best mode. On appeal, the Federal Circuit affirmed the invalidity based on the on-sale provision, focusing on whether the invention was ready for patenting before the critical date. The court found the invention was sufficiently disclosed to enable practice by a skilled person, dismissing the inventor's skepticism as irrelevant under the Pfaff standard. The court concluded the invention was ready for patenting before the critical date, confirming the patent's invalidity. The cross-appeal on the best mode issue was rendered moot. Hence, the Federal Circuit upheld the district court's decision, maintaining the invalidation of the patent claim due to the on-sale bar.
