What this shows Kukdo's Innovation Score is 44.4/100 (top 26% 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 Kukdo?

Each dot is one of Kukdo’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). Kukdo’s own 11.8 claims/patent is at or below the 12.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kukdo's grants concentrate

Kukdo Chemical Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 83.3% of grants classified under C08G (Macromolecular Compounds Obtained Otherwise Than BY Reactions Only Involving Unsaturated Carbon-to-carbon Bonds). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2020. By volume, Kukdo sits between Kryo, Inc. and Kuraray Chemical Co., Ltd..

Kukdo's three-year grant acceleration

Kukdo Chemical Co., Ltd. shows 3 grants in 2022–2024 against only 1 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.
