Company patents
LINE Plus Corporation
LINE Plus Corporation's patent strategy reveals a surprising shift away from its core Messaging & Email, which constitutes 40.4% of its portfolio but saw a significant decline in filings in 2024 (-47.8% YoY) and 2026 so far (-62.5% YoY). While many categories experienced sharp declines in 2024, the company shows an emerging focus in Databases & Information Retrieval, which grew by 200% in 2025 and maintained its filing rate so far in 2026.
