Across all tracked assignees
USPTO PatentsView assignee record - 10 granted patents across 4 technology areas, active 2023–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B60B (VEHICLE WHEELS ; CASTORS; AXLES FOR WHEELS OR CASTORS; INCREASING WHEEL ADHESION).
The verdict
Shanghai holds 10 US patents across 4 technology areas, rank #27,317 of 50,000 tracked assignees.
Shanghai Linghuo Trading Co., Ltd. has been granted 10 US utility patents between 2023 and 2024, placing Shanghai Linghuo Trading Co., Ltd. at rank #27,317 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.0 claims per patent with primary concentration in B60B (VEHICLE WHEELS ; CASTORS; AXLES FOR WHEELS OR CASTORS; INCREASING WHEEL ADHESION). As a Foreign Corporation, Shanghai Linghuo Trading Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shanghai sits between SFC Global Supply Chain, Inc. (10 patents, rank #27,313) and SHEN ZHEN Stand BY ME Technology Limited (10 patents, rank #27,321) - the closest US assignees by grant volume. The composite Innovation Score of 47.4/100 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. Historical data spans 2023 through 2024, 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. Shanghai Linghuo Trading Co., Ltd.'s 20.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shanghai Linghuo Trading Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Shanghai's 10 grants land it in the top 19% 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.
