Are USPTO API calls free?

Yes, access to the USPTO's developer APIs for patent and trademark data is free. However, registration on the developer portal is required, and API usage may be subject to rate limits to ensure fair access and system stability.

What is a 'micro entity' for USPTO fee purposes?

A micro entity is an applicant who meets specific gross income requirements, has not been named as an inventor on more than four previously filed patent applications, and meets the small entity criteria. Micro entities pay 25% of the large entity fees.

How often do I pay patent maintenance fees?

Patent maintenance fees for utility patents are due at 3.5 years, 7.5 years, and 11.5 years after the patent is issued. Failure to pay these fees will result in the patent expiring prematurely.

Do trademark applications have renewal fees?

Yes, trademark registrations require renewal every 10 years from the registration date to maintain their validity. There is also a declaration of use required between the 5th and 6th years after registration.

Can I search for patents and trademarks for free?

Yes, the USPTO provides free public access to its patent search databases and the Trademark Electronic Search System (TESS) on its website, allowing users to search for existing intellectual property without charge.

Are there different fees for different types of patents?

Yes, the fees vary depending on the type of patent being filed: utility patents, design patents, and plant patents each have their own specific fee schedules for filing, search, examination, and issuance. Only utility patents require maintenance fees.

Does USPTO pricing include attorney fees?

No, USPTO fees cover only the official administrative costs charged by the government agency. Any fees for legal counsel, patent agents, or trademark attorneys are separate and are determined by the individual professional or firm you engage.

USPTO Pricing: Patent & Trademark Filing Fees (2026)

Pricing overview

The United States Patent and Trademark Office (USPTO) employs a comprehensive fee schedule for its services, primarily focused on the examination, issuance, and maintenance of patents and trademarks. Unlike many commercial API providers, the USPTO's fee structure is not based on API calls or data consumption, but rather on the administrative processes involved in securing and maintaining intellectual property rights. These fees are statutory and are subject to periodic review and adjustment by the USPTO, often to recover costs and encourage efficiency in the intellectual property system. Users accessing public data through the USPTO's website or APIs generally do so without direct charge, aligning with the USPTO's mission to disseminate intellectual property information (USPTO patent electronic business center).

Key factors influencing the total cost include the type of intellectual property (utility patent, design patent, plant patent, or trademark), the size of the applicant entity (micro entity, small entity, or large entity), and the specific stages of the application process (filing, examination, issuance, and post-issuance maintenance). Reductions in fees are available for micro and small entities to promote innovation across various economic scales. For example, small entities typically pay 50% of the fees paid by large entities, while micro entities pay 25% (USPTO official fee schedule). This tiered pricing model reflects a policy decision to make intellectual property protection more accessible to independent inventors and smaller businesses.

Plans and tiers

The USPTO does not offer traditional "plans" or "tiers" in the commercial sense of subscription models. Instead, its fee structure is categorized by the type of intellectual property and the applicant's entity status. The primary "tiers" relate to the size of the entity filing the application:

Large Entity: Standard fees apply.
Small Entity: Generally pays 50% of large entity fees. Defined by specific criteria, such as having fewer than 500 employees (USPTO small entity status requirements).
Micro Entity: Generally pays 25% of large entity fees. Requires meeting specific gross income and prior application limits, in addition to small entity criteria (USPTO micro entity status details).

Patent Fee Structure

Patent fees are divided into application filing, examination, issuance, and maintenance fees. The specific fees depend on the type of patent (utility, design, or plant) and the entity size. Utility patents, being the most common, involve several stages of fees:

Filing Fees: Cover the initial submission of the application.
Search Fees: For the USPTO to conduct a prior art search.
Examination Fees: For the examiner to review the application.
Issue Fees: Paid upon allowance of the patent.
Maintenance Fees: Required at 3.5, 7.5, and 11.5 years after issuance to keep the patent in force. Failure to pay these fees results in patent expiration.

For example, a large entity filing a utility patent application might pay an initial filing fee, search fee, and examination fee totaling several thousand dollars, with additional issue and maintenance fees over the patent's life (USPTO patent fee schedule).

Trademark Fee Structure

Trademark fees are generally simpler, primarily focusing on application filing and renewal. Fees are typically assessed per class of goods or services identified in the application. The most common filing options are:

TEAS Plus: Lower fee for applications meeting specific requirements, such as using pre-approved identification of goods/services.
TEAS Standard: Higher fee for applications not meeting TEAS Plus requirements.

Renewal fees are due every 10 years to maintain trademark registration (USPTO trademark fee information).

