John Tamburo, an Illinois resident who operates a dog-breeding software business in Illinois, filed suit in the Northern District of Illinois alleging federal and state antitrust violations and several intentional tort claims under Illinois law. His claims arise out of a dispute over the contents of a dog-pedigree software program he developed by lifting data from the defendants’ websites. He alleges the defendants used the Internet to retaliate against him for copying their online data, which he contends was in the public domain. The defendants are a Canadian proprietor of a dog-pedigree website who has never visited or transacted business in Illinois; three Americans who likewise maintain dog-pedigree websites and are residents of Colorado, Michigan, and Ohio with only sporadic contacts with Illinois; and an Australian software company with insignificant sales in Illinois. This appeal requires us to apply long-established rules for asserting personal jurisdiction over foreign defendants to the relatively new setting of torts committed over the Internet.
Tamburo alleges that the individual Canadian and American defendants engaged in a concerted campaign of blast emails and postings on their websites accusing him of stealing their data and urging dog enthusiasts to boycott his products. He also claims they sent some of these messages to the owner of the Australian company, who reposted them to a private dog-breeder listserve. These emails and Internet postings, Tamburo claims, violate federal and state antitrust laws, were defamatory and tortiously interfered with his software business, and constituted a civil conspiracy to boot. The defendants moved to dismiss for lack of personal jurisdiction and alternatively for failure to state a claim. The district court dismissed the case against all defendants for lack of personal jurisdiction.
We affirm in part and reverse in part. First, Tamburo’s federal and state antitrust allegations are woefully inadequate under
Bell Atlantic Corp. v. Twombly,
Applying
Calder v. Jones,
I. Background 1
John Tamburo, doing business as Man’s Best Friend Software, lives and operates his business in Illinois. He designs software for use by dog breeders and noncommercial dog enthusiasts. 2 One of his products, an online database called The Breeder’s Standard, provides customers with access to dog-pedigree information. To create the database, Tamburo developed an automated computer program that scanned the Internet for information about dog pedigrees. He then incorporated the data he retrieved into The Breeder’s Standard.
Defendants Kristen Henry, Roxanne Hayes, Karen Mills, and Steven Dworkin are proprietors of public websites that provide free access to dog-pedigree information. Henry, a Colorado citizen and resident, also breeds and shows dogs. Hayes, a Michigan citizen and resident, raises, shows, and “places” dogs but does not commercially breed them. Mills, a citizen and resident of Ohio, raises and shows dogs. Dworkin, a Canadian citizen who resides in Ottowa, also raises and shows dogs. 3
Tamburo pulled much of the information included in The Breeder’s Standard from the websites operated by Henry, Hayes, Mills, and Dworkin. In retaliation Henry, Hayes, and Mills posted statements on their websites accusing Tamburo of “theft,” “hacking,” and “selling stolen goods,” and calling on readers to boycott his products. They also posted Tamburo’s Illinois address on their websites and urged readers to contact him to harass him and otherwise complain. Dworkin retaliated in a different way. First, he emailed Tamburo and demanded that he remove the “blatent [sic] theft of data” from The Breeder’s Standard “within 5 days.” If Tamburo failed to do so, Dworkin threatened to “publish to each and every dog[-]based list the sleazy methods” of Tamburo’s operation. When Tamburo did not comply, Dworkin emailed “all persons who had a free online database of dog pedigrees on the Internet” saying that Tamburo’s product contained pedigree data that was “stolen,” “mined,” and “harvested” for improper “commercial use,” and suggested that all proprietors of online dog-pedigree databases “band together to stop this theft” of their data.
The fifth defendant is Wild Systems Pty Ltd., an Australian software company that offers a pedigree software program called Breedmate. Wild Systems also runs a private online Yahoo! email listserve for customers who have purchased the Breed-mate software. Ronald DeJong, the owner and president of Wild Systems, manages this email list and must approve any message sent to it. The individual defendants sent DeJong messages for posting on the Breedmate listserve; these messages, like the others, protested that Tamburo had stolen their data. DeJong in turn transmitted these messages to the Breedmate listserve. Later, DeJong and *699 the individual defendants organized a closed Internet chat group — called the “APDUG Group” 4 — for users of Alfirin software, a product used to manage dog-pedigree databases. In messages posted to the APDUG Group, the individual defendants again accused Tamburo of “theft,” “selling stolen goods,” and “hacking.”
