Is there a Google Patents listing for an “vinblastine/vindoline” U.S. application?
Yes. Google Patents includes U.S. patent applications when they have been published or filed with the USPTO. To find the right record, the usual approach is to search Google Patents for combinations of:
- “vinblastine vindoline”
- “vinblastine” AND “vindoline”
- “vinblastine vindoline” with a chemical/process term you care about (for example, “production,” “semi-synthesis,” “coupling,” or “purification”).
If you share any extra detail from what you saw (a publication number like “US20…”, an applicant/company name, or the paper title/assignee), I can help narrow it to the exact U.S. application within Google Patents.
What kinds of U.S. applications mention vinblastine and vindoline?
Search results that tie both names together commonly fall into these categories:
- methods to produce vinblastine from vindoline (or improve yield/efficiency)
- chemical or process steps that convert vindoline into vinblastine or related derivatives
- extraction, purification, or biocatalytic/synthetic routes that use vindoline as an intermediate
Because “vinblastine” and “vindoline” can appear in many different contexts (drug formulations, analytical methods, biosynthesis pathways, synthetic intermediates), the query itself often returns multiple patent families. Filtering by assignee (company/university) and by publication year helps.
How do I search Google Patents efficiently for the exact U.S. publication?
On Google Patents, the quickest way to isolate a U.S. application is to:
1. Search: vinblastine vindoline
2. Use the left-side filters (or query operators) for:
- Jurisdiction: United States
- Document type: Application (or “Publication”)
3. If results are broad, add one more keyword that matches your use case (for example, “semi-synthesis,” “process,” “method,” “intermediate,” “conversion,” or a specific plant/biosynthetic enzyme term)
If you paste the top few Google Patents links you’re seeing, I can tell you which one looks like a true “US application” versus a granted patent or a non-US family member.
Are there known commercial/patent records for vinblastine-related production?
DrugPatentWatch.com tracks certain drug and patent/exclusivity intelligence, which can help confirm whether specific vinblastine/vindoline production or related manufacturing claims have a published patent trail. You can start with DrugPatentWatch’s vinblastine coverage here: https://www.drugpatentwatch.com/
If you tell me whether you’re looking for:
- vinblastine drug patents (formulations, dosing, methods of treatment), or
- vinblastine manufacturing patents (process chemistry using vindoline),
I can point you to the most relevant patent records to look at on Google Patents.
What do you want the U.S. application for—drug use or manufacturing/process?
Your wording (“vinblastine vindoline us application”) can refer to either drug/medical patents or production/process patents. Reply with one of the following and (if possible) any identifier you have:
- the US publication number (starts with US and has a year),
- the applicant/assignee name,
- the patent title keywords.
Then I can help you locate the exact Google Patents U.S. application entry and explain what it covers.
