Note that both trademarks and service marks differ from trade names, which identify the companies themselves.
A trade name can function as a mark, however, insofar as a company uses the business name as marks on their products, or in connection with a service it offers.
A trademark is a word, name, symbol or device which is used in trade with goods to indicate the source of the goods and to distinguish them from the goods of others. A servicemark is the same as a trademark except that it identifies and distinguishes the source of a service rather than a product. The terms trademark and mark are commonly used to refer to both trademarks and servicemarks. Trademark rights may be used to prevent others from using a confusingly similar mark, but not to prevent others from making the same goods or from selling the same goods or services under a clearly different mark. Trademarks which are used in interstate or foreign commerce may be registered with the Patent and Trademark Office.
The registration procedure for trademarks and general information concerning trademarks is described in a separate pamphlet entitled Basic Facts about Trademarks.
A trademark can be considered any name, symbol, figure, letter, word, or mark adopted and used by a manufacturer or merchant in order to designate his or her goods and to distinguish them from those manufactured or sold by others.
A trademark is a proprietary term that is usually registered with the Patent and Trademark Office to assure its exclusive use by its owner.
It can also be considered a distinctive mark or feature particularly characteristic of or identified with a person or thing.
Circumstances may prevent your keywords from being approved. For example, if you have duplicate keywords, you will receive notice of it as soon as you try to set up your campaign, or if you have keywords that are trademarked, they may be disapproved for legal reasons.
If a keyword that you want to use is not approved, try selecting a similar phrase.
Each of the keywords in the list shown on the Ad Group page is actually a link to one more level in detail. If you click a keyword, you are taken to a keyword detail page. This page shows information such as your maximum bid for the keyword, a forecast for position or number of times the ad will be shown based on your budget, and a prediction for how much higher you will rank if you increase your daily bid.
Editing features, like keyword replacement and changing your destination URL, are also available.
