What this shows ST's Innovation Score is 33.7/100 (45th percentile 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 ST?

Each dot is one of ST’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). ST’s own 11.5 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where ST's grants concentrate

ST Pharm Co., Ltd. is a focused PatentsView assignee: 17 CPC subclasses with 58.8% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2015. By volume, ST sits between Sortera Technologies, Inc. and Stanley Fastening Systems, L.P..

ST's three-year grant acceleration

ST Pharm Co., Ltd. shows 3 grants in 2022–2024 against only 9 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.
