What should I do if someone uses my design without permission?
After discovering that your design has been used by a third party without permission, try to contact the offender and send a request to stop infringement. It is recommended to include a time limit to respond, so you know when to take another step to stop infringement if necessary. If the offender does not agree to stop using the design, it is possible to pursue legal action. In any case, you will have to prove that someone else is using a design that is confusingly similar to your registered design, however, it does not have to be identical.
