What does Google Patents show for US patent applications on vinblastine/vindoline biosynthesis?
Google Patents can be used to find US patent applications that mention “vinblastine,” “vindoline,” and biosynthesis-related terms (for example, pathway enzymes, engineered plants, microbial production, or extraction/bioconversion routes). Search terms that usually work include combinations like:
- “vinblastine vindoline biosynthesis”
- “vinblastine vindoline pathway”
- “indole alkaloid” AND “vinblastine”
- “Catharanthus” (the Madagascar periwinkle genus) AND “vindoline”
- “engineered” AND (“vinblastine” OR “vindoline”)
To get precise results on Google Patents, filter by:
- Jurisdiction: United States (US)
- Document type: Application (US application) vs granted patents (US patent)
- Dates: set a range based on when you expect filings (for example, recent years if you’re focused on microbial/bioprocess approaches)
Which kinds of US filings are most likely to cover vinblastine/vindoline biosynthesis?
US patent application themes you’ll commonly see tied to vinblastine and vindoline (and closely related indole alkaloid intermediates) include:
- Engineered production platforms (engineered microbes or engineered plant systems) that produce vindoline or upstream intermediates used to form vinblastine.
- Methods to increase supply of pathway precursors (for example, boosting expression of pathway enzymes that control flux to vindoline).
- Enzyme/tool claims around specific biosynthetic steps (often multiple genes/enzymes across the pathway).
- Processing steps that convert intermediates into vinblastine under controlled conditions.
If your goal is “biosynthesis” specifically, you’ll typically get more relevant documents by including “biosynthetic,” “pathway,” “engineered,” “recombinant,” “in vivo,” “in planta,” “bioconversion,” or “microbial production” in the Google Patents query.
Are there specific key terms that separate “vinblastine” claims from “vindoline” claims?
Yes. Vindoline is often claimed as:
- A target intermediate being produced/accumulated, or
- A feedstock for downstream conversion toward vinblastine.
Vinblastine-focused claims more often include:
- The final production of vinblastine (or steps closely adjacent to final coupling/conversion).
- End-to-end production or conversion workflows.
So, if you search only “vinblastine,” you can miss filings that concentrate on vindoline biosynthesis/accumulation, and vice versa. Using both terms together (vinblastine AND vindoline) usually helps capture both categories, but it can also filter out documents that only mention one intermediate explicitly.
What should you check in the Google Patents record to confirm it’s really about biosynthesis?
When you open a candidate Google Patents page for a US application, check for indicators such as:
- The title/abstract mentioning biosynthesis, biosynthetic pathway, engineered production, or bioconversion rather than only extraction or chemical synthesis.
- Claims that mention recombinant enzymes/genes, pathway regulation, hosts (microbes/plants), or production in a biological system.
- References to indole alkaloid pathway enzymes (typical of vindoline/vinblastine research) rather than purely chemical coupling steps.
How can you narrow results to “US patent application” (not granted patents) on Google Patents?
In Google Patents:
- Use the “Type” filter and choose “Patent application” (wording can vary in the UI).
- Add a US application number pattern if you already have candidates (for example, searches that include “US” plus the application publication format).
- Use the “Status” or “Publication type” controls to avoid mixing granted patents with applications.
What if you’re seeing too many irrelevant indole alkaloid results?
Try adding one or more constraints:
- Add “Catharanthus” when appropriate (vindoline pathway work frequently references this organism).
- Add “indole alkaloid pathway” or “monoterpene indole alkaloid.”
- Add production-platform terms like “microbial,” “yeast,” “plant,” “cell culture,” or “in planta.”
- Exclude terms by adding NOT clauses (for example, NOT “chemical synthesis” if the results are irrelevant to biosynthesis).
Can you share what you’re looking for, and I can point you to the right Google Patents queries?
If you tell me either (a) a year range, (b) whether you care about engineered microbes vs engineered plants, or (c) whether you want applications that target vindoline specifically or vinblastine as the final product, I can suggest tighter Google Patents search strings that are more likely to surface the exact US applications you want.
