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.

Does more volume mean deeper claims for Perma?

Each dot is one of Perma’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Perma’s own 13.4 claims/patent is ABOVE the 8.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
