The opinion of the court was delivered by: Milton I. Shadur Senior United States District Judge
This action has just been delivered to this Court's calendar via this District Court's random assignment system. Because of the regular (and entirely proper) reminders from our Court of Appeals that subject matter jurisdiction must be policed sua sponte (see, e.g, Wernsing v. Thompson, 423 F.3d 732, 743 (7th Cir. 2005)), this memorandum order is being issued contemporaneously with this Court's customary initial scheduling order, which will take effect only if the flaw identified here proves to be curable.
IDEX Corp., Eastern Plastics, Inc., Pulsafeeder, Inc. and Felice DiMascio have filed a Complaint for Declaratory Judgment, purporting to ground federal jurisdiction both (1) under the patent laws and (2) on asserted diversity of citizenship under 28 U.S.C. §1332.*fn1 Although the jurisdictional allegations in Complaint ¶3 also refer to the Declaratory Judgment Act, Sections 2201 and 2202, that statute is not of course a fount of federal jurisdiction, and hence it is disregarded for present purposes. And as for any claimed federal question jurisdiction, the Complaint is clearly not grounded in the patent statute--instead it simply seeks to enforce a Settlement Agreement under principles of issue preclusion: a common law claim.*fn2
That being the case, the identification of the parties' citizenship is defective because it speaks of the individual parties only in terms of their places of residence, not their respective states of citizenship (see Complaint ¶¶8 and 10). Under those circumstances our Court of Appeals teaches (Held v. Held, 137 F.3d 998, 1000 (7th Cir. 1998), quoting Guaranty Nat'l Title Co. v. J.E.G. Assocs., 101 F.3d 57, 59 (7th Cir. 1996):
Of course, allegations of residence are insufficient to establish diversity jurisdiction. It is well-settled that "[w]hen the parties allege residence but not citizenship, the court must dismiss the suit."
Nonetheless, on the assumption that the jurisdictional defect may be readily curable, this Court is loath to force on plaintiffs the payment of a second filing fee, which would be the consequence of complying with the literal teaching of Held. Accordingly plaintiffs' counsel is ordered to file an appropriate amendment to the Complaint on or before March 7, 2008, and as stated earlier this Court is issuing an initial scheduling order on the premise that the amendment will take care of the problem. In the meantime, however, plaintiffs' counsel should also accompany the corrective pleading with an explanation of why this action is being instituted in this judicial district rather than in the Texas forum in which the ...
