What this shows Seohan's Innovation Score is 28.1/100 (26th percentile 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 Seohan?

Each dot is one of Seohan’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). Seohan’s own 5.8 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Seohan's grants concentrate

Seohan Industry Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under F16D (Couplings FOR Transmitting ROTATION; CLUTCHES; Brakes). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2017. By volume, Seohan sits between Sentec E&E Co., Ltd. and Sequoia Pharmaceuticals, Inc..

Seohan's three-year grant acceleration

Seohan Industry Co., Ltd. shows 3 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.
