What to do if you are sued in a US federal court for IP infringement in another state?

If you are sued in a US federal court for IP infringement in another state, you generally have exactly 21 days to file a response. To protect your business, you can often file a Motion to Dismiss for lack of personal jurisdiction, or request a Change of Venue (Motion to Transfer) to move the federal case back to your home state, saving you immense travel costs.

Opening your mail to find a federal summons indicating you are being sued halfway across the country is one of the most stressful moments for any American business owner. 😱 In the USA, “forum shopping” is a very common tactic where a plaintiff files an intellectual property lawsuit in a specific state—like the Eastern District of Texas for patents, or the Central District of California for copyrights—hoping to gain a strategic advantage. As the out-of-state defendant, you are suddenly faced with the terrifying prospect of paying massive travel fees, hiring local lawyers, and defending yourself in unfamiliar territory. Fortunately, federal law provides strict rules to prevent you from being unfairly dragged across the nation.

Being sued in a federal District Court is vastly more complicated than handling a local moving violation at your state DMV or responding to a standard tax notice from the IRS. 💼 It also has absolutely zero connection to state-level personal family disputes like finalizing child custody or calculating alimony/spousal support. Furthermore, unlike a simple workplace dispute mediated by the EEOC, ignoring a federal IP lawsuit will result in a disastrous default judgment, locking in massive financial liability against you. Because there are strict deadlines similar to a rigorous statute of limitations, you must act quickly to challenge the location of the trial or force an early settlement in your favor.

Step-by-Step Process in the USA

Defending against an out-of-state federal lawsuit is a high-stakes procedural battle. 📈 Because IP litigation (like patents, trademarks, and copyrights) relies on federal statutes, the overarching rules are the same nationwide, but proving your connection to a specific state is critical. Most defendants generally follow these precise steps to challenge the lawsuit’s location and protect their home turf.

Step 1: Never Ignore the Summons

The worst possible thing you can do when sued in another state is to throw the paperwork in the trash. 🚨 Under the Federal Rules of Civil Procedure, you generally have exactly 21 days from the date you were officially served to file an answer or a pre-answer motion. If you fail to respond by this strict deadline, the out-of-state judge will enter a default judgment, granting the plaintiff exactly whatever monetary damages they asked for without you ever having a chance to defend yourself.

Step 2: Evaluate Personal Jurisdiction

Before you argue about whether you actually infringed the patent or copyright, your attorney will evaluate if the court even has power over you. 🔍 This is called “personal jurisdiction.” To be sued in a state like Florida, you generally must have “minimum contacts” there—such as a physical office, targeted advertising to Florida residents, or a history of selling the infringing products directly into that state. If your small bakery is located strictly in Oregon and you never sold anything to Florida, the Florida court likely has no legal authority over you.

Step 3: Filing a Motion to Dismiss or Transfer

If you lack ties to the plaintiff’s chosen state, your attorney will typically file a Motion to Dismiss for Lack of Personal Jurisdiction under Rule 12(b)(2). 📝 Alternatively, even if the court *does* have jurisdiction, your lawyer might file a Motion to Transfer Venue under 28 U.S.C. § 1404(a). This motion asks the judge to move the case back to your home state for the convenience of the witnesses, the location of your evidence, and in the interest of overall justice.

Step 4: Hiring Local Counsel (If Necessary)

While you fight to move the case, federal court rules generally require you to be represented by an attorney admitted to practice in that specific out-of-state district. 💻 This means your primary hometown attorney must partner with a “local counsel” in the opposing state to file the paperwork on your behalf. Navigating these complex dual-attorney dynamics is exactly why transferring the case back to your home state is the ultimate priority.

How Much Does it Cost in the USA?

Fighting a venue battle in a US federal court requires a significant upfront financial commitment. 💰 While the courts generally do not charge massive fees just to submit motions, the specialized legal analysis required to draft these jurisdictional arguments is expensive. Here is a breakdown of what it might cost to fight being sued in another state.

Expense TypeEstimated Cost (USD)Description
Motion Filing Fees$0Generally, there is no federal court fee for a defendant to file a Motion to Dismiss or Transfer.
Local Counsel Fees$2,000 – $5,000+The cost to retain a lawyer physically located in the out-of-state district just to sponsor your home attorney.
Jurisdictional Defense$10,000 – $30,000+The legal fees paid to your primary IP attorney to research case law and draft the complex transfer motion.
Settlement CostsVaries widelySometimes, the high cost of fighting an out-of-state battle forces defendants to negotiate an early payout.

How Long Does the Process Take?

The fight over jurisdiction happens at the very beginning of the lawsuit. ⏱️ As noted, you must act within the initial 21-day window to file your motion. Once your Motion to Transfer or Motion to Dismiss is filed, the opposing party gets time to write a response, and you get time to reply.

It typically takes the federal judge anywhere from 1 to 4 months to read the briefs, hold a hearing, and issue a final decision on whether the case will stay or be relocated to your home state. 📅 During this waiting period, the judge will often temporarily pause (stay) the incredibly expensive process of legal discovery, saving your business thousands of dollars until the proper location is firmly established.

Frequently Asked Questions (FAQ)

What if I have an online store that sells globally?

In the digital age, jurisdiction is tricky. Generally, operating a passive website that anyone can view is not enough to be sued everywhere. However, if your website is highly interactive and you regularly ship infringing products directly to customers in the plaintiff’s state, that state likely has personal jurisdiction over you.

What is the patent specific venue statute?

For US patent infringement (unlike copyright or trademark), there is a very strict rule under 28 U.S.C. § 1400(b). Following the Supreme Court’s TC Heartland decision, a corporation can generally only be sued for patent infringement in its state of incorporation, or where it has committed acts of infringement and has a regular, established place of business.

Can I just represent myself to save money?

If your business is a registered LLC or corporation, no. US federal court rules mandate that corporate entities must be represented by a licensed attorney. Only individuals acting purely on their own personal behalf can represent themselves (pro se), which is highly discouraged in complex IP cases anyway.

What happens if the judge grants my Motion to Transfer?

If the judge agrees with you, the entire lawsuit is digitally boxed up and physically transferred to the Federal District Court in your home state. You will not have to pay the plaintiff’s initial filing fees again, and the trial will proceed locally.

What if I miss the 21-day deadline?

If you fail to respond within 21 days, the plaintiff can request an Entry of Default. If granted, you essentially lose the case automatically. Overturning a default judgment is incredibly difficult and requires proving you had an excusable, highly unusual reason for missing the deadline.

Does transferring the case mean I won?

No. Winning a transfer motion simply moves the battlefield to your home turf. You still must defend your business against the actual allegations of copyright, trademark, or patent infringement in your local federal court.
