The MOI was witnessed by Paul A. Adair on December 2, 1987 (OR p.41) and receipt of the MOI was acknowledged by Mr. Stein in a letter to Ms. Oates dated December 15, 1987 (OR p.43-44; OX-4). Stein has testified that he remembers having his secretary prepare the December 15, 1987, letter to Ms. Oates acknowledging receipt of the MOI by the patent department from the information contained in the MOI using a PPG form (OX-12) specifically designated for that purpose (OR p.161-170). The MOI states that the invention was first described in writing in "Notebook 6748 7-31-85". Notebook 6748 is Ms. Oates' notebook (OX-1) and it included an account of her work from July 18, 1985, through June 2, 1986.
