Portfolio overview
KAWASAKI RAILCAR MANUFACTURING CO., LTD. has been granted 19 US utility patents between 2022 and 2025, placing KAWASAKI RAILCAR MANUFACTURING CO., LTD. at rank #15,402 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.6 claims per patent with primary concentration in B61F (RAIL VEHICLE SUSPENSIONS, e.g. UNDERFRAMES, BOGIES OR ARRANGEMENTS OF WHEEL AXLES; RAIL VEHICLES FOR USE ON TRACKS OF DIFFERENT WIDTH; PREVENTING DERAILING OF RAIL VEHICLES; WHEEL GUARDS, OBSTRUCTION ). As a Foreign Corporation, KAWASAKI RAILCAR MANUFACTURING CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 52.9/100 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 19 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. KAWASAKI RAILCAR MANUFACTURING CO., LTD.'s 10.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KAWASAKI RAILCAR MANUFACTURING CO., LTD. against peers pursuing similar technology classes.