Tamburo sued the five defendants in the Northern District of Illinois, seeking a declaratory judgment that he did not violate any federal law by incorporating the defendants’ databases into his software. He also sought damages for federal and state antitrust violations and asserted claims for defamation, tortious interference with existing contracts and prospective economic advantage, trade libel, and civil conspiracy under Illinois law. 5
The defendants moved to dismiss the complaint for lack of personal jurisdiction and failure to state a claim. See Fed. R.Civ.P. 12(b)(2), 12(b)(6). The district court concluded that personal jurisdiction was lacking as to all defendants and dismissed the case without considering the alternative failure-to-state-a-claim arguments. Tamburo moved for reconsideration, asking the court to transfer the case to the Western District of Michigan. This motion was denied and Tamburo appealed.
II. Discussion
A. Antitrust Claims
In
Bell Atlantic Corp. v. Twombly,
Tamburo’s antitrust claims are pleaded in a wholly conclusory fashion; as such, it is hard to tell what kind of antitrust violation he is trying to assert. The complaint contains no factual allegations suggesting the existence of an antitrust conspiracy or an antitrust injury. The federal claim alleges only that the defendants possessed “monopoly power in the relevant market of dog breeding data,” which they acquired “by means of anticompetitive and/or predatory conduct,” and that this “violated provisions of Federal Antitrust statutes including 15 U.S.C. [§§ ] 1, et seq.” This appears to sweep in the entire gamut of federal antitrust viola *700 tions, but there are no allegations whatsoever regarding an antitrust injury. The complaint alleges only that Tamburo “has been damaged” as a result of “the wrongful acts of Defendants.” This manner of pleading a federal antitrust claim is plainly improper under Twombly.
Tamburo’s attempt to plead a state-law antitrust violation fares no better. The complaint asserts a claim under the Illinois Antitrust Act, 740 III. Comp. Stat. 10/1
et seq.,
which parallels the federal Sherman and Clayton Acts. But this section of the complaint simply repeats the inadequate allegations contained in the federal antitrust claim. Because federal pleading standards apply when we sit in diversity,
Windy City Metal Fabricators & Supply, Inc. v. CIT Tech. Fin. Servs., Inc.,
B. Personal Jurisdiction
We review a dismissal for lack of personal jurisdiction de novo.
GCIU-Employer Ret. Fund v. Goldfarb Corp.,
Where no federal statute authorizes nationwide service of process,
6
personal jurisdiction is governed by the law of the forum state. FED. R. CIV. P. 4(k)(l)(A);
see also Citadel Group Ltd. v. Wash. Reg’l Med. Ctr.,
Stated differently, each defendant must have purposely established minimum contacts with the forum state such that he or she “should reasonably anticipate being haled into court” there.
Burger King Corp. v. Rudzewicz,
1. General Personal Jurisdiction
The nature of the defendant’s contacts with the forum state determines the propriety of personal jurisdiction and also its scope — that is, whether jurisdiction is proper at all, and if so, whether it is general or specific to the claims made in the case. A defendant with “continuous and systematic” contacts with a state is subject to general jurisdiction there in any action, even if the action is unrelated to those contacts.
Helicopteros Nacionales de Colombia, S.A. v. Hall,
Illinois cannot exercise general personal jurisdiction over any of the defendants in this case. Henry has been to Illinois only twice in ten years. Hayes has been to Illinois approximately 5 times and has placed 13 dogs with families in Illinois but did not receive any profits from these placements. She sold three copies of her book to individuals in Illinois through her website. Mills grew up in Illinois but moved away in 1979 and has only traveled back twice since then. Dworkin, the Canadian defendant, has never “been to, stopped in or passed through” Illinois. Each of the individual defendants maintains a public website obviously accessible by Illinois residents, but as we have noted, that is not enough to establish general personal jurisdiction. Finally, Wild Systems, the corporate defendant, is an Australian company located in New South Wales, Australia. It has no offices in Illinois (or anywhere in the United States, for that matter), nor has it ever had a distributor in Illinois. Since it was incorporated in 1996, Wild Systems has had a total of $8,634 in sales to customers in Illinois. These sporadic contacts with Illinois do not approach the level of “continuous and *702 systematic” contacts necessary to establish general personal jurisdiction.
2. Specific Personal Jurisdiction
The question of specific personal jurisdiction is much more difficult. To support an exercise of specific personal jurisdiction, the defendant’s contacts with the forum state must directly relate to the challenged conduct or transaction; we therefore evaluate specific personal jurisdiction by reference to the particular conduct underlying the claims made in the lawsuit.
See GCIU-Employer Ret. Fund,
a. Conduct “purposefully directed” at the forum state
The purposeful-direction inquiry “can appear in different guises.”
Dudnikov v. Chalk & Vermilion Fine Arts, Inc.,
The Supreme Court’s decision in
Calder
provides some contours for the “purposeful direction” requirement in the context of a suit alleging intentional torts.
