What this shows Young's Innovation Score is 38.0/100 (top 42% 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 Young?

Each dot is one of Young’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). Young’s own 6.3 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Young's grants concentrate

Young Chang Chemical Co., Ltd is a focused PatentsView assignee: 17 CPC subclasses with 65.5% of grants classified under G03F (Photomechanical Production OF Textured OR Patterned Surfaces, e.g. FOR Printing, FOR Processing OF Semiconductor DEVICES; Materials THEREFOR; Originals THEREFOR; Apparatus Specially Adapted THEREFOR;). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2017. By volume, Young sits between Wolf Appliance, Inc. and Zipline International Inc..

Young's three-year grant acceleration

Young Chang Chemical Co., Ltd shows 13 grants in 2022–2024 against only 11 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.
