Where Acciona's grants concentrate

Acciona Energia S.a. is a focused PatentsView assignee: 21 CPC subclasses with 90% of grants classified under Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2016. By volume, Acciona sits between Abengoa Bioenergía Nuevas Technologías, S.a. and Acessa Health Inc..

Acciona's three-year grant acceleration

Acciona Energia S.a. shows 2 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.
