What this shows Guangzhou's Innovation Score is 29.7/100 (32nd 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 Guangzhou?

Each dot is one of Guangzhou’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). Guangzhou’s own 6.6 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Guangzhou's grants concentrate

Guangzhou T.K Medical Instrument Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 28.6% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2017 (9 grants) versus a trough of 1 in 2016. By volume, Guangzhou sits between GM Global Technologies Operations LLC and Gallagher Group Limited.

Guangzhou's three-year grant acceleration

Guangzhou T.K Medical Instrument Co., Ltd. shows 2 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.
