What this shows Guangzhou's Innovation Score is 27.0/100 (22nd 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 15.4 claims/patent is ABOVE the 2.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Guangzhou's grants concentrate

Guangzhou Pulisi Technology Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 60% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2023. By volume, Guangzhou sits between Guangzhou Innocare Pharma Tech Co., Ltd. and Guided Delivery Systems, Inc..

Guangzhou's three-year grant acceleration

Guangzhou Pulisi 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.
