What this shows Woori's Innovation Score is 43.1/100 (top 29% 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 Woori?

Each dot is one of Woori’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). Woori’s own 8.6 claims/patent is at or below the 9.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Woori's grants concentrate

Woori Fine Chem Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under C07C (Acyclic OR Carbocyclic Compounds). Peak complete grant year is 2024 (5 grants) versus a trough of 2 in 2022. By volume, Woori sits between Wilton Industries, Inc. and Wagner Group GmbH.

Woori's three-year grant acceleration

Woori Fine Chem Co., Ltd. shows 11 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.
