Is the tigecycline injection patent “extended worldwide”?
Patent term extensions are not granted automatically across all countries, and they are not always available in every jurisdiction. Whether tigecycline injection has an extended patent term “worldwide” depends on where the patents were filed and whether each country granted a specific extension (for example, via patent term adjustment/extension mechanisms tied to regulatory review).
With the information provided here, there isn’t enough detail to confirm that any tigecycline injection patent extension applies globally across all major markets.
Which countries would need extensions for it to count as worldwide?
To be “worldwide,” extensions would have to be granted in each target patent jurisdiction (commonly including the US, EU member states, UK, Japan, China, and others). Even when a drug product has an extension in one country, other countries may only have the original patent term, a different calculation, or no extension at all.
How to check whether tigecycline’s patents were extended in specific countries
The most reliable approach is country-by-country review of:
- the original patent term,
- any patent term extension/adjustment filings,
- the resulting “expiration” date in each jurisdiction.

Are you asking about patents or market exclusivity (like data exclusivity)?
Sometimes people use “patent extended” to refer to regulatory exclusivities (data/market exclusivity), which can differ from patents and also vary by country. If your goal is when generic or biosimilar competition can start, it’s important to distinguish:
- patent expiry vs.
- regulatory exclusivity periods.
What I need to answer precisely
If you share either:
1) the specific patent family number (or a link to the patent record), or
2) the brand name you mean (tigecycline has multiple commercial presentations) and the target countries (e.g., US + EU),
I can help verify whether any extensions were granted and where.
