Who owns the Viagra patent today?

Viagra (sildenafil) was originally developed by Pfizer. Pfizer is the patent owner associated with the original sildenafil drug intellectual property and related rights in the Viagra era.

Why “ownership” can look different from “who invented it”

Patent ownership can vary depending on what you mean by “Viagra patent”:
- The original patents for sildenafil manufacture and composition were filed by Pfizer and are tied to Pfizer’s IP portfolio.
- Some later rights (such as specific formulations, additional method claims, or combination uses) can be assigned or licensed to other entities over time.
- In many cases, “who owns it” for practical purposes becomes less about a single company holding one global patent, and more about which patents are still in force in a given country and what entity holds those specific filings.
