What this shows Youlchon's Innovation Score is 43.0/100 (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 Youlchon?

Each dot is one of Youlchon’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). Youlchon’s own 12.2 claims/patent is at or below the 14.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Youlchon's grants concentrate

Youlchon Chemical Co., Ltd. is a focused PatentsView assignee: 22 CPC subclasses with 53.8% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2015 (5 grants) versus a trough of 1 in 2016. By volume, Youlchon sits between Yushin Co., Ltd. and Zero Motorcycles, Inc..

Youlchon's three-year grant acceleration

Youlchon Chemical Co., Ltd. shows 3 grants in 2022–2024 against only 2 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.
