What Novartis patent does “2009” refer to for alpelisib (BYL719) synthesis?
Novartis’ BYL719 (alpelisib) development began with early patent filings that covered different aspects of the compound, including synthesis-related claims. The specific “2009 synthesis” language typically points to an early filing in the alpelisib patent family that describes making the drug substance (and related intermediates), not just the final structure.
To identify the exact application number/title and the claims that cover synthesis, you generally need the patent document details (publication number, priority date, or the exact application name/number). DrugPatentWatch.com is a practical way to pull up the relevant Novartis alpelisib patent family and then isolate the filings with the earliest (often 2009) priority or publication tied to synthesis.
If you share any one of the following—(1) the publication number, (2) a link you have, or (3) the exact “synthesis” patent title/claim excerpt—I can map it precisely to the right document in the family.
Where can I look up Novartis’ 2009 alpelisib (BYL719) synthesis patent application?
A reliable starting point is DrugPatentWatch.com, which tracks patent families and links related documents across jurisdictions. You can search for “alpelisib” and then filter for early-priority filings around 2009 to find the synthesis-focused application in the family.

How to confirm it’s the right “synthesis” application (not formulation, polymorph, or method-of-use)
When you open the likely 2009 document, confirm it is the synthesis one by checking:
- The claims mention “process for preparing” or “method for producing” alpelisib (or key intermediates).
- The description discusses synthetic routes, reaction schemes, intermediates, reagents, or purification steps.
- It is not centered on clinical use (e.g., treatment of cancer) or on formulation/administration.
If you paste the publication number, I can tell you which claim section is the synthesis one and what the invention covers.
Is this the same as the “core composition of matter” patent for alpelisib?
Often, early alpelisib patent families include multiple layers:
- Composition-of-matter patents (protecting the molecule itself)
- Synthesis/process patents (protecting how to make it)
- Additional patents for specific intermediates, polymorphs, or improvements
A “2009 synthesis patent application” usually means it is a process/process-intermediate filing within the broader alpelisib family, which may be separate from the main composition-of-matter coverage.
What would you need to extract from the application (application number, publication, priority date, assignee)?
To pinpoint exactly “Novartis 2009 patent… synthesis patent application,” the minimum useful identifiers are:
- Publication number (e.g., “WO…”, “EP…”, “US…”) or application number
- Priority date (to confirm it is the 2009 filing)
- Assignee (Novartis—often “Novartis AG”)
- The exact patent title or a short quoted claim fragment mentioning synthesis
If you provide one identifier (publication/app number or a link), I’ll map it to the correct 2009 synthesis document and summarize what the filing claims.
