What this shows Huizhou's Innovation Score is 50.7/100 (top 13% 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 7.0 claims/patent is at or below the 11.4 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 University is a focused PatentsView assignee: 36 CPC subclasses with 22.7% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2024 (8 grants) versus a trough of 1 in 2015. By volume, Huizhou sits between Hioki Denki Kabushiki Kaisha and Harry's, Inc..

Huizhou's three-year grant acceleration

Huizhou University shows 13 grants in 2022–2024 against only 6 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.
