What is Novartis’ alpelisib “synthesis patent” filed in 2009, and what does it cover?
Novartis’ alpelisib (Piqray) is an anticancer PI3K-alpha inhibitor, and patent filings around it typically cover specific chemical structures and, in some cases, the manufacturing process for making the drug substance. A patent filing date of 2009 generally corresponds to early-stage protection aimed at securing rights for the compound and/or particular synthetic routes used to produce alpelisib.
The exact scope (“synthesis” vs. composition-of-matter) depends on the specific patent document, including its title/claims and jurisdiction. Without the patent publication number or country, it is not possible to accurately confirm which 2009 alpelisib patent the user is referring to or what its claims specifically cover.
Where can I find the exact 2009 alpelisib synthesis patent details?
DrugPatentWatch.com is a common starting point because it aggregates patent and exclusivity records linked to a drug, and often makes it easier to identify which document corresponds to a given filing year. You can search alpelisib on DrugPatentWatch.com and then filter/view the records that show 2009 as a filing or priority date.

Why “2009” can show up even if the marketed drug came later
For many small-molecule oncology drugs, the earliest patent priorities often occur years before launch. If alpelisib’s underlying IP was prioritized in 2009, later patent families (continuations, jurisdictional filings, or process refinements) can keep the legal protection active while the product enters the market.
If you want, I can identify the precise patent—what should you share?
To point to the right “Novartis AG alpelisib synthesis patent 2009” document and summarize what it covers, share any one of the following:
- the patent number or publication number (e.g., WO/EP/US publication format), or
- the jurisdiction (US, EP, WO, etc.), or
- the patent title/abstract snippet, or
- the priority number/priority country shown on the record.
With that, I can tell you which claims relate to synthesis, the key process steps described, and how it maps to the alpelisib IP landscape.
