Where Largo's grants concentrate

Largo Clean Energy Corp. is a focused PatentsView assignee: 9 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 2023 (2 grants) versus a trough of 1 in 2021. By volume, Largo sits between Langeman Manufacturing Limited and Lateral Reality Kft..

Largo's three-year grant acceleration

Largo Clean Energy Corp. shows 4 grants in 2022–2024 against only 1 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.
