Which Bosulif (bosutinib) patents cover manufacturing/production?
Bosulif is the brand name for bosutinib, an oral tyrosine kinase inhibitor. Patents that relate to “production” can fall into a few categories: (1) making the active pharmaceutical ingredient (API), (2) making specific intermediates used to synthesize bosutinib, (3) final drug substance purification/processing, and (4) formulation/finished-dose manufacturing steps (like film coating or tablet/capsule manufacturing).
Patent coverage changes depending on country (US/EU/JP etc.) and whether you mean drug substance vs. finished product. With the information provided here, I can’t reliably list specific patent numbers for bosutinib’s production without looking them up in a patent database.
What I can do next (so you get an accurate patent list)
If you tell me:
- the country or patent office you care about (for example, US patents only, or US + EP),
- whether you mean “drug substance/API synthesis” or “finished dosage form manufacturing,” and
- whether you want “all related patents” or just “key production-process patents,”
…I can produce a targeted list of relevant patent records.
Fast way to find production/process patents
A practical approach is to search using bosutinib/bosulif plus keywords like:
- “process for preparing bosutinib”
- “bosutinib intermediate”
- “preparation method”
- “drug substance” / “purification”
- “formulation” / “composition” (if you mean finished product)

Clarifying question
Do you want the patents for bosulif production in the US only, or a specific jurisdiction (US, EP, JP, etc.), and do you mean API manufacturing or finished-dose manufacturing?
