What this shows Hydac's Innovation Score is 42.1/100 (top 31% 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 Hydac?

Each dot is one of Hydac’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). Hydac’s own 15.5 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hydac's grants concentrate

Hydac Process Technology GMBH is a focused PatentsView assignee: 11 CPC subclasses with 96.3% of grants classified under B01D (Separation). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2024. By volume, Hydac sits between Gurit (UK) Ltd. and Honor Metro Limited.

Hydac's three-year grant acceleration

Hydac Process Technology GMBH 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.
