What this shows Hyosung's Innovation Score is 41.4/100 (top 33% 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 Hyosung?

Each dot is one of Hyosung’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). Hyosung’s own 8.4 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hyosung's grants concentrate

Hyosung Corporation is a focused PatentsView assignee: 38 CPC subclasses with 32% 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 2017 (8 grants) versus a trough of 1 in 2024. By volume, Hyosung sits between Hideit Mounts Inc and Hensley Industries, Inc..

Hyosung's three-year grant acceleration

Hyosung Corporation shows 1 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.
