USPTO PatentsView assignee record - 6 granted patents across 9 technology areas, active 2022–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A47J (KITCHEN EQUIPMENT; COFFEE MILLS; SPICE MILLS; APPARATUS FOR MAKING BEVERAGES).
The verdict
Jiangmen holds 6 US patents across 9 technology areas, rank #41,109 of 50,000 tracked assignees.
Jiangmen Yishan Metal Products Co., Ltd. has been granted 6 US utility patents between 2022 and 2025, placing Jiangmen Yishan Metal Products Co., Ltd. at rank #41,109 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.2 claims per patent with primary concentration in A47J (KITCHEN EQUIPMENT; COFFEE MILLS; SPICE MILLS; APPARATUS FOR MAKING BEVERAGES). As a Foreign Corporation, Jiangmen Yishan Metal Products Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Jiangmen sits between Jensen Enterprises, Inc. (6 patents, rank #41,105) and Jinhua Gica Baby Products Co., Ltd. (6 patents, rank #41,113) - the closest US assignees by grant volume. The composite Innovation Score of 33.2/100 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 2022 through 2025, with 6 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. Jiangmen Yishan Metal Products Co., Ltd.'s 4.2 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 Jiangmen Yishan Metal Products Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Jiangmen's 6 grants land it in the top 57% 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.
