“Welch commenced production of the sticks and made his first delivery to Pan American on August 12, 1948. That date marked the beginning of public use of the dipstick. Grindle was soon thereafter assigned to other duties and took no further interest in the dipstick. Thereafter, on August 17, 1949, Welch filed for a patent on the dipstick swearing that he was the true inventor.”
