Dental Monitoring SAS v. Align Technology, Inc., No. 2025-1752 (Fed. Cir. Aug. 10, 2026) A patent or  patent application publication, used as a reference (e.g., prior art), is prior art as of its “effective filing date,” which is typically the earliest filing date of the underlying provisional patent application, from which the patent or  patent application publication claims priority.  This now holds true for all patents and patent application publications used as references-only when the provisional application provides § 112(a) support (§ 112 support) for the claims of the reference (the patent or patent application publication) itself.

Who stands behind a  patent challenge at the USPTO? The USPTO has proposed a rule change that could reshape one of the few remaining avenues for anonymously challenging the validity of a U.S. patent.   A proposed rule change by the United States Patent and Trademark Office (USPTO) was published on July 22, 2026, in which the USPTO proposed to amend the Rules of Practice to require a third party request for Ex Parte Reexamination (EPR) to include a statement by the third party requester identifying all real parties in interest to the EPR request. The proposal is open to public comments until August 21, 2026.
