Patents google com patent us vinblastine vindoline?

Do you want US patent numbers and a summary for patents covering vinblastine and vindoline? I can help guide you to them on Google Patents, but I can’t pull live results without a web browse request. If you’d like, I can summarize any specific patent you provide or help you search.

Here’s how to find them quickly on patents.google.com:
- Go to patents.google.com
- In the search bar, try:
- "vinblastine vindoline"
- "vindoline vinblastine"
- "Catharanthus roseus vinblastine"
- "vindoline synthesis patent" or "vinblastine synthesis patent"
- "vinblastine dimerization catharanthine vindoline patent" (since vinblastine is formed by coupling vindoline with catharanthine)
- Filter results to the United States (US) and sort by oldest to see early isolation/production patents or by newest for newer biosynthesis/production methods.
- If you want patents that mention both compounds specifically, use exact-phrase searches like: "vinblastine" "vindoline".
- You can also search for related topics like “biosynthesis,” “plant cell culture,” or “semi-synthesis” to catch patents on production methods.

If you want, tell me:
- A rough date range (e.g., 1950s–1990s, or 2000s–present)
- Assignee you care about (e.g., major pharma companies historically involved with vinca alkaloids)
- Whether you want old isolation patents or newer biosynthetic/semi-synthetic process patents

I can then summarize the key US patents and their claims for you, or help you interpret the landscape. If you already have a Google Patents link, paste it and I’ll summarize it.
