If filing after the payment of the issue fee:

  • The IDS will not be considered, it is just placed in application file.
  • The options at this point are:
    • To withdraw the application from issue so the information may be considered in a continuing application under 37 C.F.R. 1.53(b).
      • In this case, the entire IDS will need to be resubmitted.
    • To withdraw application from issue so a CPA under 37 C.F.R. 1.53(D) may be filed even though the issue fee was already paid.
      • In this case, the entire IDS will not need to be resubmitted.
