It can cost thousands of dollars in legal fees and other expenses to secure a patent; however, for $6 an inventor can file a “disclosure document”.
This document can be filed with the U.S. patent and trademark office.
Moreover, this procedure will protect the patent for two (2) years, while the patent is being worked on.
The document is destroyed if no patent is filed at the end of two years.
To file, send an 8 1/2 x 13-inch drawing, a copy, signed disclosure statement, self-addressed, stamped envelope, and a check for $6 to:
Disclosure Statement, Commissioner of Patents and Trademarks, Washington, DC 20231
