Does more volume mean deeper claims for Certainteed?

Each dot is one of Certainteed’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Certainteed’s own 16.7 claims/patent is ABOVE the 15.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
