What this shows Guangzhou's Innovation Score is 22.2/100 (10th 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 2.8 claims/patent is ABOVE the 1.0 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 Homfel Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 16.7% 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 2024 (2 grants) versus a trough of 1 in 2019. By volume, Guangzhou sits between Guangdong SunRise Industrial Co., Ltd. and Guangzhou Mino Automotive Equipment Co., Ltd..

Guangzhou's three-year grant acceleration

Guangzhou Homfel 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.
