Where C&m's grants concentrate

C&M Oilfield Rentals, L.L.C. is a focused PatentsView assignee: 5 CPC subclasses with 85.7% of grants classified under F21W (Indexing Scheme Associated With Subclasses F21k, F21l, F21s and F21v, Relating TO Uses OR Applications OF Lighting Devices OR Systems). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2022. By volume, C&m sits between Buzzbox Beverages, Inc. and C.I. Takiron Corporation.

C&m's three-year grant acceleration

C&M Oilfield Rentals, L.L.C. shows 2 grants in 2022–2024 against only 5 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.
