Does more volume mean deeper claims for Chameleon?

Each dot is one of Chameleon’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). Chameleon’s own 8.8 claims/patent is at or below the 10.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chameleon's grants concentrate

Chameleon Holding Ltd is a focused PatentsView assignee: 3 CPC subclasses with 55.6% of grants classified under B43L (Articles FOR Writing OR Drawing UPON; ; Writing OR Drawing AIDS;; Accessories FOR Writing OR Drawing). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Chameleon sits between Central Valley Seeds, Inc. and Changzhou Shine Science & Technology Co. Ltd..

Chameleon's three-year grant acceleration

Chameleon Holding Ltd shows 1 grants in 2022–2024 against only 4 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.
