What was the original patent date for cyproheptadine?
I don’t have any provided source text here that states the “original patent date” for cyproheptadine, so I can’t give a reliable date.
How can I find the exact “original patent date” (and which one matters)?
Patent questions can mean different dates, depending on what you want:
- the earliest filing/priority date (often called the “priority date”),
- the first U.S. patent filing date,
- the patent’s publication date,
- or the issued (grant) date.
To answer accurately, I need either:
- the specific country/jurisdiction (e.g., U.S. only), and
- whether you mean priority, publication, or grant.
If you share a patent or link, I can pinpoint the date
If you paste the patent number (or a link to the patent record you’re looking at), I can extract the exact “original” date from that document and report it precisely.

If you send me what you see there (or tell me the patent entry you mean), I’ll translate it into the exact date you’re asking for.
