Does more volume mean deeper claims for Purple?

Each dot is one of Purple’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). Purple’s own 8.8 claims/patent is at or below the 19.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Purple's grants concentrate

Purple Mountain Observatory, Chinese Academy of Sciences is a focused PatentsView assignee: 13 CPC subclasses with 33.3% of grants classified under Y02A (Technologies FOR Adaptation TO Climate Change). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2021. By volume, Purple sits between PsiKick, Inc. and Q2 Artifical Lift Services ULC.

Purple's three-year grant acceleration

Purple Mountain Observatory, Chinese Academy of Sciences shows 4 grants in 2022–2024 against only 1 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.
