Does more volume mean deeper claims for Lutian?

Each dot is one of Lutian’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). Lutian’s own 2.4 claims/patent is at or below the 10.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Lutian's grants concentrate

Lutian Machinery Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 20% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2023 (3 grants) versus a trough of 2 in 2024. By volume, Lutian sits between Luoxin Pharmaceutical (SHANGHAI) Co., Ltd. and Luxvisions Innovation Limited.

Lutian's three-year grant acceleration

Lutian Machinery Co., Ltd. shows 5 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.
