Does more volume mean deeper claims for Zhejiang?

Each dot is one of Zhejiang’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). Zhejiang’s own 1.4 claims/patent is at or below the 13.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zhejiang's grants concentrate

Zhejiang Twinsel Electronic Technology Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 11.1% of grants classified under F21S (Non-portable Lighting DEVICES; Systems THEREOF; Vehicle Lighting Devices Specially Adapted FOR Vehicle Exteriors). Peak complete grant year is 2022 (6 grants) versus a trough of 1 in 2020. By volume, Zhejiang sits between Yiwu Ligao Technology Co., Ltd. and Zhejiang University City College.

Zhejiang's three-year grant acceleration

Zhejiang Twinsel Electronic Technology Co., Ltd. shows 11 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.
