Plaintiff Mobile Anesthesiologists Chicago is a company based in Chicago that contracts with medical offices to provide on-site anesthesia services. Defendant Anesthesia Associates of Houston Metroplex is a much smaller operation consisting of one doctor providing similar services in Houston, Texas. We refer to the parties as Mobile/Chieago and Mobile/Houston. Mobile/Chicago brought suit against Mobile/Houston in federal court in Illinois claiming that Mobile/Houston violated the federal anti-cybersquatting statute by registering a domain name confusingly similar to Mobile/Chicago’s registered trademark. The district court dismissed the suit for lack of personal jurisdiction.
We affirm. First, we conclude that Mobile/Houston did not waive its personal jurisdiction defense by asking to delay a preliminary injunction hearing or by ask *442 ing for expedited discovery to prepare for that hearing. Second, we agree with the district court that Mobile/Houston lacked the required “minimum contacts” with Illinois to support personal jurisdiction there. Mobile/Chicago relies principally on the inference that Mobile/Houston expressly aimed its conduct in Texas at harming Mobile/Chicago in Illinois. That inference is based on two inadequate connections between Mobile/Houston and Illinois: (1) Mobile/Houston’s creation of a website accessible in Illinois but aimed only at the Houston market, combined with Mobile/Houston’s constructive notice of Mobile/Chicago’s trademark via federal registration of that mark; and (2) Mobile/Houston’s receipt of Mobile/Chicago’s cease-and-desist letter. These contacts are not sufficient to establish that Mobile/Houston’s activities in Texas were calculated to cause harm in Illinois.
I. Factual and Procedural Background
Mobile/Chicago has been operating in the Chicago area since 1996. The company has affiliated offices in other cities, including Houston. The record does not reveal exactly when Mobile/Chicago’s Houston affiliate began operations, but Mobile/Chicago alleges that it advertised its services in Houston in 2008.
In 2003, Mobile/Chicago registered the website <www.mobileanesthesiologists. com>, which it continues to operate today. Mobile/Chicago also owns a federally registered trademark in the words MOBILE ANESTHESIOLOGISTS. It obtained the trademark registration in 2005.
Mobile/Houston was established by Dr. Eric Chan, its sole member, in 2007. On August 22, 2008, Dr. Chan registered the website <www.mobileanesthesia.com>.
Working under Mobile/Houston’s name, Dr. Chan operates as an independent contractor providing anesthesia services for patients in clinics and medical offices throughout the Houston area.
Dr. Chan’s professional activities are limited entirely to the state of Texas. He is licensed as an anesthesiologist by the State of Texas but has not been licensed in any other state. He has never advertised his services other than on his website (which offers anesthesia services “in the greater Houston area” and provides a Houston-area phone number) and in a printed advertisement published in Texas.
Dr. Chan has visited Illinois just once, on vacation in 2003. He has never visited Illinois for business, has never conducted business in Illinois, and has no agent or offices in Illinois. He has never attended events or performed duties in Illinois for any of the professional associations to which he belongs. And although he surely knew there were anesthesiologists in Illinois too, Dr. Chan was unaware that Mobile/Chicago, its trademark, or its website existed until he received a cease-and-desist letter from its lawyer in December 2008. There is no evidence that anyone else associated with Mobile/Houston has any relevant contacts with Illinois.
The district court dismissed Mobile/Chicago’s suit for lack of personal jurisdiction. The court pointed out that Mobile/Houston lacks any meaningful contacts with Illinois and that its website, though bearing a name similar to Mobile/Chicago’s, is not directed at Illinois in any way. The assertion that Dr. Chan, sitting in Houston, knew about Mobile/Chicago and intended to do it harm in Illinois, was “entirely unsupported” and an “empty conclusion.”
II. Waiver
Mobile/Chicago begins with the bold argument that Mobile/Houston waived its right to argue lack of personal jurisdiction when it asked for a continu *443 anee of the preliminary injunction hearing and an expedited discovery schedule. We disagree.
Mobile/Chicago filed its lawsuit in the Northern District of Illinois on February 13, 2009 and requested a preliminary injunction to stop Mobile/Houston’s use of its domain name. The court scheduled a hearing for March 6, 2009. On March 3rd, Mobile/Houston’s counsel filed a motion to continue the preliminary injunction hearing, which Dr. Chan could not attend because he was scheduled to see patients in Texas that day. The motion also requested expedited discovery to prepare for the hearing. Thirteen days later, on March 16, 2009, Mobile/Houston filed its Rule 12(b)(2) motion to dismiss for lack of personal jurisdiction.
