Portfolio overview

Arakawa Chemical Industries, Ltd. has been granted 25 US utility patents between 2015 and 2025, placing Arakawa Chemical Industries, Ltd. at rank #11,904 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.8 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Arakawa Chemical Industries, Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Arakawa sits between Apator Miitors APS (25 patents, rank #11,900) and Asmpt Singapore PTE. Ltd. (25 patents, rank #11,908) - the closest US assignees by grant volume. The composite Innovation Score of 53.3/100 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 13 grants, compared with 12 in the 2015–2019 window, a +8% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Arakawa Chemical Industries, Ltd.'s 7.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Arakawa Chemical Industries, Ltd. against peers pursuing similar technology classes.
