Portfolio overview

DAIWA KASEI KOGYO KABUSHIKI KAISHA has been granted 43 US utility patents between 2015 and 2025, placing DAIWA KASEI KOGYO KABUSHIKI KAISHA at rank #7,546 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 3.6 claims per patent with primary concentration in F16B (DEVICES FOR FASTENING OR SECURING CONSTRUCTIONAL ELEMENTS OR MACHINE PARTS TOGETHER, e.g. NAILS, BOLTS, CIRCLIPS, CLAMPS, CLIPS OR WEDGES; JOINTS OR JOINTING). As a Foreign Corporation, DAIWA KASEI KOGYO KABUSHIKI KAISHA is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 33.6/100 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 12 grants, compared with 31 in the 2015–2019 window — a -61% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. DAIWA KASEI KOGYO KABUSHIKI KAISHA's 3.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark DAIWA KASEI KOGYO KABUSHIKI KAISHA against peers pursuing similar technology classes.
