37 CFR 350.2 - Representation.
Individual parties in proceedings before the Judges may represent themselves or be represented by an attorney. All other parties must be represented by an attorney. Cf. Rule 49(c)(11) of the Rules of the District of Columbia Court of Appeals. The appearance of an attorney on behalf of any party constitutes a representation that the attorney is a member of the bar, in one or more states, in good standing.
