What this shows Heesung's Innovation Score is 40.4/100 (top 36% 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 Heesung?

Each dot is one of Heesung’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). Heesung’s own 8.6 claims/patent is at or below the 9.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Heesung's grants concentrate

Heesung Catalysts Corporation is a focused PatentsView assignee: 15 CPC subclasses with 96.9% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2016 (7 grants) versus a trough of 1 in 2017. By volume, Heesung sits between Gruppo Cimbali S.p.A. and Halliburton Manufacturing and Services Limited.

Heesung's three-year grant acceleration

Heesung Catalysts Corporation shows 10 grants in 2022–2024 against only 7 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.
