Does more volume mean deeper claims for Heifeng?
Each dot is one of Heifeng’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). Heifeng’s own 2.1 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Heifeng's grants concentrate
Heifeng Zhizao (SHENZHEN) Technology Co., Ltd is a focused PatentsView assignee: 4 CPC subclasses with 7.1% of grants classified under A45D (Hairdressing OR Shaving Equipment ; Equipment FOR Cosmetics OR Cosmetic Treatments, e.g. FOR Manicuring OR Pedicuring). Peak complete grant year is 2022 (14 grants) versus a trough of 2 in 2024. By volume, Heifeng sits between H & M Innovations, LLC and Honey BEE Manufacturing Ltd..
Heifeng's three-year grant acceleration
Heifeng Zhizao (SHENZHEN) Technology Co., Ltd shows 22 grants in 2022–2024 against only 4 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.
