Portfolio overview

OTSUKA CHEMICAL CO., LTD. has been granted 49 US utility patents between 2015 and 2025, placing OTSUKA CHEMICAL CO., LTD. at rank #6,823 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.3 claims per patent with primary concentration in C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). As a Foreign Corporation, OTSUKA CHEMICAL CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 47.6/100 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 28 grants, compared with 21 in the 2015–2019 window — a +33% 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. OTSUKA CHEMICAL CO., LTD.'s 9.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark OTSUKA CHEMICAL CO., LTD. against peers pursuing similar technology classes.
