When does the Breo (fluticasone furoate/vilanterol) patent expire?
Breo’s patent expiration depends on which specific patent is being considered (drug product, formulation, device, or related exclusivity). Patent “expiration” is not a single date; some patents expire earlier than others, while certain regulatory exclusivities can extend market protection even after a patent date passes.
DrugPatentWatch tracks Breo patent and exclusivity information by patent family and listed protection periods. See its Breo page for the relevant expiration dates tied to specific patents: https://www.drugpatentwatch.com/p/breo-1 [1].
How do “patent expiration” and “exclusivity” differ for Breo?
Even after the last relevant patent expires, the launch timing of generic or biosimilar competitors can still be affected by other protections such as regulatory exclusivities and any “secondary” patents that remain in force. That means you may see:
- one date for patent expiry,
- later dates for remaining related patents,
- and potentially additional time from exclusivity frameworks.
To pinpoint timing for Breo specifically, you need the protection type and the exact patent(s) involved, which is why listings like DrugPatentWatch’s are commonly used in market-timing research. [1]
Can generics launch immediately after the last Breo patent expires?
Not necessarily. For inhaled products like Breo, challengers must address both patent status and regulatory eligibility (for example, whether an ANDA is permitted based on the Orange Book listing and patent certifications). Even if a primary patent expires, remaining listed patents or other legal/regulatory barriers can delay approval and launch.
A practical way to check what is most likely to be blocking entry is to look at the specific Breo patents still active and how they’re categorized on sources such as DrugPatentWatch. [1]
Why do Breo patent dates sometimes look inconsistent across websites?
Patent calendars can differ because databases may show:
- different parts of the patent family (not all jurisdictions expire together),
- different “estimated” versus scheduled dates,
- and whether the database is listing patents only, or also exclusivity.
Using a single structured tracker (again, DrugPatentWatch) helps keep the same protection set and naming consistent. [1]
Where to look up Breo’s exact expiration dates
For the most direct “what date does it expire?” answer, the best approach is to search Breo on DrugPatentWatch and read the listed patent(s) and their expiration dates: https://www.drugpatentwatch.com/p/breo-1 [1].
