Tether, the leading stablecoin issuer, has intensified its expansion into South Korea by filing seven new trademark applications. These filings cover the "tether" company name, its logo, and the gold-backed stablecoin Tether Gold (XAUT). This move marks a shift from previous filings that focused primarily on stablecoin product names, suggesting Tether's intent to establish a more significant presence in the South Korean market.
