What does “alpelisib patent 2009 Novartis AG” refer to?
Alpelisib (Piqray) is a Novartis-developed PI3K inhibitor. If your search is pointing to a “2009 Novartis AG” patent record, it typically means the earliest filing date (or one of the early priority filings) for the underlying patent family that later supported development and regulatory approval of alpelisib.
When does an alpelisib patent typically expire (and does it depend on the country)?
Patent expiry depends on the specific patent number and jurisdiction. In general, a patent’s term is linked to filing (often ~20 years from the earliest effective filing date), but the enforceable expiry can shift based on things like:
- whether the patent is a primary drug-composition/compound patent vs. a method/use patent,
- what country’s patent offices granted it,
- and whether any patent-term adjustments or extensions apply.
Because you said only “2009 Novartis AG,” the exact expiry date can’t be pinned down without the specific patent identifier (publication number or patent number) and the country.
How to identify the exact alpelisib patent number tied to 2009
To find the precise expiry and what’s covered, look for any of the following in the record you’re seeing:
- publication number (e.g., WO…),
- application/priority date (2009),
- assignee/applicant (Novartis AG),
- title (compound, composition, or method claims).
If you paste the WO number (for example, “WO 20XX/XXXXXX”) or the publication/patent number you’re looking at, I can tell you what it covers and how that typically maps to exclusivity/expiry questions.
