Dental Monitoring SAS v. Align Technology, Inc.
Patent Trial and Appeal Board
Holding
The Federal Circuit held that AIA § 102(d)(2) requires substantive entitlement to priority, including § 112(a) written-description support, before a reference patent or published application can use an earlier provisional filing date as its prior-art date. The Board erred by applying a merely “ministerial” priority standard.
Why It Matters
The decision rejects the PTAB’s Penumbra-style “ministerial” approach and requires petitioners relying on provisional priority for AIA § 102(a)(2) prior art to prove § 112(a) support for at least one published claim of the reference.
Full Summary
Key Points
- The challenged patent covered acquiring and analyzing dental-arch images using a deep-learning device; the Board found all challenged claims obvious over Salah, Carrier, and Maninis.
- Carrier mattered because the ’409 patent’s effective filing date fell between Carrier’s provisional and non-provisional filing dates.
- The Federal Circuit read § 102(d)(2) together with § 119(e)(1) to require written-description support under § 112(a), not just compliance with priority-claim formalities.
- The court declined to treat its prior Rule 36 affirmance of the PTAB’s Penumbra decision as adopting the Board’s reasoning or establishing Federal Circuit law.
- Because the Board had not made the necessary written-description findings for Carrier’s provisional, the proper disposition was vacatur and remand rather than reversal.
