Does more volume mean deeper claims for Nantong?

Each dot is one of Nantong’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). Nantong’s own 6.9 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nantong's grants concentrate

Nantong YA TAI Candle Arts & Crafts Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 78.6% of grants classified under F21S (Non-portable Lighting DEVICES; Systems THEREOF; Vehicle Lighting Devices Specially Adapted FOR Vehicle Exteriors). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2015. By volume, Nantong sits between Nanogrid Limited and NEO Medical SA.

Nantong's three-year grant acceleration

Nantong YA TAI Candle Arts & Crafts Co., Ltd. shows 2 grants in 2022–2024 against only 6 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.
