What this shows Haesung's Innovation Score is 39.6/100 (top 38% 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 Haesung?

Each dot is one of Haesung’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). Haesung’s own 12.2 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Haesung's grants concentrate

Haesung DS Co., Ltd is a focused PatentsView assignee: 24 CPC subclasses with 59.5% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2020 (9 grants) versus a trough of 1 in 2017. By volume, Haesung sits between G & W Electric Company and Hitachi Automotive Systems Steering, Ltd..

Haesung's three-year grant acceleration

Haesung DS Co., Ltd shows 6 grants in 2022–2024 against only 17 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.
