It is not easy to find a provisional patent example because they are not published or easily searchable online like regular utility non-provisional patents. A non-provisional patent application will get published about 18 months after you file it.  A provisional patent application will remain secret.  This is either an advantage or a disadvantage of a provisional patent application. If you want to learn more about a provisional vs. a non-provisional please read this post.

A real example of an old provisional patent application I filed a few years ago:


If you look at the examples above, a provisional patent application should look exactly like a regular non-provisional application so its a lot easier to search for those and use those as your template or guide.  If you want to learn how to search patents, I wrote an short guide here: How to Search Provisional Patents.

The parts of a provisional patent application should be:

  1. The specification (the written description of your invention)
  2. The figures (show what your invention looks like)
  3. The transmittal letter or cover sheet (this shows who the inventors are and who is filing the application)

A provisional patent application does not need claims or formal drawings.  This is one reason why it's a lot cheaper to file a provisional patent application because you can save on the costs of having fancy drawings made.  There is some debate amount patent experts on the need to include claims with a provisional patent application.  Although they are not technically required, there are some reasons why it would be beneficial to have at least one claim.  In my video guide that I provide to my clients I share with them the reasons why I think writing one good claim is very important.