Free tier and limits

The USPTO provides a robust "free tier" primarily through public access to intellectual property data and examination resources. This includes:

Public Patent Search Database: Access to full-text and image databases of issued US patents and published applications (USPTO patent search tools).
Trademark Search Database (TESS): The Trademark Electronic Search System (TESS) allows users to search registered trademarks and pending applications (TESS trademark search).
Public PAIR (Patent Application Information Retrieval): Provides status information for patent applications.
Trademark Status & Document Retrieval (TSDR): Offers status and document information for trademark applications and registrations.
Developer APIs: The USPTO offers several APIs for accessing patent and trademark data, primarily for bulk data consumption and integration. Access to these APIs is free but requires registration on the USPTO developer portal. These APIs are rate-limited to ensure fair usage and system stability, though specific limits may vary and are detailed in the API documentation. For instance, the Patent Grant Full Text API allows programmatic access to patent data, enabling developers to build custom search tools or integrate patent information into their applications (USPTO API catalog).
Educational Resources: Extensive educational materials, guides, and webinars are available without charge to help applicants understand the intellectual property process.

The primary "limits" on this free access are the statutory fees associated with filing and maintaining actual intellectual property rights. While searching and learning are free, securing and defending a patent or trademark involves the payment of official USPTO fees.

Real-world cost examples

Understanding the total cost of intellectual property protection involves considering both USPTO fees and potential legal or professional fees. Here are illustrative examples based on USPTO fees (excluding attorney fees, which can vary widely):

Example 1: Utility Patent for a Small Entity

A small business (small entity status) invents a novel device and decides to file a utility patent application. The process typically involves:

Initial Filing Fees (e.g., non-provisional utility application): Approximately $800 - $1,000 (includes basic filing, search, and examination fees for a small entity).
Issue Fee: Approximately $500 - $600 (paid upon patent allowance for a small entity).
Maintenance Fees (over 20 years):
- 3.5 years: ~$1,000
- 7.5 years: ~$2,000
- 11.5 years: ~$3,500

Total USPTO fees over 20 years: Approximately $7,800 - $8,600. This does not include any potential fees for filing continuations, appeals, or legal counsel.

Example 2: Trademark Registration for a Large Entity (TEAS Plus)

A large corporation wants to register a new brand name for a single class of goods using the TEAS Plus application system.

Initial Filing Fee (TEAS Plus, per class): Approximately $250.
Renewal Fee (every 10 years): Approximately $400 - $500 per class.

Total USPTO fees for 10 years: $250. If maintained for 20 years, an additional $400-$500 would be due. This excludes any fees for office actions or legal assistance.

Example 3: Design Patent for a Micro Entity

An individual inventor (micro entity status) files a design patent for a unique product aesthetic.

Initial Filing Fees (e.g., design application): Approximately $100 - $150 (includes basic filing, search, and examination fees for a micro entity).
Issue Fee: Approximately $200 - $250 (paid upon patent allowance for a micro entity).

Total USPTO fees over 15 years (design patents do not have maintenance fees): Approximately $300 - $400. This again excludes professional fees.

How the pricing compares

Comparing USPTO pricing directly with alternatives like the European Patent Office (EPO) or the World Intellectual Property Organization (WIPO) involves understanding their distinct jurisdictions and fee structures. While the USPTO focuses solely on intellectual property within the United States, EPO grants European patents valid in multiple member states, and WIPO administers international treaties like the Patent Cooperation Treaty (PCT) and the Madrid System for trademarks, offering centralized filing mechanisms.

Here's a generalized comparison:

Entity/System	Primary Function	Pricing Model Overview	Key Differences
USPTO	US Patents & Trademarks	Fee-for-service; tiered by entity size (micro, small, large); statutory fees for filing, examination, issuance, and maintenance.	Jurisdiction limited to the U.S. Fee reductions for smaller entities.
European Patent Office (EPO)	European Patents (valid in member states)	Fee-for-service; includes filing, search, examination, and renewal fees. No direct entity size discounts, but national phase entry costs vary.	Single application can cover up to 40+ countries. Renewal fees are paid annually to the EPO until grant, then to national patent offices.
World Intellectual Property Organization (WIPO) - PCT System	International Patent Applications	Fee-for-service; international filing fee, search fee, and preliminary examination fee. National phase fees paid to individual countries.	Centralized filing for multiple countries via a single application, delaying national phase costs. Total cost depends on how many countries are pursued.
World Intellectual Property Organization (WIPO) - Madrid System	International Trademark Applications	Fee-for-service; basic fee, supplementary fees per designated country/region, and complementary fees for additional classes.	Single application for multiple countries, simplifying management. Fees are paid directly to WIPO.

The USPTO's fees are generally competitive for protection within the United States, especially for micro and small entities due to significant fee reductions. For global protection, WIPO's PCT and Madrid systems offer cost-effective routes for initial filing and deferring national phase costs, but ultimately require payment of national fees in each desired jurisdiction. The EPO provides a single patent that can be validated in many European countries, potentially reducing the administrative burden compared to filing in each country individually, though its overall costs can be substantial, particularly when accounting for translation and validation fees post-grant (EPO fee schedule).

It is important to note that direct comparisons of "total cost" are complex, as they depend heavily on the scope of protection desired, the number of countries, and whether professional legal assistance is utilized. The USPTO's API access, being free, aligns with the general trend of government agencies providing public data access without charge, contrasting with some commercial API providers that charge per call or data volume (Google Maps Platform pricing).
