This is a student competition. If you want to see those students pleasing to the eye, authorize them to use them.
If you don't like them, then refuse.
You can also communicate with them. If you think they really promoted your patent effectively and made full preparations in all aspects, you should give them some money instead of letting them do it better. This is a patent promotion activity.
They are entrepreneurial competitions and will not participate in generating economic benefits before the end of the competition.
For pure student activities, don't worry about what will be bad for you, unless your patent has no information, for fear that others will find that your patent can be invalidated.
