What this shows Chong's Innovation Score is 35.5/100 (top 49% 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 Chong?

Each dot is one of Chong’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). Chong’s own 9.8 claims/patent is at or below the 18.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chong's grants concentrate

Chong KUN Dang Pharmaceutical Corp. is a focused PatentsView assignee: 11 CPC subclasses with 80.6% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2016 (6 grants) versus a trough of 1 in 2015. By volume, Chong sits between Brose Schließsysteme GmbH & Co. Kommanditgesellschaft and Cradlepoint, Inc..

Chong's three-year grant acceleration

Chong KUN Dang Pharmaceutical Corp. shows 9 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.
