A provisional patent application is designed to establish the date on which you filed the application and gets expired exactly one year after that. Only because of this reason people use to file this patent. With this they can save their invention even then, when they are not prepared for the examination process carried on by USPTO. According to the experts’ opinion, your reason for filing the provisional application should be something logical and you should not do this simply because you want to save some money at this point of time. Moreover, whether you are filing application for provisional patent or non-provisional one, you need to be very careful.
As an US provisional patent, you should know that a provisional application for patent is not verified by the Patent and Trademark Office and does not get matured automatically as patent. It is just because the application you file can be veiled only up to 12 months. The only advantage is that you not need to hire the professional lawyer as the provisional application is simple to make. However, you need to complete all the documents and requirement for successful patent.

All you just need to make sure that the application is same with exact details that you are going to use in regular application. This is very important as after it you are going to claim for the patent for the next twenty years.
