Portfolio overview

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. 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.
