What this shows Seoyon's Innovation Score is 49.0/100 (top 15% 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 Seoyon?

Each dot is one of Seoyon’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). Seoyon’s own 10.0 claims/patent is at or below the 12.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Seoyon's grants concentrate

Seoyon E-hwa Co., Ltd. is a focused PatentsView assignee: 39 CPC subclasses with 48% of grants classified under B60R (Vehicles, Vehicle Fittings, OR Vehicle Parts, NOT Otherwise Provided FOR). Peak complete grant year is 2024 (13 grants) versus a trough of 2 in 2017. By volume, Seoyon sits between Peloton Technology, Inc. and ST. Jude Medical Coordination Center Bvba.

Seoyon's three-year grant acceleration

Seoyon E-hwa Co., Ltd. shows 21 grants in 2022–2024 against only 19 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.
