Portfolio overview
Dongguan University of Technology has been granted 56 US utility patents between 2017 and 2025, placing Dongguan University of Technology at rank #6,018 across all assignees tracked by PlainPatent. This portfolio spans 101 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.9 claims per patent with primary concentration in B23P (METAL-WORKING NOT OTHERWISE PROVIDED FOR; COMBINED OPERATIONS; UNIVERSAL MACHINE TOOLS). As a Foreign Corporation, Dongguan University of Technology is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 48.3/100 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 51 grants, compared with 5 in the 2015–2019 window — a +920% 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. Dongguan University of Technology's 9.9 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 Dongguan University of Technology against peers pursuing similar technology classes.
