Does more volume mean deeper claims for Yulan?

Each dot is one of Yulan’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). Yulan’s own 5.1 claims/patent is at or below the 16.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yulan's grants concentrate

Yulan Green Technology Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 42.9% of grants classified under D21J (FIBREBOARD; Manufacture OF Articles From Cellulosic Fibrous Suspensions OR From Papier-mache). By volume, Yulan sits between Yong San Co., Ltd. and Zealio Electronics Co., Ltd..

Yulan's three-year grant acceleration

Yulan Green Technology Co., Ltd. shows 2 grants in 2022–2024 against only 1 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.
