What patent covers asciminib synthesis (and what “WO” usually means)?
“WO” in patent citations typically refers to a WIPO publication number (the international patent application published under the Patent Cooperation Treaty). To identify the exact “asciminib synthesis process” patent, you generally need at least one of the following:
- a full publication number (for example, WOYYYY/NNNNNN),
- the assignee/company name,
- or the specific patent family member (WO vs. EP vs. US).
Your prompt (“Asciminib synthesis process patent wo”) doesn’t include enough identifying detail to pinpoint the exact WO document.
Which company and key claims to search for
When people look for “synthesis process” patents for a drug like asciminib, they usually mean a patent that claims one or more of:
- a specific synthetic route (step-by-step transformations),
- a particular intermediate and how it is made,
- reaction conditions (catalysts, solvents, temperatures, times),
- purification / crystallization steps (often where “process” patents live),
- or salt formation / polymorph control used to make a drug substance.
If you share the assignee (e.g., the company you think holds it) or the WO number you saw, I can help you interpret what the synthesis/process claims cover and how the patent relates to asciminib drug substance manufacturing.

What I need from you to give the exact WO patent and synthesis details
Reply with one of these and I’ll zero in on the correct WO patent and summarize the claimed synthesis/process:
1) the WO publication number you’re referring to, or
2) the company/assignee name, or
3) a link or screenshot text of the patent listing you saw, or
4) the patent title keywords (for example “intermediate”, “preparation”, “crystallization”, “salts”, “process for preparing …”).
