What this shows Daicel-evonik's Innovation Score is 43.8/100 (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 Daicel-evonik?

Each dot is one of Daicel-evonik’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). Daicel-evonik’s own 11.4 claims/patent is at or below the 13.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Daicel-evonik's grants concentrate

Daicel-evonik Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 61.9% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2015. By volume, Daicel-evonik sits between Curiteva, Inc. and Dehn SE + Co KG.

Daicel-evonik's three-year grant acceleration

Daicel-evonik Ltd. shows 9 grants in 2022–2024 against only 7 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.
