The United States Patent and Trademark Office (USPTO) was created to make it possible for people to get a patent on their own without the assistance of a lawyer. You may draught your own patent, submit it, and pay the filing costs. Is this process free? No. You will always be required to pay filing costs to have your patent evaluated and issue fees after it has been approved.
