Portfolio overview

TOSOH FINECHEM CORPORATION has been granted 22 US utility patents between 2015 and 2024, placing TOSOH FINECHEM CORPORATION at rank #13,731 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.9 claims per patent with primary concentration in C07F (ACYCLIC, CARBOCYCLIC OR HETEROCYCLIC COMPOUNDS CONTAINING ELEMENTS OTHER THAN CARBON, HYDROGEN, HALOGEN, OXYGEN, NITROGEN, SULFUR, SELENIUM OR TELLURIUM). As a Foreign Corporation, TOSOH FINECHEM CORPORATION is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 53.0/100 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 16 grants, compared with 6 in the 2015–2019 window, a +167% 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. TOSOH FINECHEM CORPORATION's 11.9 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 TOSOH FINECHEM CORPORATION against peers pursuing similar technology classes.

How to use this portfolio

Tosoh's 22 grants land it in the top 9% by Innovation Score, but volume alone doesn't tell you where the strength sits.
