Where Calera's grants concentrate

Calera Corporation is a focused PatentsView assignee: 22 CPC subclasses with 69.7% of grants classified under C25B (Electrolytic OR Electrophoretic Processes FOR THE Production OF Compounds OR NON-METALS; Apparatus Therefor). Peak complete grant year is 2015 (10 grants) versus a trough of 1 in 2017. By volume, Calera sits between Center FOR Advanced Meta-materials and CoreLogic Solutions, LLC.

Calera's three-year grant acceleration

Calera Corporation shows 1 grants in 2022–2024 against only 14 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.
