What is the required fee for filing an appellant brief in inter partes reexamination?

A fee is required when filing an appellant brief in an inter partes reexamination. The MPEP states:

“A fee as set forth in 37 CFR 41.20(b)(2) is required when the appellant brief is filed for the first time in a particular reexamination proceeding, 35 U.S.C. 41(a).”

It’s important to note that:

• The fee is only required for the first filing of an appellant brief in a particular reexamination proceeding.
• The fee amount is specified in 37 CFR 41.20(b)(2).
• Failure to pay the required fee may result in dismissal of the appeal.

Always check the current fee schedule on the USPTO website, as fee amounts may be subject to change.
