MPEP § fp14.35
The previously paid disclaimer fee as set forth in 37 CFR 1.20(d) can be applied when submitting a replacement or supplemental terminal disclaimer. If, however, the disclaimer fee set forth in 37 CFR 1.20(d) has been increased since the fee was previously paid, then applicant must pay the difference between the increased fee and the amount previously paid.
1. This form paragraph can be used to notify an applicant that the previously submitted disclaimer fee can be applied when a replacement or supplemental terminal disclaimer is submitted.
2. Use form paragraph 14.35.01 for providing notification to patent owner, rather than an applicant.
