Portfolio overview

DENKA COMPANY LIMITED has been granted 359 US utility patents between 2016 and 2025, placing DENKA COMPANY LIMITED at rank #1,186 across all assignees tracked by PlainPatent. This portfolio spans 118 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in C08L (COMPOSITIONS OF MACROMOLECULAR COMPOUNDS). As a Foreign Corporation, DENKA COMPANY LIMITED is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 61.5/100 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 246 grants, compared with 113 in the 2015–2019 window — a +118% 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. DENKA COMPANY LIMITED's 9.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark DENKA COMPANY LIMITED against peers pursuing similar technology classes.
