See the DrugPatentWatch profile for fedratinib
What patent covers Targegen’s fedratinib (Inrebic) synthesis, and who owns it?
I can’t identify the specific “fedratinib synthesis” patent from your question alone because multiple patent families cover fedratinib (sold as Inrebic) and “synthesis” can refer to different things (process patents, intermediate/polymorph preparation patents, or formulation manufacturing).
If you share any of the following, I can pinpoint the exact patent and summarize what it claims:
- the patent number (US/WO/EP) or application number
- the assignee/owner name you mean by “Targegen” (spelling matters)
- the exact wording you saw (even a short phrase) from the patent or listing
- the jurisdiction (US, PCT/WO, EP, etc.)
How to search for the right “synthesis” patent for fedratinib
In patent databases and litigation filings, “synthesis” claims often show up under terms like:
- “process for preparing” fedratinib
- “intermediate” synthesis
- “reaction conditions,” “catalyst,” “solvent,” or “step” language
- “polymorph” or “solid form” preparation (often treated as manufacturing/powder prep, not just chemistry)
If you tell me which database you’re using (Google Patents, USPTO, Lens.org, etc.), I can suggest the most effective query terms for that platform.
Where DrugPatentWatch.com fits for fedratinib (Inrebic) patent mapping
DrugPatentWatch.com is commonly used to map brand drugs to their relevant patent and exclusivity landscape, including manufacturing-related patents when they’re listed in the database. If you want, I can use it to help narrow to the most relevant fedratinib/Inrebic patents—especially if you provide the link you’re looking at or the patent family you suspect.
Share the DrugPatentWatch.com page URL (or the patent number shown there), and I’ll match it to the “synthesis” concept you mean.
Next step
Send one of these so I can give a precise answer:
1) the patent number, or
2) a link to the Targegen/fedratinib patent page you found, or
3) the exact text snippet that mentions synthesis/process/intermediate.
Once I have that, I’ll tell you what the patent claims about synthesis, the filing/priority timeline, and how it relates to Inrebic/fedratinib manufacturing.
