The law considers a trademark to be a form of property. Proprietary rights in relation to a trademark may be established through actual use in the marketplace, or through registration of the mark with the trademarks office (or "trademarks registry") of a particular jurisdiction. In some jurisdictions, trademark rights can be established through either or both means. Certain jurisdictions generally do not recognize trademarks rights arising through use. If trademark owners do not hold registrations for their marks in such jurisdictions, the extent to which they will be able to enforce their rights through trademark infringement proceedings will therefore be limited. In cases of dispute, this disparity of rights is often referred to as "first to file" as opposed to "first to use." Other countries such as Germany offer a limited amount of common law rights for unregistered marks where to gain protection, the goods or services must occupy a highly significant position in the marketplace — where this could be 40% or more market share for sales in the particular class of goods or services.
In the United States the registration process entails several steps prior to a trademark receiving its Certificate of Registration. First, an Applicant, the individual or entity applying for the registration, files an application to register the respective trademark. The application is then placed in line in the order it was received to be examined by an examining attorney for the U.S. Patent and Trademark Office. Second, following a period of anywhere from three to six months the application is reviewed by an examining attorney to make sure that it complies with all requirements in order to be entitled to registration. This review includes procedural matters such as making sure the applicant's goods or services are identified properly. It also includes more substantive matters such as making sure the applicant's mark is not merely descriptive or likely to cause confusion with a pre-existing applied-for or registered mark. If the application runs afoul of any requirement, the examining attorney will issue an office action requiring the applicant to address certain issues or refusals prior to registration of the mark. Third, and after the examination of the mark has concluded with no issues to be addressed or an applicant has responded adequately to an examining attorney's concerns, the application will be published for opposition. During this 30-day period third-parties who may be affected by the registration of the trademark may step forward to file an Opposition Proceeding to stop the registration of the mark. If an Opposition proceeding is filed it institutes a case before the Trademark Trial and Appeal Board to determine both the validity of the grounds for the opposition as well as the ability of the applicant to register the mark at issue. Fourth, provided that no third-party opposes the registration of the mark during the opposition period or the opposition is ultimately decided in the applicant's favor the mark will be registered in due course.
Outside of the United States the registration process is substantially similar to that found in the U.S. save for one notable exception in many countries: registration occurs prior to the opposition proceeding. In short, once an application is reviewed by an examiner and found to be entitled to registration a registration certificate is issued subject to the mark being open to opposition for a period of typically 6 months from the date of registration.
A registered trademark confers a bundle of exclusive rights upon the registered owner, including the right to exclusive use of the mark in relation to the products or services for which it is registered. The law in most jurisdictions also allows the owner of a registered trademark to prevent unauthorized use of the mark in relation to products or services which are identical or "colourfully" similar to the "registered" products or services, and in certain cases, prevent use in relation to entirely dissimilar products or services. The test is always whether a consumer of the goods or services will be confused as to the identity of the source or origin. An example may be a very large multinational brand such as "Sony" where a non-electronic product such as a pair of sunglasses might be assumed to have come from Sony Corporation of Japan despite not being a class of goods that Sony has rights in.
Once trademark rights are established in a particular jurisdiction, these rights are generally only enforceable in that jurisdiction, a quality which is sometimes known as territoriality. However, there is a range of international trademark laws and systems which facilitate the protection of trademarks in more than one jurisdiction (see International trademark laws below).
