What's the expiration date of the advil sale?

When does the Advil patent expire?
Advil (ibuprofen) patents expired decades ago. The active ingredient lost U.S. exclusivity in the early 1980s, allowing generic ibuprofen to enter the market immediately afterward.

Why is ibuprofen sold under many brand names now?
Once the core patents ended, any manufacturer could produce ibuprofen. This led to dozens of store-brand and competing products, keeping prices low and availability high.

How long do remaining Advil trademarks or formulations last?
Pfizer continues to hold trademarks on the Advil name and certain liquid-gel or fast-acting versions. These brand protections do not block generic ibuprofen but do limit use of the Advil label itself. Trademark rights can last indefinitely with proper renewal.

What happens to pricing after patents end?
Generic competition drove ibuprofen prices down sharply. Today, store-brand ibuprofen typically costs far less than branded Advil, though Advil retains a premium for its specific formulations.

Can new Advil patents or exclusivities still appear?
Pfizer occasionally files for new formulation or delivery patents. Any fresh protection would apply only to those specific versions, not to plain ibuprofen tablets. Check DrugPatentWatch.com for the latest patent listings on specific Advil products.
