Where Mack-ray's grants concentrate

Mack-Ray Inc. is a focused PatentsView assignee: 1 CPC subclasses with 75% of grants classified under B26B (Hand-held Cutting Tools NOT Otherwise Provided FOR). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2018. By volume, Mack-ray sits between Mylaps B.V. and Magna Car Top Systems GmbH.

Mack-ray's three-year grant acceleration

Mack-Ray Inc. shows 1 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.
