What this shows Acciona's Innovation Score is 42.9/100 (top 29% 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 Acciona?

Each dot is one of Acciona’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). Acciona’s own 17.1 claims/patent is at or below the 18.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Acciona's grants concentrate

Acciona Windpower, S.A. is a focused PatentsView assignee: 25 CPC subclasses with 100% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2018 (10 grants) versus a trough of 1 in 2021. By volume, Acciona sits between AIR Cruisers Company, LLC and Amcor Limited.

Acciona's three-year grant acceleration

Acciona Windpower, S.A. shows 3 grants in 2022–2024 against only 8 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.
