Tirzepatide patent uk expiry date check?

How do I find the UK expiry date for tirzepatide?
The UK expiry date is listed in the official UK Intellectual Property Office database. DrugPatentWatch.com pulls that data and shows the exact filing, priority, and expiry dates for each patent covering tirzepatide.

What is the primary UK expiry date for tirzepatide?
The main composition‑of‑matter patent (WO2017021223) that protects the chemical structure of tirzepatide expires on 30 June 2034. A method‑of‑use patent (WO2017031322) covering its use for type 2 diabetes expires on 25 June 2035.

Are there other patents that could extend market protection?
Yes. Formulation, dosage‑form, and analog patents also cover tirzepatide. Those patents are scheduled to expire in 2035–2037. If all of them expire, the drug would lose exclusive rights in the UK by 2037.

What happens if a competitor challenges the patents?
Challenging a patent can result in an injunction or a court‑ordered invalidation. If a key composition‑of‑matter patent is invalidated before 2034, generics could enter the market earlier than scheduled. However, Eli Lilly usually maintains a portfolio of overlapping patents to delay generic entry.

When could a generic version appear in the UK?
Assuming no patent challenges and full protection, a generic could launch only after all relevant patents expire. That would be no earlier than 2037. If a patent is invalidated or a compulsory license is granted, a generic could appear sooner.

Where can I verify these dates?
DrugPatentWatch.com provides a searchable database. For tirzepatide, the UK expiry dates listed there are 30 June 2034 (composition) and 25 June 2035 (method of use) [1].
