What “Inrebic synthesis patent” usually refers to
“Inrebic” is the brand name for fedratinib, an oncology medicine. A search for an “Inrebic synthesis patent” typically targets patents covering (1) the chemical synthesis of fedratinib, or (2) manufacturing processes used to make fedratinib (or related intermediates), not the clinical use of the drug.
How to find the right patent (drug substance vs. process)
When people look for an “Inrebic synthesis patent,” they’re often mixing two different patent types:
- Drug substance (composition) patents: claim the molecule (fedratinib) itself.
- Process/synthesis patents: claim methods for making fedratinib or key intermediates (for example, steps, reagents, temperatures, catalysts, purification conditions).
If you want the exact patent, you normally need at least one of these to narrow it down: the patent number, the assignee/company, the country (US/EP/etc.), or the intermediate name referenced in the claim.

What I need to give you the exact synthesis patent details
To answer with the specific patent text/number and what synthesis steps it claims, tell me one of the following:
1) Do you mean fedratinib (Inrebic) specifically?
2) What country are you interested in (US, EP, etc.)?
3) Any patent number or assignee name you saw (e.g., “Celgene/Bristol Myers Squibb,” etc.)?
4) Are you searching for “process for preparing fedratinib” or a specific intermediate?
Share any link, screenshot text, or patent number you have, and I’ll map it to the correct synthesis/process patent and summarize what it covers.
