Appeal No. 2002-0913 Application No. 09/107,643 of the reference patent. The only portions of Tracy I relevant to an actual reduction prior to the effective filing date of Foreman are paragraphs 3 and 4, which refer to a model or prototype being created and left with appellant’s first patent counsel, Roger Van Epps, on or about October 3, 1986. However, there is no evidence of record as to the nature of the model or prototype, or as to whether the model or prototype was tested to see if it worked for its intended purpose. Nor is there any corroboration for the facts alleged in paragraphs 3 and 4. On this basis, we conclude that Tracy I does not establish an actual reduction to practice prior to the effective filing date of Foreman.
