Xcopri patent expiration date?

Xcopri is cenobamate. There isn’t a single expiration date for Xcopri because protection comes from multiple patents (covering the compound itself, its uses, and formulations) plus regulatory data exclusivities. In the U.S.:

- Data exclusivity for cenobamate as a new chemical entity generally runs 5 years from FDA approval (Xcopri was approved in 2019, so that exclusivity would roughly end in 2024, subject to any pediatric or other extensions).
- The main protection for the compound and its uses is via a family of patents, which are typically scheduled to expire in the late 2020s to early 2030s, depending on term adjustments and extensions.

For exact dates, you should check:
- FDA Orange Book listing for Xcopri/cenobamate (patent numbers and expiry dates)
- USPTO Patent Center and Google Patents for the specific family and term details
