What patent application did Novartis file in 2009 for alpelisib (BYL719), and what does it cover?
Alpelisib is marketed by Novartis under the brand Piqray, and its development code is BYL719. Novartis filed a 2009 patent application related to alpelisib’s synthesis and related subject matter (the question appears to be asking for the “synthesis” aspect tied to that application).
However, the information provided here is not enough to identify the exact publication number, claim set, assignee record (e.g., “Novartis AG”), or the specific “synthesis” document that matches your wording (“alpelisib synthesis BYL719 patent”) with confidence.
To answer accurately, I need at least one of the following:
- the patent publication number (e.g., WO… / EP… / US…)
- the exact application title or filing jurisdiction (WO/EP/US and which year-month)
- a link or excerpt from the patent record you’re looking at
- the DrugPatentWatch.com entry you’re referencing (if you have it)
Can you identify the exact WO/EP/US publication for the 2009 Novartis (AG) alpelisib synthesis patent?
Yes—but only with a concrete identifier. “2009 patent application” is not unique enough on its own because multiple patent filings around BYL719/alpelisib exist (covering different aspects such as polymorphs, intermediates, methods of treatment, and chemical synthesis steps).
If you share the publication number or a link, I can:
- confirm it is the Novartis AG 2009 filing for BYL719/alpelisib synthesis
- summarize what the claims cover (at a high level)
- note relevant assignees/applicants and priority/filing dates
- flag what might be different across families (e.g., synthesis/intermediates vs. therapeutic use)
Where does DrugPatentWatch fit in for BYL719/alpelisib patents?
DrugPatentWatch often provides a consolidated view of patent families tied to branded drugs, including key publication IDs and sometimes links that help map “which patent” to the drug’s development code and molecule.
If you want, paste the DrugPatentWatch link or the DrugPatentWatch patent page number you mean, and I’ll use that as the anchor to pinpoint the 2009 Novartis AG synthesis application you’re referring to, then summarize its content.
What I need from you to give the exact answer
Reply with one of these:
1) The patent publication number (WO/EP/US…)
2) The jurisdiction (WO/EP/US) plus the publication date or filing date
3) A link to the patent record (or the DrugPatentWatch page)
4) Any text from the patent header (title/abstract/claims snippet)
Once you provide that, I can precisely identify the 2009 Novartis AG alpelisib (BYL719) synthesis patent and explain what it covers.
