Where Cardinal's grants concentrate

Cardinal IG Company is a focused PatentsView assignee: 32 CPC subclasses with 74.5% of grants classified under E06B (Fixed OR Movable Closures FOR Openings IN Buildings, Vehicles, Fences OR Like Enclosures IN General, e.g. Doors, Windows, Blinds, Gates). Peak complete grant year is 2021 (8 grants) versus a trough of 2 in 2016. By volume, Cardinal sits between China Tobacco Hunan Industrial Co., Ltd. and Cold Spring Harbor Laboratory.

Cardinal's three-year grant acceleration

Cardinal IG Company shows 18 grants in 2022–2024 against only 17 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.
