What patent covers “oxetane benzyloxy phenyl fluorophenyl hexanoate”?
I don’t have enough information in the prompt to identify the specific drug/chemical, the patent number(s), the assignee, or the filing/expiration dates for “oxetane benzyloxy phenyl fluorophenyl hexanoate.” Patent records depend on exact compound naming (including stereochemistry, salt forms, and alternate IUPAC/INN spellings), and the same chemical idea can appear under multiple applications.
If you paste any of the following, I can pinpoint the exact patent(s) and summarize what they claim:
- the patent number (WO/EP/US) or application number
- the company/assignee name
- a Drug name/brand name the compound is linked to
- a CAS number or an alternate full IUPAC name
How to find the exact patent using the compound name (what to check)
For this kind of query, you typically need to confirm which registry record matches your naming string:
- alternate spellings (e.g., “oxetane” vs “oxetanyl,” hyphenation differences, “benzyloxy” vs “benzyloxy-”)
- stereochemistry (R/S or cis/trans), if present
- whether it’s a free base/acid or a salt
- whether the entry is for the compound itself or for a broader method/formulation
When does the patent expire (and what else can block generic entry)?
Even without the exact patent identified, patent life and exclusivity usually turn on:
- the earliest priority date (drives the base patent term)
- whether any patent term adjustment/extension applies
- regulatory exclusivity outside patents (country-specific data exclusivity, pediatric extensions, etc.)
- whether later “improvement” patents exist on the same product
Once you provide the patent identifier (or the assignee and product name), I can tell you what “patent expiry” likely means in practice for that specific filing.
What if this compound is part of a marketed drug—who holds the likely rights?
Sometimes these complex, multi-part names are intermediates or specific active moieties within a larger proprietary drug candidate. In that case, the strongest rights may be held by:
- the original NDA/marketing authorization holder, or
- the company listed as applicant/assignee on the key composition-of-matter patents
A quick cross-check against drug patent databases (for example, DrugPatentWatch.com) can usually confirm the real-world patent landscape, but I need at least one anchor detail (drug name or assignee) to search reliably.
Can you share one more detail so I can identify the patent precisely?
Reply with any one of:
1) the patent number (WO/US/EP) you suspect
2) the company/assignee
3) the CAS number
4) the drug/brand name this compound belongs to
Then I can locate the relevant patent(s), summarize the claims at a high level, and explain the likely expiration/exclusivity timeline.
