Goods and Services

Goods are products.

In the context of service marks, a service (1) must be a real activity; (2) must be performed to the order of, or for the benefit of, someone other than the applicant; and (3) the activity performed must be qualitatively different from anything necessarily done in connection with the sale of the applicant's goods or the performance of another service.
