What Novartis’ 2009 patent covers for alpelisib, and how it relates to Byl719
Alpelisib (also known by the code name BYL719) is the active ingredient in the Novartis medicine Piqray. The key patent question for many searches is not just “who has a patent,” but what each patent in the chain covers (the compound itself, a specific process for making it, or a method of use).
From the information provided here, I can’t verify which specific “2009 Novartis patent” you mean or what its exact claims are (for example, whether it’s a compound patent, an intermediate/synthesis patent, or a use/indication patent). Patent numbers and claim scope matter a lot for determining whether another patent is a direct conflict.
Is “BYL719” itself protected by patents, or is it the marketed drug Piqray?
In practice, patents typically cover one or more of the following for alpelisib/BYL719:
- The chemical entity (alpelisib) and close analogs.
- Specific synthetic routes (how the compound is made).
- Medical uses (which can include combinations and line of therapy, depending on the filing).
Whether a “BYL719 synthesis” patent exists and how it maps to a “2009 Novartis patent” depends on the exact patent family members and claim language.
How to find the exact “2009 Novartis” alpelisib synthesis patent and match it to BYL719
To answer your question precisely (which patent number, what the synthesis/process claims are, and whether another patent like a BYL719 patent overlaps), you need at least one of:
- the patent number (US, EP, WO, etc.), or
- the patent title, or
- the assignee listed on the patent record, or
- a link to the patent document or an entry you saw.
If you share the patent number you’re referring to, I can compare it to other alpelisib-related patents by claim type (compound vs. synthesis vs. method-of-use) and explain what overlaps.
