Is it possible for a business to stop a person from having an email address similar to their companys name?

Without knowing all the details, it's hard to say but generally if a company has trademark or prior common-law rights to their name, then they will have the rights to enforce their rights.





But names are not protected "across the board;" certain parameters apply:





1) Are the names similar in Sound, Appearance or Meaning?





2) Are the industries the same or similar to one another?





3) Are the names confusingly similar to the average consumer? In other words, could customers be confused and assume that both companies are affiliated?





Here's what the USPTO has to say about this matter:





"The principal factors considered by the examining attorney in determining whether there would be a likelihood of confusion are:





the similarity of the marks; and


the commercial relationship between the goods and/or services listed in the application.





To find a conflict, the marks do not have to be identical, and the goods and/or services do not have to be the same. It may be enough that the marks are similar and the goods and/or services related."





It's best to contact a private search company or a trademark attorney to assist you in determining if this will be a problem or not.
