(a) A lawyer may communicate the fact that the lawyer does or does not practice in particular fields of law. (b) A lawyer admitted to engage in patent practice before the United States Patent and Trademark Office may use the designation “Patent Attorney” or a substantially similar designation. (c) A lawyer engaged in Admiralty practice may use the designation “Admiralty,” “Proctor in Admiralty” or a substantially similar designation. (d) A lawyer shall not state or imply that a lawyer is certified as a specialist in a particular field of law, unless: (1) the lawyer has been certified as a specialist by an organization that has been approved by an appropriate state authority or that has been accredited by the American Bar Association; and (2) the name of the certifying organization is clearly identified in the communication. [History: Am. (b), (c), and (d) effective July 1, 2007.] Comment  Paragraph (a) of this Rule permits a lawyer to indicate areas of practice in communications about the lawyer’s services; for example, in a telephone directory or other advertising. If a lawyer practices only in certain fields, or will not accept matters except in such fields, the lawyer is permitted so to indicate. However, stating that the lawyer is a “specialist” is not permitted. This term has acquired a secondary meaning implying formal recognition as a specialist. Hence, use of this term may be misleading unless the lawyer is certified or recognized in accordance with procedures in the state where the lawyer is licensed to practice.  Paragraph (b) recognizes the long-established policy of the Patent and Trademark Office for the designation of lawyers practicing before the Office. Paragraph (c) recognizes that designation of Admiralty practice has a long historical tradition associated with maritime commerce and federal courts.  Paragraph (d) permits a lawyer to state that the lawyer is certified as a specialist in a field of law if such certification is granted by an organization approved by an appropriate state authority or accredited by the American Bar Association or another organization, such as a state bar association, that has been approved by the state authority to accredit organizations that certify lawyers as specialists. Certification signifies that an objective entity has recognized an advanced degree of knowledge and experience in the specialty area greater than is suggested by general licensure to practice law. Certifying organizations may be expected to apply standards of experience, knowledge and proficiency to insure that a lawyer’s recognition as a specialist is meaningful and reliable. In order to insure that consumers can obtain access to useful information about an organization granting certification, the name of the certifying organization must be included in any communication regarding the certification.
