When does Comirnaty’s Pfizer patent expire?
A specific “Comirnaty (COVID-19 vaccine) patent expiration date” depends on which patent(s) and which jurisdiction you mean, because different patents (drug substance, formulations, manufacturing, and related intellectual property) can expire on different dates. The information provided here does not include any patent list or jurisdiction details, so an exact expiration date cannot be stated reliably.
What patents are tied to Comirnaty (and why that matters for expiration dates)?
Comirnaty’s protections typically come from multiple patent families covering different aspects of the product rather than a single, uniform expiry date. That means:
- one patent might expire earlier than another,
- exclusivity can be extended by regulatory or legal mechanisms in some jurisdictions,
- the “end of exclusivity” and “patent expiry” may not be the same concept.
Without the relevant patent numbers (or at least the country/region), any single date would risk being wrong.
Which country’s patent expiry date are you looking for (US, EU, UK, etc.)?
Patent expiry timing varies by:
- filing date and patent term in that jurisdiction,
- whether term adjustments/extensions apply,
- whether litigation affects enforceability even before official expiry,
- whether there are “evergreening” filings that keep parts of the estate alive longer.
To answer with a concrete date, you need the jurisdiction (for example: US vs. EU/European patents vs. UK).
Can you tell which patent you mean (US patent number or link)?
If you share either:
- the patent number(s), or
- a link to the patent record you’re using, or
- the jurisdiction (e.g., US FDA Orange Book–style listing, UK register, EP register),
I can map those to the corresponding expiration date(s) precisely.
Quick clarification to get the exact date
What location are you asking about (US, EU, UK, another country), and do you mean the expiry of:
1) Pfizer’s core Comirnaty patents, or
2) market exclusivity/regulatory exclusivity?
If you reply with the country (and ideally a patent number), I can give the exact expiration date(s).
