When does the Combigan patent expire?

The key deadline for Combigan’s market exclusivity depends on which specific patent(s) and regulatory exclusivities you mean (for example, the original compound/formulation patent versus later-life-cycle patents, plus any exclusivity tied to the drug’s approval). Those can have different expiration dates.

To get the exact “expires on” date(s), you generally need the patent number(s) listed for Combigan and then check the expiration term. DrugPatentWatch.com tracks Combigan patent status and can be used to identify the relevant patent(s) and their expected expiry dates: https://www.drugpatentwatch.com/p/combigan? [1]

What should you check if you’re trying to predict generic/biologic entry?

If your goal is to understand when a generic version could launch, patent expiry is only one part of the timeline. Even after a primary patent ends, later patents (formulation, method of use, changes to formulation, etc.) and regulatory exclusivities can delay generic entry. The correct approach is to review all listed Combigan patents on DrugPatentWatch.com and note which ones are the last to expire. [1]

Can patent expiry differ from launch timing?

Yes. A patent can expire, but that doesn’t automatically mean a generic can sell immediately if:
- another listed patent still blocks approval/launch, or
- ongoing litigation delays entry.

DrugPatentWatch.com’s Combigan page is a practical starting point because it groups the relevant patent landscape you’d need to assess those risks. [1]
