Where C.d.l.'s grants concentrate

C.d.l. Electric Company, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under B61L (GUIDING RAILWAY TRAFFIC; ENSURING THE SAFETY OF RAILWAY TRAFFIC). Peak complete grant year is 2023 (4 grants) versus a trough of 2 in 2024. By volume, C.d.l. sits between Buhler Ag and Canadian BANK NOTE Company, Limited.

C.d.l.'s three-year grant acceleration

C.d.l. Electric Company, Inc. shows 9 grants in 2022–2024 against only 0 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.
