What this shows Daiwa's Innovation Score is 33.6/100 (45th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Daiwa?

Each dot is one of Daiwa’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Daiwa’s own 3.6 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Daiwa's grants concentrate

Daiwa Kasei Kogyo Kabushiki Kaisha is a focused PatentsView assignee: 13 CPC subclasses with 32.6% of grants classified under F16B (Devices FOR Fastening OR Securing Constructional Elements OR Machine Parts Together, e.g. Nails, Bolts, Circlips, Clamps, Clips OR WEDGES; Joints OR Jointing). Peak complete grant year is 2017 (13 grants) versus a trough of 1 in 2021. By volume, Daiwa sits between China University of Geosciences and Edsal Manufacturing Company, LLC.

Daiwa's three-year grant acceleration

Daiwa Kasei Kogyo Kabushiki Kaisha shows 5 grants in 2022–2024 against only 6 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
