Interference No. 103,197 that the pages which form this exhibit were in existence on November 24, 1987, whether or not Johnson’s testimony also demonstrates that he understood the contents of these pages at that time. Price v. Symsek, 988 F.2d 1187, 1195-96, 26 USPQ2d 1031,1037-38 (Fed. Cir. 1993). Referring to page 1 of the exhibit, the sketch and notations in the upper part of the page corroborate J. Morrison’s testimony that during the meeting he described a conventional fetal monitor having a single EKG lead for measuring the pulse rate. The sketches and notations at the61 bottom part of the page corroborate his testimony that he also brought and demonstrated a conventional non-invasive pulse oximeter system having a clip-on probe for measuring oxygen saturation in a finger, ear, or nose using a visible red LED and an infrared LED for irradiating the tissue and a detector for receiving the transmitted radiation, with the detected infrared radiation intensity representing blood and the detected red radiation intensity representing blood + oxygen. 62 J.
