Creation of an established Trademark involves a lot of monetary expenses, time and hard work and a lot other strain and pains. With assignment of trademark, the owners of the same can liquidate the value of the brand, which he built with his efforts. With trademark assignment, the mark could establish even sounder as a new team joins to business with proper terms and conditions to retain the quality of products/services, served through the assigned mark and violation of the terms of use by assignee may end up in termination of agreement.
