Enriching Life Through Innovative Ideas SM



In 2011, President Obama signed the Americans Invent Act (AIA), which led to enormous changes in patent procedure and law. The changes were slowly implemented, but one of the most drastic changes was converting America’s historic first-to-invent system into a first inventor to file system. 

Under the new first-to-file system, priority for an invention is given to the first person that discloses the invention and files for an application first. As a result of these changes, filing a provisional patent application is more important than ever. 

The Importance of a Provisional Patent Application

There is no such thing as a “provisional patent”, but what an inventor files for is referred to as a provisional patent application. A provisional patent application should be filed as soon as the invention is tangible and can be described. Immediately upon filing the provisional patent application, the inventor can declare that they have “patent pending” on the invention.

When improvements are made to the invention, the inventor can choose to file another provisional patent or file a nonprovisional patent. It is important to note that new subject matter cannot be added to a nonprovisional patent. However, an inventor can wrap together multiple provisional patents when filing for the nonprovisional patent.

A provisional patent application is beneficial for inventors who are perfecting an invention because they are able to file for a provisional patent application for all aspects of their invention as they are developing them.

How to File a Provisional Patent Application

A provisional patent application can be filed without an attorney, but there are critical elements that must not be overlooked. Along with the filing fee, the application must include a cover letter that identifies the following:

  • The application as a provisional application for patent
  • The name of all inventors
  • The residence of the inventors
  • Title of the invention
  • Name and registration of the attorney or agent (if applicable)
  • Correspondence address

• If any U.S. agency has property interest in the application.

The application requires a written description of the invention and patent drawings to support the invention. In order for the provisional application to be useful in establishing priority when filing for the no provisional patent, it must accurately describe the invention. The saying “a picture is worth a thousand words” is especially relevant when filing for a patent. Drawings are crucial in the application because they can cover areas of the invention not included in the written disclosure.

Filing a provisional patent application is a good way to begin the patent process because it is inexpensive to prepare and file. Since there are no formal requirements for the provisional application, the main focus of the application is to disclose the invention in full detail.

What Next?

After filing a provisional patent application, the inventor must file for a nonprovisional patent application within 12 months. The filing date of the nonprovisional patent will be the initial filing date of the provisional patent, which is advantageous for the inventor under the first-to-file system. A nonprovisional patent must be filed within the 12-month period, a deadline that cannot be extended for any reason.

When preparing to file the provisional patent application, it is important to disclose as much information as possible because an inventor will only receive the benefits of an earlier filing date with respect to what was previously disclosed.

Filing a patent can be a long and tedious process. However there are benefits to filing a provisional patent especially for inventors who are unsure if there is a demand for the product or inventors with a tight budget. Obtaining a provisional patent allows an inventor to continue to develop the invention and test the market before investing in a nonprovisional patent which are requires a great amount of time and resources.

A provisional patent application must be carefully prepared; otherwise, the provisional patent will not provide any benefits for the inventor and can create complications later in the patent application process.

I came to Tommy for help reviewing a licensing agreement I had secured with a well-known manufacturer. Tommy made sure I understood all the details in the contract and he negotiated with the company to improve my side of the deal. I mentioned to Tommy at my first consultation that we were looking to expand throughout the US and were investing a lot of money to make a big entrance into the market. I did not think I would have my store open so soon but Tommy also has connections with the local area and realtors to help me secure the location for my first store in the Los Angeles area. Tommy works a lot with the local businesses and he understands how to transition from the Asian market to US market. Within 8 months my store was open for business and fully operating. I must recommend Tommy to any business owners looking for help with contracts and improving their side of the deal. Tommy has the knowledge and experience to make sure there is a smooth process to open for business here, and make sure that your company is set up for success.


I think Tommy and his team by far considered the best people to work with in my 16 business years. Beside quick responses to all my inquiries, they also done things right and providing very professional solutions. I’m highly recommending Tommy and his firm to all business owners.

I have been working on my Utility Patent for almost 4 years. I have hired and fired two very reputable IP firms because with all their expertise and reputation for being some of the top firms in IP Law, I felt a lack of connection and care in my product, time and financial investment.

After 4 years, I finally found a legal team that I felt spent the time to really understand the components of my utility patent. Tommy also very mindful of cost and how and where my money would be better spent. I really feel I am in great hands with Tommy and his team. They have been patient with my revisions.
