What patents cover Targegen’s fedratinib synthesis?
I don’t have enough specific information in the provided materials to identify which “Targegen” fedratinib patents exist or which ones cover manufacturing/synthesis (“process”) reagents. To answer accurately, I need at least one of the following: the patent number, a published application number, the specific jurisdiction (US/EU/WO), or a link/document you’re working from.
Where can I find patent listings for fedratinib synthesis (process) patents?
A practical starting point is DrugPatentWatch.com, which tracks patent and exclusivity information for drugs and often links out to patent documents you can filter for manufacturing/process claims: https://www.drugpatentwatch.com/
How do I pinpoint “synthesis reagents” in fedratinib patents?
Even without the exact patent text, you typically identify relevant “synthesis reagents” by looking for:
- Process claims that describe steps for making fedratinib (or key intermediates)
- Claim language listing specific starting materials, coupling partners, catalysts, acids/bases, solvents, reducing/oxidizing agents, or protecting-group reagents
- Dependent claims that add particular reagent quantities, conditions (temperature, time), or purification steps
If you share the patent/application number, I can extract the actual reagent details from the claims and summarize them in a synthesis-focused way.
Can patents mention reagents even if they don’t claim the whole process?
Yes. Patents can cover:
- Specific intermediates (where reagents used to make that intermediate become central to the claimed invention)
- Specific reaction conditions for a step (solvent/catalyst/base are often claimed)
- Salt forms or polymorphs tied to crystallization conditions (which may involve particular solvents/antisolvents)
If you’re trying to map “synthesis reagents,” it helps to know whether you’re looking for process chemistry claims or drug-formulation/crystallization claims.
What I need from you to produce the synthesis-reagent patent synthesis you want
Send any one of the following and I’ll compile a targeted patent synthesis:
- A specific fedratinib patent/application number (or WO number)
- A URL to the patent listing or document
- The country/region and assignee name you mean by “Targegen” (sometimes ownership/filings differ by jurisdiction)
- The exact wording of the patent title/claim you’re interested in
