Portfolio overview
KITAGAWA INDUSTRIES CO., LTD. has been granted 84 US utility patents between 2015 and 2025, placing KITAGAWA INDUSTRIES CO., LTD. at rank #4,248 across all assignees tracked by PlainPatent. This portfolio spans 52 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.3 claims per patent with primary concentration in H05K (PRINTED CIRCUITS; CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS). As a Foreign Corporation, KITAGAWA INDUSTRIES CO., LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 48.5/100 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. Between 2020 and 2025 the company received 34 grants, compared with 50 in the 2015–2019 window — a -32% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. KITAGAWA INDUSTRIES CO., LTD.'s 8.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 52 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KITAGAWA INDUSTRIES CO., LTD. against peers pursuing similar technology classes.
