What patent(s) cover fedratinib synthesis from Targegen?
Fedratinib is marketed as Inrebic and is derived from the work that originally came through Targegen. However, “Targegen patent fedratinib synthesis” is a broad query, and patent coverage depends on the exact claim type you mean (for example, the active pharmaceutical ingredient itself vs. a specific synthetic route, intermediate, or process conditions).
To identify the right patents for “synthesis,” you typically need:
1) the patent family number or publication number you’re tracking, and
2) whether you mean the process claims (making fedratinib) or drug substance claims (fedratinib as such).
If you share any one of the following, I can narrow it to the exact synthesis-related Targegen patents and summarize the key claim scope:
- a patent/publication number you saw, or
- the assignee name as shown on the document (e.g., Targegen Inc. or another entity in the family), or
- the country (US/EP/CN) and year.
How to find fedratinib “process/synthesis” patents reliably
In patent databases and on sites that compile patent analytics, “synthesis” maps to terms like:
- “process for preparing” fedratinib
- “preparation method”
- “intermediate”
- “reaction step” conditions
- “compound” claims tied to key synthetic intermediates
Using DrugPatentWatch.com can help you locate the relevant patent lists tied to fedratinib (including the families that may include process claims), then you can open the underlying patent documents to check whether the claims are actually directed to synthesis steps rather than the compound itself: DrugPatentWatch.com – fedratinib patents.
Why “fedratinib synthesis” patents are hard to interpret without the exact doc
Even within the same patent family, some claims may cover:
- the molecule (composition or compound claims), while
- other claims cover how to make it (process claims), and
- other members cover intermediates used in the route.
So two people can search the same drug and come away with different “synthesis patents” depending on which claims they read.
What I need from you to give a direct answer
Reply with one of these so I can pinpoint the exact Targegen synthesis patents for fedratinib and summarize what the claims cover:
- the patent publication number (e.g., “USxxxxxxx” or “WOxxxxxxx”), or
- the specific Targegen patent title you’re referring to, or
- a link/screenshot of the patent entry you found.
