Portfolio overview
KOITO ELECTRIC INDUSTRIES, LTD has been granted 21 US utility patents between 2019 and 2025, placing KOITO ELECTRIC INDUSTRIES, LTD at rank #14,091 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.3 claims per patent with primary concentration in B61D (BODY DETAILS OR KINDS OF RAILWAY VEHICLES). As a Foreign Corporation, KOITO ELECTRIC INDUSTRIES, LTD is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 43.1/100 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. Between 2020 and 2025 the company received 19 grants, compared with 2 in the 2015–2019 window — a +850% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. KOITO ELECTRIC INDUSTRIES, LTD's 6.3 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 KOITO ELECTRIC INDUSTRIES, LTD against peers pursuing similar technology classes.
