No single assignee dominates this field. The leading filer holds only 2 of the 37 tracked records, and the top 5 assignees combined account for 24.3% of all filings in scope. With 71 assignees ranked overall and most holding just one or two records, ownership is spread thin rather than concentrated in a handful of large portfolios.

The overall record count is modest at 37 published records, but claim density inside the dominant IPC class is high: 83.8% of those records carry a G16H healthcare informatics classification. That signals occupied claim space around care-coordination workflow logic specifically, not that the broader interoperability technology as a whole is saturated or mature.

Of the 37 records tracked, 23 were filed through the Indian receiving office, compared with 7 through the United States, 4 through WIPO/PCT, 2 through Canada, and 1 through Taiwan. This receiving-office mix reflects where applicants in this dataset chose to file first; a team relying only on USPTO or PCT alerts would miss the majority of activity in this space.

Not yet, based on this dataset. G06N, the classification covering AI-based computing methods, appears on only 18.9% of the 37 records, well behind G16H healthcare informatics at 83.8%. Most claims currently frame the FHIR exchange problem as a data-workflow and interoperability challenge rather than as a machine-learning method applied to the exchanged clinical data.

Filings rose from 1 record in 2017 to a peak of 14 in 2025, with 10 more already published in 2026 even though that year is incomplete at the data cut-off. A precise growth rate cannot be stated here because fewer than four complete years remain once the roughly 18-month publication lag is factored in, and the 2026 figure will rise further as later filings publish.
