What this shows Pura's Innovation Score is 18.9/100 (5th 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 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 2.5 claims/patent is at or below the 11.6 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 Stainless LLC is a focused PatentsView assignee: 2 CPC subclasses with 7.7% of grants classified under A61J (Containers Specially Adapted FOR Medical OR Pharmaceutical PURPOSES; Devices OR Methods Specially Adapted FOR Bringing Pharmaceutical Products Into Particular Physical OR Administering FORMS; Devices ). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2015. By volume, Pura sits between Prinx Chengshan (QINGDAO) Industrial Research AND Design Co., Ltd. and Panasia Co., Ltd..

Pura's three-year grant acceleration

Pura Stainless LLC shows 1 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.
