What is the punctuation requirement for serial and registration numbers?

The requirement for serial and registration numbers in trademark applications is that they must be presented without any punctuation, specifically separated only by a space. This format ensures clarity and consistency in how these numbers are recorded and accessed within the USPTO database.

Using a space without other punctuation elements helps to avoid confusion that could arise from using commas, semicolons, or dashes, which may suggest a different relationship among the numbers. This standard formatting rule aids in streamlining the evaluation process of applications and ensures that the information can be accurately processed by the USPTO's systems.

Other punctuation choices like commas or semicolons could lead to misinterpretation, as they are typically used in lists or to separate items, which doesn't apply in the case of submitting serial and registration numbers. Grouping with dashes might imply a different structure or relationship that is not intended in this context. Hence, the clarity of presenting these numbers solely separated by a space is essential for proper identification and processing.
