## Text

37 CFR
1.20(e)-(h)
sets the fee amounts for the maintenance fees and the
grace period surcharge. The maintenance fee amounts are subject to adjustment to reflect
fluctuations occurring in the Consumer Price Index pursuant to
35 U.S.C. 41(f)
.
The maintenance fee amounts (
37 CFR 1.20(e)-(h)
) are subject to
a 60% reduction for small entities pursuant to
35 U.S.C. 41(h)
and an 80%
reduction for micro entities. The Maintenance Fee Branch may be contacted or the USPTO
Fee Information website (
www.uspto.gov/Fees
) may be accessed
for the current maintenance fee amounts.
The term of a patent might be shortened, e.g., by a terminal disclaimer.
If a patent will expire part way between the due dates set in
35 U.S.C. 41(b)
,
or between the latest due date and the term set in
35 U.S.C. 154
, it is still required
that the entire maintenance fee amount for the due date be paid. The maintenance fee
amount cannot be prorated to cover only the amount of time past the due date before the
patent expires.
37 CFR
1.366(g)
provides that maintenance fees and surcharges relating
thereto will not be refunded except in accordance with
37 CFR 1.26
and
1.28(a)
. A patentee cannot obtain a refund of a maintenance fee
that was due and payable on the patent. Any duplicate payment will be refunded to the
fee submitter.
