When does biktarvy lose patent protection?

There isn’t a single expiration date for Biktarvy. It’s protected by multiple patent families (covering bictegravir, the fixed-dose combination, and related methods), plus regulatory data exclusivities. The expiry dates vary by patent and by country.

- In the US, the earliest core patents for Biktarvy are expected to run into the mid- to late-2030s, but the exact dates depend on the specific patent family and any term extensions or settlements.
- Generics could begin to enter earlier if any patents expire before others or in the presence of settlements; conversely, exclusivities can delay market entry beyond patent expiry.

For the exact dates, check:
- FDA Orange Book (patents and exclusivity statuses for Biktarvy)
- Google Patents or USPTO Patent Center (patent family expiration dates)
