Where Cornerstone's grants concentrate

Cornerstone Intellectual Property, LLC is a focused PatentsView assignee: 14 CPC subclasses with 100% of grants classified under C22C (Alloys). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Cornerstone sits between Cordstrap B.V. and Corvus Energy Inc..

Cornerstone's three-year grant acceleration

Cornerstone Intellectual Property, LLC shows 1 grants in 2022–2024 against only 4 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.
