To acquire U.S. patent rights, identify the type of protection you need, search for prior art, prepare and file an application with the U.S. Patent and Trademark Office (USPTO), respond to examination, pay the issue fee if the application is allowed, and maintain the patent after it issues. Filing an application is a request for examination—not a patent grant or a guarantee of approval. A provisional application is optional and does not itself become a patent.
1. Decide whether a patent fits your invention
U.S. patent protection is limited to the United States. The USPTO identifies three broad patent types, distinguished by what they protect:
| Patent type | General subject matter |
|---|---|
| Utility | New and useful processes, machines, manufactures, or compositions of matter. |
| Design | New, original, ornamental designs for articles of manufacture. |
| Plant | Distinct and new plant varieties that are asexually reproduced. |
These descriptions are general; eligibility depends on the invention and the applicable requirements. If patent protection does not match what you want to protect, other forms of intellectual property, such as trademark or copyright, may be relevant. See the USPTO overview of patents.
2. Search for prior art before filing
Look for similar inventions in patent records and other public material, including published applications, patents, printed publications, public uses, sales, and other disclosures. The USPTO advises searching before applying; an invention generally cannot be patented if it was already publicly available.

A search is an initial check, not a guarantee that an application will be granted or a legal determination that you can safely make, use, or sell the invention. The examiner conducts a separate search and review during examination.
3. Choose a filing route and prepare the application
You can file a nonprovisional application directly or first file a provisional application. A provisional is a temporary filing option, not a cheaper or simpler version of a granted patent. The key differences are:
| Question | Provisional application | Nonprovisional utility application |
|---|---|---|
| Is it examined? | No. | Yes; it is reviewed for compliance and patentability. |
| Can it itself issue as a patent? | No. | It may issue if the requirements are met. |
| What is due at filing? | It must adequately disclose the invention for which you later seek the benefit of the filing date. | Generally, a specification with a description and claims, drawings when necessary, an oath or declaration, and filing, search, and examination fees. |
| What follow-up is required? | File a corresponding nonprovisional application within 12 months to claim its benefit. | Follow the examination process and meet applicable deadlines. |
| What must a later claim have? | The subject matter must be supported by the provisional disclosure to receive its benefit. | Claims are examined as part of the application. |
The USPTO explains the application routes and filing process and provides a utility patent application filing guide. Applicants may use a registered patent attorney or agent to prepare and file an application.
If you file provisionally, calendar the deadline
A provisional application is automatically abandoned 12 months after its filing date. To claim its benefit, file a corresponding nonprovisional application during that period. The provisional supports later claims only to the extent it actually describes the relevant subject matter; material first added later does not gain support from the earlier filing merely because a provisional was filed.

4. File with the USPTO and respond to examination
The USPTO accepts electronic patent filings through Patent Center. After a nonprovisional application is accepted, an examiner reviews it for compliance and patentability. The examiner searches patents, published applications, foreign patent documents, and available literature.
The examiner may issue objections or rejections. You can respond in writing, amend the application where appropriate, or argue why the examiner should allow it. If issues remain unresolved, additional examination or an appeal may follow. Filing alone does not confer patent rights.
5. Understand publication and possible provisional rights
Utility and plant applications are generally published 18 months after the earliest effective filing or claimed priority date, subject to exceptions, including eligible nonpublication requests. Publication is not a patent grant. The USPTO describes possible provisional rights after publication, but they are conditional: they require actual notice and a patent issuing with a substantially identical claim. See the USPTO’s patent process guidance.
6. Pay the issue fee if the application is allowed
If the application is allowed, the USPTO sends a Notice of Allowance and Fee(s) Due. The fees listed in the notice must be paid within three months of its mailing date; missing that deadline results in abandonment. The patent issues after payment and resolution of any remaining issues. Check the current USPTO fee schedule because amounts can change. Fees do not guarantee a grant.

7. Maintain and manage the issued patent
Utility and plant patents generally have a term of 20 years from the U.S. filing date, subject to applicable qualifications and adjustments. Utility patent maintenance fees are due 3.5, 7.5, and 11.5 years after grant. The patent owner is responsible for maintaining and enforcing the rights.
A U.S. patent gives its owner the right to exclude others from making, using, offering for sale, selling, or importing the invention in the United States for a limited time. It does not itself give the owner permission to practice the invention or provide protection in other countries. For current maintenance requirements and management information, consult the USPTO patent maintenance guidance.
How long does getting a patent take, and what does it cost?
Pendency—the time from filing until grant or abandonment—and fees depend on the application type and processing circumstances. The USPTO does not promise a particular timeline or outcome, and paying application fees does not ensure approval. Because fee amounts and filing procedures can change, check the current USPTO instructions and schedule when preparing to file.
