The trademark symbol for unregistered trademarks is designated by the letters TM written in superscript style. In practice it will look like this: Product™ . It is used directly after the logo, mark, or slogan that is not registered. When a trademark is registered with the specific trademark office you will see an “R” in superscript surrounded by a circle after the logo, name or slogan. It will look like this: Product ®.
There is a proper procedure for displaying the trademark as described and companies frequently issue statements on the Internet regarding the appropriate and allowable usage and display of their trademark by another entity even in referencing the trademark.
Examples of Trade Marks: Name, Slogan, Logo, Shapes, Sounds / Tunes, Tastes, Textures, Three-dimensional Marks, Colors, Holograms, Motions / Multimedia, Positions, Gestures, Olfactory (smells / scents).
Transferring a Trademark
Trade marks can be transferred through assignment – in other words, trade marks may be bought or sold like other commodities. Alternatively, you may wish to license your trademarks to another manufacturer, who will then pay royalties for the use of your trademarks. A trademark, like a patent, may even be hypothecated to serve as security.