Calder
gave significant weight to the “effects” of a foreign defendant’s conduct within the forum state. In
Calder
actress Shirley Jones — star of movie musicals and the 1970s television show
The Partridge Family
— filed suit in California against the
National Enquirer,
its local distributor, and the writer and editor of an allegedly libelous article that appeared in the
Enquirer.
Petitioner South wrote and petitioner Calder edited an article that they knew would have a potentially devastating im *703 pact upon [Jones]. And they knew that the brunt of that injury would be felt by respondent in the State in which she lives and works and in which the National Enquirer has its largest circulation. Under these circumstances, petitioners must reasonably anticipate being haled into court there to answer for the truth of the statements made in their article. An individual injured in California need not go to Florida to seek redress from persons who, though remaining in Florida, knowingly cause[d] the injury in California.
Id.
at 789-90,
Calder
thus suggests three requirements for personal jurisdiction in this context: (1) intentional conduct (or “intentional and allegedly tortious” conduct); (2) expressly aimed at the forum state; (3) with the defendant’s knowledge that the effects would be felt — that is, the plaintiff would be injured — in the forum state.
See Dudnikov,
*704 1. “Intentional” acts or “intentional and allegedly tortious” acts
The circuits are divided over whether
Calder’s
“express aiming” inquiry includes
all
jurisdictionally relevant intentional acts of the defendant or only those acts that are intentional
and
alleged to be tortious or otherwise wrongful.
Compare Marten v. Godwin,
2. “Express aiming” and knowledge that plaintiff would be injured in forum state
In
Calder
the Supreme Court emphasized that the defendants were not “charged with mere untargeted negligence,” but instead had “expressly aimed” their alleged libel at California, where they knew Jones lived and worked and would suffer the “brunt of th[e] injury.”
Some circuits have read
Calder’s
“express aiming” requirement fairly broadly, requiring only conduct that is “targeted at a plaintiff whom the defendant knows to be a resident of the forum state.”
Bancroft & Masters, Inc. v. Augusta Nat’l Inc.,
In
Wallace
the question was whether Indiana could exercise jurisdiction over California defendants who were sued by an Indiana resident for malicious prosecution when the allegedly tortious conduct occurred exclusively in California. Applying
Calder,
we held that jurisdiction was not
*705
proper in Indiana; in so holding we focused on the relationship between the defendants’ actions and the forum state itself, not just on the relationship between those actions and the plaintiffs injury.
Janmark
took a broader view of
Calder.
There, shopping-cart competitors Janmark and Dreamkeeper sold mini shopping carts throughout the United States — Dream-keeper from California and Janmark from Illinois.
Another case — one specifically relied on in
Janmark
— is also instructive here.
Indianapolis Colts, Inc. v. Metropolitan Baltimore Football Club Ltd. Partnership,
Janmark
is hard to reconcile with
Wallace
and to a lesser extent, with
Indianapolis Colts
— at least if
Janmark
is understood as broadly authorizing personal jurisdiction wherever a tort victim is injured.
8
Both
Wallace
and
Indianapolis
*706
Colts
read
Colder
to require a forum-state injury
and
“something more” directed at that state before jurisdiction over a foreign defendant may be considered proper. Importantly, however, the holding in
Jan-mark
ultimately focused on more than the fact that the injury had occurred in Illinois;
Janmark’s
jurisdictional conclusion was premised on the Illinois-based injury
and
the fact that the defendant acted with the purpose of interfering with sales originating in Illinois. Thus, despite its broad language about
Colder, Janmark
ultimately considered the relationship between the allegedly tortious conduct and the forum state itself.
See Nerds on Call, Inc. (Indiana) v. Nerds on Call, Inc. (California),
This case involves both a forum-state injury and tortious conduct specifically directed at the forum, making the forum state the focal point of the tort — at least with respect to the individual defendants. (We will discuss the corporate defendant in a moment.) Moreover, if the cable-television broadcasts of Baltimore Colts football games could be considered an electronic “entry” into Indiana for purposes of personal jurisdiction in Indianapolis Colts, then the individual defendants’ use of their public websites to defame an Illinois-based businessman and exhort readers to boycott his products can likewise be conceptualized as an electronic “entry” into Illinois for jurisdictional purposes.
