Technically IP law covers patents, trademarks, copyright, and designs (sometimes also called design patents). Patent protection is 20 years (plus a little bit extra under certain conditions. Trademarks is indefinite in theory. Copyright (in many jurisdictions) is 70 yrs after death or 50 yrs for certain works (e.g., music recordings). Designs, I’m not really sure.
Then patent law is better than intellectual property law, I think it’s 50 years after the creator dies and there are loopholes for companies
