What this shows Evac's Innovation Score is 38.3/100 (top 41% 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 Evac?

Each dot is one of Evac’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). Evac’s own 11.0 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Evac's grants concentrate

Evac OY is a focused PatentsView assignee: 10 CPC subclasses with 42.9% of grants classified under E03F (SEWERS; Cesspools). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2015. By volume, Evac sits between Etherwhere Corporation and Evoke Pharma, Inc..

Evac's three-year grant acceleration

Evac OY shows 4 grants in 2022–2024 against only 2 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.
