USPTO PatentsView assignee record - 10 granted patents across 8 technology areas, active 2017–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H04N (PICTORIAL COMMUNICATION, e.g. TELEVISION).
The verdict
Guangzhou holds 10 US patents across 8 technology areas, rank #26,382 of 50,000 tracked assignees.
Guangzhou Huaduo Network Technology Co., Ltd. has been granted 10 US utility patents between 2017 and 2025, placing Guangzhou Huaduo Network Technology Co., Ltd. at rank #26,382 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.9 claims per patent with primary concentration in H04N (PICTORIAL COMMUNICATION, e.g. TELEVISION). As a Foreign Corporation, Guangzhou Huaduo Network Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Guangzhou sits between GTI Energy (10 patents, rank #26,378) and GWO XI STEM CELL Applied Technology Co., Ltd. (10 patents, rank #26,386) - the closest US assignees by grant volume. The composite Innovation Score of 35.5/100 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 7 grants, compared with 3 in the 2015–2019 window, a +133% 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. Guangzhou Huaduo Network Technology Co., Ltd.'s 13.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Guangzhou Huaduo Network Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Guangzhou's 10 grants land it in the top 49% 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.
