Interference No. 103,029 948, 951, 1925 Dec. Comm'r Pats. 245, 251 (D.C. Cir 1925). A satisfactory showing under the rule must include evidence that the party was not negligent in preparing the original statement and the error could not have been avoided by the exercise of due care. See Rivise and Caesar, Interference Law and Practice §100, Vol. I, p. 278 (Michie Co., 1940). In the more recently reported cases, the requirement outlined above has been followed, and the rule and its predecessor have been construed strictly. In fact, the predecessor to 37 CFR § 1.628 (37 CFR § 1.222) has been interpreted to "require a showing demonstrating that the moving party was not negligent in preparing the original preliminary statement and that the error could not have been avoided by the exercise of due care" if the motion were "filed after the preliminary statements were approved and their contents known to the parties."
