Where Merck's grants concentrate

Merck Millipore Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 88.9% of grants classified under B01D (Separation). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2021. By volume, Merck sits between Meijer, Inc. and Metamagnetics, Inc..

Merck's three-year grant acceleration

Merck Millipore Ltd. shows 3 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.
