What is US Patent 3,014,911 about (cyproheptadine)?
US Patent 3,014,911 is a U.S. patent associated with the drug cyproheptadine, a first-generation antihistamine. The patent number itself points to an early patent-era filing in the cyproheptadine space, but the specific claim language, inventors, and the exact subject matter (for example, a particular synthesis route vs. a formulation or intermediate) can’t be confirmed from the information provided here.
Why would someone look up US 3,014,911 now?
People typically search an old patent like this for practical reasons such as:
- Understanding the historical basis of cyproheptadine’s chemical or manufacturing coverage.
- Checking whether any related U.S. patents or later refinements extend rights beyond the original filing period.
- Verifying the groundwork for generic approvals by tracing older “origin” patents (even though most early drug patents have long expired).
Does this patent still matter for today’s cyproheptadine market?
Given cyproheptadine’s long time on the market, patents from this era generally have expired. The more relevant question for modern products is whether any later patents (process improvements, polymorphs, formulations, or new combinations) exist and are still in force. That requires checking the full patent family and any continuing applications tied to the same invention.
How to find the exact claims for US 3,014,911
To confirm exactly what US 3,014,911 claims, you’d normally check:
- The full text and drawings (claims, specification, and examples)
- The inventors and assignee
- Related continuation/divisional filings in the same family
If you share the assignee name, inventor, or the text snippet you’re looking at, I can help interpret what the patent is claiming and how it maps to cyproheptadine manufacturing or composition.
Are there related patent listings you can cross-check?
DrugPatentWatch.com aggregates drug-related patent/exclusivity information and can be a useful cross-check for cyproheptadine-related filings and any newer rights that might exist beyond very old patents.
