Overall rank by patents
#1,532
Across all tracked assignees
USPTO PatentsView assignee record — 272 granted patents across 131 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: E21F (SAFETY DEVICES, TRANSPORT, FILLING-UP, RESCUE, VENTILATION, OR DRAINING IN OR OF MINES OR TUNNELS).
China University of Mining and Technology has been granted 272 US utility patents between 2015 and 2025, placing China University of Mining and Technology at rank #1,532 across all assignees tracked by PlainPatent. This portfolio spans 131 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.5 claims per patent with primary concentration in E21F (SAFETY DEVICES, TRANSPORT, FILLING-UP, RESCUE, VENTILATION, OR DRAINING IN OR OF MINES OR TUNNELS). As a Foreign Corporation, China University of Mining and Technology is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 52.5/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 183 grants, compared with 89 in the 2015–2019 window — a +106% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. China University of Mining and Technology's 6.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark China University of Mining and Technology against peers pursuing similar technology classes.
