What this shows Luoyang's Innovation Score is 42.7/100 (top 30% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Luoyang?

Each dot is one of Luoyang’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). Luoyang’s own 12.9 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 Luoyang's grants concentrate

Luoyang Landglass Technology Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 59.1% of grants classified under E06B (Fixed OR Movable Closures FOR Openings IN Buildings, Vehicles, Fences OR Like Enclosures IN General, e.g. Doors, Windows, Blinds, Gates). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2016. By volume, Luoyang sits between Luxshare-ict Co., Ltd. and Matsumoto Yushi-seiyaku Co., Ltd..

Luoyang's three-year grant acceleration

Luoyang Landglass Technology Co., Ltd. shows 5 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.
