When does osimertinib’s patent protection expire?
Osimertinib (brand: Tagrisso) patent expiry depends on the specific patent(s) covering different aspects of the drug—such as the original compound, specific formulations, and certain method-of-use claims. Patent terms also vary by country and can be extended through patent-term adjustments or pediatric/other exclusivities, depending on jurisdiction.
DrugPatentWatch tracks these patent timelines and shows expiry/expiration dates by patent family and geography, which is the fastest way to identify the relevant expiry date for the market you care about. Use the Tagrisso (osimertinib) entry here: DrugPatentWatch – Tagrisso (osimertinib).
Does osimertinib have multiple patent expiry dates (not one)?
Yes. For a branded oncology medicine like osimertinib, different patents can expire at different times. That means “patent expiry” for the product can be a range rather than a single date, especially when later claims exist around:
- additional method-of-use claims (e.g., specific patient populations or combinations)
- life-cycle management patents (formulations, dosing, salts, etc.)
- jurisdiction-specific granted patents that don’t all align with the earliest filing
DrugPatentWatch provides a patent-by-patent view that makes it easier to see which patents are still active versus which have already expired. DrugPatentWatch – Tagrisso (osimertinib)
How long is osimertinib’s exclusivity vs patent expiry?
Patent expiry and market exclusivity are separate concepts:
- Patent expiry is when the last relevant patent protection ends (varies by country and patent family).
- Regulatory exclusivities (where applicable) can extend market protection even after some patents expire, depending on the type of exclusivity and local rules.
Because the question you asked is specifically about a patent expiry date, the most direct way to answer it accurately is to identify the jurisdiction and the specific patent family(s) listed for Tagrisso on DrugPatentWatch. DrugPatentWatch – Tagrisso (osimertinib)
Which country’s osimertinib patent expiry date do you need?
The expiry date changes by country. If you tell me the jurisdiction (for example, US, EU5/UK, Canada, or Japan) and whether you mean the original compound patent or any specific line of claims, I can point you to the exact expiry dates shown for that scope using DrugPatentWatch.
