What this shows Perma's Innovation Score is 22.5/100 (10th percentile 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 Perma's grants concentrate

Perma Pure LLC is a focused PatentsView assignee: 3 CPC subclasses with 42.9% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2020. By volume, Perma sits between Percepto Robotics Ltd and PetroQuip Energy Services, LLC.

Perma's three-year grant acceleration

Perma Pure LLC shows 1 grants in 2022–2024 against only 6 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.
