When does the Cabtreo patent expire?
Patent expiration timing depends on the exact patent(s) listed for Cabtreo and whether any exclusivity extensions apply. In practice, a drug can have multiple relevant IP layers (for example, one or more composition/formulation patents plus other protective patents), so the effective “last day” for generic competition often hinges on the latest expiring listed protection.

Why do there seem to be multiple Cabtreo patents?
It is common for an acne/topical product to have several patents in force at different times, covering different claim categories, such as:
- the drug’s composition or formulation,
- the manufacturing process,
- device or container-related claims (where applicable),
- and sometimes packaging or method-of-use claims.
That can make it look like “the Cabtreo patent” is more than one patent. The DrugPatentWatch entry typically shows the set of patents associated with the product so you can compare their individual expiration dates.
Are companies trying to challenge the Cabtreo patents?
If a generic or competitor files an application that relies on the branded product’s reference, they may also challenge specific listed patents.

What do I need to look up if I want the exact patent number(s)?
To identify the exact Cabtreo patent(s), you usually need one of the following:
- the product’s legal name/active ingredient (tazarotene),
- the company/assignee listed for Cabtreo,
- the patent numbers shown on a database entry,
- or the country (US vs. EP vs. JP), since “Cabtreo patent” can mean different national filings.
If you tell me the country you care about (US only, for example) and the company name shown on the Cabtreo label, I can narrow what to look for within the available patent records.
