1606.13(a) Correcting Deficiencies in §9 Renewal Applications Filed Within the Year Before the Expiration Date of the Registration
If the renewal application is filed within one year before the expiration date of the registration, deficiencies may be corrected, after notification from the Office, before the expiration date without paying a deficiency surcharge, or after the expiration date with payment of the deficiency surcharge required by §9(a) of the Act. 37 C.F.R. §2.185(a)(1).
Any deficiency must be cured within the set period for response to the Office action, i.e., within six months of the issuance date of the action, or before the expiration date of the registration, whichever is later. If no response is filed within this time period, the registration will expire, unless time remains in the grace period. If time remains in the grace period, the registrant may file a complete new renewal application, with a new fee. 37 C.F.R. §2.184(b); see TMEP §1606.12.
