What this shows Hydac's Innovation Score is 41.7/100 (top 32% 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 17.2 claims/patent is ABOVE the 11.8 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 Fluidtechnik GMBH is a focused PatentsView assignee: 19 CPC subclasses with 63.6% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2017 (9 grants) versus a trough of 2 in 2024. By volume, Hydac sits between Gradiant Corporation and Inglass S.P.A.

Hydac's three-year grant acceleration

Hydac Fluidtechnik GMBH shows 6 grants in 2022–2024 against only 14 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.
