What this shows Huizhou's Innovation Score is 42.0/100 (top 32% 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 Huizhou?

Each dot is one of Huizhou’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). Huizhou’s own 6.8 claims/patent is ABOVE the 6.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Huizhou's grants concentrate

Huizhou Hanxu Hardware & Plastic Technology Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 83.3% of grants classified under F28F (Details OF Heat-exchange AND Heat-transfer Apparatus, OF General Application). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2022. By volume, Huizhou sits between HUA KU (SHUNDE) Tech Electric Co., Ltd. and Hunan San'an Semiconductor Co., Ltd..

Huizhou's three-year grant acceleration

Huizhou Hanxu Hardware & Plastic Technology Co., Ltd. shows 6 grants in 2022–2024 against only 0 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.
