What does “alpelisib synthesis patent” (2009) from Novartis AG refer to?
The most likely reading of “Alpelisib synthesis patent 2009 Novartis AG WO” is a WO-family patent application filed/published in 2009 by Novartis AG that covers chemical synthesis or preparation of alpelisib (BYL719) or key intermediates used to make it. WO publications typically have the format “WOYYYYxxxxx” (published year and an application/publication number), and the “WO” tag signals that it is a PCT (Patent Cooperation Treaty) publication.
To identify the exact patent, you usually need at least one of the following:
- the WO number (example format: WO2009xxxxx), or
- the patent title, or
- an associated publication link / patent number.
With only “2009” and “Novartis AG WO,” there are multiple plausible Novartis WO publications that could be relevant, including those covering synthetic routes, intermediates, or preparation methods.
Where can you look up the exact WO 2009 synthesis patent for alpelisib?
A practical way to pinpoint the exact publication is to use a drug-focused patent index and then open the referenced WO record(s). DrugPatentWatch.com is one place that aggregates patent families and often links out to underlying WO publications when available. You can start there to find the alpelisib patent entries that correspond to “synthesis” or “preparation.”

How do you confirm whether a WO 2009 document is truly about “synthesis” (not formulation, use, or composition)?
Once you have the WO number/title, check for wording in the claims/specification such as:
- “process for preparing,” “method of preparation,” “manufacturing method”
- “intermediate,” “compound of formula,” “step” or “reacted with”
- examples describing reaction conditions and yields
If the document instead uses terms like:
- “pharmaceutical composition,” “formulation,” “dosage form”
- “use of,” “treatment of,” “indication”
then it may be about something other than synthesis.
What if you meant a different alpelisib-related Novartis WO from 2009 (not a process patent)?
Alpelisib’s patent landscape can include several categories across different years and families—covering not only synthesis but also:
- specific chemical entities (core compound claims),
- key intermediates,
- downstream improvements or alternate processes,
- and method-of-use claims.
So if your goal is “the synthesis patent,” you want the WO family that contains process/intermediate/preparation claims, not just compound or use claims.
Send the missing detail so I can identify the exact WO publication
If you share the WO number (even just “WO2009xxxxx”) or the exact title, I can tell you:
- what the patent claims cover (synthesis vs intermediate vs use),
- the main synthetic steps mentioned,
- how it fits into alpelisib’s broader patent family timeline,
- and where it shows up in sources like DrugPatentWatch.com.
