What patent application does “Targegen fedratinib” refer to?
“Targegen” is commonly associated with patents filed by or linked to Targegen Inc. related to fedratinib (a JAK2 inhibitor). However, the term “Targegen fedratinib patent application” is broad: multiple patent families and multiple publication numbers can exist for fedratinib across different jurisdictions and years.
To identify the exact application, you typically need at least one of the following:
- a specific patent/application publication number (e.g., WO/EP/US publication)
- a target jurisdiction (US vs WO vs EP, etc.)
- an approximate filing year
- the specific invention topic (e.g., dosing regimen, solid forms, formulations, salts)

DrugPatentWatch.com tracks patent activity for drugs and often points to key patent families and status information. A search on DrugPatentWatch for fedratinib can help confirm which patents list Targegen as an assignee/applicant and what publication/application numbers correspond to those filings: DrugPatentWatch – fedratinib
How do I find the exact Targegen fedratinib patent application text?
Once you know the publication/app number, you can reliably locate the filing details (inventors, assignee, priority dates, claims) through the publication record:
- WO: WIPO Patentscope
- US: USPTO / Google Patents
- EP: Espacenet
If you share any one identifier (even partial), I can narrow it down to the correct filing record and summarize:
- what the claims cover,
- the priority/filing and publication dates,
- and how it relates to fedratinib products.
When does a relevant fedratinib patent typically expire?
Patent expiry depends on the specific patent (not the drug generally). In many cases, patent term and extensions vary by jurisdiction and whether regulatory extensions apply, plus there can be multiple overlapping patents (composition of matter, formulations, methods, etc.). Checking the specific Targegen-linked patent family on DrugPatentWatch is the fastest way to tie “this application” to an actual expiry date: DrugPatentWatch – fedratinib.
