What this shows Pura's Innovation Score is 39.2/100 (top 39% 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 Pura?

Each dot is one of Pura’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). Pura’s own 7.4 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Pura's grants concentrate

Pura Scents, Inc. is a focused PatentsView assignee: 2 CPC subclasses with 37.5% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2017. By volume, Pura sits between Princeton Optronics, Inc. and Qualicaps Co., Ltd..

Pura's three-year grant acceleration

Pura Scents, Inc. shows 6 grants in 2022–2024 against only 2 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.
