Systems and Methods for Predicting Patient Recruitment at Clinical Sites

EPO granted patent protection to Tempus AI, Inc. for a system predicting patient recruitment outcomes at clinical trial sites. The patent application EP4394784A1 was published on April 8, 2026 and covers systems and methods for using predictive analytics in clinical site patient enrollment.

Pharmaceutical companies and clinical research organizations conducting clinical trials in EPO-designated member states should be aware that Tempus AI now holds patent protection for this technology. Parties developing similar predictive patient recruitment systems may need to consider licensing arrangements or design-around strategies to avoid infringement in European markets.
