What this shows Zhongchao's Innovation Score is 33.7/100 (45th 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 Zhongchao?

Each dot is one of Zhongchao’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). Zhongchao’s own 17.9 claims/patent is ABOVE the 5.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zhongchao's grants concentrate

Zhongchao Special Security Technology Co., Ltd is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under B42D (BOOKS; Book COVERS; Loose LEAVES; Printed Matter Characterised BY Identification OR Security FEATURES; Printed Matter OF Special Format OR Style NOT Otherwise Provided FOR; Devices FOR USE Therewith A). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2018. By volume, Zhongchao sits between Zhejiang Okai Vehicle Co., Ltd. and ams Sensors Germany GmbH.

Zhongchao's three-year grant acceleration

Zhongchao Special Security Technology Co., Ltd shows 1 grants in 2022–2024 against only 3 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.
