Does more volume mean deeper claims for Purplevine?

Each dot is one of Purplevine’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). Purplevine’s own 47.0 claims/patent is ABOVE the 19.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Purplevine's grants concentrate

Purplevine Innovation Company Limited is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under H04W (Wireless Communication Networks). By volume, Purplevine sits between PulsePoint, Inc. and Qatar University Qstp-b.

Purplevine's three-year grant acceleration

Purplevine Innovation Company Limited shows 2 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.
