Where Quantum's grants concentrate

Quantum Design International, Inc. is a focused PatentsView assignee: 15 CPC subclasses with 50% of grants classified under F25B (Refrigeration Machines, Plants OR SYSTEMS; Combined Heating AND Refrigeration SYSTEMS; Heat Pump Systems). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2018. By volume, Quantum sits between Qualipac and Qu Biologics Inc..

Quantum's three-year grant acceleration

Quantum Design International, Inc. shows 1 grants in 2022–2024 against only 2 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.
