How To Write A Patent Application

If you have an invention that you want to protect from being copied or used by others without your permission, you may need to apply for a patent.

A patent is a legal document that grants you the exclusive right to make, use, or sell your invention for a limited period of time. However, getting a patent is not easy.

You need to follow a specific process and meet certain requirements to convince the patent office that your invention is new, useful, and non-obvious.

In this article, I will explain how to write a patent application that can increase your chances of getting a patent for your invention.

What is a Patent Application?

A patent application is a formal request to the patent office to grant you a patent for your invention.

A patent application must include:

  • A description of your invention that allows others to see how it works and how it could be made
  • Legal statements that set out the technical features of your invention that are to be protected (known as ‘claims’)
  • A summary of all the important technical aspects of your invention (known as the ‘abstract’)
  • Any drawings, diagrams, or photographs that illustrate your invention

The application can be either provisional or non-provisional. A provisional patent application (PPA) is a temporary document that establishes an early filing date and gives you a pending status.

A PPA does not require claims or formal drawings, and it is not examined by the patent office.

However, you must file a non-provisional patent application (NPPA) within one year of filing a PPA, or else you will lose your priority date and your patent rights.

A NPPA is a complete and final document that requires claims, formal drawings, and fees, and it is examined by the patent office to determine if your invention is patentable.

How to Write a Patent Application: Step by Step

Writing a patent application can be a complex and time-consuming task. However, you can follow these steps to make it easier and more effective:

  1. Determine the type of intellectual property (IP) protection you need. Not all inventions need a patent. You may also consider a trademark, a copyright, or a trade secret, depending on the nature and purpose of your invention.
  2. Determine if your invention is patentable. To be patentable, your invention must be novel, useful, and non-obvious. This means that your invention must not have been publicly disclosed, used, or sold by anyone else before you filed your patent application, that your invention must have a practical application or benefit, and that your invention must not be an obvious improvement or variation of an existing invention.
  3. Search to see if your invention has already been publicly disclosed by another party. You cannot get a patent if your invention has already been publicly disclosed. Therefore, you should conduct a thorough search of all previous public disclosures, including patents, publications, websites, and databases, to see if your invention or something similar has already been invented or disclosed by someone else.
  4. Prepare your patent application. You should write your patent application in a clear, concise, and accurate manner, using technical terms and language that are appropriate for your field of invention. You should also follow the format and guidelines of the patent office that you are applying to.
  5. File your patent application. You should file your patent application with the patent office that has jurisdiction over your invention. You may also file your patent application in multiple countries or regions, if you want to protect your invention internationally. You should pay the required fees and submit the required documents and forms along with your patent application. You should also keep a copy of your patent application and any correspondence with the patent office for your records.
  6. Wait for the examination and prosecution of your patent application. After you file your patent application, the patent office will assign an examiner to review your patent application and conduct a search of prior art. The examiner will then issue a report or an office action, either granting or rejecting your patent application, or requesting further information or amendments.
  7. Receive your patent. If your patent application is approved, the patent office will issue you a patent certificate and publish your patent application. You will then have the exclusive right to make, use, or sell your invention for the duration of your patent term, which is usually 20 years from the filing date of your patent application. You will also have to pay renewal fees to keep your patent valid.
