Poorly done provisional applications are almost certain to be useless for their intended purpose. Bad provisional applications can be used against the inventor later as a weapon to demonstrate there was no invention, or at least that the invention had not ripened past the idea stage at the critical moment the invention was memorialized at the time of filing the provisional patent application. Therefore, it is critically important to understand what is required in a provisional application. It is likewise important not to fall prey to those who knowingly or unknowingly prey on unsophisticated inventors. There is a popular misconception about drawings in provisional patent applications. Many believe that drawings are not necessary in provisional patent applications, and some non-attorney services and courses suggest that drawings are not required. Apparently, the belief is that the requirements for provisional patent applications are different than for non-provisional patent applications. This is simply not the case. This is very bad advice.
High quality, professional patent drawings are without a doubt the single best way to disclose an invention in any patent application. In a provisional application the goal is generally to disclose the invention quickly in an economically feasible yet business responsible manner. That absolutely must mean you are filing with patent drawings, hopefully at least several patent drawings and hopefully more. If you file high quality, professional drawings every drawing will tell its own story on its own. If you are doing what you are supposed to you will include at least one paragraph (hopefully more) describing what is shown in each figure. There is simply no way around it — drawings are essential!
Yes, provisional patent applications require fewer formalities. This means the focus can be on the disclosure of the invention rather than the form of the disclosure, but the disclosure must be as complete as a non-provisional patent application in order to provide a useful priority date. If drawings are necessary to understand the invention they are absolutely necessary in a provisional patent application.
