WHAT IS TRADEMARK INFRINGEMENT?

Section 2(d) of the Trademark Act requires that the examining attorney refuse registration when an applicant’s mark, as applied to the specified goods or services, so resembles a registered mark as to be likely to cause confusion. In general, registration of confusingly similar marks to separate legal entities is barred by §2(d).  However, the Court of Appeals for the Federal Circuit has held that, where the applicant is related in ownership to a company that owns a registered mark that would otherwise give rise to a likelihood of confusion, the examining attorney must consider whether, in view of all the circumstances, use of the mark by the applicant is likely to confuse the public about the source of the applicant’s goods because of the resemblance of the applicant’s mark to the mark of the other company. A determination must be made as to whether there exists a likelihood of confusion as to source, that is, whether purchasers would believe that particular goods or services emanate from a single source, when in fact those goods or services emanate from more than a single source.
