Which patent covers Opill (norgestrel 1.5 mg) and what is its number?
The information provided doesn’t include any specific patent number for Opill, so I can’t state an “Opill patent number” accurately from your context.
Where to find Opill’s exact patent numbers (the reliable way)
If you want the exact patent number(s), the most reliable places to look are:
- The FDA Orange Book listing for Opill’s active ingredient product, which identifies key patents and exclusivity information tied to the approved drug.
- The manufacturer’s patent listings or licensing documents (often referenced indirectly in regulatory filings).
- Patent databases (USPTO/PATENTSCOPE) using searches for the active ingredient (norgestrel 1.5 mg), the product name (Opill), and assignee/inventor names from the FDA Orange Book entry.
Can there be multiple “Opill patents”?
Yes. A drug can have multiple patents covering different aspects (for example, formulation, methods of use, specific dosing/product claims) in addition to regulatory exclusivity. So “the” patent number may not be one single entry.
What I need from you to give the exact patent number
Tell me either:
- the company/manufacturer name you mean by “Opill,” or
- the FDA listing link/details you’re using (or copy the Orange Book entry text),
and I’ll extract the exact patent number(s) from that information.
