ECS has been around since like 2007 and there's plenty of public prior art on this, but suuuuuuuuuure Epic Games yep you guys totally invented the concept and deserve a monopoly on use of the technology. This might directly affect several projects I have if they choose to use this patent offensively. This further cements my disgust with IP law, honestly I'd rather we just have information anarchy when it comes to abstract computer stuff at this point.
