Does more volume mean deeper claims for Sichuan?

Each dot is one of Sichuan’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). Sichuan’s own 6.2 claims/patent is at or below the 9.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sichuan's grants concentrate

Sichuan Jamie Charming Technology Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 66.7% of grants classified under F21Y (Indexing Scheme Associated With Subclasses F21k, F21l, F21s and F21v, Relating TO THE Form OR THE Kind OF THE Light Sources OR OF THE Colour OF THE Light Emitted). By volume, Sichuan sits between Shuangqing Home Furnishings Co., Ltd and Siebel Systems, Inc..

Sichuan's three-year grant acceleration

Sichuan Jamie Charming Technology Co., Ltd. shows 4 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.
