What this shows Hengst's Innovation Score is 40.2/100 (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 Hengst?

Each dot is one of Hengst’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). Hengst’s own 18.4 claims/patent is ABOVE the 11.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hengst's grants concentrate

Hengst SE is a focused PatentsView assignee: 10 CPC subclasses with 63.2% of grants classified under B01D (Separation). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2020. By volume, Hengst sits between Hauni Maschinenbau GMBH and Hitachi-omron Terminal Solutions, Corp..

Hengst's three-year grant acceleration

Hengst SE shows 8 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.
