If you've invented something and want to patent it but can't afford a patent attorney, the California Inventors Assistance Program (CIAP) matches you with a volunteer patent attorney for free. It's run by California Lawyers for the Arts (CLA) under the USPTO's nationwide Patent Pro Bono Program.
Who qualifies
- You live in California (or Hawaii, Alaska, Oregon, or Nevada — CIAP covers all five states).
- Your gross household income is less than 3× the federal poverty level. For 2026 that's roughly $47,880/year for one person or $99,000/year for a family of four [Source: aspe.hhs.gov/topics/poverty-economic-mobility/poverty-guidelines (accessed 2026-05-17)].
- You have an actual invention you can describe (not just an idea).
- You can show basic knowledge of the patent system — the program requires you to watch a short USPTO training video first (see below).
What you get
- A volunteer patent attorney who handles your patent matter with legal fees waived.
- Help preparing and filing a patent application with the USPTO.
What it does NOT cover: USPTO filing fees, search fees, copying costs, and similar out-of-pocket expenses. You pay those yourself. The attorney won't pay them for you [Source: calawyersforthearts.org/california-inventors-assistance-program-ciap-cla/ (accessed 2026-05-17)].
How to apply
- Watch the free USPTO training video. It's 39 minutes, 30 short modules, called Basic Patent Training for Independent Inventors and Small Businesses. You must finish it before CIAP will match you with an attorney. Find it on uspto.gov by searching "Patent Pro Bono training."
- Fill out the CIAP Referral Request form at cla.formstack.com/forms/cla_lawyer_referral_request.
- Submit financial documents (tax return, pay stubs, or benefits paperwork) so CLA can confirm you meet the income limit.
- Wait for a match. CLA reviews your application and refers you to a volunteer attorney. Timing varies depending on attorney availability.
Common pitfalls
- Don't publicly disclose your invention before applying for a patent. Selling it, showing it at a trade show, or posting about it online can hurt your ability to get a patent.
- Budget for filing fees. USPTO micro-entity filing fees for a basic utility patent start around a few hundred dollars and can add up. Ask the attorney what to expect.
- Have a real invention, not just an idea. You need to describe how it works, not just what it does.
- Be honest about income. CIAP verifies financial information; misrepresenting it disqualifies you.
