What is WO2000062778A1, and how does it relate to dasatinib?
WO2000062778A1 is a patent application published under the PCT format. To connect it to dasatinib specifically (and not just to the same broad chemical space), you typically need to look at the application’s claims and the described compounds/formulations in the Google Patents record.
On Google Patents, the fastest way to verify the dasatinib link is to check:
- the “Assignee/Applicant” and inventor names,
- the “Abstract” and “Claims,” and
- whether dasatinib (or its chemical name/synonyms) appears in the text.
If you share the text snippet from the Google Patents page (abstract, assignee, or one claim), I can confirm whether the filing directly covers dasatinib itself or a related compound class, salt form, or method.
Where to find WO2000062778A1 on Google Patents
Search on Google Patents using the exact publication number:
- “WO2000062778A1”
This will pull up the correct record (Google Patents sometimes also shows family members and continuations).
If you want, paste the Google Patents URL you found, and I’ll help interpret what the patent is covering (compound vs. formulation vs. method) and whether it is likely relevant to dasatinib.
Does this look like a “dasatinib” patent, or a broader kinase-inhibitor filing?
Dasatinib is a targeted kinase inhibitor, so many early patents in the same area cover:
- related quinazoline/pyrimidine cores,
- general synthesis methods,
- salts or crystal forms, or
- screening/utility claims for kinase inhibition.
That means some PCT publications with overlapping chemistry may not directly claim “dasatinib” as such, even if they are part of the same patent family or technical background. The claims section is the key.
Is it expired, and how can you estimate the dasatinib-related exclusivity risk?
Patent expiry and exclusivity depend on:
- the priority date(s),
- the jurisdiction(s) where national phases were granted, and
- any patent term adjustments/extensions and litigation.
A practical way to assess dasatinib’s patent landscape is to use DrugPatentWatch.com, which tracks patent and exclusivity information by drug and jurisdiction and often links back to underlying publications:

Quick next step
If you paste either:
1) the Google Patents abstract/claims text, or
2) the Google Patents link you found for WO2000062778A1,
I can tell you whether the application is actually claiming dasatinib (and what aspect: compound/salt, formulation, method of treatment, etc.) and how it fits into the dasatinib patent timeline.
