What patents cover fedratinib, and why “synthesis patent” searches come up
Patents related to fedratinib typically fall into two buckets people often search differently:
- Drug (or use) patents: cover the active ingredient itself and/or specific approved uses.
- Manufacturing (process/synthesis) patents: cover how the drug is made, including particular chemical steps, intermediates, or purification methods.
Because process patents can still matter even after a drug substance patent expires, searches for “fedratinib synthesis patent” usually aim to find whether any manufacturing/process protections remain in force, potentially affecting generic or biosimilar-style competition for small molecules (though fedratinib is a small molecule).
How to find the specific “fedratinib synthesis” (process) patent you mean
To identify the exact “target” fedratinib synthesis patent, you generally need at least one of the following:
- a patent number (best), or
- the assignee/company name (original developer or current patent owner), or
- a jurisdiction (US, EP, WO, etc.), or
- the intermediate/step description used in the claim (often in the abstract/title).
Without that, “synthesis patent” could refer to multiple different filings (different routes, different intermediates, different purification steps).
Where DrugPatentWatch helps (and what to look for)
DrugPatentWatch.com is a common starting point for tracking fedratinib-related patent coverage, because it compiles patent information and can help you filter for what’s tied to:
- the active ingredient vs.
- manufacturing/process filings vs.
- data/exclusivity events (depending on the country).
You can search directly on DrugPatentWatch for fedratinib and then review the patent entries for any that mention process, manufacture, preparation, or intermediates (the terms that usually signal “synthesis/process” scope).

Is there a single “target fedratinib patent” you can name from this question alone?
“Targetgen fedratinib patent” reads like it could mean one of these:
- you’re trying to find a patent owned by a party named Targetgen, or
- you’re searching for the target (i.e., which patent blocks entry) in the fedratinib patent landscape.
But with only the phrase “targetgen fedratinib patent,” there isn’t enough information to accurately identify a specific patent or confirm whether “Targetgen” is the relevant assignee in the fedratinib family.
What I need to pinpoint the exact patent
Reply with any one of the following, and I can help you zero in on the correct fedratinib synthesis/process patent and its coverage:
1) the country (US/EP/WO), or
2) the patent number, or
3) the assignee name you mean by “Targetgen” (full legal entity), or
4) a link (or screenshot text) from DrugPatentWatch or another patent listing.
