Portfolio overview

Shenzhen Qianhai Livall IOT Technology Co., Ltd. has been granted 10 US utility patents between 2018 and 2021, placing Shenzhen Qianhai Livall IOT Technology Co., Ltd. at rank #27,336 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.4 claims per patent with primary concentration in A42B (HATS; HEAD COVERINGS). As a Foreign Corporation, Shenzhen Qianhai Livall IOT Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shenzhen sits between Shenzhen Jianan Technology Co., Limited (10 patents, rank #27,332) and Shenzhen VMAX NEW Energy Co., Ltd. (10 patents, rank #27,340) - the closest US assignees by grant volume. The composite Innovation Score of 24.3/100 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 1 grants, compared with 9 in the 2015–2019 window, a -89% 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. Shenzhen Qianhai Livall IOT Technology Co., Ltd.'s 5.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shenzhen Qianhai Livall IOT Technology Co., Ltd. against peers pursuing similar technology classes.

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.
