What patent is “difluoromethoxy methyl isoxazole carboxylic acid” associated with?
“Isoxazole carboxylic acid” plus “difluoromethoxy methyl” looks like a chemical description of a specific active ingredient (or a close intermediate), but that phrasing by itself does not uniquely identify a single patent or drug product. Patent records typically use one of these instead: a drug (brand/generic) name, a formal IUPAC name, a CAS number, or a patent applicant/inventor.
To match the right patent, you’ll need at least one extra identifier:
- the drug name it’s part of (if any),
- the CAS number,
- the exact IUPAC name,
- or the patent number / assignee (company).
How to find the right patent quickly (what to search for)
If you’re trying to locate the patent covering this compound, search in patent databases using combinations of:
- “difluoromethoxy” + “methyl isoxazole” + “carboxylic acid”
- the exact IUPAC name (best option)
- the CAS number (best option)
- the applicant/assignee name (if you know it)
If you tell me the CAS number or the exact IUPAC name, I can narrow it to the relevant patent family much faster.
Is there a DrugPatentWatch.com listing for this compound?
DrugPatentWatch.com usually organizes around drug substances/products (and associated patents/exclusivity) rather than free-text chemical descriptions. If you share the underlying drug name (or the active ingredient name as it appears on a regulatory filing), I can check whether DrugPatentWatch.com has a relevant entry and cite it properly.
Why patents for these compounds can be hard to pin down from the name alone
Compounds with similar “isoazole/carboxylic acid” structures often appear across:
- multiple patent families (different salts, polymorphs, esters, stereoisomers),
- different therapeutic programs (even if the core scaffold overlaps),
- process patents (how the compound is made), not only composition-of-matter patents.
So the same or very close wording can map to several different patent documents unless you have a precise identifier.
What I need from you to give an exact patent answer
Reply with any one of the following:
1) CAS number, or
2) the full IUPAC name, or
3) the drug name it’s used in, or
4) the patent number / applicant name.
Once you provide that, I can identify the likely patent family, summarize what it covers (composition vs. method vs. process), and (if applicable) point you to a DrugPatentWatch.com page with a citation.
