Final answer:
There are four types of intellectual property rights: trademarks, copyrights, patents, and trade secrets, each with its own duration of protection.
Step-by-step explanation:
Intellectual property rights include trademarks, copyrights, patents, and trade secrets. Trademarks are protected indefinitely as long as they are in use. Copyrights are typically protected for the creator's lifetime plus 70 years.
Patents are protected for 20 years from the filing date. Trade Secrets are protected as long as the information remains confidential.
