Portfolio overview

SEO WON Korea Co., Ltd. has been granted 10 US utility patents between 2020 and 2025, placing SEO WON Korea Co., Ltd. at rank #27,309 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.0 claims per patent with primary concentration in 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). As a Foreign Corporation, SEO WON Korea Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, SEO sits between Semrock, Inc. (10 patents, rank #27,305) and SFC Global Supply Chain, Inc. (10 patents, rank #27,313) - the closest US assignees by grant volume. The composite Innovation Score of 28.8/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Historical data spans 2020 through 2025, with 10 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. SEO WON Korea Co., Ltd.'s 4.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SEO WON Korea Co., Ltd. against peers pursuing similar technology classes.
