Okay, so imagine you have a toy that you really love playing with, and one day, your friend comes over with the exact same toy. You both start playing with your toys, but then your friend starts copying everything you're doing. You get upset because you feel like they're not being original and it's not fair to you.
That's kind of what happened between two big companies called Motorola Mobility and Apple Inc. They both make phones and tablets (kind of like toys for grown-ups), but Motorola started making their phones and tablets look and work like Apple's. Apple got really upset because they spent a lot of time and money designing their own phones and tablets, and they didn't want Motorola to just copy them.
So, Apple decided to take Motorola to court to try and make them stop copying their designs and technology. The court had to decide if Motorola really did copy Apple's ideas, and if they did, how much money they should pay Apple for it.
It's kind of like if you made a really cool piece of artwork and your friend copied it exactly, you would feel upset and think they should come up with their own ideas. Overall, this court case was about making sure companies can't just copy each other and that they have to come up with their own ideas.
