What is the purpose of a trademark?

A trademark serves to indicate the source of goods or services (in this post, I’ll refer to both goods and services collectively as “products” for simplicity).

A trademark may comprise words and/or logos used in connection with the sale of goods or services. In rare cases, a trademark may comprise a sound or three-dimensional product configuration.

Keep in mind that the offering of a product or service is key in making a word or graphic symbol a trademark. You cannot claim trademark rights by merely arguing that you coined a term if no products or services were ever provided.

What does “confusion” mean in the trademark world?

Since the purpose of a trademark is to indicate source, confusion refers to the notion that consumers encountering a particular trademark on a product may be led to believe that the product originates from the same source or has some sponsorship from the owner of a similar trademark.

Therefore, confusion in trademark vernacular has a special meaning that refers to two marks being so similar that consumers may be confused into thinking that the respective products originate from the same source [see TMEP § 1207.01].

Who would be confused?

Likelihood of confusion is determined from the perspective of the consumer. The level of sophistication of purchasers and the care in exercising a purchasing decision are factors to be considered [see TMEP § 1207.01(d)(vii)]. The tendency of applicants who receive a likelihood of confusion rejection is to reason why they (the business owner) would not be confused, but business owners are not the standard. Consumers are.

What’s the difference between likelihood of confusion and actual confusion?

Actual confusion refers to instances where consumers actually thought that the source of a product from Company B belonged to Company A. Examples may include a purchaser of a product from Company B calling Company A to ask a question or return the product.

When examining a trademark application, the USPTO examining attorney is making a determination on the likelihood of confusion, and not whether actual confusion exists.

What is a Section 2(d) refusal to register?

If you filed a federal trademark application with the USPTO, the examining attorney might issue a letter called an Office Action setting forth reasons why registration is refused. If likelihood of confusion is the reason, then the Office Action will contain a refusal under Section 2(d) which states: “No trademark by which the goods of the applicant may be distinguished from the goods of others shall be refused registration on the principal register on account of its nature unless it—

(d) Consists of or comprises a mark which so resembles a mark registered in the Patent and Trademark Office, or a mark or trade name previously used in the United States by another and not abandoned, as to be likely, when used on or in connection with the goods of the applicant, to cause confusion, or to cause mistake, or to deceive . . . .”

[15 USC § 1052(d)]

What are key factors in determining likelihood of confusion?

The du Pont factors are relevant considerations for making a determination on likelihood of confusion. The two most important factors are:

  • The similarity or dissimilarity of the marks in their entireties as to appearance, sound, connotation and commercial impression.
  • The relatedness of the goods or services as described in the application and registration(s).

[TMEP § 1207.01]

The greater the similarity between marks, the less related the goods or services have to be in order to support a finding of likelihood of confusion [see TMEP § 1207.01(a)]. Therefore, if two marks are identical or virtually identical, the respective goods or services need not be as close to find a likelihood of confusion.

The following remaining factors should be considered if applicable and relevant:

  • The similarity or dissimilarity of established, likely-to-continue trade channels.
  • The conditions under which and buyers to whom sales are made, i.e., “impulse” vs. careful, sophisticated purchasing [see TMEP §1207.01(d)(vii)].
  • The number and nature of similar marks in use on similar goods [see TMEP §1207.01(d)(iii)].
  • The existence of a valid consent agreement between the applicant and the owner of the previously registered mark [see TMEP §1207.01(d)(viii)].

Does likelihood of confusion require marks to be identical?

No, the standard is confusingly similar. Therefore, it’s possible for a new mark to be confusingly similar to a registered mark even if the new mark is not identical. Removing or changing certain portions of a registered mark will not guarantee that the new mark will be sufficiently distinguishable.

What if the same mark is used on different products?

The relatedness of the goods and/or services plays a key factor in determining likelihood of confusion. In general, the more similar your mark is to a registered mark, the less similar the products have to be to support a finding of likelihood of confusion [see TMEP § 1207.01(a)]. Keep in mind that goods can be related to services (e.g., food products and restaurant services), and that the relatedness of the products is not limited to a single trademark class.

What are examples of confusingly similar marks?

The USPTO has provided examples of confusingly similar marks based on sound, appearance, commercial impression and relatedness of goods and/or services here.
