What this shows Hydac's Innovation Score is 40.3/100 (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 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 13.3 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 Hydac's grants concentrate

Hydac Cooling GMBH is a focused PatentsView assignee: 12 CPC subclasses with 66.7% of grants classified under F28F (Details OF Heat-exchange AND Heat-transfer Apparatus, OF General Application). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2015. By volume, Hydac sits between Huttenes-albertus Chemische Werke Gesellschaft mit beschränkter haftung and Hypercel Corporation.

Hydac's three-year grant acceleration

Hydac Cooling GMBH shows 2 grants in 2022–2024 against only 1 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.
