USPTO PatentsView assignee record - 131 granted patents across 3 technology areas, active 2018–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR CURRENTS FOR SCREENING).
The verdict
Shenzhen holds 131 US patents across 3 technology areas, rank #2,916 of 50,000 tracked assignees.
Shenzhen Qianhai Patuoxun Network AND Technology Co., Ltd. has been granted 131 US utility patents between 2018 and 2024, placing Shenzhen Qianhai Patuoxun Network AND Technology Co., Ltd. at rank #2,916 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.2 claims per patent with primary concentration in F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR CURRENTS FOR SCREENING). As a Foreign Corporation, Shenzhen Qianhai Patuoxun Network AND Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shenzhen sits between Epoch Company, Ltd. (131 patents, rank #2,912) and St. Jude Medical, Llc (131 patents, rank #2,920) - the closest US assignees by grant volume. The composite Innovation Score of 25.4/100 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 107 grants, compared with 24 in the 2015–2019 window, a +346% 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. Shenzhen Qianhai Patuoxun Network AND Technology Co., Ltd.'s 1.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shenzhen Qianhai Patuoxun Network AND Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Shenzhen's 131 grants land it in the top 83% 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.
