What this shows Purigen's Innovation Score is 36.4/100 (top 46% 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 Purigen?

Each dot is one of Purigen’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). Purigen’s own 23.8 claims/patent is ABOVE the 15.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Purigen's grants concentrate

Purigen Biosystems, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under B01L (Chemical OR Physical Laboratory Apparatus FOR General USE). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2019. By volume, Purigen sits between Prothera Biologics, Inc. and Quantumctek Co.. Ltd..

Purigen's three-year grant acceleration

Purigen Biosystems, Inc. shows 3 grants in 2022–2024 against only 3 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.
