What does “us histamine production” mean in Google Patents searches?
People often phrase searches like “us histamine production application” to mean one of two things on Google Patents:
1) They want patents filed in the United States about making or increasing histamine (a “production” process).
2) They want the United States patent (US) application documents for a particular histamine-related invention (the actual “US … application” record).
If you tell me the exact wording you used (or the inventor/company name), I can help narrow the right search pattern.
What to search on Google Patents for U.S. histamine production (practical query)
Use combinations of these keywords and filters in Google Patents:
- “histamine” AND (production OR biosynthesis OR manufacturing OR “microbial production” OR fermentation)
- “histidine decarboxylase” AND histamine (often tied to biosynthesis)
- (bioprocess OR “biocatalyst”) AND histamine
- “histamine” AND (process OR method) AND (US OR “United States”)
To target U.S. documents more directly, add:
- a filter for “Jurisdiction: United States” (on the left sidebar, if available), or
- include “US” / “United States” in the query terms.
What kinds of patents are usually tagged around histamine production?
Google Patents results typically cluster into a few technology areas:
- Microbial or enzymatic production of histamine (histidine decarboxylase pathways)
- Chemical synthesis routes for histamine (less common than biocatalysis in modern phrasing)
- Equipment/process patents for fermentation/bioprocessing that generate histamine
- Uses of histamine or histamine-producing methods in specific applications (research, medical formulations, or industrial processes)
How to distinguish “production” patents from “use” patents
A patent can mention histamine but not be about producing it. To focus on production:
- Add “method for producing histamine” or “producing histamine”
- Add process terms like “fermentation,” “culturing,” “bioreactor,” “enzyme,” or “biocatalyst”
- Avoid overly broad intent terms like “treatment” unless you want therapeutic uses
If you meant “US application” (not “U.S. histamine production”)
Google Patents shows records for:
- “US … A1” (published application)
- “US … B1/B2” (granted patent)
If you have an application number or publication number, searching exactly like:
- “US[publication-number]”
often pulls up the correct record faster than keyword searching.
Quick next step
Reply with one of the following, and I’ll craft a more precise Google Patents query (and explain what to look for in the results):
- the inventor/company name you’re searching for, or
- a patent/application number you have (e.g., “US 20xx/xxxxxxx”), or
- whether you mean “histamine produced by microbes/enzymes” or “histamine used in medicines/treatments.”
