Patent Strategy for Medical AI Web Services — Rights and Enforcement in the Age of Distributed Deployment

Part 4: When Your Customer Is Anyone — or an AI — Anywhere: API Access and the Vanishing 'Infringer' [Paid]

June 19, 2026 · Shishido & Associates

The users of a medical AI web service are no longer confined to a single country. People everywhere can reach it — and increasingly, AI agents hit the service through its API rather than humans. Tellingly, even national patent-search systems now detect and block automated AI access.

"Who performed the act, and in which country?" — the foundational question of patent infringement — quietly collapses here. This article examines three forces driving that collapse: (1) how region settings and geo-redundancy erase the very location of execution and data, (2) how the 'infringer' becomes ambiguous when your customer is an AI or an API, and (3) the unique enforcement headaches this creates — viewed through both the engineering and the case law.
