4,926
observed patent filings on healthcare digital twins in 2024, up from 30 in 2016; the 2025 count (4,087) is incomplete
What the chart shows
Patent filings on digital twins in healthcare (patent class G16H) rose from 30 in 2016 to 4,926 in 2024, more than doubling between 2021 (1,159) and 2022 (2,395).
The 2025 figure, 4,087, looks lower, but the AI Index notes that not all patents filed in 2025 had been published or become public when the data was collected, so it will rise. The AI Index text gives 4,926 as the 2025 figure; in the data it is 2024’s, which we use.
