How long does a design patent last from the filing date?

A design patent lasts for 15 years from the date of grant if the application is filed on or after May 13, 2015. This is due to the Patent Law treatises and amendments that specify the duration of design patents, which are meant to protect the ornamental design of a functional item.

Prior to this change, the term for design patents was 14 years. However, with the transition in 2015, the protection period increased. As such, once granted, a design patent provides the holder with exclusive rights to the ornamental aspects of their design for a significant period, allowing them to prevent others from making, using, or selling the patented design without permission.

Understanding the term of design patents is crucial for entities involved in innovation, as it informs their strategies regarding product development and market competition.
