What this shows Yong's Innovation Score is 47.0/100 (top 20% 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 Yong?

Each dot is one of Yong’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). Yong’s own 13.4 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yong's grants concentrate

Yong San Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 42.9% of grants classified under B60J (Windows, Windscreens, Non-fixed Roofs, Doors, OR Similar Devices FOR VEHICLES; Removable External Protective Coverings Specially Adapted FOR Vehicles). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2021. By volume, Yong sits between Yield10 Bioscience, Inc. and Yulan Green Technology Co., Ltd..

Yong's three-year grant acceleration

Yong San Co., Ltd. shows 6 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.
