Could someone correct me if I'm wrong about the filing of a non-provisional utility fees step by step?
1. I need to pay $95 for Filing + $310 for Search + $125 for Examination (Total $530) to submit my online application.
2. After approval of my application (1 - 3 years), I must pay $870 for utility issuance.
3. After 3.5 years, I must pay $565 for maintaining the patent.
Are these the total fee I need to pay for filing a patent as an individual? Is there any other mandatory fee?
NOTE: Please do not emphasize the necessity of attorney, as it is not the case here.
