Chicago Bd. Options Exchange Inc. v. Realtime Data, LLC d/b/a IXO, No. 09 C 4486, Slip. Op. (N.D. Ill. Jan. 8, 2009) (Lindberg, Sen. J.).

Judge Lindberg granted declaratory judgment for defendant Realtime’s Fed. R. Civ. P. 12(b)(2) motion to dismiss for lack of personal jurisdiction. The parties agreed that the Court lacked general jurisdiction and focused their arguments on specific jurisdiction. Because plaintiff Chicago Board Options Exchange ("CBOE") brought declaratory judgment claims, the analysis focused upon whether Realtime’s patent enforcement activities were directed at the jurisdiction. CBOE argued that specific jurisdiction was created by Realtime’s Texas patent infringement suit against, among others, Chicago-based defendants, including eventually CBOE. But the Court held that Realtime’s Texas action alone did not create specific jurisdiction, and the Court did not consider the Texas suit against CBOE because CBOE was not added to the Texas action until after the instant suit was filed.
