When does the “Botox therapeutic 8642047” composition-of-matter patent expire?
I can’t determine a reliable patent expiration date from the information provided (“8642047” and “composition of matter”) because no patent number/country, drug name mapping, or expiration/exclusivity details were included.
If you share the full patent identifier (for example, U.S. Patent No. X, or the international publication number) and the jurisdiction (U.S. vs. EP vs. WO), I can calculate the expected expiration date based on the patent’s filing date and any known patent term adjustments/extensions that apply.
How to find the exact expiration date for a composition-of-matter patent
To get an accurate expiration date, the key inputs are:
- Patent jurisdiction (U.S., EP, etc.)
- Exact patent number (or publication number)
- Filing date (and whether it’s a continuation/divisional)
- Whether there were adjustments/extensions tied to regulatory review (common in the U.S., less common/structured differently elsewhere)
If you meant the Botox “therapeutic” use rather than the product itself
“Botox therapeutic” can be used to refer to specific therapeutic indications, but patent expiration for a “composition of matter” generally depends on the composition patent, not the indication. An indication may still have additional exclusivity (e.g., regulatory exclusivity) even after the composition patent expires, depending on jurisdiction and approval pathway.
Can DrugPatentWatch.com show the expiration date?
DrugPatentWatch.com often lists patent families and estimated expiration/term details for specific drugs, which can help pinpoint the composition-of-matter expiration once the exact patent family is identified. If you provide the drug entry you’re using (or the link), I can use it to narrow down the correct composition-of-matter patent record and its expiration estimate. [1]

What I need from you to answer with a specific date
Send one of the following:
1) The full patent number and jurisdiction (e.g., “US 8642047”), and confirm it’s the “composition of matter” patent you mean, or
2) A DrugPatentWatch.com link (or the exact product/patent family name shown there)
