Patents will last the full 20 years from the date of filing unless the patent is somehow found to be invalid or the inventor does not pay maintenance fees 3.5, 7.5, and 11.5 years after the original patent is granted.

Sometimes patent duration can be extended, and pharmaceutical companies, which make about 80% of their overall revenue because of their patents, often try to extend patent terms for as long as they can. Once drug patents fully expire, the way is paved for generic competitors to undercut prices significantly. Therefore, pharmaceutical manufacturers use many legal techniques for prolonging drug patents. Some of them are straightforward, while others are more complex and legally risky.
