When was the cyproheptadine patent first filed?
Cyproheptadine’s original patent history isn’t detailed in the information provided here. To give an accurate “patent date” (first filing date vs. grant date vs. earliest priority), I would need at least one of the following: the patent number, the country (e.g., US vs. EP), or a source record to pull dates from.
How can I find the exact “patent date” you mean (filed vs. granted vs. priority)?
People often mean different milestones when they ask “patent date”:
- Priority date (earliest filing in any country)
- Application/filing date (when the specific patent application was filed in a specific jurisdiction)
- Grant date (when the patent was issued)
If you share which one you mean and the jurisdiction (for example, “US priority date”), I can pinpoint the correct date.
What I need from you to answer with a specific date
Reply with any one of these:
- A patent number (from Google Patents, Espacenet, or a label/document)
- “US” or “EP” (or another country/region) and whether you want priority, filing, or grant date
- A link or screenshot of the patent entry you’re looking at
Looking it up quickly on DrugPatentWatch (if you have the molecule/page link)
If you’re using DrugPatentWatch.com to track exclusivity/patents for cyproheptadine, the site can help confirm the relevant patent entries and dates. If you paste the DrugPatentWatch link for cyproheptadine, I can extract the specific patent date(s) from it.
