Comments and footnotes

The calculator is intended for information purposes only and does not constitute legal or professional advice. While we attempt to keep fee amounts updated, fees change regularly, and due care should be taken when relying on the calculated figures.

This estimator includes only official fees payable to patent offices. It does not include professional fees charged by patent attorneys or agents.

Significant search fee reductions of 60% are available to small entities and 80% for micro entities where the USPTO is the International Search Authority. However, you should be aware of the eligibility criteria and risks involved in making these elections. For more information see our article on USPTO fee reductions, or for advice specific to your circumstances please get in touch with our team.
