Where CDF's grants concentrate

CDF Corporation is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under B65D (CONTAINERS FOR STORAGE OR TRANSPORT OF ARTICLES OR MATERIALS, e.g. BAGS, BARRELS, BOTTLES, BOXES, CANS, CARTONS, CRATES, DRUMS, JARS, TANKS, HOPPERS, FORWARDING CONTAINERS; ACCESSORIES, CLOSURES, OR F). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2020. By volume, CDF sits between Cathay R&D Center Co., Ltd and Cellspect Co., Ltd..

CDF's three-year grant acceleration

CDF Corporation shows 2 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.
