What this shows Purus's Innovation Score is 32.5/100 (41st 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 Purus?

Each dot is one of Purus’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). Purus’s own 17.3 claims/patent is ABOVE the 16.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Purus Power Corporation is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F03D (Wind Motors). By volume, Purus sits between Pulmokine, Inc. and Pyxalis.

Purus's three-year grant acceleration

Purus Power Corporation shows 1 grants in 2022–2024 against only 0 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.
