USPTO PatentsView assignee record - 9 granted patents across 2 technology areas, active 2017–2023. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G05D (SYSTEMS FOR CONTROLLING OR REGULATING NON-ELECTRIC VARIABLES).
The verdict
Guangzhou holds 9 US patents across 2 technology areas, rank #28,851 of 50,000 tracked assignees.
Guangzhou Ehang Intelligent Technology Co., Ltd. has been granted 9 US utility patents between 2017 and 2023, placing Guangzhou Ehang Intelligent Technology Co., Ltd. at rank #28,851 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 2.9 claims per patent with primary concentration in G05D (SYSTEMS FOR CONTROLLING OR REGULATING NON-ELECTRIC VARIABLES). As a Foreign Corporation, Guangzhou Ehang Intelligent Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Guangzhou sits between Group IB, Ltd (9 patents, rank #28,847) and Guangzhou Yajiang Photoelectric Equipment Co., Ltd. (9 patents, rank #28,855) - the closest US assignees by grant volume. The composite Innovation Score of 18.0/100 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 2 grants, compared with 7 in the 2015–2019 window, a -71% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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 Ehang Intelligent Technology Co., Ltd.'s 2.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Guangzhou Ehang Intelligent Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Guangzhou's 9 grants land it in the top 95% 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.
