To file for a provisional patent in the United States, prepare a provisional patent application and submit it through USPTO Patent Center. The application can establish an earlier filing date for adequately supported subject matter; it does not itself grant a patent. This guide covers the documents, submission checks and follow-up planning for an online filing.

A provisional application is a U.S. filing option for a utility or plant invention; it is not a patent grant and is not examined on its merits. Filing online requires using the USPTO Patent Center and paying the applicable filing fee. Fees vary by applicant status and can change, so check the current USPTO fee schedule before filing.
This article will show you how to file provisional patents online.
To file electronically, prepare the application papers and submit them through USPTO Patent Center. A provisional application generally includes a written description that explains the invention, any drawings needed to understand it, a provisional cover sheet (or equivalent bibliographic information), and the applicable filing fee. Follow Patent Center prompts to validate and submit the documents and payment; check the filed record after submission.
What Is Provisional Patent Applications?
A provisional application can establish a U.S. filing date for the subject matter adequately described in it. It is not examined and does not itself become a patent. To claim its benefit, a corresponding nonprovisional application generally must be filed within 12 months and properly reference the provisional. Later claims receive the earlier date only to the extent the provisional supports them.
Why Should You File Provisional Patent Applications Before Filing a Full Patent Application?
A provisional application can provide an earlier U.S. filing date for supported subject matter while you prepare a nonprovisional application. The usual period to file that corresponding nonprovisional application and claim the provisional benefit is 12 months, not six months. A U.S. provisional does not create international patent rights or remove the need to meet each country’s filing rules. Public disclosure, sale or use can affect rights differently by jurisdiction, so get qualified patent advice before disclosure.
How Do I File a Provisional Patent ?
Submit the provisional application through USPTO Patent Center. Before filing, confirm the required bibliographic information and prepare a complete written description, drawings needed to understand the invention, and the correct cover sheet or equivalent information. Review current USPTO instructions and fee requirements rather than relying on an old online form or checklist.
A written description that explains the invention in enough detail to support subject matter for which you may later seek the provisional filing date;
Drawings needed to understand the invention;
The names of all actual inventors;
A provisional cover sheet or equivalent information identifying the application as provisional; and
The applicable filing fee. Check current USPTO Patent Center instructions for submission and payment.

When Can I File My Provisional Patents Application?
The corresponding nonprovisional application is generally due within 12 months after the provisional filing date if you want to claim its benefit. The provisional is not examined and expires after its 12-month pendency. A provisional application cannot be filed for a design invention. Requirements and exceptions are fact-specific; confirm current USPTO guidance and consult a registered patent practitioner.
