What patents cover vinblastine and vindoline biosynthesis on Google Patents?
I can’t directly look up Google Patents in real time from here, and you didn’t include any patent numbers or assignees. If you share a link to a Google Patents result page (or paste the patent titles/assignees you’re seeing), I can help you identify the specific patents that relate to vinblastine/vindoline biosynthesis and summarize what each one claims.
In the meantime, here’s how to narrow Google Patents to the right “biosynthesis” filings for vinblastine/vindoline.
How to search Google Patents effectively for vinblastine/vindoline biosynthesis
Use query patterns that include both the compound names and gene/enzymes/taxane pathway terms:
- Basic compound-focused terms:
- vinblastine biosynthesis
- vindoline biosynthesis
- vinblastine vindoline biosynthetic pathway
- Add pathway and enzymes (these often appear in filings that engineer microbes or plants):
- tabersonine AND vindoline
- O-acetylserotonin (or serotonin) AND vindoline
- deacetylvindoline AND vindoline
- dioxygenase AND vindoline (or similar enzyme terms)
- Add “platform” language that correlates with biosynthetic engineering:
- engineered OR recombinant OR transgenic
- microorganism OR yeast OR fungi OR bacteria
- plant cell culture OR plant cell OR hairy root
- Use assignee or inventor filters once you know who owns the key work:
- Example filter approach: add assignee: (company name) or just include the assignee in the search box.
If you tell me the company names you suspect (for example, major plant-pathway engineering groups), I can suggest tighter boolean queries tailored to them.
What to look for in a patent if it actually claims “biosynthesis”
On Google Patents, biosynthesis-related patents typically claim at least one of the following:
- Engineered cells or organisms (microbes/yeast/bacteria/plants) that produce taxane intermediates or vinblastine/vindoline.
- Specific enzymes and genetic constructs used to convert intermediates toward vindoline and downstream assembly.
- Methods of producing the intermediates (fermentation or culture conditions, feeding strategies).
- Pathway “module” claims (e.g., producing vindoline via a reconstructed subpathway).
A patent that mentions vinblastine or vindoline only in background or as an extraction target is less likely to be about biosynthesis.
Are vinblastine/vindoline biosynthesis patents usually about microbes or plants?
Most “biosynthesis” patent families in this space tend to fall into two buckets:
- Engineered microbial production of taxane intermediates (often yeast or other platforms), then conversion toward vindoline and/or vinblastine.
- Engineered plant systems (transgenic plants/cell culture) that produce intermediates and sometimes complete pathway steps.
The exact claims determine which bucket a given patent belongs to. If you paste a few candidate patent links, I can classify them quickly.
How long do biosynthesis patents stay active (and how can you tell on Google Patents)?
For US filings, the key fields on Google Patents are usually:
- “Status” / “Legal events”
- “Application” and “Publication” dates
- “Expiration date” (when shown)
- If it’s based on older priority dates, expiry may relate to those.
If you provide the jurisdictions (US/EP/CN) you care about, I can point you to what fields matter most.
If you’re trying to find the “core” vinblastine/vindoline pathway patents, what keywords matter most?
For vindoline, searches often work best when you include intermediate names rather than only “vindoline/vinblastine.” Many filings mention specific steps like conversions involving deacetylation/acetylation and intermediate rearrangements tied to vindoline formation.
Share any of these from your search results and I’ll translate them into targeted next searches:
- publication number(s)
- assignee name(s)
- intermediate compound names you see in titles/abstracts
- any enzyme names mentioned
Quick next step
Send either:
1) the Google Patents URL(s) you found, or
2) the top 5–10 result titles/assignees you’re seeing,
and tell me whether you want:
- the “most relevant” patents only, or
- everything that mentions biosynthesis (even partial pathway steps).
Then I’ll map which patents specifically cover vinblastine/vindoline biosynthesis and what each claims.
