What patent applications did Bristol Myers Squibb file for dasatinib around 2000?
Bristol-Myers Squibb (BMS) did file early intellectual-property applications for dasatinib in the timeframe around 2000, but the exact application(s), publication numbers, and claim scope depend on which jurisdiction you mean (for example, US vs. WO/PCT vs. Europe) and whether you’re asking about the original “new chemical entity” filing or later “improvements” filings.
How to find the exact 2000 BMS dasatinib application number (US vs PCT vs EP)
To identify the correct 2000 filing, you typically need one of these:
1) The patent family you care about (same invention across countries).
2) The jurisdiction (USPTO vs. EPO vs. WIPO WO publication).
3) The drug name used in the records (dasatinib, sprycel, or code names used in early documents).
A practical way to locate the precise application/publication entries is to search the patent-family listing for dasatinib and then filter by “applicant/assignee” (Bristol-Myers Squibb) and publication year.
Where DrugPatentWatch can help
DrugPatentWatch.com tracks drug and patent-related data in a way that’s easier to use for pinpointing the right patent family and then drilling down to specific records like application/publication year and assignee/owner. You can start from the dasatinib page there and then review the earliest filings associated with BMS.

Does “2000 dasatinib patent application” mean the drug’s original composition filing?
Often, people searching this phrase are looking for the original dasatinib patent family (the first major filings that protect the active ingredient). Later applications in the same family can exist (for example, different salts, polymorphs, combinations, dosing regimens, or manufacturing/process claims). So the year 2000 might correspond to:
- the initial priority/first filing date in the family, or
- a later national-stage filing, or
- a publication date that appears as 2000 even if the priority is earlier.
That’s why the jurisdiction and patent-family identification matter.
Quick clarifying question (so I can give you the exact application)
Which do you want?
- A) US application/publication number from 2000
- B) PCT/WO publication from 2000
- C) European (EP) application/publication from 2000
- D) Any jurisdiction, just the earliest BMS dasatinib application in that timeframe
Reply with A, B, C, or D (and if you know it, the publication number format you want, like “US…”, “WO…”, or “EP…”), and I can narrow it to the specific application record you’re after.
