Trademark

A trademark is a word, phrase, design, or other feature that primarily serves to identify the source of a product or service (a mark that identifies a service may be called a service mark). Drawing from the principle that consumers have a right to know the source of the things that they buy, most governments have created legal protections for trademarks, allowing the owner of the mark to take legal action against another party that uses a mark without permission. As international trade has increased, countries have entered into various treaties which make it easier for a mark in use in one country to gain protection in others.

Along with patents and copyrights, trademarks represent one of the three primary areas of intellectual property law. The primary differences between trademark and other intellectual property regimes lie in the duration and the scope of what may be protected. While both patents and copyrights issue for a specific, limited time, trademarks can persist without end, so long as the mark is used to identify the goods for which it has been registered, or with which it is used.

Classification of marks by strength

In every system that permits the registration of trademarks, some determination must be made as to whether a proposed mark is registrable. The first inquiry into the registrability of a mark is whether the mark is strong enough to receive protection.

A generic mark, which is merely the name of the product itself, can not receive protection because all competitors must be given the right to describe their goods. A common example is the word "apple". A seller of apples could not use the word "apple" as a trademark, because that seller would then be able to prevent all others from using the word to describe their products. However, nothing prevents a seller of computers from using the name Apple for a brand of computers, as no other seller of computers needs to use the word apple to describe their products.
