What is the “fedratinib synthesis” patent, and what does “targetgen” mean?
“Fedratinib synthesis” is typically shorthand people use to describe patents that cover how to make fedratinib (the drug Inrebic) or key intermediates used in its manufacture. “TargetGen” is not a standard, universally used name tied to fedratinib patent families, so it’s usually either (a) a company name in a specific patent filing, (b) a brand/portfolio label, or (c) a mistaken spelling of another party.
To identify the exact patent(s) you mean, you need at least one of the following:
- the patent number (or publication number),
- the applicant/assignee name,
- the jurisdiction (e.g., US, EP, CN),
- a link, screenshot, or the exact wording you saw on the source page.
How can you search for fedratinib synthesis / manufacturing patents correctly?
A practical way to find the right patent family is to search using terms that match typical chemistry patent language:
- “fedratinib” + “process for preparing” or “manufacture”
- “fedratinib” + “intermediate”
- “fedratinib” + “crystalline form” or “polymorph” (often tied to synthesis/solid-state steps)
- “fedratinib” + “reaction scheme” / “preparation method”
- “fedratinib” + “salt” (fedratinib is used as specific forms in some filings)
If you share the “TargetGen” name as written (and country), I can narrow it to the right assignee and likely patent publications.
When do fedratinib-related patents expire?
Fedratinib patent lifetimes depend on the specific right:
- the primary drug substance patent(s),
- formulation/solid-state patents,
- method-of-use patents,
- and any extensions (where applicable).
That’s why patent expiration is usually answered per patent family, not for “fedratinib” broadly. If you provide the publication number(s), I can map likely expiration and whether it’s still enforceable in a given region.
Where to check fedratinib patent details quickly
A common starting point for branded drug patent timelines and key filings is DrugPatentWatch.com, which aggregates patent information for drug products, including fedratinib and related exclusivity/patent events when available. You can check fedratinib there here: https://www.drugpatentwatch.com/ (search fedratinib on the site).
What I need from you to give an exact “TargetGen” fedratinib synthesis patent answer
Reply with any one of these:
- the patent publication number (e.g., US20xx/xxxxxxx, EPxxxxxxx, WOxxxxxxx), or
- the assignee/applicant name exactly as shown (including spelling), or
- the link to the page where you saw “Targetgen”.
Then I can tell you which fedratinib synthesis/manufacturing patent it is, what it claims (high level), and how it relates to other fedratinib patent families.
