When does the Otezla (apremilast) patent expire in the UK?
The MHRA does not publish a single, plain “Otezla patent expiry date” for the UK in its core drug information. Instead, UK patent and exclusivity timelines depend on the specific patent(s) and any supplementary protection mechanisms linked to the medicine. Because the exact expiry date is patent-by-patent (and can differ by jurisdiction and claim), you need the specific UK patent number(s) for apremilast/Otezla to calculate the expiry accurately.
How do you find the exact UK expiry date for Otezla patents?
In practice, the most reliable way is to identify:
1) The specific UK patents covering apremilast/Otezla (e.g., product and/or formulation/use patents), then
2) Check each patent’s published status and its declared expiry date (which typically ties to the filing/priority date and patent term rules).
You can then cross-check with UK regulatory exclusivity, if any, that could extend market protection beyond a particular patent.
Does MHRA decide patent expiry?
No. The MHRA regulates medicines (authorisation, safety, quality). Patent expiry is a matter of UK intellectual property law and the specific patent’s term, not an MHRA decision. MHRA materials may still be useful for confirming the authorised product details, but not for setting the legal expiry date.
What could delay availability even after a patent expiry date?
Even if a particular patent expires, other protections may still keep exclusivity in place, such as:
- other active patents on apremilast (for different claims, formulations, or medical uses),
- regulatory exclusivity protections (where applicable),
- and ongoing litigation affecting launch timing.
What you can search for next (to get the exact date quickly)
To pin down “MHRA Otezla patent expiry UK,” search the UK patent record for “apremilast” and identify the relevant UK patent family member(s). Once you have the UK patent numbers, the expiry dates come from the patent status record rather than the MHRA.

If you share the specific patent number(s) you’re looking at (or the exact wording of what you found on an MHRA or UK register page), I can help you interpret which expiry date applies in the UK and what it would mean for market protection.
