USPTO PatentsView assignee record - 326 granted patents across 44 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H04N (PICTORIAL COMMUNICATION, e.g. TELEVISION).
The verdict
Hangzhou holds 326 US patents across 44 technology areas, rank #1,296 of 50,000 tracked assignees.
Hangzhou Hikvision Digital Technology Co., Ltd. has been granted 326 US utility patents between 2015 and 2025, placing Hangzhou Hikvision Digital Technology Co., Ltd. at rank #1,296 across all assignees tracked by PlainPatent. This portfolio spans 44 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.2 claims per patent with primary concentration in H04N (PICTORIAL COMMUNICATION, e.g. TELEVISION). As a Foreign Corporation, Hangzhou Hikvision Digital Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Hangzhou sits between Brother Industries, Ltd. (327 patents, rank #1,292) and SICK Ag (326 patents, rank #1,300) - the closest US assignees by grant volume. The composite Innovation Score of 56.1/100 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 268 grants, compared with 58 in the 2015–2019 window, a +362% 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. Hangzhou Hikvision Digital Technology Co., Ltd.'s 12.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 44 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hangzhou Hikvision Digital Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Hangzhou's 326 grants land it in the top 6% 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.