These preliminary actions do not come close to what is required for waiver or forfeiture. To waive or forfeit a personal jurisdiction defense, a defendant must give a plaintiff a reasonable expectation that it will defend the suit on the merits or must cause the court to go to some effort that would be wasted if personal jurisdiction is later found lacking. See,
e.g., American Patriot Ins. Agency, Inc. v. Mutual Risk Management, Ltd.,
III. Specific Jurisdiction
In a federal question case such as this one, a federal court has personal jurisdiction over the defendant if either federal law or the law of the state in which the court sits authorizes service of process to that defendant.
Omni Capital International, Ltd. v. Rudolf Wolff & Co., Ltd.,
Under the Supreme Court’s well-established interpretation of the Fourteenth Amendment’s due process clause, a defendant is subject to personal jurisdiction in a particular state only if the defendant had “certain minimum contacts with it such that the maintenance of the suit does not offend ‘traditional notions of fair play and substantial justice.’ ”
International Shoe Co. v. Washington,
Personal jurisdiction can be general or specific, depending on the extent of the defendant’s contacts. See
Tamburo,
Mobile/Houston did not purposefully direct its activities at Illinois. It has formed no contracts in Illinois and has had no physical presence there. Mobile/Chicago points to the fact that Dr. Chan is a member of two professional associations headquartered in Illinois, but those are the kinds of fortuitous contacts that the Supreme Court has repeatedly held do not support personal jurisdiction where the contacts bear no relationship to the lawsuit. See,
e.g., Burger King,
But Mobile/Chicago contends that Mobile/Houston has done two things in Texas to subject itself to suit in Illinois. First, Mobile/Houston has maintained a website with a name similar to Mobile/Chicago’s trademark, with constructive notice of that trademark thanks to Mobile/Chieago’s federal registration. Second, after receiving the cease-and-desist letter, Mobile/Houston has maintained its website with actual notice of Mobile/Chicago’s identity, location, and ownership of a similar mark. From these facts, Mobile/Chicago argues, we should infer that Mobile/Houston intended to injure Mobile/Chicago in Illinois, and from that intent we should find the contacts needed to satisfy due process. This argument is not persuasive.
The Supreme Court has held that constitutionally sufficient contacts can be imputed to a defendant if the defendant is accused of committing an intentional tort by actions that are “expressly aimed” at the forum state. See
Calder v. Jones,
As we recognized in
Tamburo,
Our decision in
Indianapolis Colts, Inc. v. Metropolitan Baltimore Football Club Ltd. P’ship,
Janmark, Inc. v. Reidy,
We view
Wallace
as a correct statement of the standard set down by the Supreme Court. As in
Tamburo,
we do not read
Indianapolis Colts
or
Janmark
to conflict with
Calder,
which made clear that a defendant’s intentional tort creates the requisite minimum contacts with a state only when the defendant expressly aims its actions at the state with the knowledge that they would cause harm to the plaintiff there.
Tamburo,
Mobile/Chicago’s evidence that Mobile/Houston took express aim at Illinois is inadequate. Mobile/Chicago first contends that we should infer express aiming at Illinois from the fact that Mobile/Houston operates a website whose domain name is similar to Mobile/Chicago’s trademark. We disagree. A plaintiff cannot satisfy the
Calder
standard simply by showing that the defendant maintained a website accessible to residents of the forum state and alleging that the defendant caused harm through that website. See,
e.g., Panavision International, L.P. v. Toeppen,
Still less does Mobile/Houston’s website create constitutionally sufficient contacts with Illinois in the absence of express aiming. A defendant’s deliberate and continuous exploitation of the market in a forum state, accomplished through its website as well as through other contacts with the state, can be sufficient to establish specific personal jurisdiction. See,
e.g., uBID, Inc. v. The GoDaddy Group, Inc.,
Trying a second path to show “express aiming,” Mobile/Chicago argues that its federal trademark registration gave Mobile/Houston “constructive notice” that it was infringing Mobile/Chicago’s trademark and could be called to court in Illinois. This argument misunderstands the purpose of federal registration. The federal trademark statute on which Mobile/Chicago sued does not authorize nationwide service of process. See,
e.g., Sunward Electronics, Inc. v. McDonald,
Finally, Mobile/Chicago points out that Mobile/Houston also had actual notice of Mobile/Chicago’s trademark from the moment it received Mobile/Chicago’s cease- and-desist letter. From that time forward, Mobile/Chicago argues, Mobile/Houston was intentionally directing its tortious activities at Illinois in the same way that the defendants in
Calder
intentionally directed their tortious activities at California. This argument finds no sup
*447
port in the case law. The cases that have found express aiming have all relied on evidence beyond the plaintiffs mere residence in the forum state. See,
e.g., Colder,
Affirmed.
Notes
. In the past, the reasoning in
Calder
has been called the "effects test.” We believe the phrase "express aiming test” — adopted by this court in
Tamburo,
