What patent is associated with “cyclooctylvinyl phenyl”?
The phrase “cyclooctylvinyl phenyl” is not specific enough to identify a single, well-known compound or a single, widely published patent without additional details (for example: the patent holder, country, year, CAS number, or the exact chemical name/structure). Patent searches usually require at least one of those identifiers to avoid pulling unrelated filings that use similar sub-strings (like “vinyl phenyl” or “cyclooctyl”).
How to find the right patent for this compound name (fastest path)
If you want the correct patent record, the most reliable approach is to search using one of these:
- The exact chemical name as written in filings (including stereochemistry or salt form if any).
- A CAS Registry Number for the compound (best single key).
- The patent applicant/assignee (company or university).
- The filing jurisdiction (e.g., US, EP, WO) and approximate year range.
- Structural identifiers (SMILES/InChI) to match substance definitions across databases.
Common patent databases to use for this workflow include Google Patents and Espacenet, where you can combine “cyclooctyl” + “vinyl” + “phenyl” with an assignee name or CAS number to narrow to the correct application.
What I need from you to locate the specific patent(s)
Send any one of the following, and I can help you narrow to the exact patent family and key claims:
1) The patent number (e.g., “US20xx…”, “WO…”, “EP…”)
2) The company/assignee name
3) The country/jurisdiction and approximate year
4) The CAS number (or SMILES/InChI)
5) The full IUPAC name as shown on the label or document
Are there multiple patents for similar “cyclooctylvinyl phenyl” structures?
Yes. Even when the core motif is similar, patent families often split across:
- Different substituents on the phenyl ring.
- Different positions of the vinyl group.
- Different ring attachment points (cyclooctyl orientation).
- Different salts, polymorphs, or formulations.
- Different intended uses (drug vs. intermediate vs. polymer/plasticizer vs. coating additive).
So the same “text fragment” can map to multiple different chemical entities and different patent scope.
If your goal is freedom-to-operate: what to check in the patent
Once the correct patent(s) are identified, the key questions are:
- What is claimed: the compound itself vs. a method of making it vs. a composition containing it.
- Whether claims cover all isomers/salts or only a specific example.
- Expiration posture: filing date, priority date, and whether term adjustments/extensions apply (jurisdiction-dependent).
- Whether later continuation/divisional filings in the same family expand claim scope.
