Likelihood of Confusion

As discussed in a much earlier post, it is important to select a strong trademark. The purpose of a trademark is to distinguish an owner’s goods and services from another’s goods or services. Since the purpose of a trademark is to act as a source indicator, it is important that two trademarks are not so similar, that the consuming public believes them to be related, or confuses them, this is known as likelihood of confusion. Under §2(d) of the Lanham Act, marks that are found to be confusingly similar are unregistrable with the USPTO.

When determining likelihood of confusion, the key factors an examining attorney relies on are known as the Dupont Factors. The two most important factors to consider are: (1) The similarity or dissimilarity of the marks in their entireties as to appearance, sound, connotation and commercial impression. (2) The relatedness of the goods or services as described in the application and registration(s).  When looking at these two factors, the order in which they are considered is important, because the more similar the marks are, the less related the goods or services need to be in order to support a finding of likelihood of confusion.  The following are the remaining seven factors that should be considered if applicable and relevant: (3) The similarity of established, likely-to-continue trade channels. (4) The conditions under which and buyers to whom sales are made, i.e., “impulse” vs. careful, sophisticated purchasing. (5) The number and nature of similar marks in use on similar goods. (6) The existence of a valid consent agreement between the applicant and the owner of the previously registered mark. (7) Fame of the prior mark. (8) Nature and extent of any actual confusion. (9) Concurrent use without evidence of actual confusion: length of time and conditions. It is important to note that not all of these factors will be applicable in every case.

When determining likelihood of confusion, the standard is confusingly similar. Two marks need not be identical to support a finding of likelihood of confusion. This means that a new mark may be confusingly similar to a previously registered mark even if it is not identical. There is no guarantee that changing or removing portions of a new mark will make it sufficiently distinguishable and therefore registrable with the USPTO.
