TMEP § 819.05(b)
If the insufficient information fee or free-form text ID fee is paid at filing for each class, the examining attorney will not require the same fee for those classes even if additional deficiencies are found during examination.
Example: The application is for three classes. The applicant only uses entries from the ID Manual within the electronic form but does not submit a verified statement. The applicant pays the insufficient information fee for each class in the application at filing (i.e., for three classes). Even if the examining attorney later determines that the application does not meet a different base application requirement under 37 C.F.R. §2.22(a)(1)-(19) (see TMEP §§819.02-819.02(n)), the examining attorney must not require the insufficient information fee for these same three classes. However, if the applicant later amends the application to add one or more classes, the applicant must pay the filing fee and insufficient information fee for each added class.
Example: The application is for two classes. The applicant elects to use free-form text ID entries and entries from the ID Manual within the electronic form, but otherwise meets the base application requirements. The applicant pays the free-form text ID fee for each class in the application at the time of filing (i.e., for two classes). Even if the examining attorney later discovers misuse of the fill-in-the-blank field for any of the ID Manual entries in the application, the examining attorney must not require the free-form text ID fee for these same two classes. However, if the applicant later amends the application to add one or more classes, the applicant must pay the filing fee and free-form text ID fee for each added class.
