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 1.0 claims/patent is at or below the 14.4 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 du du Pet Products Co. Ltd is a focused PatentsView assignee: 0 CPC subclasses . By volume, Huizhou sits between Hoyos Labs IP Ltd. and Hurricane Safety Systems, LLC.
Huizhou's three-year grant acceleration
Huizhou du du Pet Products Co. Ltd shows 4 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.
