What patent is “Breyanzi” actually referring to, and why the date can vary?
Breyanzi (lisocabtagene maraleucel) is a cell therapy, so “Breyanzi patent” usually points to the protection for one of several things: the underlying biologic/product, manufacturing process, specific genetic constructs, or methods of treating certain patients. Because different patent families expire on different dates (and some may have term adjustments or extensions), the “Breyanzi patent expiry” answer depends on which country and which specific patent (or patent family) someone means.
When do Breyanzi’s key protections typically end?
I don’t have the specific patent number(s), jurisdiction (US/EU/UK/etc.), or the cited sources that list Breyanzi’s expiry dates. Without that, any specific “expires on [date]” answer would be guesswork.
How to get the exact expiry date you need
To determine the correct expiry date, you generally need:
- The country/jurisdiction (e.g., US vs. Europe)
- The exact patent number(s) (or the patent family for the relevant protection)
- Whether there are term extensions/adjustments (common in drug-biologic patent landscapes)
If you share the jurisdiction (US or EU) and either the patent number you’re looking at or a link/name of the patent listing you mean by “Breyanzi patent,” I can help you pinpoint the expiration timing for that exact patent family.
If you mean “market exclusivity” rather than a patent, the date will be different
People sometimes use “patent expire” to mean “when biosimilars or competitors can enter.” That is controlled by a mix of:
- patent expiration
- regulatory exclusivities (which can differ from patent terms)
- exclusivity for indications
So the date may not match the end of the latest patent.
Next step
Tell me which you mean:
1) US patents for Breyanzi (and if you have a patent number, paste it), or
2) EU/UK patents, or
3) market exclusivity/when biosimilars can compete.
Then I can give a precise expiration date tied to the right legal protection.
