It is moderately concentrated but not dominated by a single owner. The five leading assignees combined hold 18.1% of all 2,365 records in scope, and the ten leading assignees hold 25.2%. That leaves the large majority of filings spread across a long tail of smaller and single-filing entrants, which means a new entrant has real room to build a defensible position rather than facing a field already locked up by a handful of incumbents.

Healthcare informatics, classified under IPC subclass G16H, appears on 60.0% of the 2,365 records in scope and is by far the largest single category. General digital data processing (G06F) and business/administrative data processing (G06Q) follow at 32.5% and 27.0% respectively, reflecting how much of this field is built on data-handling and workflow logic rather than device hardware. Diagnosis-and-surgery claims (A61B) and AI-model computing (G06N) each sit near or under 20%, marking narrower but active secondary territory.

Filings grew from 164 records in 2021 to 197 in 2024, a 20% rise over that three-year window, which is the most reliable recent trend because it predates the publication lag that affects 2025 and 2026 data. Later years in the dataset show lower counts, but that reflects the roughly 18-month gap between filing and publication rather than an actual slowdown. Any read of the most recent one to two years should be treated as provisional until later publications catch up.

The United States receives the largest share of filings in this dataset, with India and the WIPO PCT route as the next largest receiving offices, followed by Europe, Canada and Australia at smaller volumes. That pattern suggests most applicants build a US-centred filing strategy first and pursue international protection selectively rather than filing broadly across all major jurisdictions from the outset.

The clearest openings sit adjacent to the dense G16H and G06Q claim territory rather than inside it: areas like fleet-level analytics across physical care stations, command-center handling of emergency records, and remote intake-to-consultation orchestration carry comparatively few filings relative to core informatics and workflow claims. Image and video recognition applied to care workflow (G06V) is also thin relative to the rest of the field. These are reasonable starting points for a design-around or first-filing strategy, but each should be checked against the specific claim language of nearby records before drafting.
