Field-of-use limitation

Imagine you have a toy car, and it can go really fast. But your mom says you can only play with it in your room, not outside. That's like a field-of-use limitation. It means you can only use the toy car in a certain place or for a certain purpose.

In the grown-up world, field-of-use limitation often comes up in business or legal agreements. Let's say a company invents a new tool that helps people cut things really easily. The company might say that other companies can buy the tool, but they can only use it for cutting fabric, not for cutting metal. That's a field-of-use limitation.

The idea is to protect the invention or product from being used in a way that the original company doesn't want it to be used. It can also be a way to make sure that different companies can use the same invention without competing directly with each other.

So, just like how your mom limits where you can play with your toy car, companies can limit where and how their inventions can be used.
