Where Windtree's grants concentrate

Windtree Therapeutics, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 66.7% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Windtree sits between Wildlife Research Center, Inc. and Wohner GmbH & Co. KG Elektrotechnische Systeme.

Windtree's three-year grant acceleration

Windtree Therapeutics, Inc. shows 1 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.
