Filing a Trade Secret Misappropriation Lawsuit

Filing a Trade Secret Misappropriation Lawsuit

May 26, 2026 by Lonnie Finkel

Trade secret litigation begins long before your company decides to file a complaint against the responsible parties. Once your company has reason to believe that confidential business information has been taken, copied or used improperly, the next question is not simply whether to sue. It is where to sue, whom to sue, what claims to bring, what evidence you have to prove those claims and secure immediate injunctive relief, and how to position the case so your company can stop further harm without creating unnecessary cost or risk. 

An early filing decision can materially shape the outcome of the case.  A well-planned trade secret lawsuit can improve your chances of obtaining injunctive relief, preserving confidentiality of the stolen information, and recovering damages. A poorly planned case can do the opposite by increasing expenses, complicating discovery, disclosing confidential information in a public forum, and weakening your ability to prove the information stolen is actually protected by law.

Your Initial Filing Decisions Can Impact the Entire Case

A trade secret case is not only about proving valuable information was taken. It is also about making smart strategic decisions from the outset, often under considerable time pressure, to stanch the flow of confidential information. If your company waits too long, the information may spread further, and once released it is difficult to recover.  If your company moves too quickly, without clearly identifying the stolen trade secrets, the complaint may be vulnerable to attack by the defendants and your lawsuit can become mired in costly and time-consuming procedural disputes that provide you little benefit.

That is why your litigation strategy should be tied to your business objective. In some matters, the immediate priority is a temporary restraining order or preliminary injunction to stop on-going dissemination and use of confidential information. In other cases, the better course of action may be a brief pre-filing effort to demand the return of the stolen information or, if you trust the defendants – which you reasonably may not – negotiate a standstill agreement while the parties discuss the facts surrounding the theft and subsequent dissemination of the confidential information, and engage in early settlement negotiations.

Timing is particularly important when your company is considering emergency relief. Courts expect a plaintiff requesting a temporary restraining order (TRO) and preliminary injunction (PI) to show urgency, identifiable harm, likelihood of success on the merits, and a factual record that connects the defendant’s conduct to the theft and misuse of the trade secrets. Delay undermines that showing.

At the same time, hastily filing a lawsuit without preparation can create its own problems. Before you file you should have a detailed working definition of the stolen trade secrets, a clear understanding and evidence of who had access to the information, and a evidentiary record showing how the information was taken, transferred or used, and by whom. The goal is not to know everything on day one.  That’s frequently unrealistic.  The goal is to have enough information to file a focused case that advances your company’s business objectives, and has the greatest chance of achieving your objectives, including securing a TRO and PI.

Should You File in Federal or State Court

One of the first major decisions is whether your company should file in federal or state court. In many cases both may be available, but they are not interchangeable.

When Federal Court Makes Sense Under the DTSA

The Defend Trade Secrets Act (DTSA) created a federal civil cause of action for trade secret misappropriation. If the trade secret is related to a product or service used in, or intended for use in, interstate or foreign commerce, federal jurisdiction may be available. For many modern businesses that threshold is not difficult to satisfy.

Federal courts can be attractive when your company wants a single forum for both federal and state trade secret claims, especially where the facts indicate the theft may spans multiple states. If your company is headquartered in California but the former employee now works in Maryland or Washington, D.C., federal court may be a wise choice to avoid state court bias and costly byzantine procedures. Federal court may also appeal when your company wants the benefit of the DTSA’s remedies and the streamline uniform procedures that come with federal practice. The DTSA includes procedural tools that protect confidentiality in litigation, which matters in any case where trade secret information is highly sensitive and particularly valuable.

When State Court May Be the Better Choice

State court may be a better venue if the dispute is deeply rooted in one state, the witnesses and evidence are largely local, and the core issues arise under that state’s trade secret statute and contract law.  For California companies seeking remedies under the California Uniform Trade Secrets Act (CUTSA) state court is often a logical forum when the facts, parties and resulting harm has occurred in state. California courts are familiar with the interplay between trade secret claims, common law tort claims, employee mobility issues, and California’s strong public policy against non-compete agreements.

