Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.



Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

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

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

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?
