In Estate of Poole v. Grosser, (1999), 134 Ohio App.3d 386, 731 N.E.2d 226, the Court held that Kentucky doctors and a Kentucky hospital had not engaged in the sort of regular, continuous activity required to justify an Ohio court in assuming jurisdiction, when they had taken out listings in Ohio phone books, sent a brochure to Ohio, and maintained a few advertisements in Ohio. Poole, supra, at 391-394. Poole did not involve R.C. 2307.382(A)(1), the transacting-business section of the long-arm statute. Instead, it involved R.C. 2307.382(A)(4), which allows an Ohio court to exercise jurisdiction over "any person causing tortious injury in this state by an act or omission outside this state if he regularly does or solicits business, or engages in any other persistent course of conduct, or derives substantial revenue from goods used or services rendered in this state."
