What this shows Aecc's Innovation Score is 44.3/100 (top 26% 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 Aecc?

Each dot is one of Aecc’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). Aecc’s own 10.6 claims/patent is at or below the 19.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Aecc's grants concentrate

Aecc Shanghai Commercial Aircraft Engine Manufacturing Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 80% of grants classified under F01D (Non-positive Displacement Machines OR Engines, e.g. Steam Turbines). By volume, Aecc sits between Advanced Systems AND Technologies, Inc. and AEM Holdings Ltd..

Aecc's three-year grant acceleration

Aecc Shanghai Commercial Aircraft Engine Manufacturing Co., Ltd. shows 4 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.
