The application must include the applicant’s name and domicile address. 37 C.F.R. §2.22(a)(1); In re Chestek PLLC, 92 F.4th 1105, 1113 (Fed. Cir. 2024) (domicile address requirement affirmed). See TMEP §601.01 and §803.05(a) for information on what constitutes an applicant’s domicile address. The insufficient information fee is required if this information is omitted. 37 C.F.R. §2.22(b).

If the application includes this information, no insufficient information fee will be required if the application is amended to clarify the information or to correct an inadvertent error. For example, if applicant’s domicile address is incorrectly identified as a post-office box or "care of" address, the insufficient information fee will not be required to amend the application to clarify or correct the domicile address.
