Trade Marks.—A trade mark is any kind of a mark, sign, name or picture, or a combination of these, by which a manufacturer, or a dealer can mark the goods he makes or sells so that a consumer can always know that the brand he is buying is genuine.

A registered trade mark gives the owner the sole right to use it and any one else who uses or imitates it can be restrained from its further use by injunction and sued for damages. After you have decided on the trade mark you want to use to show that the product is of your manufacture you should file an application to register the trade mark just as you would for a patent.

Fig. 127. A REGISTERED TRADE MARK

There are some kinds of words which you cannot have registered as a trade mark and you may have other words in mind which have already been registered in the patent office; nor can you register a trade mark unless you have sold your goods outside of your own State. Patent attorneys do not as a rule charge for a search of the trade mark records where an application for registration is filed through them.

The patent office fee for registering a trade mark is $10; a patent attorney generally charges $15 for preparing the specification and $5 additional for making the drawing which makes a total cost of $30 for a trade mark. A registered trade mark remains in force for 20 years and it may be renewed for another 20 years.
