Portfolio overview

EIKEN KAGAKU KABUSHIKI KAISHA has been granted 26 US utility patents between 2015 and 2025, placing EIKEN KAGAKU KABUSHIKI KAISHA at rank #11,630 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.0 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, EIKEN KAGAKU KABUSHIKI KAISHA is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 37.8/100 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 15 grants, compared with 11 in the 2015–2019 window, a +36% 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. EIKEN KAGAKU KABUSHIKI KAISHA's 9.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark EIKEN KAGAKU KABUSHIKI KAISHA against peers pursuing similar technology classes.
