Provisional patent example download more examples from here: http://patentfile.org/provisionalpat...

A good provisional patent example is actually very hard to find. This is because provisional patent applications are never published and therefore most remain secret. The trick that I use to find provisional patent examples is that you can search the USPTO website for people who converted their provisional patent application to nonprovisional patent applications and at that point those documents become public and are listed on the USPTO website.
If you are searching for a provisional patent example in order to create your own provisional patent application this is NOT a good idea. The reason why this is not a good idea is that provisional patent applications are never examined by the USPTO so some of them may be very good and some of them may be poorly written. A better idea would be to search of issued patents that are closely related to your idea and instead use those as your guide or template to write your own provisional patent application. By doing this you at least know that these patent applications have passed the screening and examination process at the USPTO.
