According to the 2017 patent statistics released by the State Intellectual Property Office of the People's Republic of China, the overall situation of China’s invention patents is good, but there is a clear differentiation between regions. The provinces of Guangdong, Jiangsu, and Zhejiang have the largest number of patent authorizations in China, and the number of invention patents is also in the lead. More than 100,000 pieces, while the amount of patented inventions and possessions in the northwest and southwestern provinces is at a low level.
From the perspective of colleges and universities, Zhejiang University, Harbin Institute of Technology and Tsinghua University ranked 1951, 1576, and 1,506 patent grants respectively. The top ten colleges and universities with patents for inventions are known for their science and engineering disciplines.
