What this shows Asian's Innovation Score is 35.0/100 (top 50% 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 Asian?

Each dot is one of Asian’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). Asian’s own 7.9 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Asian's grants concentrate

Asian Power Devices Inc. is a focused PatentsView assignee: 14 CPC subclasses with 89.3% of grants classified under H02M (Apparatus FOR Conversion Between AC AND AC, Between AC AND DC, OR Between DC AND DC, AND FOR USE With Mains OR Similar Power Supply SYSTEMS; Conversion OF DC OR AC Input Power Into Surge Output POWER;). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2015. By volume, Asian sits between Anavex Life Sciences Corp. and Action Target Inc..

Asian's three-year grant acceleration

Asian Power Devices Inc. shows 9 grants in 2022–2024 against only 11 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.
