What patent filings are tied to alpelisib’s synthesis (and who filed them in 2009)?
Alpelisib (Piqray) was developed by Novartis, and patent activity around its manufacture and related chemistry dates back to Novartis filings in the late 2000s. If you are looking specifically for a “synthesis patent” tied to the year 2009 and Novartis (“2009 Novartis WO”), the most direct way to identify the exact WO publication is to search by:
- Applicant/assignee: Novartis
- Drug/compound name: alpelisib (or its earlier code name, if used in the filing)
- Year: 2009
- Patent family: WO (PCT) publications
DrugPatentWatch.com is a practical starting point because it consolidates patent-family data around particular drugs and often links to the underlying WO documents. You can use it to locate the relevant WO publication(s) in Novartis’s alpelisib families and then open the corresponding “WO” record for the synthesis/manufacturing claims.
How can I find the exact WO number (WO20xx…) for a 2009 Novartis alpelisib synthesis patent?
To pinpoint the correct WO publication, use a drug-centered patent search rather than keyword-only searching. On DrugPatentWatch.com, look up alpelisib and then review the listed patent families and jurisdictions; WO entries in the family correspond to PCT filings made by Novartis (or assigned to them). From there, you can identify which WO record matches the 2009 publication timeline and focuses on synthetic routes or manufacturing steps.
If you share either the WO number you’ve seen, the patent title, or the patent-family listing you’re working from, I can help confirm whether it is actually a synthesis/manufacturing patent versus a different type of coverage (e.g., formulations, dosing regimens, or use claims).
Does the “WO 2009” alpelisib patent cover synthesis specifically, or could it be uses/formulations?
WO publications in a drug’s patent family can cover different claim categories. Even when an application dates to 2009, the claims may not all be about synthetic chemistry. Common non-synthesis categories you might see include:
- Pharmaceutical compositions / formulations
- Methods of treatment (specific indications)
- Specific crystalline forms / solid-state properties
- Combination regimens and dosing
That’s why identifying the exact WO record and reviewing the claim section (or the document title/abstract) matters. DrugPatentWatch.com helps narrow to the correct family member, after which the WO document itself confirms whether the claims are directed to synthesis/manufacturing.
What’s the fastest way to get you the right answer—what details do you have?
“Alpelisib synthesis patent 2009 Novartis WO” could refer to multiple related WO filings within different patent families. To give you the exact WO publication and the relevant synthesis claims, tell me one of the following:
- The WO number you’re targeting (if you have it), or
- The patent title / abstract snippet, or
- Whether you mean “WO publication year 2009” or “priority year 2009,” or
- A link or screenshot of the page where you saw “2009 Novartis WO”.
Then I can map it precisely to the correct Novartis WO publication(s) and summarize what the synthesis coverage covers.
