What patent for dasatinib did Bristol Myers Squibb file around 2000?
Dasatinib (Sprycel) is associated with Bristol-Myers Squibb’s early compound and formulation patent filings from the late 1990s and early 2000s. However, the exact patent number and its “WO” (PCT publication) depends on the specific WO document you mean, because the same drug family can have multiple related patent filings and publication numbers.
If you share the WO publication number (it will look like “WO YYYY/######”), or the country/patent number you’re looking at, I can pinpoint the filing and explain what it covers (compound, salt, formulation, or method of use).
How long do dasatinib patents filed around 2000 typically last?
For most pharmaceutical patents filed around that time, the core patent term is generally designed to run toward roughly 20 years from the earliest effective filing date, subject to local patent-law adjustments and any patent-term extensions or delays. Specific expiration timing for dasatinib will vary by jurisdiction (US, EP, UK, etc.) and by which WO family member is being enforced.
What does “WO” mean here?
“WO” refers to a PCT (Patent Cooperation Treaty) publication. A single PCT application can later enter national or regional phases (like US, EP, etc.), producing different national patents with different grant/expiration dates. So “dasatinib patent 2000 WO” usually means a PCT publication in 2000 related to dasatinib.

If you tell me the WO number, I can answer precisely
Reply with either:
1) the full WO publication number (example format: WO 2000/123456), or
2) the jurisdiction you care about (US, EP, UK, etc.), or
3) the patent number you saw in a listing,
and I’ll map it to what it covers and what the likely expiration timeline is for that particular WO family member.
