What this shows Wärtsilä's Innovation Score is 49.0/100 (top 15% 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 Wärtsilä?

Each dot is one of Wärtsilä’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). Wärtsilä’s own 14.5 claims/patent is ABOVE the 12.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Wärtsilä's grants concentrate

WÄRTSILÄ Finland OY is a focused PatentsView assignee: 41 CPC subclasses with 52.4% of grants classified under Y02T (Climate Change Mitigation Technologies Related TO Transportation). Peak complete grant year is 2020 (7 grants) versus a trough of 1 in 2023. By volume, Wärtsilä sits between Veris Industries, LLC and Zhuhai Kelitong Electronic Co., Ltd..

Wärtsilä's three-year grant acceleration

WÄRTSILÄ Finland OY shows 12 grants in 2022–2024 against only 17 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.
