What this shows Hydac's Innovation Score is 36.0/100 (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 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 14.5 claims/patent is ABOVE the 10.5 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 Systems & Services GMBH is a focused PatentsView assignee: 15 CPC subclasses with 64.7% of grants classified under F15B (Systems Acting BY Means OF Fluids IN GENERAL; Fluid-pressure Actuators, e.g. SERVOMOTORS; Details OF Fluid-pressure Systems, NOT Otherwise Provided FOR). Peak complete grant year is 2021 (8 grants) versus a trough of 1 in 2023. By volume, Hydac sits between Hoppe Holding AG and Homag Holzbearbeitungssysteme GmbH.

Hydac's three-year grant acceleration

Hydac Systems & Services GMBH shows 6 grants in 2022–2024 against only 11 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.
