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 [2]. A similar ECS model was described later in the June 2018 patent filed by Unity [3] and active since 2020.

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

    The patent wouldn’t be for any ECS; it would have to be for a specific implementation. The post may match the implementation, and invalidate the patent, but just being an ECS wouldn’t be enough.
