 2520 Maintenance Fee Amounts [R-01.2024]

 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.
