Where Certainteed's grants concentrate

Certainteed Canada, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under E04B (GENERAL BUILDING CONSTRUCTIONS; WALLS, e.g. PARTITIONS; ROOFS; FLOORS; CEILINGS; INSULATION OR OTHER PROTECTION OF BUILDINGS). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2017. By volume, Certainteed sits between Cellepathy Inc. and Chemometec A/s.

Certainteed's three-year grant acceleration

Certainteed Canada, Inc. shows 3 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.
