Do I qualify for the micro-entity rate for my patent?

An applicant generally qualifies as a micro entity if the applicant and inventors each have gross annual incomes less than three times the median household income for the preceding year (currently $153,051). Higher education institutions may also qualify for micro entity status. There is a form that is filed with the patent to request this rate.

If you qualify a lot of the fees charged by the USPTO can be reduced by 75%.
