What patent application(s) cover vindoline or vinblastine, and what does Google Patents show?
You’re likely looking for patent records that mention “vindoline” and/or “vinblastine” (often in the context of isolation, purification, semi-synthesis, or formulation). Google Patents search results depend heavily on how you query (for example: inventor, assignee, publication number, or keywords in the abstract/claims).
If you tell me any one of the following, I can narrow it down to the exact application(s):
- the patent publication number (starts with something like WO/US/EP… plus numbers), or
- the assignee/company name, or
- the exact wording you used in Google Patents (your query string), or
- the country you care about (US, WO, EP, etc.).
Are there US patent applications specifically about vinblastine/vindoline (as keywords or in the claims)?
Many vinblastine-related filings are not just “about vinblastine” as a product, but about methods such as:
- extracting or isolating vindoline/vinblastine from plant sources,
- converting vindoline derivatives into vinblastine/vinblastine analogs,
- improving yields/purity or scaling purification processes,
- formulations and delivery methods.
Those details are what usually determine whether a US application is truly relevant versus just referencing the compounds in the background.
How can I find the exact US application you mean (best Google Patents query patterns)?
On Google Patents, try queries that match how compounds appear in titles/claims:
- "vinblastine" assignee:<company>
- "vindoline" vinblastine (two keywords in the same record)
- vinblastine (isolation OR purification OR process)
- Limit by jurisdiction using filters (United States) once you see results.
If you paste the top results you’re seeing (titles or publication numbers), I can map them to the likely claim scope.
What about patents “vindoline vinblastine patent application us” from DrugPatentWatch.com?
DrugPatentWatch.com is useful when you’re trying to connect a specific patent or exclusivity listing to a marketed product or known rights holders. If you share the drug/brand name or the company you suspect holds the rights, I can check whether DrugPatentWatch has a relevant listing and link it.
Next step: send one detail so I can pinpoint the exact application
Reply with either:
- a US publication number you’ve seen, or
- the assignee/company name, or
- a screenshot/text of the Google Patents result(s).
Then I can tell you which Google Patents application it is, who filed it, what it claims (high level), and whether it looks like a primary patent (composition/method) or a secondary process/formulation patent.
