Company patents

Roland DG Corporation

Roland DG Corporation's patent strategy is heavily concentrated in "Printers & Typewriters," which accounts for 85.9% of its portfolio, experiencing a significant surge in 2025 with a 141.7% YoY growth, despite a sharp decline so far in 2026. Surprisingly, the company has almost entirely ceased patenting in "Medical Diagnostics & Surgery" and "Healthcare Informatics," both declining by 100.0% YoY in 2025 and showing no activity so far in 2026, indicating a clear shift away from these medical device sectors.
