USPTO PatentsView assignee record - 7 granted patents across 9 technology areas, active 2020–2022. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F16M (FRAMES, CASINGS OR BEDS OF ENGINES, MACHINES OR APPARATUS, NOT SPECIFIC TO ENGINES, MACHINES OR APPARATUS PROVIDED FOR ELSEWHERE; STANDS; SUPPORTS).
The verdict
Shenzhen holds 7 US patents across 9 technology areas, rank #37,591 of 50,000 tracked assignees.
Shenzhen Hongfei Precision Technology Co., Ltd. has been granted 7 US utility patents between 2020 and 2022, placing Shenzhen Hongfei Precision Technology Co., Ltd. at rank #37,591 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.7 claims per patent with primary concentration in F16M (FRAMES, CASINGS OR BEDS OF ENGINES, MACHINES OR APPARATUS, NOT SPECIFIC TO ENGINES, MACHINES OR APPARATUS PROVIDED FOR ELSEWHERE; STANDS; SUPPORTS). As a Foreign Corporation, Shenzhen Hongfei Precision Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shenzhen sits between Shannon Specialty Floors, Inc. (7 patents, rank #37,587) and Shenzhen Baishanchuan Technology Co., Ltd (7 patents, rank #37,595) - the closest US assignees by grant volume. The composite Innovation Score of 24.7/100 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. Historical data spans 2020 through 2022, with 7 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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 Hongfei Precision Technology Co., Ltd.'s 9.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shenzhen Hongfei Precision Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Shenzhen's 7 grants land it in the top 85% 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.
