How to Use This Tool
Select your entity type (Large, Small, or Micro) as defined by the USPTO. Choose the type of patent application you are filing. Enter the number of claims and drawing sheets for your application. Click the Calculate Fee button to see a detailed breakdown of estimated fees. Use the Reset button to clear all fields and start over.
Formula and Logic
This tool uses the current USPTO fee schedules for utility, design, and plant patents. The calculation includes the base filing fee, search fee, examination fee, and any applicable excess claim fees (for claims beyond 20). Drawing sheet fees are calculated per sheet. Entity size discounts are applied automatically. All fees are based on publicly available USPTO data and are subject to change.
Practical Notes
- Fee schedules are updated periodically by the USPTO; always verify current fees on the official USPTO website before filing.
- Small entity status requires meeting specific criteria (e.g., not exceeding 500 employees, not being obligated to assign rights to a non-small entity).
- Micro entity status has additional income and education requirements; consult a patent attorney to confirm eligibility.
- This tool provides estimates only and does not constitute legal advice. Filing fees are non-refundable.
- Consider additional costs such as attorney fees, drawing preparation, and maintenance fees after allowance.
Why This Tool Is Useful
This estimator helps individuals and small businesses budget for patent filing costs upfront, avoiding surprises during the application process. It provides a clear breakdown of each fee component, making it easier to understand where the money goes. By comparing entity types, users can identify potential savings opportunities. The tool supports informed decision-making when planning intellectual property investments.
Frequently Asked Questions

The tool automatically calculates excess claim fees based on the USPTO rate per additional claim. Ensure your claim count is accurate to avoid underestimating costs.
Can I use this tool for international patent filings?
No, this tool is specific to USPTO filings. International applications (e.g., PCT, EP) have different fee structures and should be estimated using jurisdiction-specific tools.
Are the fees guaranteed to be accurate?
No, fees are estimates based on current USPTO schedules and may change. Always confirm with the USPTO or a qualified patent attorney before filing.
Additional Guidance
For complex applications, consider consulting a registered patent attorney or agent. They can help with claim drafting, prior art searches, and navigating USPTO procedures. Keep records of all fee payments and correspondence. If you qualify for fee reductions, ensure proper documentation is submitted with your application. Regularly check the USPTO website for updates to fee schedules and entity requirements.
