How do I search Google Patents for “histamine production” in the US?
Use the Google Patents search box with a focused query, then filter to US documents. Common query strings that match how “histamine production” is discussed in claims and descriptions include:
- "histamine production" AND (United States OR US)
- histamine production site:patents.google.com (browse results directly in Google Patents)
- ("histamine" AND (production OR produce OR producing)) AND (assay OR method OR process)
- histamine AND (biosynthesis OR decarboxylase OR histidine decarboxylase) AND (US OR "United States")
After you get results, narrow by:
- Document country: United States (US)
- Publication type: Patent application (if you specifically want applications)
- Date range (if you’re looking for newer filings)
- Keyword filters if available (e.g., claims vs full text)
Because histamine can be described with related terms (histidine decarboxylase, decarboxylation, HDC, histamine biosynthesis), you’ll often find more relevant US patent applications by searching with those terms even if they don’t include the exact phrase “histamine production.”
What related terms should I use besides “histamine production”?
Patent text may describe histamine generation indirectly. Searches that often work better than the exact phrase include combinations like:
- histidine decarboxylase (often abbreviated HDC)
- decarboxylation or decarboxylase
- histamine biosynthesis
- histamine release (sometimes used for food, immune, or mast-cell contexts)
- mast cell / H1 receptor (if the patent is about signaling rather than production)
If you only search the literal phrase “histamine production,” you can miss applications that describe the same pathway using different wording.
How can I find United States patent applications specifically (not granted patents)?
In Google Patents, “patent application” results are usually labeled by publication kind codes and categories. Practical approaches:
- Filter “US” as the country first.
- Then use the “Publication” date or type filters to include applications.
- Look for US publication numbers (commonly formatted like US 20xx… A1).
If you share your target year range (for example, 2018–2024) or a specific assignee/company, I can suggest tighter query strings to reduce noise.
What if the goal is “histamine production” in a biological assay or drug context?
Histamine production can appear in:
- Diagnostic or assay methods (measuring histamine levels)
- Enzyme-related claims (HDC and decarboxylase activity)
- Therapeutics that inhibit histamine formation or release
- Food/fermentation processes (where histamine formation is an issue)
In those cases, add context terms:
- For assays: assay, detect, measurement, quantify
- For enzyme: inhibitor, substrate, enzyme, HDC
- For therapeutics: treatment, inflammation, allergy, mast cell
If you meant “histamine production” by microorganisms/fermentation, what should I search?
For food and fermentation patents, search terms often shift from human biology to process and spoilage. Try combinations like:
- histamine formation instead of production
- microorganism or bacteria plus histidine decarboxylase
- fermentation and biogenic amines (histamine is one of several)
- scombroid (fish-associated histamine issues)
This usually surfaces US filings about preventing or reducing histamine in products.
Can you paste the exact phrase you want and I’ll tailor the Google Patents query?
If you provide any of the following, I can generate a more exact search string:
- The relevant domain (human medical, assay, enzyme inhibitor, food/fermentation)
- A time window
- Any keywords you saw in the patent (e.g., “HDC”, “H1 receptor”, “biogenic amines”)
- A company/assignee name
