Portfolio overview
ZHEJIANG DAHUA TECHNOLOGY CO., LTD. has been granted 217 US utility patents between 2016 and 2025, placing ZHEJIANG DAHUA TECHNOLOGY CO., LTD. at rank #1,860 across all assignees tracked by PlainPatent. This portfolio spans 52 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.4 claims per patent with primary concentration in H04N (PICTORIAL COMMUNICATION, e.g. TELEVISION). As a Foreign Corporation, ZHEJIANG DAHUA TECHNOLOGY CO., LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 70.6/100 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 206 grants, compared with 11 in the 2015–2019 window — a +1773% 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. ZHEJIANG DAHUA TECHNOLOGY CO., LTD.'s 17.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 52 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ZHEJIANG DAHUA TECHNOLOGY CO., LTD. against peers pursuing similar technology classes.
