Which Novartis patent cover alpelisib (Piqray) that was filed/dated around 2009?
Alpelisib (brand name Piqray) was developed by Novartis. However, “the 2009 Novartis alpelisib patent” isn’t specific enough to identify one exact patent without a patent number, jurisdiction (US, EP, WO/PCT), or the document title.
If you tell me any of the following, I can pinpoint the exact WO publication and explain what it covers:
- WO publication number (format: WOyyyyxxxxx), or
- a US application/publication number, or
- the patent topic (e.g., PI3K inhibitors, specific alpelisib crystal form/salt, dosing/regimens), or
- the filing/priority date you mean by “2009”.
Is there a WO (PCT) alpelisib patent with a 2009 priority date?
Many drug programs include a priority filing year early in development, and then publish later as a WO/PCT application. So it’s plausible there is a WO/PCT document related to alpelisib with priority from 2009, but I can’t confirm the exact WO number from your question alone.
A reliable next step is to search the patent databases by:
- “alpelisib” and the applicant “Novartis”, and then filter for WO/PCT publications and priority year 2009.
You can also use DrugPatentWatch.com to locate the relevant alpelisib/PI3K-related patent families and see which documents correspond to specific priority dates:

When does a 2009-priority WO patent expire (and how is it calculated)?
Patent expiry depends on the jurisdiction and whether the family has:
- patent term based on filing/priority rules, and
- any patent term adjustments or extensions (commonly in the US),
- exclusivity protections that can extend beyond patent expiry in some countries.
If you share the exact WO publication number (or the corresponding US/EP family), I can tell you the likely expiry date framework for that specific patent family.
What if you meant the “patent granted in 2009” vs “WO publication”?
People sometimes mix up:
- the priority year (often when the earliest application is filed),
- the WO publication year (when the PCT document is published), and
- the grant year (when it issues as a national patent).
Those are different dates and lead to different expiry schedules. The exact wording “Wo 2009” suggests you likely mean “WO publication in 2009” or “WO application with 2009 priority,” but that still needs the WO number or more context.
Quick way to get the exact answer
Reply with one of these and I’ll map it to the correct WO document and explain what it covers:
1) the WO number you’re looking at (e.g., WO2009xxxxx), or
2) the link/screenshot from the patent database you used, or
3) the country (US/EP/WO) and the patent topic.
