The University of California has once again topped a nationwide ranking of schools with the most utility patents.

UC Berkeley and UCLA tied for the best public university in the country, with six University of California undergraduate campuses among the top 20 and all nine in the top 40.

Four UC campuses are among the top 25 of all private or public universities in the country, says Forbes.

UC’s 10 campuses earned stellar rankings across six disciplines this year, featuring some of the country’s best programs and most highly-regarded schools.
