Applicant is required to pay excess claims fees for each claim that is in excess of 3 in independent form or in excess of 20 (whether dependent or independent). Fees for a proper multiple dependent claim are calculated based on the number of claims to which the multiple dependent claim refers (37 CFR 1.75(c)) and a separate fee is also required in each application containing a proper multiple dependent claim. See MPEP § 607. When applicant adds a new excess claim that is in excess of the number of claims that were previously paid for after taking into account claims that have been canceled, applicant must pay the required excess claims fees before the examiner considers the new claim. For example, in an application that contains 6 independent claims and 30 total claims for which the excess claims fees were previously paid, when applicant cancels 10 claims, 2 of which are independent, and adds 11 claims, 3 of which are independent, excess claims fees for a 7th independent claim and a 31st claim are required.
