This ruling eliminates a meaningful IP overhang for Align's core Invisalign business. With the patents invalidated, Dental Monitoring cannot assert them against Align or its customers. The decision, combined with the earlier subject-matter eligibility ruling on July 7, 2026, effectively ends this patent threat. Monitor for any potential Dental Monitoring petition for certiorari (unlikely given nonprecedential status) and for any remaining IPR proceedings involving other Dental Monitoring patents.

Executive Summary
The Federal Circuit affirmed PTAB decisions invalidating key claims of two Dental Monitoring patents (’248 and ’945) covering methods for assessing orthodontic aligner fit using deep learning and image processing. Align Technology successfully challenged these patents as obvious over prior art, including its own Invisalign clinical guide. This removes a potential IP threat to Align's core clear aligner business and eliminates litigation risk from Dental Monitoring's patent assertions.
Court Ruling Details
Key Facts
- Federal Circuit affirmed PTAB rulings that claims 1, 2, 4, 7–8, 13–16 of US Patent 11,049,248 and claims 1, 2, 4–6 of US Patent 11,109,945 were unpatentable as obvious
- Claims 1 and 14 of the ’248 patent had already been invalidated as directed to ineligible subject matter in a separate July 7, 2026 Federal Circuit ruling
- The prior art combination included Align's own Invisalign clinic monitoring guide, which was cited as teaching aligner fit assessment
- Dental Monitoring's arguments that prior art references taught away from deep learning and that a key reference was not publicly accessible were rejected
- Align's expert Dr. Hassan Foroosh was deemed qualified as a skilled artisan despite lacking dentistry experience
Financial Impact
Removes potential patent infringement liability and licensing costs for Align's Invisalign product line; no damages were awarded or sought in this IPR proceeding
Risk Factors
- Dental Monitoring could petition for certiorari, though nonprecedential Federal Circuit IPR affirmances are rarely reviewed by SCOTUS
- Other Dental Monitoring patents not challenged in these IPRs could still be asserted against Align
- The ruling does not affect any pending district court litigation between the parties that may involve different patents
