A trademark is a source-identified mark, used to communicate to the consumer the source, sponsorship, or origin of goods. A trademark is "any sign that individualizes the goods of a given enterprise and distinguishes them from the goods of its competitors." Trademarks typically constitute a name, word, phrase, design, logo, and/or commercial symbol used to identify products, services, or their producers in the marketplace. A trademark can be protected either on the basis of use or by registration, but in order to function, a trademark must be distinctive.

A plaintiff in a trademark infringement case must prove the likelihood of confusion as to the source of goods or services sold by the infringer. A variety of factors are considered in making this determination, including the strength of the plaintiff's mark, the similarity of the competing marks, the similarity of the goods or services offered, the similarity of the trade channels, the nature of similar marks in use on similar goods, and the extent of any actual customer confusion between the competing products or services.


International and domestic copyright laws protect the authors and creators of original works of authorship, assisting them in maintaining control and protecting the profits derived from their original work. Original works of authorship eligible for copyright protection include photographs, software, computer graphics and video games, jewelry and textile designs, musical compositions, paintings, movies, drawings, books, essays, works of art, lyrics, paintings, architectural works, and sculpture. A copyright grants exclusive legal ownership, including the right to copy and/or distribute.

Copyright law generally protects two types of rights. Economic rights protect the owner's right to derive financial reward from the use of the protected work by others. Moral rights allow the author the right to object to any distortion or modification of the protected work. Most copyright laws state that the author or rights owner has the right to authorize or prevent certain acts in relation to a work. For example, the rights owner of a work can prohibit or authorize:

  • The distribution of its copies;
  • Its reproduction in various forms;
  • Its public performance;
  • Its public broadcast;
  • Its translation; and
  • Its adaptation.

An original work of authorship is copyrighted at the time it is fixed to a tangible medium. These rights can be licensed, transferred, and/or assigned for a specific period of time. Registration is not required to own a copyright, but it may be advisable to register eligible work with the United States Copyright Office in order to better protect it. To prove copyright infringement, the owner of the original work must establish ownership and then prove that the work was copied. One key question in such disputes is the degree of similarity between the works.

Trade Secret Protection and Trade Dress

A trade secret constitutes valuable information, not available to the general public, that provides a competitive advantage to its owner. Trade secrets can be protected from trade secret misappropriation by a variety of contractual means, including employment agreements and policies, consultant agreements, independent contractor agreements, non-disclosure agreements, and manufacturing agreements. Resolution of disputes involving trade secrets and trade dress often depends heavily on the content of the specific contract at issue.
