Company patents
JIANGSU UNIVERSITY
Jiangsu University's patent strategy shows a surprising shift away from several key manufacturing and electrical power categories, with Welding & Soldering, Electric Motors & Generators, Gearing & Transmissions, and Motor Control all seeing a 100% decline in patenting activity so far in 2026. While Material & Chemical Analysis remains its largest category at 14.9% of its portfolio, the university is also demonstrating an emerging focus on Electronic Design Automation (CAD/EDA), which saw a 50% increase in patents so far in 2026, contrasting with a general decline across many other areas.
