Portfolio overview

Nitto Kogyo Corporation has been granted 6 US utility patents between 2015 and 2025, placing Nitto Kogyo Corporation at rank #41,887 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.0 claims per patent with primary concentration in G01R (MEASURING ELECTRIC VARIABLES; MEASURING MAGNETIC VARIABLES). As a Foreign Corporation, Nitto Kogyo Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Nitto sits between Nippon Steel & Sumikin Hardfacing Co., Ltd. (6 patents, rank #41,883) and Noark Electrics(shanghai) Co., Ltd. (6 patents, rank #41,891) - the closest US assignees by grant volume. The composite Innovation Score of 30.5/100 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 4 grants, compared with 2 in the 2015–2019 window, a +100% 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. Nitto Kogyo Corporation's 9.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nitto Kogyo Corporation against peers pursuing similar technology classes.
