What vinblastine/vindoline biosynthesis patents exist in the US?
Google Patents can be used to search for US patent applications that cover the biosynthesis of vinblastine and/or vindoline (often linked to Catharanthus roseus pathways). The key issue for US relevance is finding records where the publication includes a “US” jurisdiction, typically in the format “US20xx/…” or “US …” and where the assignee/inventor names match the biosynthesis (not extraction, purification, or formulation) angle.
In practice, these filings often cluster around:
- Methods for producing vindoline (or directly producing vinblastine) using engineered plants, cell culture, or microbial/enzymatic pathways.
- Genes/enzymes involved in the pathway and constructs (e.g., enzymes that convert pathway intermediates toward vindoline/related alkaloids).
- Bioreactor or cell-culture production systems that claim improved yields or specific intermediates.
To confirm the exact US application(s), the most direct approach is to run a targeted Google Patents query that includes both the drug terms and biosynthesis terms (examples below).
How to search Google Patents for “vinblastine vindoline biosynthesis” US applications
Use search operators to narrow to US filings and biosynthesis claims:
- Basic US-focused query (start here):
- vinblastine vindoline biosynthesis country:US
- If you want engineered production rather than general methods:
- vinblastine vindoline engineered biosynthesis country:US
- If you want claims involving genes/enzymes/cells:
- vinblastine vindoline gene enzyme biosynthesis country:US
- If the application might use “catharanthine”/“catharanthine-to-vindoline” pathway wording:
- vindoline catharanthine biosynthesis country:US
- If you want specific pathway-operator terms:
- vindoline pathway enzyme construct country:US
Then filter results by “Assignee,” “Inventor,” and “Current assignee” to see which organizations are repeatedly filing in this space.
Are there known vinblastine/vindoline pathway companies filing in the US?
Yes, companies and academic groups often pursue US filings for engineered biosynthesis of indole alkaloids, including vinblastine/vindoline-related pathways. However, the exact “which application(s)” depends on the specific scope of your search (genes vs. production method vs. engineered host vs. intermediate production).
If you share any of the following, I can help you pinpoint the most likely matching Google Patents records more accurately:
- Any inventor name or assignee name you saw
- A publication number (even partial)
- The year range (e.g., 2015–2024)
- Whether you mean “vindoline” specifically, or “vinblastine produced via vindoline pathway”
Does this relate to “patents for vinblastine production” or to “drug products”?
This matters because many “vinblastine” patents in the US are about:
- drug manufacturing/formulation,
- purification/extraction from plant material,
- dosing or combination therapy,
not biosynthesis itself.
Your wording “biosynthesis patent application” points to the earlier, upstream IP: engineered biosynthetic pathways, genes, and production hosts. In a Google Patents search, adding “biosynthesis,” “pathway,” “engineered,” “cell,” “microorganism,” “plant,” or “enzyme” is the fastest way to avoid extraction/formulation results.
Where does DrugPatentWatch.com fit in?
DrugPatentWatch.com is helpful for mapping drug-related patent landscapes (especially when you’re trying to relate patents to exclusivity or commercial timelines). For biosynthesis-specific patent applications, Google Patents is usually the best primary tool to identify the exact US filings. If you’re trying to tie biosynthesis patents to an eventual branded/copyrighted product timeline, DrugPatentWatch.com can help find related patent/patent-family context.
You can start here with Vinblastine-related coverage on DrugPatentWatch.com:

(If you tell me the exact drug/product name page you’re looking at, I can suggest how to cross-check it against the Google Patents records.)
Quick next step
Send one of these and I’ll narrow it to the specific US application(s) you’re asking about:
1) the assignee/company name, or
2) an inventor name, or
3) a Google Patents link or publication number, or
4) the year range.
