File a Provisional Patent Online

Filing a provisional patent application online is now the standard way inventors secure an early filing date with the USPTO. While paper filing is technically still possible, nearly all patent applications today are submitted electronically because it is faster, easier, and—in some cases—less expensive. This page explains what it actually means to file a provisional patent online, the available filing options, common mistakes to avoid, and how to submit your application correctly.

What "Filing Online" Means

When people refer to "filing a provisional patent online," they generally mean submitting a provisional patent application electronically through the USPTO's Patent Center system. This includes uploading your already-drafted provisional application, completing and uploading the required forms that need to be submitted with the application, and paying the appropriate fees—all in one online session.

Although filing by mail or fax is still technically allowed in limited circumstances, electronic filing is overwhelmingly preferred and is the method used by inventors, startups, and patent professionals in nearly all cases.

High-Level Steps to File a Provisional Patent Online

At a high level, the online filing process involves:

1. Preparing the provisional patent application (the written description and any drawings)
2. Completing the required filing forms
3. Submitting the application and the forms electronically through the USPTO's Patent Center
4. Paying the required government filing fees
5. Downloading and saving the electronic filing acknowledgment and confirmation details

Three Ways to File a Provisional Patent Online

There are several options for you to file your provisional patent application online. The best approach depends on your budget, timeline, and comfort level with assuming risk.

Option A: File It Yourself Online (DIY)

Some inventors familiar with the patent system choose to file a provisional patent application on their own by submitting everything directly through the USPTO's online system using their own registered account with the USPTO.

Filing electronically does not eliminate risk. Some of the most common mistakes made during online provisional filings include failing to submit the proper paperwork, completing the Application Data Sheet (ADS) incorrectly, claiming micro-entity fees without filing the certification, failing to download the USPTO electronic filing acknowledgment, and missing or underpaying required fees.

File Your Provisional Patent Online With Confidence

Filing a provisional patent application online can be an effective way to secure an early filing date—but only if it is done correctly. The quality of the disclosure, the accuracy of the paperwork, and proper fee payment all matter.
