No, you cannot directly trademark a web domain itself. Trademarks are intended to protect distinctive signs or symbols used to identify and distinguish goods or services in the marketplace. A web domain, on the other hand, is a unique address used to locate and access a website on the internet.
However, you can incorporate your web domain into a trademark application if it is used as part of your brand identity or as a way to distinguish your goods or services. In such cases, the web domain can be considered as a component of the overall trademark. For example, if your brand name is "XYZ" and your web domain is "xyz.com," you can include the web domain as part of your trademark application to protect the overall brand.
