Where Pandrol's grants concentrate

Pandrol Limited is a focused PatentsView assignee: 6 CPC subclasses with 95% of grants classified under E01B (Permanent WAY; Permanent-way TOOLS; Machines FOR Making Railways OF ALL Kinds). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2015. By volume, Pandrol sits between Pocared Diagnostics Ltd. and Peak Completion Technologies, Inc..

Pandrol's three-year grant acceleration

Pandrol Limited shows 7 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.
