California inventors with limited resources to pay big-firm legal bills can look forward to the Oct. 23 launch of a U.S. Patent and Trademark Office-backed pro bono patent program.

The California Inventors Assistance Program, which was announced Monday, will give pro bono patenting help to individuals and businesses. The program stems from a mandate in the America Invents Act to establish regional pro bono centers for inventors and entrepreneurs. It follows similar programs in Minnesota, launched in June 2011, and Colorado, which started this past April.
