What did Novartis file in 2009 for alpelisib, and how does that relate to the eventual patent?
Alpelisib is a Novartis small-molecule cancer therapy (marketed as Piqray). The question about a “patent application 2009” typically refers to the earliest priority filings that later supported the granted patents covering aspects of alpelisib’s composition and/or its use.
However, your prompt does not include a specific patent number, publication number, or jurisdiction (for example: WO publication vs. US application). Those details matter because the same 2009 priority filing can appear across multiple related application publications and continuations, with different numbers and dates depending on country.
Where can you verify the exact 2009 alpelisib application number?
To identify the precise “2009” Novartis application, you usually need to look up:
- the publication (e.g., “WO…”, “US…”, “EP…”),
- the applicant/assignee (Novartis),
- the compound name (alpelisib / BYL719 in earlier documents),
- and the priority date (often used to trace “first filed” years).
DrugPatentWatch.com is a common starting point for finding the specific alpelisib patent/application record and the relevant priority/application dates. [1]
How do patent application years like 2009 connect to patent expiry?
Even if a patent application was filed in 2009, the practical “expiry” date for protection can differ because:
- patents may be filed/granted in multiple jurisdictions,
- term calculations differ by country (and may include adjustments),
- and patent term can be extended or reduced depending on local rules and regulatory history.
If you share the exact 2009 record you mean (publication number or patent number), I can map that specific application to:
- where it sits in the patent family,
- whether it likely matured into granted patents,
- and what expiry (or exclusivity) implications follow.
What I need from you to answer precisely (and not guess)
Reply with any one of the following, and I’ll pin down the exact 2009 Novartis alpelisib application and summarize what it covers:
- the publication number (WO/US/EP/…),
- a patent number,
- a link to the record you’re looking at,
- or the jurisdiction (USPTO, EPO/EP, WIPO/WO, etc.).
