Where Martinrea's grants concentrate

Martinrea International US Inc. is a focused PatentsView assignee: 12 CPC subclasses with 55.6% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2024 (3 grants) versus a trough of 2 in 2020. By volume, Martinrea sits between Mapped Inc. and Matergenics, Inc..

Martinrea's three-year grant acceleration

Martinrea International US Inc. shows 5 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.
