In Ohio, the attorney-client privilege is governed by R.C. 2317.02(A), which provides that an attorney shall not testify "concerning a communication made to the attorney by a client in that relation or the attorney's advice to a client." State v. McDermott (1995), 72 Ohio St.3d 570, 574, 1995 Ohio 80, 651 N.E.2d 985. Knowledge gained by an attorney, during the attorney-client relationship, which knowledge relates to the services for which he was employed, whether it be by words or merely by observations made by the attorney, falls within the rule relating to privileged communications.
