What this shows ST's Innovation Score is 35.9/100 (top 48% 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 17.6 claims/patent is ABOVE the 13.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where ST's grants concentrate

ST Engineering Aerospace Ltd is a focused PatentsView assignee: 9 CPC subclasses with 46.2% of grants classified under B64C (AEROPLANES; Helicopters). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2021. By volume, ST sits between Spinalcyte, LLC and Starkeys LLC.

ST's three-year grant acceleration

ST Engineering Aerospace Ltd shows 5 grants in 2022–2024 against only 6 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.
