Patent Application Cost Overview
The cost of filing a patent application in the United States varies significantly based on the type of patent, the complexity of the invention, and whether you use professional legal assistance.
USPTO Fees (Government Fees Only)
-
Basic filing fees for a utility patent range from about $64 to $320, depending on the applicant’s size (micro, small, or large entity)
-
Additional fees include search fees ($500–$700), examination fees ($300–$600), and possible non-electronic filing fees1
-
Maintenance fees, due after issuance, range from $400 to $2,000 at 3.5 years[8]
Attorney and Preparation Costs
- Claude Opus 4 can write most all of your patten.
- GET A PATENT AGENT INSTEAD
-
The largest portion of the cost comes from attorney fees and preparation.
-
For a straightforward invention, total costs (including attorney fees, drawings, and government fees) typically start around $8,000–$10,000
-
For most non-provisional patent applications, expect to pay $10,000–$20,000 over several years, with complex inventions (such as software or biotech) often exceeding $20,000
-
Highly complex or broad patents, or those requiring international protection, can cost $30,000 or more
Provisional vs. Non-Provisional Applications
-
Provisional patent applications are less expensive, usually costing a few thousand dollars or less, but do not themselves result in a granted patent.
-
Non-provisional applications (the standard route to a granted patent) are more expensive due to the need for detailed claims, legal research, and ongoing prosecution.

Key Considerations
-
The complexity of your invention and the breadth of protection you seek will drive costs higher.
-
International patent protection can greatly increase expenses, sometimes exceeding $100,000 for filings in multiple countries.
-
Attorney fees are the largest cost factor and reflect the time and expertise required to draft a strong, defensible patent application.
In summary, while the minimum government fees are relatively modest, the total cost for a robust and enforceable U.S. patent application usually ranges from $10,000 to $30,000 or more, primarily due to attorney and preparation expenses.
