What this shows Taizhou's Innovation Score is 23.0/100 (11th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Taizhou?

Each dot is one of Taizhou’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). Taizhou’s own 4.2 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Taizhou's grants concentrate

Taizhou JiaoGuang Lighting Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 16.7% of grants classified under F21S (Non-portable Lighting DEVICES; Systems THEREOF; Vehicle Lighting Devices Specially Adapted FOR Vehicle Exteriors). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2022. By volume, Taizhou sits between Taisei Lamick Co., Ltd. and Tangible Science, Inc..

Taizhou's three-year grant acceleration

Taizhou JiaoGuang Lighting Co., Ltd. shows 2 grants in 2022–2024 against only 2 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.
