USPTO PatentsView assignee record - 5 granted patents across 1 technology areas, active 2022–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F01L (CYCLICALLY OPERATING VALVES FOR MACHINES OR ENGINES).
The verdict
Jiangsu holds 5 US patents across 1 technology areas, rank #47,933 of 50,000 tracked assignees.
Jiangsu Jointek Precision Machinery Co., Ltd. has been granted 5 US utility patents between 2022 and 2024, placing Jiangsu Jointek Precision Machinery Co., Ltd. at rank #47,933 across all assignees tracked by PlainPatent. This portfolio spans 1 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.0 claims per patent with primary concentration in F01L (CYCLICALLY OPERATING VALVES FOR MACHINES OR ENGINES). As a Foreign Corporation, Jiangsu Jointek Precision Machinery Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Jiangsu sits between Jiangsu Burgeree NEW Technology Materials Co., Ltd. (5 patents, rank #47,929) and Jiangsu Sainty Sumex Tools Corp. Ltd. (5 patents, rank #47,937) - the closest US assignees by grant volume. The composite Innovation Score of 38.1/100 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 2024, with 5 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. Jiangsu Jointek Precision Machinery Co., Ltd.'s 14.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 1 subclass reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Jiangsu Jointek Precision Machinery Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Jiangsu's 5 grants land it in the top 42% 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.
