A trademark is a word, phrase, or logo that identifies the source of goods or services. Trademark law protects a business' commercial identity or brand by discouraging other businesses from adopting a name or logo that is "confusingly similar" to an existing trademark. The goal is to allow consumers to easily identify the producers of goods and services and avoid confusion.
Passing off is a common law tort which can be used to enforce unregistered trade mark rights. The tort of passing off protects the goodwill of a trader from misrepresentation.
The Lanham (Trademark) Act (Pub. L. 79–489, 60 Stat. 427, enacted July 5, 1946, codified at 15 U.S.C. § 1051 et seq. is the primary federal trademark statute of law in the United States. The Act prohibits a number of activities, including trademark infringement, trademark dilution, and false advertising.
Trademark dilution is a trademark law concept giving the owner of a famous trademark standing to forbid others from using that mark 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. For example, a famous trademark used by one company to refer to hair care products might be diluted if another company began using a similar mark to refer to breakfast cereals or spark plugs.
In trademark law, confusing similarity is a test used during the examination process to determine whether a trademark conflicts with another, earlier mark, and also in trademark infringement proceedings to determine whether the use of a mark infringes a registered trademark.
A concurrent use registration, in United States trademark law, is a federal trademark registration of the same trademark to two or more unrelated parties, with each party having a registration limited to a distinct geographic area. Such a registration is achieved by filing a concurrent use application and then prevailing in a concurrent use proceeding before the Trademark Trial and Appeal Board ("TTAB"), which is a judicial body within the United States Patent and Trademark Office ("USPTO"). A concurrent use application may be filed with respect to a trademark which is already registered or otherwise in use by another party, but may be allowed to go forward based on the assertion that the existing use can co-exist with the new registration without causing consumer confusion.
In the United States, trademark law includes a fair use defense, sometimes called "trademark fair use" to distinguish it from the better-known fair use doctrine in copyright. Fair use of trademarks is more limited than that which exists in the context of copyright.
A trademark is a type of intellectual property consisting of a recognizable sign, design, or expression that identifies products or services from a particular source and distinguishes them from others. The trademark owner can be an individual, business organization, or any legal entity. A trademark may be located on a package, a label, a voucher, or on the product itself. Trademarks used to identify services are sometimes called service marks.
Substantial similarity, in US copyright law, is the standard used to determine whether a defendant has infringed the reproduction right of a copyright. The standard arises out of the recognition that the exclusive right to make copies of a work would be meaningless if copyright infringement were limited to making only exact and complete reproductions of a work. Many courts also use "substantial similarity" in place of "probative" or "striking similarity" to describe the level of similarity necessary to prove that copying has occurred. A number of tests have been devised by courts to determine substantial similarity. They may rely on expert or lay observation or both and may subjectively judge the feel of a work or critically analyze its elements.
Initial interest confusion is a legal doctrine under trademark law that permits a finding of infringement when there is temporary confusion that is dispelled before the purchase is made. Generally, trademark infringement is based on the likelihood of confusion for a consumer in the marketplace. This likelihood is typically determined using a multi-factor test that includes factors like the strength of the mark and evidence of any actual confusion. However, trademark infringement that relies on Initial interest confusion does not require a likelihood of confusion at the time of sale; the mark must only capture the consumer's initial attention.
Planned Parenthood Federation of America, Inc. v. Bucci, 1997 WL 133313, was a court ruling at the United States District Court for the Southern District of New York. The ruling was an important early precedent on the trademark value of a domain name on the World Wide Web, and established the theory that hosting a site under a domain name that was the registered trademark of a different party constituted trademark infringement.
Google, Inc. v. American Blind and Wallpaper Factory, Inc., No. 5:03-cv-05340, was a decision of the United States District Court for the Northern District of California that challenged the legality of Google's AdWords program. The court concluded that, pending the outcome of a jury trial, Google AdWords may be in violation of trademark law because it (1) allowed arbitrary advertisers to key their ads to American Blind's trademarks and (2) may confuse search-engine users initially interested in visiting American Blind's website into visiting its competitors' websites.
The case Brookfield Communications, Inc. v. West Coast Entertainment Corporation, 174 F.3d 1036, heard by the United States Court of Appeals for the Ninth Circuit, established that trademark infringement could occur through the use of trademarked terms in the HTML metatags of web pages when initial interest confusion was likely to result.
Lamparello v. Falwell, 420 F.3d 309, was a legal case heard by the United States Court of Appeals for the Fourth Circuit concerning allegations of cybersquatting and trademark infringement. The dispute centered on the right to use the domain name fallwell.com, and provides discussion on cybersquatting as it applies to criticism of a trademark.
Trademark infringement is a violation of the exclusive rights attached to a trademark without the authorization of the trademark owner or any licensees. Infringement may occur when one party, the "infringer", uses a trademark which is identical or confusingly similar to a trademark owned by another party, in relation to products or services which are identical or similar to the products or services which the registration covers. An owner of a trademark may commence civil legal proceedings against a party which infringes its registered trademark. In the United States, the Trademark Counterfeiting Act of 1984 criminalized the intentional trade in counterfeit goods and services.
Network Automation, Inc. v. Advanced Systems Concepts, Inc., 638 F.3d 1137 was a court case decided on March 8, 2011, where the United States Court of Appeals for the Ninth Circuit ruled that the use of a competitor's trademark as an Internet search advertising keyword did not constitute trademark infringement. In the case, Network Automation advertised their own competing product in search queries that contained Advanced Systems Concepts' "ActiveBatch" trademark. In determining whether trademark infringement occurred, the court evaluated factors relevant to the likelihood of customer confusion outlined in AMF Inc. v. Sleekcraft Boats and concluded that confusion was unlikely.
Consumer confusion is a state of mind that leads to consumers making imperfect purchasing decisions or lacking confidence in the correctness of their purchasing decisions.
Rosetta Stone v. Google, 676 F.3d 144 was a decision of the United States Court of Appeals for the Fourth Circuit that challenged the legality of Google's AdWords program. The Court overturned a grant of summary judgment for Google that had held Google AdWords was not a violation of trademark law.
Copyright protection is available to the creators of a range of works including literary, musical, dramatic and artistic works. Recognition of fictional characters as works eligible for copyright protection has come about with the understanding that characters can be separated from the original works they were embodied in and acquire a new life by featuring in subsequent works.
