Provisional patent application filing is a smart move if you’re an inventor or run a business. Securing your invention early helps you avoid problems later. It’s a simple, cost-effective way to protect your idea while giving you extra time to refine it before filing a full patent.

What Is a Provisional Patent Application?
A PPA is a short-term filing you send to the USPTO to get your invention protected. It doesn’t have formal patent claims, complicated law documents or an instant detailed examination, unlike a full patent application. By doing this, it simply takes less time, is simpler to do and lowers your financial costs.
A provisional patent application allows you to declare that your invention is “patent pending.” While you are getting your complete application ready, your idea is legally protected. In the first 12 months, you are able to claim the date of your provisional filing by submitting a full patent (called a nonprovisional patent application).
How to Draft a Provisional Patent Application Explained Clearly
Filing a provisional patent application does not have to be complicated; it’s a clear way to secure your invention early. Think of it as a temporary certificate that allows you a year to finish your full patent.
Here is the easy way to write your letter:
- Pick for your title a short sentence that tells readers what your invention does.
- Tell readers about your invention, including its process, results and what makes it special. Provide all the details you can give.
- Add drawings or sketches to your notes — they make your invention easier to understand.
- Optional for provisional, but you can include claims to explain what of your invention you want protection for.
- Share any interesting work you have done — describe why your invention is unique compared to others.

- Keep in mind, a provisional patent application gives you only temporary patent benefits and allows you to polish your invention before filing the formal one.
- You can defend your ideas early and on a budget and you don’t need a lawyer to start.
