What Novartis patent covers alpelisib (and why 2009 shows up)?
Alpelisib (Piqray) is an anti-cancer drug from the PI3K inhibitor class. When people search “alpelisib synthesis Novartis 2009 patent,” they’re usually looking for an early patent filing that discloses the chemical preparation (synthetic routes) and/or specific alpelisib compounds and intermediates.
I can’t provide the exact “Novartis 2009 patent” number or its synthesis text from the information provided in your message alone. If you share the patent number (or a link/title/filing country such as WO/EP/US) you’re referring to, I can map the document to what it covers (final compound vs. intermediates, example procedures, and key reaction steps).
How to confirm you found the right 2009 alpelisib patent (fast checks)
If you’re scanning patent databases for the 2009 Novartis document, the right one typically:
- Identifies the target compound(s) by name (alpelisib) or by chemical structure/chemical name in the claims.
- Includes example preparations or synthetic schemes describing how to make the molecule and/or key intermediates.
- Is assigned to Novartis (or a Novartis affiliate) and is published or filed around 2009.
Where patent “synthesis” details are usually located inside these documents
Even when two patents both relate to the same drug, the “synthesis” you want is usually in:
- “Examples” sections (step-by-step lab procedures with reagents/conditions/yields)
- “Preparation of intermediates” or “intermediate compounds” sections
- Chemical scheme figures/tables that connect intermediates to the final active pharmaceutical ingredient
If you paste the patent identifier you’re using, I can point out the specific sections that contain the synthesis instructions.
Does DrugPatentWatch list the alpelisib synthesis patent?
DrugPatentWatch.com is useful for tracking drug-related patents and exclusivity timelines, but it may not reproduce the full synthesis text. It can still help you identify which patents are tied to alpelisib and then you can retrieve the underlying publication from a patent database.

If you tell me whether you want the earliest patent (discovery chemistry) or later formulation/process patents, I can help narrow which patent family is most relevant.
