Portfolio overview

Jiangsu Kangrui New Material Technology Co., Ltd. has been granted 9 US utility patents between 2021 and 2025, placing Jiangsu Kangrui New Material Technology Co., Ltd. at rank #29,151 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.8 claims per patent with primary concentration in B24B (MACHINES, DEVICES, OR PROCESSES FOR GRINDING OR POLISHING ; DRESSING OR CONDITIONING OF ABRADING SURFACES; FEEDING OF GRINDING, POLISHING, OR LAPPING AGENTS). As a Foreign Corporation, Jiangsu Kangrui New Material Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Jiangsu sits between Jenoptik Advanced Systems Gmbh (9 patents, rank #29,147) and Jsyard Home Technology Co., Ltd (9 patents, rank #29,155) - the closest US assignees by grant volume. The composite Innovation Score of 51.7/100 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 2021 through 2025, with 9 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 Kangrui New Material Technology Co., Ltd.'s 16.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Jiangsu Kangrui New Material Technology Co., Ltd. against peers pursuing similar technology classes.

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.
