Where Alcoa's grants concentrate

Alcoa USA Corp. is a focused PatentsView assignee: 19 CPC subclasses with 38.2% of grants classified under C25C (Processes FOR THE Electrolytic Production, Recovery OR Refining OF METALS; Apparatus Therefor). Peak complete grant year is 2017 (8 grants) versus a trough of 1 in 2016. By volume, Alcoa sits between fischerwerke GmbH & Co. KG and AMO WaveFront Sciences, LLC.

Alcoa's three-year grant acceleration

Alcoa USA Corp. shows 5 grants in 2022–2024 against only 12 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.
