Company name copy righted?

Company names are not copyrightable. They may be subject to the laws of trademark. Resolving a possible trademark dispute depends on knowledge of facts that you do not supply, such as who is the "senior" user, whether the name is the subject of a registration, the nature of the respective parties goods and services, and, most importantly, whether an appreciable number of ordinary consumers of the "junior" user's services are likely to be confused regarding whether those services are authorized or sponsored by the "senior" user. You will need to consult with a trademark attorney to discuss a resolution of this matter.
