Tether files eight trademark applications in South Korea, covering logo, USDT, and gold-backed XAUT

Tether, the world’s largest stablecoin issuer, has taken a significant step toward expanding its legal and commercial footprint in South Korea. According to a report by Etoday citing data from the Korea Intellectual Property Rights Information Service (KIPRIS), Tether filed a total of eight trademark applications in the country this month. The filings include the company’s logo, its dollar-pegged stablecoin USDT, and its gold-backed digital asset Tether Gold (XAUT).

Details of the trademark filings

The trademark applications were submitted in early May 2025 and cover a broad range of services. The XAUT application, in particular, is notably comprehensive. It extends to digital wallet services, virtual asset trading, exchange platforms, lending services, currency exchange, and the issuance and redemption of digital tokens. This suggests Tether is not merely protecting its brand but laying the groundwork for offering a wider suite of financial services in the South Korean market.

South Korea has one of the most active cryptocurrency trading markets in the world, but it also maintains a stringent regulatory environment. The country’s Virtual Asset User Protection Act, which came into effect in July 2024, requires exchanges to register with authorities and comply with strict custody and transparency rules. Tether’s trademark push signals a long-term commitment to operating within this regulated landscape.

Why this matters for the crypto industry

Stablecoins have become a critical infrastructure for global crypto trading, and South Korea is no exception. Local exchanges like Upbit and Bithumb handle billions of dollars in daily volume, much of it paired with USDT. By securing trademark rights, Tether strengthens its legal standing to enforce its brand, prevent counterfeit tokens, and potentially introduce new products tailored to the Korean market.

The inclusion of XAUT is particularly noteworthy. Gold-pegged tokens have seen growing interest as an alternative store of value, especially in markets where investors seek stability outside of fiat currencies. Tether’s move to trademark XAUT in South Korea could indicate plans to promote the token more actively among Korean institutional and retail investors.

Regulatory and competitive implications

Tether’s trademark filings come at a time when South Korean regulators are tightening oversight of stablecoins. The Financial Services Commission has signaled that it may require stablecoin issuers to hold reserves in local banks and undergo regular audits. Tether, which has faced scrutiny in the past over the composition of its reserves, has been working to improve transparency. In April 2025, the company published its latest assurance report showing reserves exceeding liabilities.

Competitors like Circle’s USDC and local stablecoin projects are also vying for market share in South Korea. By securing trademark rights early, Tether is positioning itself to defend its dominant position and potentially launch region-specific products.

Conclusion

Tether’s eight trademark applications in South Korea represent a strategic move to solidify its legal and commercial presence in one of the world’s most important crypto markets. The broad scope of the filings, especially for XAUT, suggests the company is preparing for a deeper, more regulated engagement with Korean users. As the regulatory landscape evolves, Tether’s proactive trademark strategy could give it a competitive edge in maintaining its market leadership.
