Laches, defense of :
A defense based upon plaintiff’s inexcusable delay in asserting or attempting to enforce trademark rights. This doctrine is based on the theory that equity rewards the vigilant and not those who slumber on their rights.
Labels, trademark protection of :
Labels on goods can be protected under trademark law if the features on the label for which trademark protection is claimed identifies source for consumers, and if such features are not functional. Product labels fall into a rapidly expanding area of trademark protection for trade dress.
Lanham Act :
Otherwise known as the Trademark Act of 1946, this statute provides protection against trademark infringement, trademark dilution, and false designation, description or representation. The act also governs procedures for federal trademark registration. The Act is contained in Title 15 of the United States code, sections 1051-1127.
Legal strength of a trademark :
Strength of a mark can be measured on two different levels; marketing strength and legal strength. Words that describe very closely the underlying good or service they represent have strong marketing potential, since such marks immediately communicate to customers what the product actually is or does. An example is “Quick Fix Radio Mix.” This tells the customer immediately that it is a substance that fixes radios quickly. The problem with using descriptive marks such as these is that they are weak from a legal perspective. The legal strength of a mark is generally measured by its distinctiveness, not its descriptiveness. In fact, distinctiveness and descriptiveness are almost two ends on the same spectrum. Generally speaking, the more distinctive the mark, the stronger is the legal protection available for that mark, but the less ability the mark has to communicate with the consumer. Distinctive marks are those that are coined or fanciful (made up), or suggestive (suggesting qualities of the underlying products, without plainly describing them).
Letters, trademark protection of :
Alphabetic and Alphanumeric characters can be protected under trademark law, and indeed comprise the most common form of trademark, otherwise known as textual or lingual marks. Such marks receive their broadest protection if they are used as trademarks in block-letter format, i.e. without specialized fonts, coloring or other stylized features. Alternatively, if lingual marks are used with stylized features, but registered as block letters alone, or used in a variety of different stylized formats, then protection can more reasonably extend to all similar configurations of letters.
License :
An agreement between a trademark owner and one or more other parties that allows the other parties to make limited, specified use of the trademark in question. Licensing of trademarks can result in the loss of the trademark unless the license arrangement provides for a certain degree of control over the licensed use.
Licensee :
The party to whom a trademark owner grants a license to use a trademark.
Licensor :
The trademark owner who is licensing a trademark to the trademark licensee(s).
Likelihood of Confusion Test :
An analysis of whether confusion is caused when the mark in question is used to identify the same or closely related goods or services as an existing mark. If the relevant consuming public will be confused or mistaken about the source of product or service sold using the mark in question, then likelihood of confusion exists, and that mark can be excluded from being used by the prior mark owner. The likelihood of confusion test is one of several examinations conducted by the U.S. Patent and Trademark Office in determining whether to approve an applicant’s trademark application. The test is also used in trademark infringement lawsuits to determine whether or not the defendant is liable for infringement.
Lingual Marks :
These are trademarks in the form of either words or phrases, and are the most widely used kinds of marks. Depending on the meaning of the word or phrase, these marks have more or less legal strength.
Litigation :
A lawsuit. In order to litigate a trademark conflict, there must be a legal cause of action such as infringement or dilution. Trademark litigation often occurs on a very fast schedule since the plaintiff usually requests the court to grant a temporary injunction to stop the alleged trademark infringer from using the mark until the whole dispute can be resolved through a longer process. If a court grants the injunction, the defendant typically settles quickly and changes marks because the incentive for litigating a mark that cannot be used (at least in the short term) is obviously prohibitive since goodwill will have to be generated under a new name.
Lost profits, as a measure of damages :
The plaintiff’s lost profits may be awarded as damages in a trademark lawsuit, but monetary relief is generally reserved for cases of intentional infringement. To receive plaintiff’s lost sales as damages, the plaintiff must show that if it were not for the defendant’s infringing activities the plaintiff would have had a certain number of sales that were not in fact had. Proving this is often difficult since there may be a number of reasons besides defendant’s infringing use of the mark that could account for plaintiff’s lost sales. As such, a market survey may be necessary to prove such damages.
