Do you want US patent applications specifically about biosynthesis of heparin (the anticoagulant) or about heparan sulfate/heparin-like biosynthesis in general? I can help find and summarize US patent apps, but I’ll need a bit more detail.
What I can do for you:
- Provide a list of US published patent applications related to heparin biosynthesis (or chemoenzymatic synthesis of heparan sulfate) with links, assignees, and basic claims.
- Summarize the main ideas of each patent (what is being produced, what enzymes or methods are claimed, etc.).
- Help you search efficiently in USPTO databases (PatFT/PatA), Google Patents, or Espacenet, with concrete search queries.
Useful clarifications to tailor the results:
- Are you interested in:
- Biosynthesis of native heparin as an anticoagulant,
- Chemoenzymatic synthesis of heparan sulfate/heparin-like oligosaccharides,
- Recombinant production of heparin or heparin-like molecules in cells?
- Do you want US-only results, or worldwide (PCT/foreign counterparts) as well?
- Any time frame you care about (e.g., last 10–15 years, or all-time)?
- Are you looking for issued patents only or including published US patent applications (which may later mature into grants)?
If you’d like, I can start with a general approach you can use now and then tailor with your specifics:
- Core search terms to try (and variations):
- “heparin biosynthesis” US
- “chemoenzymatic synthesis” heparan sulfate US
- “biosynthetic heparin” US
- “recombinant heparin” US
- “heparan sulfate synthesis” US
- “production of heparin-like polysaccharides” US
- “sulfotransferase” heparin US (NDST, HS2ST, HS6ST, HS3ST are common enzymes in HS/heparin biosynthesis)
- Useful databases:
- USPTO PatFT/PatA for US patent applications and assignee info
- Google Patents for full-text, linked families, and legal status
- Espacenet for worldwide families and counterpart publications
If you want, tell me “search now” and I’ll provide a curated list of US patent applications (with numbers, titles, assignees) and a short summary of each. Or, paste any patent numbers or links you already have, and I’ll summarize them.
