Preliminary Amendment to Correct Informalities Promptly
Note:
Applicants should submit a preliminary amendment within 3 months of filing to correct obvious informalities in the application, ensuring adequate disclosure and claim conformity.

It is to applicant’s advantage to file the application with an adequate disclosure and with claims which conform to the U.S. Patent and Trademark Office usages and requirements. This should be done whenever possible. If, however, due to the pressure of a Convention deadline or other reasons, this is not possible, applicants are urged to submit promptly, preferably within 3 months after filing, a preliminary amendment which corrects the obvious informalities. The informalities should be corrected to the extent that the disclosure is readily understood and the claims to be initially examined are in proper form, particularly as to dependency, and otherwise clearly define the invention. “New matter” must be excluded from these amendments since preliminary amendments filed after the filing date of the application do not enjoy original disclosure status. See MPEP § 608.04(b).

Examiner Must Search Invention When Terms Are Incongruous
Note:
When the terms used to describe an invention do not align with related art, the examiner must conduct a reasonable search based on the disclosure.

Whenever, upon examination, it is found that the terms or phrases or modes of characterization used to describe the invention are not sufficiently consonant with the art to which the invention pertains, or with which it is most nearly connected, to enable the examiner to make the examination specified in 37 CFR 1.104, the examiner should make a reasonable search of the invention so far as it can be understood from the disclosure. The action of the examiner may be limited to a citation of what appears to be the most pertinent prior art found and a request that applicant correlate the terminology of the specification with art-accepted terminology before further action is made.

Requirement for Informal Disclosure Resolution
Note:
The rule requires the examiner to make a reasonable search, list informalities, and require specification revisions when an application's disclosure is insufficient or informal.
When an application is taken up for examination and it is then discovered to be impractical to give a complete action on the merits because of an informal or insufficient disclosure, the following procedure may be followed:
  • (A) A reasonable search should be made of the invention so far as it can be understood from the disclosure, objects of invention and claims and any apparently pertinent art cited. In the rare case in which the disclosure is so incomprehensible as to preclude a reasonable search, the Office action should clearly inform applicant that no search was made;
  • (B) Any form that lists informalities and any additional formal requirements to be made should be included in the first Office action (see MPEP § 707.07(a));
  • (C) A requirement should be made that the specification be revised to conform to idiomatic English and United States patent practice;
  • (D) The claims should be rejected as failing to define the invention in the manner required by 35 U.S.C. 112 if they are informal. A blanket rejection is usually sufficient.

Examiner Form Paragraphs

Examiner form paragraphs are standard language that you might see in an Office Action or communication from the USPTO. Examiners have latitude to change the form paragraphs, but you will often see this exact language.

¶ 7.01 ¶ 7.01 Use of Unconventional Terminology, Cannot Be Examined

A preliminary examination of this application reveals that it includes terminology which is so different from that which is generally accepted in the art to which this invention pertains that a proper search of the prior art cannot be made. For example: [1]

Applicant is required to provide a clarification of these matters or correlation with art-accepted terminology so that a proper comparison with the prior art can be made. Applicant should be careful not to introduce any new matter into the disclosure (i.e., matter which is not supported by the disclosure as originally filed).

A shortened statutory period for reply to this action is set to expire TWO MONTHS from the mailing date of this letter.

¶ 7.02 ¶ 7.02 Disclosure Is Incomprehensible

The disclosure is objected to under 37 CFR 1.71 , as being so incomprehensible as to preclude a reasonable search of the prior art by the examiner. For example, the following items are not understood: [1]

Applicant is required to submit an amendment which clarifies the disclosure so that the examiner may make a proper comparison of the invention with the prior art.

Applicant should be careful not to introduce any new matter into the disclosure ( i.e., matter which is not supported by the disclosure as originally filed).

A shortened statutory period for reply to this action is set to expire TWO MONTHS from the mailing date of this letter.
