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 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.
