Jiwei (ijiwei.com) has conducted a comprehensive analysis of 27 listed companies' disclosures of invention patents in 2020, the number of invention patents granted, the number of utility model grants, and the proportion of published and authorized patents in 2020 in the total number of corporate patents.

Jiwei patent analysis experts have comprehensively studied the patent situation of listed Chinese semiconductor materials companies in 2020 and found that semiconductor materials concept companies have achieved certain results in innovation and patent output. However, the gap with foreign semiconductor giants is still relatively noticeable.

The overall performance shows as:

First, the patent activity is low, and the number of patents is generally low;

second, the layout of patents is limited to China, lacking a global vision;

third, the quality of patents is inadequate and lacks international competitiveness;

fourth, the critical materials insufficient in innovation; the third-generation semiconductor materials are significantly insufficient.
