FAQ: Questions and Answers

[back to notice text] Question: What are the limits on dilution? Answer: The Federal Trademark Dilution Act of 1995 (FTDA, 15 U.S.C. 1125) prohibits the commercial use of a famous mark if such use causes dilution of the distinctive quality of the mark. A mark may be diluted either by "tarnishment" or "blurring." Tarnishment occurs when someone uses a mark on inferior or unwholesome goods or services. For example a court found that a sexually explicit web site using the domain name "candyland.com" diluted by tarnishment the famous trademark "CANDY LAND" owned by Hasbro, Inc. for its board games. Blurring occurs when a famous mark or a mark similar to it is used without permission on other goods and services. The unique and distinctive character of the famous mark to identify one source is weakened by the additional use even though it may not cause confusion to the consumer. The following uses of a famous mark are specifically permitted under the Act: 1) Fair use in comparative advertising to identify the goods or services of the owner of the mark. 2) Noncommercial uses of a mark. 3) All forms of news reporting and news commentary. In addition, the courts have differed as to what constitutes a "famous" mark under the FTDA. In some cases the courts have said that the famousness requirement limits the Act to a very small number of very widely known marks. Other courts, however, have accepted lesser-known marks as PANAVISION, WAWA and EBONY as being famous and yet others have said that merely being famous in one's product line is sufficient. Many states also have antidilution laws protecting mark owners. [back to notice text] Question: How can I find out if someone has a valid trademark? Answer: It isn't easy. In the United States, a trademark owner isn't required to register the mark anywhere, so there is no single central list of them all. Unlike most other nations, registration here is optional. Many owners do register their marks with the government, however, to better notify the world of their claims. Each state has its own trademark registry for goods and services sold locally. For companies that sell in more than one state, there is a US federal registry that is accessible online through TESS. TESS is searchable by key word as well as by registration number. Because registration is not required, however, a word might still be a protected mark even if it doesn't appear in any of these locations. When a company is selecting a new brand, its trademark attorney will usually conduct a "trademark availability" search which will look in many different locations to try and ferret out competing uses of the desired name. Business directories, Internet search engines, telephone directories are other searched sources. Multi-national vendors will search trademark registries in foreign nations as well. Even the most exhaustive search will not be conclusive, however, but it will usually indicate that if there is any other commercial use, it is probably limited to a very local area. It is OK to use the same mark as another company, so long as the new use isn't likely to confuse consumers. [back to notice text] Question: Where can I find federal trademark law? Answer: To be protected by federal trademark law, the marked goods and services must be used in interstate commerce. Federal trademark law is known as the Lanham Act. It protects marks that are registered with the United States Patent & Trademark Office as well as those that are in use but never registered. Court opinions and United States Patent & Trademark Office (USPTO) regulations also interpret trademark rights and remedies. See the links to court sites provided by the Legal Information Insitute.

Answer: Goodwill is a business or trademark owner's image, relationship with customers and suppliers, good reputation, and expectation of repeat patronage. It is the value a trademark owner builds in a brand. [back to notice text] Question: Where can I find state trademark law? Answer: Each state has its own laws governing use of trademarks within its borders. To locate the trademark laws of the 50 states, use the Legal Information Institute links. Both legislation and court opinions create trademark rights and remedies. If marks are used in interstate commerce, then federal law will also apply.
