A trademark serves multiple purposes, including protecting the identity of a brand, preventing others from using the same or similar mark, and indicating the source of goods or services.

In the United States, trademark rights can be acquired either through use or through registration. Use alone can establish common law trademark rights, while registration with the United States Patent and Trademark Office (USPTO) provides nationwide protection and additional benefits.

A trademark is a distinctive sign that identifies goods, while a service mark is a distinctive sign that identifies services. Both trademarks and service marks can be registered with the USPTO, and both provide nationwide protection.

In order to obtain a trademark registration, the mark must be distinctive, used in commerce, and not confusingly similar to any other mark.

A trademark registration lasts for 10 years from the date of registration. It can be renewed for additional 10-year periods as long as the mark is still in use and the renewal fees are paid.

Failing to maintain a trademark registration can have several consequences, including the mark becoming generic, being infringed by others, and being canceled by the USPTO.

A trademark is a distinctive sign that identifies goods, while a trade name is a distinctive sign that identifies a business. Both trademarks and trade names can be registered with the USPTO, and both provide nationwide protection.
