Korean Telecoms Race to Secure Overseas Patents in 6G, Quantum

The push for overseas patents by South Korean telcos directly targets future licensing revenue and influence over global standards. KT's 20.9% increase in overseas patents over three years and SK Telecom's 14.2% rise reflect a clear shift from domestic focus. This positions them to benefit if their AI-based communication or quantum key distribution technologies become 6G international standards.

This strategy creates a distinct advantage for Korean carriers in the regional race for 6G leadership. By locking in rights early, they can dictate terms for other Asian players. The emphasis on AI-RAN and quantum key distribution patents, particularly in the US and Europe, shows a deliberate effort to secure market share beyond Korea. This puts pressure on competitors in China and Japan to accelerate their own international patent filings.

The thing to watch is the adoption rate of these specific patented technologies into international standards. If KT's conditional handover technology or SK Telecom's AI workload distribution system gain traction, their patent portfolios become significant assets. Failure to influence standards will relegate these filings to defensive positions, limiting their revenue potential.
