If you’re looking for US patent applications about producing histamine with microorganisms, here’s how to find them on Google Patents and what to look for.
How to search Google Patents (US-focused)
- Go to patents.google.com
- Try broad and then refined queries:
- "histamine production" microorganism
- "histamine production" bacteria
- histidine decarboxylase AND microorganism
- "biocatalytic production of histamine" OR "biosynthesis of histamine"
- "engineered microorganism" histamine production
- Use exact-phrase searches for better results:
- "histamine production" "microorganism"
- "histidine decarboxylase" patent
- Filter to US:
- In the left filters, set Country/Region to United States
- You can also filter by Patent status: Applications (A1, A9, etc.) to see US patent applications
- Optional refinements:
- After results load, filter by Assignee if you’re looking for corporate filings
- Search within results for specific organisms (e.g., Lactobacillus, Enterococcus) or enzymes (histidine decarboxylase)
- How to interpret results:
- Look for US publications with formats like US 201X/XXXXXX A1 (US application publications)
- Check the “Assignee” or inventor to gauge who filed
- Read the claims to see if the patent covers production of histamine by a microorganism, the specific microorganism, pathway engineering, or fermentation conditions
- Note the status in “Legal Events” to see if it’s pending, granted, or abandoned
Example search strings to start
- "histamine production" microorganism
- "histamine production" bacteria
- histidine decarboxylase microorganism
- "engineered microorganism" histamine production
- "biosynthesis of histamine" patent
What to look for in results
- Claim scope: Is the invention limited to a particular organism, a class of organisms, or any microorganism capable of histamine production?
- Method: Is histamine produced via fermentation, enzymatic decarboxylation, or a whole-pathway engineering approach?
- Regulatory/assurance notes: Some histamine-related processes touch on food safety (biogenic amines); note any regulatory considerations mentioned.
- Status: If it’s an application (A1/A9), it may or may not have issued as a patent; check the legal status tab.
If you’d like, I can help interpret specific US patents or applications you find. Paste the titles/links or share the publication numbers (e.g., US 2019/0123456 A1), and I’ll summarize the claims, scope, and potential relevance. If you want me to perform a targeted scan, tell me any particular organism types or companies you’re interested in.
