Okay kiddo, let's talk about different types of intellectual property!
First, we have what's called "background intellectual property." This is all the stuff that came before the thing you're creating - like if you're writing a book, the background intellectual property would be all the books you've read before, or the experiences you've had that inspired your story.
Next, there's "foreground intellectual property." This is the thing you're actually creating - so in the book example, it's the actual words and plotline that you're writing.
Then, we have "sideground intellectual property." This is anything that's related to your creation but not strictly a part of it - for instance, if you're writing a book and you create some really cool illustrations, those would be considered sideground intellectual property.
Finally, there's "postground intellectual property." This is anything that comes after your creation that's related to it - for example, if your book becomes really popular and someone makes a movie out of it, the movie would be postground intellectual property.
So to sum it up: background is everything that came before, foreground is the thing you're creating, sideground is related but not part of it, and postground is anything that comes after. Got it, kiddo?
