What does “Novartis alpelisib synthesis patent 2009” refer to?
Alpelisib (Piqray) is a Novartis PI3K-alpha inhibitor. A “synthesis patent” typically means a patent that claims how to make the drug (a chemical manufacturing process) or key intermediates/steps in its preparation, rather than claims about the final compound only.
Because “synthesis patent 2009” is ambiguous on its own (there may be multiple 2009-dated filings, family members, and jurisdictions), the most accurate way to identify the exact patent is to match the date (2009), applicant/assignee (Novartis), and the exact title/claim language (e.g., “process for preparing alpelisib,” “preparation of [intermediate],” or “synthetic route to [alpelisib]”).
Which 2009 alpelisib patents should you check first?
If you’re looking specifically for a 2009 synthesis/manufacturing process, search in patent-family records for entries where:
- Applicant/assignee includes Novartis (or a Novartis entity)
- The document date or priority date is 2009
- The title or abstract mentions a process, method, preparation, or intermediate synthesis for alpelisib (or the immediate synthetic precursor)
In practice, this is usually done by starting from a known reference point (for example, a granted or published alpelisib patent) and then expanding to the “family” to find related process/intermediate patents with 2009 priority.
When does a 2009 synthesis patent typically expire?
A typical patent term is 20 years from the earliest non-provisional priority date, subject to adjustments (jurisdiction-specific) and whether the claim set is granted and maintained. So a 2009 priority generally implies a long window into the 2020s, but the exact expiry depends on:
- The jurisdiction (US/EP/WO, etc.)
- Whether there were term adjustments or extensions
- Whether the specific claims (process claims) survive appeals/maintenance
