What this shows Shenzhen's Innovation Score is 24.7/100 (15th 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 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 9.7 claims/patent is ABOVE the 2.3 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 Hongfei Precision Technology Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 42.9% of grants classified under F16M (Frames, Casings OR Beds OF Engines, Machines OR Apparatus, NOT Specific TO Engines, Machines OR Apparatus Provided FOR ELSEWHERE; STANDS; Supports). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2021. By volume, Shenzhen sits between Shannon Specialty Floors, Inc. and Shenzhen Baishanchuan Technology Co., Ltd.

Shenzhen's three-year grant acceleration

ShenZhen Hongfei Precision Technology Co., Ltd. shows 1 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.
