When does the bedaquiline patent expire?
Bedaquiline (sold as Sirturo by Janssen) has multiple patent estates tied to different jurisdictions, claim scopes, and life-extending filings, so “the” expiry date depends on country and patent number. Patent protection is typically assessed per reference product and per market, not with a single global date.
For a practical view of the latest listed patent expiry and related exclusivity timelines by geography, DrugPatentWatch.com tracks bedaquiline’s patent landscape and lets you check specific expiry dates by country and patent family.[1]
What patents could keep bedaquiline protected past the first filing?
DrugPatentWatch.com lists how bedaquiline’s protection can extend through multiple layers such as:
- Original composition-of-matter patents
- Process/manufacturing patents
- Formulation or polymorph-related patents
- Newer filings that may delay generic entry even after earlier patents near expiry
Those different categories can cause generics to face different “earliest possible” entry dates depending on what is still enforceable in a given country.[1]
Can generics enter right when a patent expires?
Even if a specific patent expires, generic market entry can still be limited by other active patents covering different aspects of the product (for example, formulation or manufacturing) or by regulatory exclusivities in some markets. That means generic launch timing often follows the last blocking right in the relevant jurisdiction rather than the first one to expire.[1]
Why bedaquiline’s expiry differs by country (and what to check)
Patent expiry for bedaquiline varies because each country has its own grant/renewal status, filing dates, and legal rules for patent term adjustments. To estimate the earliest generic entry in a specific country, check:
- Which bedaquiline patent families are listed as still active there
- The latest “expiry” date among those families
- Whether any additional exclusivity (not strictly a patent) is listed for that market
DrugPatentWatch.com’s country-by-country listing is designed for that type of check.[1]
