Where Qu's grants concentrate

Qu Biologics Inc. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2017. By volume, Qu sits between Quantum Design International, Inc. and Quest Products, LLC.

Qu's three-year grant acceleration

Qu Biologics Inc. shows 2 grants in 2022–2024 against only 1 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.
