Imagine you have a special toy that you love to play with. It has a name that you and your family call it, and everyone knows that's your toy. But then, someone else comes along and sees how much you like your toy, so they make a toy that looks almost exactly like yours and even gives it the same name.
This makes you upset because it feels like they are trying to take credit for your toy and your idea. That's kind of what it's like when someone infringes on a trademark. A trademark is like a special name or symbol that represents something, like a company or a product.
If someone makes a product or uses a name that is very similar to someone else's trademark, it can be considered infringement. This means they are using something that doesn't belong to them and it can be against the law. It's important to respect other people's trademarks and not try to copy them.
