USPTO PatentsView assignee record - 499 granted patents across 240 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G06F (ELECTRIC DIGITAL DATA PROCESSING).
The verdict
Dalian holds 499 US patents across 240 technology areas, rank #900 of 50,000 tracked assignees.
Dalian University Of Technology has been granted 499 US utility patents between 2015 and 2025, placing Dalian University Of Technology at rank #900 across all assignees tracked by PlainPatent. This portfolio spans 240 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.3 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Government, Dalian University Of Technology is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Dalian sits between Airbus Helicopters (501 patents, rank #896) and University OF Maryland, Baltimore (497 patents, rank #904) - the closest US assignees by grant volume. The composite Innovation Score of 60.3/100 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 442 grants, compared with 57 in the 2015–2019 window, a +675% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Government 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. Dalian University Of Technology's 5.3 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 Dalian University Of Technology against peers pursuing similar technology classes.

How to use this portfolio
Dalian's 499 grants land it in the top 3% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
