Provisional patent application

Methods For Writing A Provisional Patent Application

To correctly write a provisional patent application, it should have two things: 1) a detailed explanation of how the invention functions and 2) a set of technical drawings that helps in that explanation. The fundamental idea is that a provisional patent application must completely describe how the invention functions, including the parts that build the invention and their arrangement. It isn’t protected if any element of the invention is not explicitly specified.

Write as much as possible because you can only protect what you describe.

The idea that a provisional patent application does not need to be written in-depth is popular. After all, it’s only a temporary or provisional patent application. Wrong! Unexplained information is not protected. Consider this: Would you believe I could prohibit anyone from ever creating the time machine or from claiming to have invented one before me if I submitted a patent application that includes only the term “The machine that can go through time”? Not.

I cannot even obtain provisional patent protection until I truly understand how to build a time machine and connect all of the necessary parts. Therefore, the first thing to remember is that you must clearly explain how the invention functions.

Are you capable of explaining the invention’s workings on a technical level?

Not all inventors can correctly describe the invention’s parts and how they are put together. Do you, for instance, understand which other parts your device is connected to and how it influences how your entire innovation functions, assuming it contains an operator? Would you please elaborate? It is necessary to provide enough information in a provisional patent application so that the invention can be reproduced by someone who understands it.

A patent attorney or agency should prepare the patent application if you lack engineering experience. Even patent attorneys and agents frequently ask for the assistance of engineers who are experts in the field of your invention to help with the preparation of the patent. This is because the efficiency of the story’s technical description significantly impacts the quality of the patent application. It is best to have someone else prepare the patent application as an expert, even if you have engineering experience.

Remember that the patent application must reveal the invention in enough detail to enable someone else to make it. You are already acquainted with your idea. Therefore, you might exclude information from your patent application that you believe is unimportant, but the person reading the application might not be. To ensure that others, not just you, can understand how your innovation works, it is best to have someone else write the application.

Instead of describing what the invention offers, explain how it works.

The invention’s performance, not its features, must be the primary focus of a patent application. These two are highly distinct. When I claim to have designed a device capable of time travel, I am referring to the device’s performance. However, a patent application needs to reveal how it functions.

Specifically, how the invention functions, how its parts are put together, and what elements make up the invention. Many innovators go excessive when describing their invention’s capabilities, greatness, and ability to influence the course of human history.

The Patent Office, however, is more interested in how an invention functions than what it can perform. The patent will not entirely protect your design if you don’t get enough information about its performance.

Design and Build technical patent drawings

As we’ve already discussed, the protection of a provisional patent process depends on how effectively the patent application enables someone to understand how the invention works. Visual effects are essential in helping a reader understand how a design works.

Drawings are a crucial component of the provisional patent application because of this. Technical drawings are necessary for individuals with technical expertise to understand how an innovation functions. Technical computer-aided design (CAD) drawings used for patents are commonly used to describe all the parts of an invention and their arrangement.

To further explain how the parts are put together, patent drawings sometimes represent the invention cut open or destroyed. It is advised to hire a patent expert to create technical patent drawings if you cannot do it yourself to guarantee that your invention is adequately covered in the patent application.


Only the information you clearly describe how a provisional patent application protects your invention functions. It secures less than the less information you include. Fewer technical writing or technical drawings means less protection. Recall the last “time machine” example.

I won’t be protected if I submit a provisional patent application that states that I created a time machine in a few short words. Ask a patent expert to completely comprehend your innovation and develop a set of patent text and patent drawings that fully describe how it works.
