If you qualify for free legal assistance with your patent application (income 300% or less of Federal Poverty Guidelines), there is an office in Florida that provides free Pro Bono Assistance. There is a USPTO video series available that explains the program fully.
The USPTO maintains a roster of patent agents and attorneys who are authorized to practice before the United States Patent and Trademark Office. You may use their database (search or download) to obtain the most current information on practitioners in your city, county or zip code.
Staffed by former Supervisory Patent Examiners and experienced Primary Examiners, the Inventors Assistance Center (IAC) answers questions concerning patent examining policy and procedure .
