Examination of Application by Limited Issue
Note:
This rule allows examination of an application to focus on a particular issue when the full application is too informal, has multiple claims, misjoins inventions, or relates to perpetual motion.
Some situations exist where examination of an application appears best accomplished by limiting action on the claim thereof to a particular issue. These situations include the following:
  • (A) Where an application is too informal for a complete action on the merits. See MPEP § 702.01;
  • (B) Where there is an undue multiplicity of claims, and there has been no successful telephone request for election of a limited number of claims for full examination. See MPEP § 2173.05(n);
  • (C) Where there is a misjoinder of inventions and there has been no successful telephone request for election. See MPEP §§ 803, 810, and 812.01;
  • (D) Where disclosure is directed to perpetual motion. See Ex parte Payne, 1904 C.D. 42, 108 OG 1049 (Comm’r Pat. 1903). However, in such cases, the best prior art readily available should be cited and its pertinence pointed out without specifically applying it to the claims.

All Other Rejection Grounds Required for Res Judicata

When a rejection is based on res judicata, no prima facie showing for reissue, new matter, or inoperativeness (excluding perpetual motion), all other available grounds of rejection must also be addressed.

On the other hand, a rejection on the grounds of res judicata, no prima facie showing for reissue, new matter, or inoperativeness (not involving perpetual motion) should be accompanied by rejection on all other available grounds.
