What Is a Provisional Patent Application (PPA)?

A provisional patent application (PPA) is a type of patent application that can be used to protect an invention before filing a full patent application. The provisional patent application (PPA) gives the inventor the right to claim “patent pending” status for their invention.

The provisional patent application must include an invention description, which includes drawings and/or photographs of the invention and provides a detailed description of the invention. The provisional patent application is good for 12 months and does not require a formal patent claim.

What Are the Benefits of a Provisional Patent Application?

The main benefit of a provisional patent application is that it allows an inventor to quickly and inexpensively protect their invention and get the “patent pending” status without a full patent application. The provisional patent eliminates the need to meet the strict formalities that are necessary for a full patent application and will provide limited patent protection for the full 12 months of filing.

In addition, a provisional patent application can help reduce the cost of getting a full patent. The filing fee for a provisional patent application is much lower than the filing fee for a full patent application and the inventor can decide within the 12 month period whether to proceed to full patent protection or not.

How Do I File a Provisional Patent Application?

Filing a provisional patent application is relatively easy. You can either file the provisional patent application yourself or with the help of a lawyer. The provisions for filing and the criteria for application are specified in the Patent Act. Before filing the provisional patent application, it is recommended that you research the current state of your invention to ensure you do not infringe on any existing patents.

Once the provisional patent application is filed, it is important to be aware that you will have only limited legal protection. It is also important to note that you will need to complete the full application within twelve months in order to gain the full benefits and legal protection of a patent.

Related Legal Concepts

Understanding provisional patent applications often goes hand in hand with utility patents and design patents, which represent the full patent applications that may follow. The United States Patent and Trademark Office (USPTO) processes these applications and grants patent pending status during the provisional period. Those pursuing patent protection should also be familiar with patent claims, patent infringement risks, and the importance of conducting a thorough patent search before filing any application.

The Bottom Line

A provisional patent application serves as an affordable first step in the patent process, providing temporary protection while inventors develop their ideas and assess commercial viability. This 12-month window allows inventors to secure an early filing date and use “patent pending” status without the complexity and expense of a full patent application.
