What this shows Huizhou's Innovation Score is 42.6/100 (top 30% 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 6.7 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Huizhou's grants concentrate

Huizhou Roypow Technology Co., Ltd is a focused PatentsView assignee: 8 CPC subclasses with 18.2% of grants classified under B60H (Arrangements OF Heating, Cooling, Ventilating OR Other Air-treating Devices Specially Adapted FOR Passenger OR Goods Spaces OF Vehicles). By volume, Huizhou sits between HP3 Real GmbH and Hydropool Inc..

Huizhou's three-year grant acceleration

Huizhou Roypow Technology Co., Ltd shows 5 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.
