What this shows Aster's Innovation Score is 42.3/100 (top 31% 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 Aster?

Each dot is one of Aster’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). Aster’s own 9.7 claims/patent is at or below the 11.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Aster's grants concentrate

Aster Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2024 (7 grants) versus a trough of 1 in 2019. By volume, Aster sits between Aspargo Laboratories, Inc. and Audiocodes Ltd..

Aster's three-year grant acceleration

Aster Co., Ltd. shows 8 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.
