Company patents
KT CORPORATION
KT CORPORATION's patent strategy is heavily concentrated in communications, with nearly half of its portfolio (47.1%) in Pictorial / Video Communications and another 44.5% in Wireless Networks. While Wireless Networks showed robust growth of +53.5% in 2025, it's surprising to see a significant decline in patenting activity across most categories so far in 2026, including a -61.0% drop in Pictorial / Video Communications and a -60.6% drop in Wireless Networks, suggesting a potential shift in focus or a temporary slowdown in filings.
