We signed up for the Pro Bono patent program. The ProBoPat program connects low-income inventors with patent practitioners for patent preparation and prosecution legal services on a pro bono (free) basis as well as provides access to business consulting and training for bringing new ideas to market.
Our ProBoPat provided is Mi Casa Resource Center. Eligible applicants are residents of Colorado, Montana, New Mexico, Utah, or Wyoming who have an annual income of three times the federal poverty guidelines or less and who, in ProBoPat’s sole discretion, would benefit from the program.
If you don't live in one of these States, not problem. You can find the closest one to you at the United States Patent and Trademark Office (USPTO).
