Patent basics

If you've had a great idea and you're worried someone else might file first, a provisional patent application (PPA) is often the smartest first move.

Think of a provisional as planting your flag: you lock in an early filing date and "patent pending" status, then get up to 12 months to build, test, and raise money before committing to a full (non-provisional) utility patent.

Key takeaways

What is a provisional patent?

A provisional patent application is a temporary, one-year filing with the U.S. Patent and Trademark Office (USPTO) that:

To get an issued patent, you must file a non-provisional (utility) application that claims priority to your provisional within 12 months. For many individual inventors and small businesses, the big appeal is:

The power of "patent pending" status

Once you file a valid provisional, you can usually label your invention "patent pending." That status:

"Patent pending" itself doesn't give you enforceable rights until you follow up with a granted patent — but it's a strong business signal and part of a solid IP strategy.

Provisional vs. non-provisional (utility) patent

Here's a quick comparison:

Feature Provisional (PPA) Non-provisional (Utility)
PurposeSecure early filing date; 12-month placeholderExamined for a full 20-year grant
Cost (micro entity)~$65 filing fee~$400+ fees, plus possible attorney costs
Duration12 months (no extensions)Up to 20 years from filing
ComplexityDetailed description + drawingsFormal claims, strict formats, declarations
Status granted"Patent pending"Granted patent (if approved)
USPTO examinationNot examinedFully examined

A common strategy: file a provisional now, then decide within 12 months whether to invest in a full utility application.

How to use your 12-month window strategically

That one-year period after filing is valuable. Use it to:

Common misconceptions
Myth: A provisional gives you the same rights as a full patent.
Reality: it's just a placeholder filing and priority date. You don't get enforceable rights until a non-provisional is filed and granted.
Myth: You can extend a provisional beyond 12 months.
Reality: you cannot. If you don't file a non-provisional within 12 months, you lose that priority date.
Myth: A short, vague description is enough.
Reality: it must be detailed enough that someone skilled in the field could make and use your invention. Thin descriptions can fail to protect what you think they do.
