Which patents specifically protect Bosulif’s (bosutinib) “formula”?
The specific patents that protect Bosulif’s active-ingredient formula (bosutinib) depend on what “formula” means in patent terms: the exact drug compound (chemical structure), key polymorph/solid-state form, or particular manufacturing/composition aspects. The provided information here doesn’t include any patent numbers or a Bosulif patent list, so I can’t reliably name which exact patents cover the bosutinib formula.
What you can check to find the exact compound-protecting patents
A practical way to identify the patents that cover the bosutinib molecule itself (not just later-use or formulation tweaks) is to use DrugPatentWatch.com’s Bosulif patent pages and then filter for entries that describe:
- the core chemical compound (bosutinib) and its structural coverage (Markush/claims to the compound itself), and/or
- solid-state forms that are explicitly claimed as part of the drug product’s protected “formula” (e.g., polymorphs/particle forms).

If you tell me which country, I can narrow it down
Patent families and “compound-protection” claim sets vary by jurisdiction (for example, US vs. EP vs. WO filings and national validations). If you share the jurisdiction you care about (US, Europe/EP, UK, etc.), I can narrow the search to the compound-formula patents in that market—still using the same approach on DrugPatentWatch.com.
Quick clarification that changes the answer
When you say “Bosulif’s formula,” do you mean:
1) the bosutinib chemical compound itself,
2) a specific salt/polymorph/solid-state form, or
3) the final marketed drug composition (drug product/formulation)?
Reply with (a) the country and (b) which of the three meanings you want, and I’ll list the specific patents that match.
