What this shows Wartsilä's Innovation Score is 42.5/100 (top 30% 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 Wartsilä?

Each dot is one of Wartsilä’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). Wartsilä’s own 10.1 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Wartsilä's grants concentrate

WARTSILÄ Finland OY is a focused PatentsView assignee: 36 CPC subclasses with 27% of grants classified under B63H (Marine Propulsion OR Steering). Peak complete grant year is 2017 (10 grants) versus a trough of 1 in 2022. By volume, Wartsilä sits between Verifood, Ltd. and WirePath Home Systems, LLC.

Wartsilä's three-year grant acceleration

WARTSILÄ Finland OY shows 2 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.
