What is WO2000062778A1 and how does it relate to dasatinib?
WO2000062778A1 is a patent publication code (WO = PCT publication). On Google Patents, it may show as a document that is either about dasatinib directly or about related kinase inhibitors and related chemistry/uses. The exact relationship (direct claims on dasatinib vs. broader prior art) depends on what the claims in that specific document cover.
How do I find it on Google Patents (and verify it’s about dasatinib)?
To check the exact connection to dasatinib on Google Patents:
1. Go to Google Patents and paste WO2000062778A1 into the search bar.
2. Open the result and use the “Claims” and “Description” sections to see whether “dasatinib” (or known synonym names) appears.
3. Check the “Assignee/Applicant” and “Inventor” fields to see whether they match organizations known for dasatinib filings.
Does the “A1” mean it’s a granted patent or just an application?
On PCT publications, A1 typically means it’s a published application document (not a granted patent). Google Patents will often show later statuses (if granted anywhere) under “Events” or related records.
Could this be a common confusion with other dasatinib patent numbers?
Yes. People often misread or mix up publication numbers (for example, transposed digits or different WO/PCT publication dates). Verifying the exact document on Google Patents using the full WO2000062778A1 string is the fastest way to avoid looking at the wrong patent.
How can I check whether it’s still relevant (patent term / exclusivity)?
Relevance depends on where it was filed and whether it matured into granted rights. On Google Patents, you can review:
- “Legal status” (active/expired)
- “Expiration date” (where available)
- Related family members (other jurisdictions)
If you paste the Google Patents link or the assignee, I can tell you what it covers
If you share the Google Patents URL you mean (or the assignee/inventor shown on that page), I can summarize:
- whether it explicitly claims dasatinib
- what the claimed technology is (compound, synthesis, formulation, method of use)
- whether it looks like a composition-of-matter vs. method/use claim (which affects how it impacts generic/biosimilar-style entry)
