Where R's grants concentrate

R & D Tool & Engineering Co. is a focused PatentsView assignee: 6 CPC subclasses with 90% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2017. By volume, R sits between Queen Mary & Westfield College, University of London and R.W. Beckett Corporation.

R's three-year grant acceleration

R & D Tool & Engineering Co. shows 2 grants in 2022–2024 against only 3 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.
