i have an idea for a business name and have performed an initial search using the following resources: internet (extensively), uspto database, county dba databases.

the only conflict i have found is a company with a similar name, located in the uk. this business also owns www.[thebusinessname].co.uk. they are in the same industry but offer different services. for example, i offer consulting they offer make-up services.

should i let this prevent me from using the business name?

also: there is no registered trademark for that business and again it is located in the uk, i am in california.
