What this shows SEO's Innovation Score is 28.8/100 (28th 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 SEO?

Each dot is one of SEO’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). SEO’s own 4.0 claims/patent is at or below the 17.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where SEO's grants concentrate

SEO WON Korea Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 90% of grants classified under E05Y (Indexing Scheme Associated With Subclasses E05d AND E05f, Relating TO Construction Elements, Electric Control, Power Supply, Power Signal OR Transmission, User Interfaces, Mounting OR Coupling, Detail). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2020. By volume, SEO sits between Semrock, Inc. and SFC Global Supply Chain, Inc..

SEO's three-year grant acceleration

SEO WON Korea Co., Ltd. shows 4 grants in 2022–2024 against only 5 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.
