The Basics of Design Patents

Before we answer “How long does a design patent last,” we should learn the basics of design patents. A design patent is a form of intellectual property protection that safeguards the unique appearance or “ornamental” aspects of an invention, as opposed to its functional features. 

Design patents, granted by the USPTO, can be used to protect the distinctive looks of products like lamps, app icons on mobile phones, or any other novel and attractive design.

Design Patents vs Utility Patents

  • Design patents: Protect the visual elements or aesthetics of a product. They do not cover how it functions or works. For example, if you create a new shape for a water bottle that has never been seen before but does not affect its functionality in any way, this would fall under design patent protection.
  • Utility patents: Cover inventions with novel functionalities or improvements over existing technology. These types of patents protect how an invention works rather than just its appearance. Examples include mechanical devices like engines or electronic gadgets such as smartphones.

In some cases, both design and utility patents may be filed for the same invention if it has both unique aesthetic qualities along with innovative functional aspects.
