Where C&u's grants concentrate

C&U Company Limited. is a focused PatentsView assignee: 3 CPC subclasses with 83.3% of grants classified under F16C (SHAFTS; Flexible SHAFTS; Elements OR Crankshaft MECHANISMS; Rotary Bodies Other Than Gearing ELEMENTS; Bearings). By volume, C&u sits between C & J Clark International Limited and C.R.D. Centro Ricerche Ducati Trento S.r.l..

C&u's three-year grant acceleration

C&U Company Limited. shows 6 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.
