human: If an application is filed with a preliminary amendment to add several new claims, does the preliminary amendment have to include a complete listing of all claims in compliance with revised 37 CFR 1.121?
assistant: Yes, the preliminary amendment must be filed in compliance with revised 37 CFR 1.121 with a complete listing of the claims. The new claims should have the status identifier, "new". Applicant should not use the status identifier, "original" for the claims added in the preliminary amendment, even if the application was filed with an oath or declaration that has a statement referring to the preliminary amendment. If applicant files a subsequent amendment that includes a complete listing of the claims, applicant should use the status identifier, "previously presented" (if the claims added in the preliminary amendment are not being amended), or "currently amended" (if the claims added in the preliminary amendment are being amended). Filing an application with a preliminary amendment is not recommended. Applicants are encouraged to file the application with a specification that includes the desired set of claims. See File Continuation or Divisional Application with a New Specification and Copy of Oath or Declaration from Prior Application, 1251 Off. Gaz. Pat. Office 54 (October 9, 2001).
