Patents protect an invention so that only the inventor may make the invention for a limited time. It incentivizes inventors to invent by rewarding the inventor with a temporary monopoly. However, the process in filing a patent application to try and obtain a patent is complex and daunting for many individuals and businesses. This guide aims to demystify the process of filing a patent application, providing step-by-step instructions and key considerations to increase the chances of successfully obtaining a patent.
Understanding Patents
Before embarking on the patent filing journey, it is essential to have a clear understanding of what a patent is and the types of inventions that can be patented. A patent is a legal right granted by the government that gives the inventor exclusive rights to their invention for a limited period of time. Patents grant inventors with the right to prevent others from making, using, selling, or importing their invention without permission.
There are three main types of patents: utility patents, design patents, and plant patents. Utility patents protect new and useful processes, machines, compositions of matter, or improvements to existing inventions. Design patents protect the unique ornamental design of a useful item. Plant patents are granted for distinct and new varieties of plants.
Conducting a Patent Search
Before proceeding with a patent filing, it is crucial to conduct a thorough patent search to determine if your invention is novel and non-obvious. A patent search involves examining existing patents, published patent applications, scientific literature, and other publicly available resources to assess the prior art landscape related to your invention. Anything similar found in the public can be used as a reason by the patent office to say you do not deserve a patent.
The United States Patent and Trademark Office (USPTO) provides an online patent search engine which can be used for conducting a patent search. Additionally, professional patent search firms with patent attorneys and patent agents can perform a comprehensive patnet search.
Drafting a Patent Application
Once you have determined the novelty and non-obviousness of your invention, the next step is to draft a patent application. A well-drafted patent application is crucial for ensuring that your invention is adequately protected and that your rights are clearly defined.
Patent applications typically consist of several sections, including a title, abstract, background of the invention, summary, detailed description, drawings, and claims. It is essential to describe your invention in enough detail to allow someone to “make and use” the invention. A patent application that does not have enough detail to allow someone to “make and use” the invention may not obtain a patent.
When drafting a patent application, seeking the expertise of a registered patent attorney or patent agent is highly recommended. These professionals have the necessary legal and technical knowledge to navigate the complexities of the patent system and ensure that your application meets the required standards. A poorly drafted patent application will not protect the invention and usually cannot be fixed because once a patent application is filed, major changes cannot be made. Usually, a poorly drafted patent application requires an inventor to start over by filing a new patent application that is properly drafted.
Filing the Patent Application
Once the patent application has been drafted, the next step is to file it with the patent office. In the United States, the US Patent and Trademark Office (USPTO) is responsible for examining and granting patents.
When filing a patent application, it is crucial to pay the necessary filing fees and ensure that all required documents, including the specification, drawings, and claims, are submitted properly. Missing or incomplete information can result in delays or rejection of the patent application.
Patent Examination and Prosecution
After filing the patent application, it undergoes a thorough examination process conducted by a patent examiner at the patent office. The examiner assesses the patentability of the invention based on the criteria of novelty, non-obviousness, and usefulness. The examination process may involve multiple rounds of correspondence between the inventor and the examiner, known as patent prosecution.
During the prosecution phase, the examiner may issue office actions, which are written communications that raise objections, rejections, or require amendments to the patent application. It is essential to carefully review and timely respond to these office actions to address the patent examiner’s concerns and make amendments as necessary to increase the chances of obtaining a patent.
Patent Grant or Rejection
Based on what happens during examination and prosecution, the patent examiner will make a decision to either grant or reject the patent application. If the examiner determines that the invention meets the patentability criteria and all requirements have been met, the examiner will send a Notice of Allowance, and the patent will be granted upon payment of the patent issue fee.
In case of a rejection, the inventor has the option to try and convince the examiner that the invention is different enough from other inventions to deserves a patent. It is crucial to carefully consider the examiner’s objections and seek professional advice to overcome any of the examiner rejections. Patent attorneys and patent agents see rejections on a daily basis and know the arguments and amendments to make which may result in patent application approval.
International Patent Filing
In today’s global economy, inventors often seek patent protection beyond their home country. Each country has their own patent office, and a patent application must be filed in each country an inventor seeks to obtain a patent in. It is important to file patent applications internationally within 12 months of the first patent application you file in the United States. If you wait more than 12 months after you file your first patent application in the United States, you may give up the right to obtain a patent in many countries. After filing a patent application in the United States, if you need more than 12 months to decide which countries to file patent applications in, you may file a Patent Cooperation Treaty (PCT) application which can buy you 18 more months of time to decide.
Filing a patent is a complex but potentially rewarding journey which may allow inventors to protect their intellectual property by preventing others from making their invention. Not all patent applications will be approved as the US Patent Office grants patents only to those inventions it considers to be novel and nonobvious. Hiring an experienced patent firm that has helped many inventors obtain patents will increase the chances of convincing the US Patent Office that your invention meets the patentability criteria to deserve a patent.
