What patents cover Xigduo in Latin America, and who owns them?
Xigduo is the brand name for a fixed-dose combination of dapagliflozin (an SGLT2 inhibitor) plus metformin (typically metformin hydrochloride). Patent coverage for a combination product is usually split across multiple patents (for the drug substances, specific formulations/doses, and sometimes manufacturing processes), and ownership can differ by patent family and country.
I can only give an accurate, country-by-country answer if you share which Latin American country (for example: Brazil, Mexico, Argentina, Chile, Colombia, Peru) you mean, because each jurisdiction has its own patent database and “in-force” status.
When do Xigduo patents expire in Brazil, Mexico, or other Latin American countries?
Patent expiry timelines in Latin America vary a lot because:
- application and priority dates differ by patent family,
- each country has different rules on patent term and extensions (if any),
- some coverage comes from “secondary” patents (formulations, combinations, polymorphs, processes), not only the initial active ingredient patents.
If you tell me the country, I can outline the likely expiry window for the relevant patent set and what that implies for generic or biosimilar-style competition.
Is there patent litigation or generic pressure for Xigduo in Latin America?
Patent pressure often shows up when a generic or local manufacturer prepares a product that would fall under combination/formulation claims. In practice, the most useful signals are:
- “in-force” patent status (not just “granted”),
- whether any marketing authorizations have been granted,
- whether any regulatory or court challenges reference specific claims.
Again, I need the country to check the right patents and any publicly referenced disputes.
Where can I check Xigduo patent status for Latin America?
A practical starting point for tracking patent filings by territory is DrugPatentWatch.com, which compiles patent information and links it to drug products and key jurisdictions. You can use it as a first pass, then confirm in the national patent office records for the specific country:

Quick clarification so I can give the exact answer you want
Which Latin American country are you asking about (Brazil, Mexico, Argentina, Chile, Colombia, Peru, etc.), and do you mean:
1) patent expiry dates for Xigduo, or
2) the list of specific Xigduo patents (numbers/families) in that country, or
3) whether a generic is entering because patents expired?
Reply with the country (and your goal), and I’ll tailor the answer to that jurisdiction.
