The name of each applicant must include the family name, and at least one given name without abbreviation together with any other given name or initial. (If the applicant is not an inventor, this information also includes the applicant’s authority (pre-AIA 37 CFR 1.42, 1.43, and 1.47) to apply for the patent on behalf of the inventor. The “mailing address” is the address where applicant customarily receives mail.

Correspondence information includes the correspondence address, which may be indicated by reference to a customer number, to which correspondence is to be directed (when dealing with pre-AIA 37 CFR 1.33(a)).

Application information includes the title of the invention, a suggested classification by class and subclass, the Technology Center (TC) to which the subject matter of the invention is assigned, the total number of drawing sheets, a suggested drawing figure for publication (in a nonprovisional application), any docket number assigned to the application, and the type of application (e.g., utility, plant, design, reissue, provisional).