More specifically, Dworkin, Henry, Hayes, and Mills are each alleged to have published false and defamatory statements about Tamburo, either on their public websites or in blast emails to other proprietors of online dog-pedigree databases. In some of these messages, readers were encouraged to boycott Tamburo’s products; in others, Tamburo’s Illinois address was supplied and readers were urged to contact and harass him. The complaint also alleges that Dworkin personally contacted Tamburo by email, accusing him of “theft” and demanding that he remove the “stolen” data from The Breeder’s Standard. Dworkin threatened to expose Tamburo’s “theft” to the online dog-pedigree community if he did not comply. Dworkin, Henry, Hayes, and Mills engaged in this conduct with the knowledge that Tamburo lived in Illinois and operated his business there; their affidavits do not deny this. Thus, although they acted from points outside the forum state, these defendants specifically aimed their tortious conduct at Tamburo and his business in Illinois with the knowledge that he lived, worked, and would suffer the “brunt of the injury” there. 9 These allegations suffice to establish personal jurisdiction over these defendants under either a broad or a more restrictive view of Colder.
The Tenth Circuit’s decision in
Dudnikov
supports this conclusion. In
Dudnikov
a Connecticut-based company notified
*707
the online auction host eBay, based in California, that a line of prints featured in an eBay auction infringed its copyright. eBay responded by cancelling the auction for the prints. The online sellers of the prints lived and operated their business in Colorado; they filed a copyright suit in Colorado against the Connecticut-based company. The district court dismissed the case for lack of personal jurisdiction.
[The defendant’s conduct] is something like a bank shot in basketball. A player who shoots the ball off of the backboard intends to hit the backboard, but he does so in the service of his further intention of putting the ball into the basket. Here, defendants intended to send the [copyright notice] to eBay in California, but they did so with the ultimate purpose of cancelling plaintiffs’ auction in Colorado. Their “express aim” thus can be said to have reached into Colorado in much the same way that a basketball player’s express aim in shooting off of the backboard is not simply to hit the backboard, but to make a basket.
Id.
Although the circumstances here are not easily analogized to a basketball bank shot, we take the Tenth Circuit’s point and agree with its analysis. Here, the individual defendants purposely targeted Tamburo and his business in Illinois with the express goal of inflicting commercial and reputational harm on him there, even though their alleged defamatory and otherwise tortious statements were circulated more diffusely across the Internet.
10
Tortious acts aimed at a target in the forum state and undertaken for the express purpose of causing injury there are sufficient to satisfy
Calder’s
express-aiming requirement.
See Dudnikov,
The same is not true, however, of Wild Systems, the Australian corporate defendant. Recall that DeJong, the owner and president of Wild Systems, allegedly facilitated the posting of some of the individual defendants’ tortious messages on the company’s private Breedmate Yahoo! email listserve. The complaint does not say how many, nor does it describe the content of the messages that were reposted onto the listserve. It does not allege, for example, that DeJong reposted emails specifically calling for a boycott of Tamburo’s Illinois-based business. And unlike the individual defendants, there are no allegations that DeJong or anyone else associated with Wild Systems acted with the knowledge that Tamburo operated his business in Illinois or with the specific purpose of inflicting injury there. In short, we cannot conclude that DeJong’s reposting of an unspecified number of messages of unspecified (but tortious) content to a private listserve of unspecified scope and reach is enough to establish that Wild Systems “expressly aimed” its allegedly tortious conduct at Illinois. As such, the claims against Wild Systems were properly dismissed for lack of personal jurisdiction.
b. Injury “arises out of’ the defendants’ contacts with forum state
Our conclusion that the individual defendants’ conduct was “purposely directed” at the forum state does not end the jurisdictional inquiry. Tamburo’s injury must “arise out of’ or “relate to” the conduct that comprises the defendants’ contacts with the forum.
See Burger King,
The First Circuit has held that at least with respect to intentional tort claims, the defendant’s contacts with the forum must constitute both the cause in fact and the proximate cause of the injury.
Mass. Sch. of Law at Andover, Inc. v. Am. Bar Ass’n,
The Third Circuit has taken a middle-ground approach, holding that “specific jurisdiction requires a closer and more direct causal connection than that provided by the but-for test,” but has not adopted a precise rule, opting instead to proceed on a case-by-case basis.
O’Connor v. Sandy Lane Hotel Co.,
We have not weighed in on this conflict and need not do so here.
12
Under even the most rigorous approach to the determination of whether the plaintiffs injury “arises out of’ the defendant’s contacts with the forum state, Tamburo’s injury clearly does. We have already concluded that Dworkin, Henry, Hayes, and Mills expressly aimed their allegedly tortious conduct at Tamburo and his Illinois-based business for the purpose of causing him injury there; these “contacts” with the forum state are the cause in fact and the legal cause of Tamburo’s injury. That is, Tamburo’s claims arise directly out of the individual defendants’ contacts with Illinois.
