USPTO PatentsView assignee record - 10 granted patents across 4 technology areas, active 2024–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A24F (SMOKERS' REQUISITES; MATCH BOXES; SIMULATED SMOKING DEVICES).
The verdict
Shenzhen holds 10 US patents across 4 technology areas, rank #27,330 of 50,000 tracked assignees.
Shenzhen Huachengda Precision Industry Co. Ltd. has been granted 10 US utility patents between 2024 and 2025, placing Shenzhen Huachengda Precision Industry Co. Ltd. at rank #27,330 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in A24F (SMOKERS' REQUISITES; MATCH BOXES; SIMULATED SMOKING DEVICES). As a Foreign Corporation, Shenzhen Huachengda Precision Industry Co. Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shenzhen sits between Shenzhen Diepin Technology Co., Ltd. (10 patents, rank #27,326) and Shenzhen Ocean's KING Lighting Engineering Co., Ltd. (10 patents, rank #27,334) - the closest US assignees by grant volume. The composite Innovation Score of 45.3/100 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. Historical data spans 2024 through 2025, with 10 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 Huachengda Precision Industry Co. Ltd.'s 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shenzhen Huachengda Precision Industry Co. Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Shenzhen's 10 grants land it in the top 23% 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.
