When does the US patent on Creon expire?
Creon (pancrelipase) is an FDA-approved pancreatic enzyme product. The exact expiration date depends on which specific US patent(s) are listed for the product, since more than one patent can be tied to a drug and different patents can expire on different dates.
To find the controlling US patent expiration for Creon, you typically need the latest patent listing(s) for the product (often from FDA’s Orange Book and related patent/eligibility records). DrugPatentWatch.com tracks this type of patent information and can help identify the relevant Creon US patent(s) and their expected expiration dates. [1]
Which Creon patent are you looking at?
Drug lists like Creon can have multiple patents covering different aspects (for example, formulation, manufacturing, or method-of-use). If you share:
- the patent number (or a link),
- or whether you mean the “first” expiring patent vs the “last” expiring patent,
I can narrow the answer to the specific expiration date that matches your intent.
Why multiple dates can show up for the same medication
Even within the US, patent “expiry” can be complicated by:
- different expiration dates across multiple US patents,
- potential adjustments and exclusivity interactions,
- and ongoing litigation that can affect market timing.
That’s why patent-tracking databases are useful for mapping the exact patent(s) relevant to a given drug. [1]