See RAR,
c. Traditional notions of fair play and substantial justice
Our final inquiry is whether Illinois’ exercise of personal jurisdiction over Dworkin, Henry, Hayes, and Mills would offend traditional notions of fair play and substantial justice.
See Int'l Shoe,
First, Illinois has a strong interest in providing a forum for its residents and local businesses to seek redress for tort injuries suffered within the state and inflicted by out-of-state actors. Although Tamburo could have sued the individual defendants in their home jurisdictions, that would have been cumbersome and impractical; the American defendants live in separate states and Dworkin lives in Canada. Neither Canada nor any of the states where the American defendants live (Colorado, Michigan, or Ohio) has a substantial interest at stake here. And it would be unreasonable to expect Tamburo to file separate lawsuits to give each defendant the privilege of defending this litigation in his or her home state when jurisdiction is otherwise proper in Illinois. Under these circumstances, it is far more reasonable to conclude that the defendants should anticipate being haled into court in Tamburo’s
*710
home state of Illinois than a court in a codefendant’s home jurisdiction. A single suit in Illinois also promotes the most efficient resolution of these claims.
See Logan Prods., Inc. v. Optibase, Inc.,
For the foregoing reasons, we Affirm the district court’s order dismissing all counts against Wild Systems for lack of personal jurisdiction and also Affirm the dismissal of the antitrust claims against all defendants for failure to state a claim. We Reverse the district court’s order dismissing the state-law tort claims against Dworkin, Henry, Hayes, and Mills for lack of personal jurisdiction and Remand the case for further proceedings.
Notes
. Because this case comes to us from a jurisdictional dismissal on the pleadings, we take the factual background from the Sixth Amended Complaint, and where not contradictory, from affidavits submitted by the parties in connection with their motion to dismiss.
. Tamburo was also the president and sole shareholder of Versity Corporation, the other plaintiff in this suit. Versity dissolved in May 2004 just before this lawsuit was filed and appears as a plaintiff by virtue of 805 III. Comp. Stat. 5/12.80, the Illinois statute authorizing postdissolution survival of actions.
. Dworkin died during the pendency of this appeal; defendants’ counsel represents his estate.
. ''APDUG” stands for Alfirin Pedigree Database Users Group.
. Tamburo estimates he lost over $525,000 in sales as a result of the defendants’ conduct.
. Tamburo argues that nationwide service of process was authorized pursuant to Rule 4(k)(l)(c) of the Federal Rules of Civil Procedure, together with § 22 of the Clayton Act, 15 U.S.C. § 22, or alternatively, under Rule 4(k)(2). Both jurisdictional bases, however, require a claim arising under federal law. Because Tamburo failed to adequately plead a federal antitrust claim, these jurisdictional options drop out of the case. We note for completeness that the circuits are divided over the proper interpretation of the venue and service-of-process language in § 22 of the Clayton Act.
See In re Auto. Refinishing Paint Antitrust Litig.,
. The parties and the district court have approached the jurisdictional question in this case by reference to the specialized framework proposed in
Zippo Manufacturing Co. v. Zippo Dot Com, Inc.,
At one end of the spectrum are situations where a defendant clearly does business over the Internet. If the defendant enters into contracts with residents of a foreign jurisdiction that involve the knowing and repeated transmission of computer files over the Internet, personal jurisdiction is proper. At the opposite end are situations where a defendant has simply posted information on an Internet Web site which is accessible to users in foreign jurisdictions. A passive Web site that does little more than make information available to those who are interested in it is not grounds for the exercise [of] personal jurisdiction. The middle ground is occupied by interactive Web sites where a user can exchange information with the host computer. In these cases, the exercise of jurisdiction is determined by examining the level of interactivity and commercial nature of the exchange of information that occurs on the Web site.
Some circuits have followed
Zippo
when "electronic contacts” over the Internet are at issue.
See, e.g., Revell v. Lidov,
. To the extent
Janmark
is understood to hold that jurisdiction is proper wherever the injury occurs, at least one of our sister circuits has questioned it.
See IMO Indus., Inc.,
. We note the circuits are also divided on the proper way to understand
Calder’s
emphasis on the defendant’s knowledge of where the “brunt of the injury” would be suffered.
Compare Dudnikov,
. In a case involving a stand-alone Internet-based defamation,
Calder
might require a showing that the defendant intended to reach forum-state readers.
See Young v. New Haven Advocate,
. The Supreme Court granted certiorari on this issue in
Carnival Cruise Lines, Inc. v. Shute,
. An additional approach, adopted by the Second Circuit, is a sliding-scale analysis that considers the connection between the contacts and the lawsuit.
See Chew v. Dietrich,
