What this shows Wista's Innovation Score is 40.4/100 (top 36% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Where Wista's grants concentrate

WisTa Laboratories Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 86.1% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2022. By volume, Wista sits between Voicebox Technologies Corporation and Adocia.

Wista's three-year grant acceleration

WisTa Laboratories Ltd. shows 6 grants in 2022–2024 against only 11 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.
