What this shows Shenzhen's Innovation Score is 43.8/100 (top 27% 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 Shenzhen?

Each dot is one of Shenzhen’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). Shenzhen’s own 3.9 claims/patent is ABOVE the 2.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shenzhen's grants concentrate

Shenzhen Qianyan Technology Ltd is a focused PatentsView assignee: 9 CPC subclasses with 18.2% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2024 (10 grants) versus a trough of 1 in 2023. By volume, Shenzhen sits between Sharrow Engineering LLC and Shoulder Innovations, Inc..

Shenzhen's three-year grant acceleration

Shenzhen Qianyan Technology Ltd shows 11 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.
