In order to protect as well as enhance a company's identity, a trademark is often registered. Trademarks can be used for company names, logos, slogans, or unique images that identify the company. In the event that a third party unlawfully uses a trademarked item, the trademark holder is protected by law and may be able to pursue legal action to stop the unlawful use. A trademark holder may also be able to gain monetary damages in the event of a trademark violation. Many people choose to register a trademark online in order to protect their intellectual property. Online services are available to help with the trademark application process; generally companies charge fees to help register a trademark online, in addition to the filing fee. A trademark search is also often used before attempting to register a trademark online. A trademark search is used to check the availability of a trademark. If an item has already been trademarked, a trademark search will uncover this.
