How long do patents last?
Short answer - it depends on the type of patent:
A design patent, which protects how something looks, typically lasts 15 years.
A utility patent, which protects the function of an invention, typically lasts 20 years.
A plant patent, which is fairly uncommon outside of the agricultural industry, typically lasts 20 years.
There are exceptions to the above-mentioned lengths of patent life. The government patent office may adjust the patent life, depending on various factors. Many issues can impact how long a patent lasts.
