Summary
Explains benefits of registering a trademark
In the United States at least, registration is not a requirement for trademark protection, because trademark rights exist when a trademark is used in connection with the sale of goods and services. If that is the case, then why register?
One good reason is that it allows a brand to expand across the country more easily. Without a registration, the business may not be able to stop imitators in other parts of the country where the business has not actually begun using the trademark.
Registering your trademark also makes it visible to anyone with a web browser who can access the Trademark Office search page. Many new businesses will conduct trademark searches before deciding to use a new brand, and if they see a similar trademark that is already registered, they may choose something else, avoiding the issue before a conflict arises.
