Federal Circuit Rules Deep Learning Dental-Analysis Patents Ineligible Under Section 101

The U.S. Court of Appeals for the Federal Circuit has affirmed a district court ruling invalidating two Dental Monitoring SAS patents covering AI-based orthodontic image analysis. The court found that U.S. Patents 11,049,248 and 10,755,409 — which claim methods for assessing and analyzing dental arch images using deep learning — are directed to ineligible subject matter under 35 U.S.C. § 101 in the case Dental Monitoring SAS v. Align Technology, Inc.

The decision is notable for the broader AI patent landscape, as it signals continued judicial skepticism toward patent claims that apply deep learning techniques to domain-specific analytical tasks without sufficiently concrete, patent-eligible inventive steps. Companies seeking IP protection for AI-driven diagnostic or analytical workflows may need to revisit how their claims are structured in light of this ruling.
