What this shows Purelifi's Innovation Score is 53.7/100 (top 9% 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 Purelifi?

Each dot is one of Purelifi’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). Purelifi’s own 27.4 claims/patent is ABOVE the 13.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Purelifi's grants concentrate

Purelifi Limited is a focused PatentsView assignee: 17 CPC subclasses with 100% of grants classified under H04B (Transmission). Peak complete grant year is 2022 (8 grants) versus a trough of 3 in 2019. By volume, Purelifi sits between OrthoPediatrics Corp. and People Center, Inc..

Purelifi's three-year grant acceleration

Purelifi Limited shows 18 grants in 2022–2024 against only 10 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.
