I can help you find and interpret US patent application claims about histamine biosynthesis production on Google Patents, but I can’t perform a live web search from here. If you share a specific publication number or link, I can summarize the claims for you. In the meantime, here’s how you can find and inspect them yourself:
How to search on Google Patents
- Go to patents.google.com
- In the search box, try terms like:
- "histamine biosynthesis production"
- "production of histamine by fermentation"
- "histidine decarboxylase histamine production"
- "histamine biosynthesis microorganism US"
- After you get results, filter to US documents:
- Use the country/status filters (select US and “Application” or “Patents”) to focus on US patent applications.
- Sort by date if you want the latest filings.
Reading the claims
- Click a result to open the patent page.
- Go to the “Claims” tab to see the legal scope. The first claim is the independent claim; it defines the core invention.
- You can click “Claims” again to see each dependent claim and how they narrow or add features.
- For full text, click “PDF” (or “View PDF”) to see the published application as filed, which helps with exact wording.
- Use the “Family” section to check related US grants or foreign filings.
What you’re likely to see in such claims
- Independent claim structure often covers a method or a host organism engineered to produce histamine. Common elements include:
- A microorganism (e.g., a bacterium) that expresses histidine decarboxylase (hdc) or equivalent activity.
- Growth conditions or fermentation parameters enabling histamine production.
- Optional genetic modifications that increase yield, rate, or titer of histamine.
- Dependent claims typically specify:
- Specific genes, promoters, or regulatory elements used.
- Specific host strains or chassis organisms.
- Particular media, pH, temperature, or fermentation modes.
- Purification or recovery steps for histamine.
Tips to evaluate claims
- Independent claim focus: look at what the claim requires to be “infringing.” Are the steps or features broad or narrowly defined?
- Enablement: do the examples or description give enough detail to practice the invention?
- Scope vs. novelty: how the claim reads against prior art you’re aware of (existing methods of histamine production, hdс variants, etc.).
- Legal status: check if the US application matured into a grant (US patent) or if it was abandoned; look for family members in other jurisdictions for broader protection.
If you want, paste or share:
- A publication number (e.g., US 2019/0123456 A1) or a link, or
- The exact term you’re most interested in (e.g., “host organism with histidine decarboxylase for histamine production”),
and I’ll summarize the independent claim(s) and explain the scope, plus point out any notable limitations or ambiguities. If you don’t have a number yet, tell me which angle you care about (process vs. organism vs. purification) and I’ll help you narrow search terms.
