Where Cornerstone's grants concentrate

Cornerstone Research Group, Inc. is a focused PatentsView assignee: 47 CPC subclasses with 23.5% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2022 (5 grants) versus a trough of 2 in 2017. By volume, Cornerstone sits between ClearOne, Inc. and Dong Guan Song WEI Electric Technology Co., Ltd..

Cornerstone's three-year grant acceleration

Cornerstone Research Group, Inc. shows 14 grants in 2022–2024 against only 9 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.
