1202.16(c)(i)(A) Model Designations
To support a refusal to register a model designation for failure to function as a mark, the examining attorney must use the applicant’s specimen, along with any other relevant evidence in the application, such as the identification of goods and mark description. If available, the examining attorney should also provide additional evidence that shows that the proposed mark would be perceived merely as a model designation, such as consumers referring to the applicant’s proposed mark as a model or part number when ordering the goods. Evidence that other manufacturers use similar numbering systems to identify model numbers for their goods may be submitted to show that consumers are familiar with the use of alphanumeric designations as model numbers and are consequently less likely to perceive the applicant’s use of the mark as source indicating.
