Where Astex's grants concentrate

Astex Therapeutics Limited is a focused PatentsView assignee: 13 CPC subclasses with 95.7% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2016 (14 grants) versus a trough of 3 in 2021. By volume, Astex sits between Wickr Inc. and Bendix Spicer Foundation Brake LLC.

Astex's three-year grant acceleration

Astex Therapeutics Limited shows 11 grants in 2022–2024 against only 17 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.
