Excess Claims Fees During Reexamination
Note:
Fees apply for adding claims beyond three independent or twenty total during a reexamination proceeding.

Excess claims fees are applicable to excess claims proposed to be added to a patent by their presentation during a reexamination proceeding. See 37 CFR 1.20(c)(3) and (c)(4). Under “former” 35 U.S.C. 41, excess claims fees were included as part of the “application” filing fee under 35 U.S.C. 41(a)(1), and thus did not apply during reexamination proceedings. The Consolidated Appropriations Act does not include the excess claims as part of the “application” filing fee under 35 U.S.C. 41(a)(1), but separately provides for excess claims fees in 35 U.S.C. 41(a)(2) (as being in addition to the filing fee in 35 U.S.C. 41(a)(1)). 35 U.S.C. 41(a)(2) provides that an excess claims fee is due “on filing or on presentation at any other time” (e.g., during a reexamination proceeding) of an independent claim in excess of three or of a claim (whether independent or dependent) in excess of twenty.

  • (B) The 37 CFR 1.20(c)(3) excess independent claims fee for a seventh independent claim is due if the patent owner cancels ten claims, two of which are independent, and adds ten claims, three of which are independent.
  • (C) The 37 CFR 1.20(c)(4) excess total claims fee for a thirty-first claim is due if the patent owner cancels ten claims, two of which are independent, and adds eleven claims, two of which are independent.
  • (D) The 37 CFR 1.20(c)(3) excess independent claims fee for a seventh independent claim and the 37 CFR 1.20(c)(4) excess total claims fee for a thirty-first claim are due if the patent owner cancels ten claims, two of which are independent, and adds eleven claims, three of which are independent.

If the amendment is limited to revising the existing claims, i.e., it does not provide any new claim, there is no claim fee. The excess claims fees apply only to the submission of new, i.e., “excess” claims.

Fee Deficiency Correction Period for Third-Party Reexaminations
Note:
A one-month time period is set in PTOL-475 for correcting fee deficiencies in third-party requested reexaminations.

If, for a response to a non-final Office action, the excess claims fees required by 37 CFR 1.20(c)(3) and (c)(4) are not paid with the presentation of the excess claims, a notice of fee deficiency will be issued as a Notice of Defective Paper In Ex Parte Reexamination. In third-party requested reexaminations, a one-month time period will be set in the form PTOL-475 for correction of the defect, i.e., the fee deficiency. In patent owner requested reexaminations (including reexaminations ordered under 35 U.S.C. 257) or Director ordered reexaminations, a two-month time period will be set in form PTO-2311 for correction of the defect, i.e., the fee deficiency.

In patent owner requested reexaminations (including reexaminations ordered under 35 U.S.C. 257) or Director ordered reexaminations, a two-month time period will be set in form PTO-2311 for correction of the defect, i.e., the fee deficiency. An extension of time to correct the fee deficiency may be requested under 37 CFR 1.550(c). If the unpaid excess claims fees required by 37 CFR 1.20(c)(3) and (c)(4) are not paid within the time period set for response to the Notice, the prosecution of the reexamination proceeding will be terminated under 37 CFR 1.550(e), to effect the “abandonment” set forth in 37 CFR 1.20(c)(5). If the excess claims fees required by 37 CFR 1.20(c)(3) and (c)(4) are not paid with the presentation of the excess claims in a response to a final Office action, the examiner should notify the owner of the fee deficiency in the advisory action.
