Intellectual Property Rights
Trademark dilution is a trademark law concept which forbids the use of a famous trademark in a way that would lessen its uniqueness. In most cases, trademark dilution involves an unauthorized use of another's trademark on products that do not compete with, and have little connection with, those of the trademark owner.
An example of trademark dilution: a famous trademark used by one company to refer to software products, might be diluted if another company began using a similar mark to refer to cosmetic products.
The concept of trademark dilution developed in the 20th century to protect trademarks as a property right, securing the investment the trademark owner has made in establishing and promoting a strong mark.
It was in the 1990s that the United States enacted a law against trademark dilution. Even though the concept of trademark dilution was being discussed in academic circles in early 20th century, it was only later that the states began adopting trademark dilution laws.
Trademark law was originally focused on the need for consumer protection. Consequently, trademark law traditionally concerned itself with situations where an unauthorized party sold goods that are directly competitive with or at least related to those sold by the trademark owner.
A trademark dilution happens when the use of similar or
identical trademarks in other non-competing markets means that the trademark in and of
itself will lose its capacity to signify a single source. In other words, unlike ordinary
trademark law, trademark dilution protection extends to trademark uses that do not confuse
consumers regarding who has made a product. Instead, trademark dilution protection law
aims to protect sufficiently strong trademarks from losing their singular association in
the public mind with a particular product, perhaps imagined if the trademark were to be
encountered independently of any product (just the word Xerox for example).
The strength a trademark must have to deserve trademark dilution protection differs among jurisdictions, though it generally includes the requirement that it must be distinctive, famous, or unique. Such trademarks would include instantly recognizeable brand names, such as Samsung, or Sony, and unique terms that were invented (such as Exxon or Enron) rather than surnames (such as Ford) or ordinary words in language. Some jurisdictions require additional registration of these trademarks as defensive marks in order to qualify for trademark dilution protection.
Another way of describing the necessary strength of a
trademark may establish some basis for trademark dilution protection from a consumer
confusion standpoint. Truly famous trademarks are likely to be seen in many different
contexts due to branching out or simple sponsorship, to the extent that there may be very
few markets, if any, that a consumer would be surprised to see that famous trademark
involved in. A prime example may be the past involvement of Coca-Cola in clothing lines.
Trademark dilution is sometimes divided into two related concepts: blurring, or essentially basic dilution, which "blurs" a mark from association with only one product to signify other products in other markets (such as "Tata Pressure Cooker"); and tarnishment, which is the weakening of a mark through unsavory or unflattering associations. Not all trademark dilution protection laws recognize tarnishment as an included concept.
Prior to specifically targeted laws being adopted, trademark dilution protection was used in some jurisdictions to attack domain name infringement of trademarks.
