What is the term length for design patents filed on or after May 13, 2015?

• A. 10 years from grant
• B. 15 years from grant
• C. 20 years from grant
• D. 25 years from grant.

Answer: (B)

Design patents filed on or after May 13, 2015, have a term length of 15 years from the date of grant. This change came about with the implementation of the Leahy-Smith America Invents Act (AIA), which modified the duration of design patents. Prior to this, design patents granted after certain dates had different term lengths, which can lead to confusion regarding their lifespan. It's essential to understand that this 15-year duration applies specifically to design patents under the current law, distinguishing them from utility patents, which typically last for 20 years from the filing date. When considering the nature of design patents, they protect the ornamental design of a functional item rather than its utility, which underscores why patent term lengths can vary based on the type of patent and the laws in effect at the time of filing.
