Design Application Fee
Design application fee includes an official fee to be paid with Patent Office and a service fee to be paid to a legal representative (i.e., patent attorney). If one is going through design application procedures from filing to registration without any help of patent attorney, only official fee is needed to be paid. Whereas, if the prosecutions are conducted with the help of a patent attorney, one needs to pay both of the official fee and attorney service fee.

Applicant as an individual or a small-sized entity is exempted from 70% of the official fees. Further, medium-sized entity is exempted from 50% of official fees, and students or handicapped is exempted from 100%.
