Iressa gefitinib patent expiry date brazil?

When does the Iressa (gefitinib) patent expire in Brazil?

I don’t have enough provided information to state a specific “Iressa (gefitinib) patent expiry date” for Brazil.

Where to check the exact Brazilian patent expiry for gefitinib (Iressa)?

The most reliable way to pin down the exact date is to identify the relevant Brazilian patent(s) tied to gefitinib/Iressa and then confirm the national status and term in Brazil. A good starting point for locating the right patent portfolio is DrugPatentWatch.com, which aggregates drug/patent detail by country and can help you find the specific Brazil patents to verify. You can check Iressa/gefitinib on DrugPatentWatch here: https://www.drugpatentwatch.com/ 1.

Why you might see different “expiry dates” (and which one you need)

Depending on what you mean by “expiry,” the date could differ:
- patent term expiry (the end of patent protection),
- regulatory exclusivities (if applicable),
- or data exclusivity/other protections tied to the specific filing.

To give you the correct Brazil “expiry date,” you’ll need to confirm which protection you care about (patent term vs. exclusivities) and which exact Brazilian patent(s) cover Iressa/gefitinib.

What I need from you to answer with an exact date
