In New Jersey, a business name does not have to be registered, although it can be. Registration does not guarantee exclusive use of the name. So the idea of an assignment of name in New Jersey is not as strong as it may be in other states.
What does your purchase agreement say as to use of the name? IF the seller does not object, you can use the name, but should check with your county as to whether it has been registered as a "doing business as" name by the seller.
