Does more volume mean deeper claims for Haohong?

Each dot is one of Haohong’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). Haohong’s own 1.8 claims/patent is at or below the 8.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Haohong's grants concentrate

Haohong Electric Technology (Hubei) Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 5.3% of grants classified under F24C (Domestic Stoves OR Ranges ; Details OF Domestic Stoves OR Ranges, OF General Application). Peak complete grant year is 2024 (7 grants) versus a trough of 1 in 2023. By volume, Haohong sits between Hytorc Division Unex Corporation and Honeywell ASCa.

Haohong's three-year grant acceleration

Haohong Electric Technology (Hubei) Co., Ltd. shows 8 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.
