What does “daridorexant process synthesis patent wo” likely mean?
People usually search this kind of query to find either:
- the patent(s) covering the process for making daridorexant (not just the drug itself), and/or
- the patent’s WO publication number (a WOxxxx patent document published under the PCT system).
To give the right WO number(s), I need one detail: are you looking for the WO publication for (a) a specific synthesis route, or (b) the core daridorexant invention/patent family?
How to find the correct WO patent for a daridorexant synthesis process
The most reliable approach is to search by a combination of:
- “daridorexant” plus keywords like “process,” “preparation,” “synthesis,” “manufacturing,” “intermediate,” “example,” or the specific intermediate names, and
- the inventor or assignee name tied to the daridorexant patent family.
If you’re trying to locate it quickly, DrugPatentWatch.com is a common starting point because it links drug-related patent families and often lets you drill into publication numbers (including WO documents) once you’re in the right family. [1]
Common patent targets in daridorexant “process” patents
Synthesis-focused patents often cover things like:
- methods of preparing daridorexant by specific reaction sequences,
- making key intermediates used in the final steps,
- purification or crystallization steps that improve yield or form, and
- scalable manufacturing conditions.
If you share the WO number you already have (or the assignee/inventor), I can help you confirm whether it’s truly a process synthesis patent versus a formulation/dosage, polymorph, or medical-use patent.
Can biosynthesis/patent “WO” documents be different from the marketing authorization?
Yes. A drug can have multiple patent families:
- one around the active compound,
- one around specific manufacturing routes (process patents),
- one around formulations or dosing,
- and sometimes around specific uses.
So a daridorexant “process synthesis” WO document is typically not the same thing as the earliest compound-protection WO family.
If you want, I can identify the WO number(s)
Reply with any one of the following, and I’ll narrow it to the exact WO publication(s):
- the assignee/company name you think it’s from, or
- the WO number you already partially found (even if incomplete), or
- the intermediate name or reaction step you care about.
