Unity owned ECS patent uses techniques described in 2013 Stack Exchange post (github.com)

The 2013 StackExchange post [^1] describes what is now commonly called an "archetype" based ECS architecture that was implemented as compile time archetypes in the author's open source project in Feb 2018 ^3. A similar ECS model was described later in the June 2018 patent filed by Unity ^2 and active since 2020.

It's useful to bring visibility to the issue for the inevitable patent trolling that will occur in the future.

Corporate loves to steal ideas and patent it/copyright it so nobody else gets to steal it next, even the original author of a technique.
