"Intellectual property" (IP) refers to property rights in patents, inventions, trademarks, copyright and industrial designs. IP law has become increasingly complex and comprehensive as technology advances. (Source https://law.duke.edu/lib/researchguides/intprop/)
Intellectual property refers to any intellectual creation, such as literary works, artistic works, inventions, designs, symbols, names, images, computer code, etc.
Intellectual property law exists in order to protect the creators and covers areas of copyright, trademark law, and patents. (See U.S. Patent and Trademark Office USPTO) Thus, intellectual property is an umbrella term encompassing both copyright and industrial property, such as trademarks, patents, and inventions.
