What this shows Liaoning's Innovation Score is 36.1/100 (top 47% 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 Liaoning?

Each dot is one of Liaoning’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). Liaoning’s own 12.8 claims/patent is at or below the 12.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Liaoning's grants concentrate

Liaoning Upcera Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 60% of grants classified under F27D (Details OR Accessories OF Furnaces, Kilns, Ovens OR Retorts, IN SO FAR AS They ARE OF Kinds Occurring IN More Than ONE Kind OF Furnace). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2020. By volume, Liaoning sits between Levitate Technologies, Inc. and Liberty Global Europe Holding B.V..

Liaoning's three-year grant acceleration

Liaoning Upcera Co., Ltd. shows 3 grants in 2022–2024 against only 2 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.
