Does more volume mean deeper claims for Linhai?

Each dot is one of Linhai’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). Linhai’s own 2.6 claims/patent is at or below the 10.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Linhai's grants concentrate

Linhai Guokang Leisure Products Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 25% of grants classified under A45B (Walking Sticks ; UMBRELLAS; Ladies' OR Like Fans). Peak complete grant year is 2022 (4 grants) versus a trough of 2 in 2023. By volume, Linhai sits between Lifeline Systems Company and LiveClips LLC.

Linhai's three-year grant acceleration

Linhai Guokang Leisure Products Co., Ltd. shows 6 grants in 2022–2024 against only 3 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.
