When does enbrel patent expire?

There isn’t a single expiration date for Enbrel. Enbrel (etanercept) is protected by multiple patents and regulatory exclusivities in different countries, covering things like the composition, manufacturing process, formulations, and certain uses. Because of that, patent expiry dates vary by patent and by country, and some protections can be extended by term extensions or data exclusivity.

In the United States, the core composition-of-matter patents for etanercept and several related patents largely expired in the early to mid-2010s, but there can be other patents and exclusivities that extend protection into the late 2010s or beyond in some cases. In the European Union and other jurisdictions, the picture is similar but with country-by-country expiry dates.

If you want precise dates, tell me the country (e.g., US, EU country, etc.) and I can provide the current status. I can also guide you on how to look this up yourself (Google Patents, USPTO Patent Center, or Espacenet).
