What this shows Walvoil's Innovation Score is 26.9/100 (22nd percentile 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 Walvoil?

Each dot is one of Walvoil’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). Walvoil’s own 11.2 claims/patent is at or below the 14.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Walvoil's grants concentrate

Walvoil S.P.A. is a focused PatentsView assignee: 5 CPC subclasses with 80% 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 2020 (2 grants) versus a trough of 1 in 2018. By volume, Walvoil sits between Vricon Systems Aktiebolag and Weber Orthopedic, Inc..

Walvoil's three-year grant acceleration

Walvoil S.P.A. shows 3 grants in 2022–2024 against only 5 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.
