What this shows DAI's Innovation Score is 44.0/100 (top 27% 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 DAI?

Each dot is one of DAI’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). DAI’s own 9.4 claims/patent is at or below the 13.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where DAI's grants concentrate

DAI Nippon Toryo Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 85.7% of grants classified under C09D (Coating Compositions, e.g. Paints, Varnishes OR LACQUERS; Filling PASTES; Chemical Paint OR INK REMOVERS; INKS; Correcting FLUIDS; WOODSTAINS; Pastes OR Solids FOR Colouring OR PRINTING; USE OF Materi). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2018. By volume, DAI sits between Daegu-gyeongbuk Medical Innovation Foundation and Datchat, Inc..

DAI's three-year grant acceleration

DAI Nippon Toryo Co., Ltd. shows 4 grants in 2022–2024 against only 0 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.
