Filing a patent application on your own

Pro Se Assistance Program

The patent process is a complex set of laws, regulations, policies and procedures; therefore, the USPTO always recommends using a registered patent attorney or agent to assist in preparing your application. The USPTO also recognizes that the cost of legal assistance is prohibitive for many applicants, particularly independent inventors and small businesses. The Pro Se Assistance Program is dedicated to help independent inventors and small businesses meet their goal of protecting valuable intellectual property.

The Pro Se Assistance Program provides outreach and education to applicants (also known as "pro se" applicants) who file patent applications without the assistance of a registered patent attorney or agent. USPTO employees cannot give legal advice. However, through increased assistance and resources for independent inventor and small business communities, the program aims to increase the quality of pro se applications and assist pro se applicants with making informed decisions regarding their patent applications.

Why is educating yourself about intellectual property protection important?

Intellectual property protection is critical to safeguard products and services from imitation, attract and secure funding from outside investors and promote the overall commercial success of any enterprise. In addition, the value of a patent is largely dependent upon skilled preparation and prosecution. Educating yourself is an important first step to develop an intellectual property strategy that can yield substantial economic benefits for your company and endeavors.
