What this shows Wetend's Innovation Score is 40.9/100 (top 34% 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 Wetend?

Each dot is one of Wetend’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). Wetend’s own 12.6 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Wetend's grants concentrate

Wetend Technologies Oy is a focused PatentsView assignee: 11 CPC subclasses with 80% of grants classified under D21H (Pulp COMPOSITIONS; Preparation Thereof NOT Covered BY Subclasses D21c OR D21D; Impregnating OR Coating OF PAPER; Treatment OF Finished Paper NOT Covered BY Class B31 OR Subclass D21G; Paper NOT Otherw). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2022. By volume, Wetend sits between WellWorx Energy Solutions LLC and Witzenmann GmbH.

Wetend's three-year grant acceleration

Wetend Technologies Oy shows 2 grants in 2022–2024 against only 0 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.
