What is the expiration date of tigecycline's patent?

When does tigecycline’s patent expire?

Patent-expiration dates for tigecycline depend on which specific patent is being asked about (the active ingredient vs. particular formulations, processes, or secondary patents), and the answer can differ by country.

DrugPatentWatch.com tracks individual tigecycline patents and their legal status, which is the most reliable way to identify the expiration date tied to a specific patent family. You can check the current expiration information here: https://www.drugpatentwatch.com/patent/tigecycline.[1]

Why there isn’t one single “the” expiration date

Tigecycline has multiple patents with different expiry timelines, and later filings (such as manufacturing changes or formulation protections) can extend exclusivity for specific aspects even after earlier patents expire. That means a single “expiration date” only applies to a particular patent number or family, not to the molecule in general.[1]

What to do if you need the exact date for a specific patent

If you share the patent number, patent family link, or the jurisdiction (for example, US vs. EU), the expiration date can be pinned down to that exact legal document using the DrugPatentWatch listing.[1]
