Typical Filing Fees for an Independent InventorThe most common kind of patent filed for is a non-provisional utility patent. There are three basic fees (2012) for utility patents filed for in the United States:
- $625 - $825 for the filing fee with no more than 3 claims, which is non-refundable whether or not a patent is granted. This is the fee to have your application "examined" by the USPTO and your patent application may be rejected.
- $870 for the issue, which is paid after your patent was approved. You pay this fee only if your patent application was approved by the USPTO.
- $565, $1425, $2365 for maintenance fees paid at 3 1/2, 7 1/2, and 11 1/2 years after your patent is granted. These fees maintain your legal protection.
- Additional fees may be required.
Yes, fees for a provisional patent are cheaper (currently $125) but the protection only lasts for one year and then you must file for a regular patent as described above.
