    Patents can be renewed, to my knowledge, and “for decades” as in “since the 90s”.

      Usually, patents have a lifetime for 20 years. Maybe you get an extension for 5 years. From were do you have the info that patents can be renewed?

      Patents can’t be renewed. After expiring, they become public domain.
