Google patents heparin biosynthesis us application?

I can help, but I need one quick clarification because your query is a bit ambiguous.

When you say “heparin biosynthesis us application,” do you mean:

1. A US (United States) patent application related to heparin biosynthesis, or
2. How to find Google Patents results specifically for heparin biosynthesis in the US, or
3. A specific patent you saw (and want the details/summary)?

If you want to search on Google Patents (US applications)

Try these searches:

• Heparin biosynthesis (US)
  • heparin biosynthesis site:patents.google.com US
• Heparan/heparin biosynthetic pathway
  • heparan sulfate biosynthesis heparin US patent
• Enzymes in heparin/heparan sulfate biosynthesis
  • heparin biosynthesis N-deacetylase US patent application
• MSC/engineering/biological production of heparin
  • bioengineered heparin biosynthesis US patent application

Then use Google Patents filters:

• Country/Region: United States (US)
• Document type: Patent application (or “Applications”)

If you want me to identify the exact patent

Paste either:

• the Google Patents link, or
• the patent/application number, or
• the title/assignee you saw.

And tell me what you want from it (e.g., inventor, claims summary, technology overview, or status).
