This study explored how patent analysis can support innovation and horizon scanning in health care. Through a rapid scoping review of 124 studies published since 2020, it found that patents serve as valuable early indicators of technological trends, particularly in areas like cancer and respiratory conditions. Most studies relied on patent databases, with many using automated and visualization tools to map trends and strategies. However, inconsistent methods, especially around deduplication, risk inflating results. Overall, patents provide important insights for policy, research, and strategy development, but greater methodological transparency is needed.
