Just because the applicant is conducting an activity that may involve transmission of data on the Internet does not mean the applicant’s service is a Class 38 service. For example, an applicant who merely has a website is not conducting “electronic transmission of messages and data,” in Class 38. The companies providing the Internet connections are conducting the actual transmissions; the applicant is merely making the information available.

“Online bulletin boards” and “chat rooms” are classified in Class 38 regardless of the content or subject matter. The rationale for this stems from the fact that these services allow individuals to communicate with each other, like other Class 38 services.
