How long do your intellectual property rights actually last?

In short: From the logos on your shoes to the secret recipes of global giants, intellectual property has different expiration dates. This guide breaks down the legal lifespans of patents, trademarks, copyrights, and trade secrets.

The duration of protection depends entirely on the type of intellectual property. Utility and plant patents protect inventions for 20 years from the filing date, while design patents cover the aesthetic look of a product for 15 years. In contrast, trademarks—which protect brands like Nike—can last indefinitely as long as the company remains active.

Copyrights and trade secrets also persist as long as the company exists, provided the trade secret remains non-public, actively guarded, and economically valuable to competitors. A unique category exists for the image and likeness of famous individuals, such as Colonel Sanders’ face; these rights typically last for the duration of the individual's life.
