Copyright, trademark and patent are three different legal concepts all based around the idea that a person or entity should have some legal means to protect their intellectual property (IP). In the modern business environment, intellectual property can be important assets owned by a firm, and no matter what form that IP takes, it is important that not only do firms have the ability to prevail in these suits in the long-run, but also have the ability to protect their IP while their claim is still pending. That is where a temporary restraining order (TRO) or preliminary injunction can be a truly essential tool.
A trademark protects the trade names and marks used by business. As firms often place a great deal of value in the goodwill and brand familiarity of those names, the use of those marks, or marks similar, can often be a serious problem that needs immediate redress.
