What this shows Guangzhou's Innovation Score is 28.8/100 (29th 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 10.2 claims/patent is ABOVE the 8.8 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 Tech-long Packaging Machinery Co., Ltd is a focused PatentsView assignee: 7 CPC subclasses with 83.3% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2016. By volume, Guangzhou sits between Guangdong Zhaoqing L&V Co. Ltd. and GX Technology Canada Ltd..

Guangzhou's three-year grant acceleration

Guangzhou Tech-long Packaging Machinery Co., Ltd shows 2 grants in 2022–2024 against only 2 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.
