Two Minute Drill: How the U.S. Patent Application Process Works

A high-level rundown of the timeline of going from patent application to granted patent.

To obtain U.S. patent protection for a new and useful process, machine, article of manufacture, or composition of matter—or an improvement to the same—a non-provisional application for a utility patent may be submitted to the United States Patent & Trademark Office (USPTO).See 35 U.S.C. §§ 101, 111. This application may claim priority to a provisional patent application’s filing date if filed within a year of filing the provisional application and if disclosure requirements are met.See 35 U.S.C. § 119(e). In most cases, it’s critical to secure the earliest possible filing date for the application, as the U.S. patent system is a first-inventor-to-file system, rather than the former first-to-invent system. Once filed, the claimed invention is patent pending. The application is published approximately eighteen months after its effective filing date.See 35 U.S.C. § 122(b).

Typically, an applicant waits eighteen to thirty months from the effective filing date for examination of the application. The examiner considers whether the claimed invention is accompanied, inter alia, by sufficient enabling disclosure, is directed to eligible subject matter, is novel, and would not have been obvious to a person having ordinary skill in the art. At this point, it’s common for an application to receive at least one rejection in an office action—a recent study has shown over 80% of applications do, including those eventually allowed Chad Gilles, How Often Do Patent Applications Get Rejected?, BigPatentData (May 16, 2019), —to which the applicant can respond with an amendment or rebuttal.

An example timeline of obtaining patent protection on an invention in the United States, including only basic events and milestones.

After the applicant and the examiner arrive at an allowable set of claims, and the application is otherwise compliant with the requirements of U.S. patent law, the application may be allowed. The issue fee must then be paid and, if a patent issues, maintenance fees must be paid at regular intervals.

This is a basic, high-level overview of what can be a complicated process with many deadlines and requirements. It’s always best to consult with a qualified patent practitioner having an understanding of the field of your invention.

Bonus fun fact: Patent applications are generally published on Thursdays and patent grants are published on Tuesdays.
