Many companies, as well as private individuals, apply for and obtain online trademarks to protect themselves from infringement on the Internet. Online trademarks can offer an extra layer of protection in regard to unique items and other creative works. Many businesses in the 21st century operate entirely on the Internet, and their trademarked content can be viewed by millions of people all over the world. online trademarks are often stolen, copied, or unlawfully used by others online, either intentionally or by those unfamiliar with the laws regarding online trademarks. In many cases, contacting a person who has violated a trademark and explaining the trademark violation is all it takes to remedy a situation, however sometimes further action is needed, especially in the case of intentional trademark infringement. A cease and desist letter can be sent, and further legal action may be taken if needed. ISPs will also usually remove infringing content when notified.
