Unicamp is responsible for around 15% of Brazilian research, a disproportionately high number when compared to much larger and older institutions in the country such as the University of São Paulo. It also produces more patents than any other research organization in Brazil, being second only to the state-owned oil company, Petrobras. Multiple international university rankings place it amongst the best universities in the world, with QS placing it in the Top 200 globally and ranking it the 11th best university under 50 years, and in 2015 it was rated as the best university in the country by Brazil's Ministry of Education.
