Xolair patent expiration date?

There isn’t a single “Xolair patent expiration date.” Xolair (omalizumab) is covered by multiple patent families (composition of matter, formulations, methods of use, etc.) and those patents expire at different times in different jurisdictions. In addition, regulatory exclusivities for biologics (data exclusivity, market exclusivity) can affect market entry even after patents lapse.

If you’d like, tell me:
- the jurisdiction (US, EU, UK, etc.)
- which patent type you care about (composition-of-matter patent vs. other patents) or if you want the current status across all Xolair patent families

I can then pull up the exact expiration dates for the relevant patent families or search current status.