For our East Coast clients, similar forum questions arise.  If your company is based in Maryland or Washington D.C., or if the relevant conduct occurred there, state or federal filing options will deserve careful comparison. The right forum for your company’s trade secret case depends on the specific facts of the case, not on a one-size-fits-all rule.

A Strong Complaint May Include Both Federal and State Law Claims

In practice, many trade secret lawsuits plead both DTSA and CUTSA claims when federal jurisdiction is available. For a California company, that often means pairing a DTSA claim with a CUTSA claim. That approach can preserve flexibility, broaden available legal theories of recovery, and allow the court to address the dispute in one place.

How Courts Determine Which State’s Law Applies

In multi-state disputes, the next question is often which state’s law will govern. That issue can matter significantly because trade secret law, contract law, and employment-related defenses do not operate identically across jurisdictions.

There is no single universal rule. Courts usually begin with the forum state’s choice-of-law principles and then examine which state has the most significant relationship to the dispute. In a trade secret case, that analysis may include where the employment relationship was based, where agreements were signed, where the alleged misconduct occurred, where the trade secrets were stored and accessed, where the competitive use occurred, and where the injury was felt.

For California companies this issue can become especially important when agreements include foreign law or venue clauses, or when a departing employee moves to a competitor outside California. California’s public policy regarding employee mobility can affect how courts evaluate contractual provisions and related claims.

California’s Reasonable Particularity Requirement Affects Strategy Early

California has an important procedural rule that may influence your filing strategy from the start. Before a plaintiff can begin discovery of a trade secret claim under CUTSA, the plaintiff must identify the alleged trade secret with reasonable particularity. The requirement does not mean your company must reveal every detail of the trade secret in the complaint, but it does mean vague categories like “confidential business information” or “customer data” will not pass muster with the court.

This is one reason your company should avoid overreaching. A well written complaint identifies the trade secrets narrowly, clearly and consistent with the actual evidence. This discipline strengthens the pleading, clarifies for the court the information stolen, and allows discovery to commence sooner and proceed more expeditiously.

Where Your Company Should File the Lawsuit

When deciding where to file your company’s trade secret lawsuit focus on where the unlawful conduct and harm actually occurred.  Courts will examine where the alleged unlawful acquisition, use or disclosure took place. That means your company should consider more than its headquarters address. Relevant facts include where the former employee worked, where your company’s information management systems was accessed, where files were downloaded, where a new employer is using the information, and where the resulting damages are occurring. The physical location of a server is only one factor. If your company’s information is stored in the cloud, the more persuasive facts may be where people actually interacted with the information and where the misuse affected your company’s operations, customers and market opportunities.

Who Are the Defendants

Many companies understandably focus first on the departing employee. In some cases, that is enough. In others, limiting the case to the former employee may leave your company without its most important legal remedies or without access to the evidence needed to prove what happened.  The new employer may be an appropriate defendant when the evidence suggests it encouraged, received, benefited from or turned a blind eye to its new employee’s use of your company’s trade secrets. This can arise where the new employer hired the employee in a role that predictably depended on his use of your company’s trade secrets or failed to quarantine the information after learning of the issue.

Naming the new employer is especially important if your company’s real concern is not just possession, but on-going use and further dissemination. An injunction against only the former employee may not fully address the practical risk if the new employer already has access to the information, or if the evidence is primarily in the new employer’s systems, messages, and decision-making records.

Including the new employer may also improve your company’s ability to recover damages and reach a settlement. A new employer often has deeper resources, a stronger incentive to resolve the matter quickly, and control over the workplace environment where the disputed information may now reside.

That said, naming a new employer should never be automatic. It should be tied to the evidence and your company’s litigation objectives, not used as a pressure tactic. Overreach can make the case more expensive and invite unnecessary counterclaims.

When Third Parties Should Be Named

Misappropriation does not always stop with the employee and a new employer. In some matters, third parties may have assisted the transfer, received the information, or used it in a way that makes them proper defendants.

This can include consultants, vendors, business partners, startup co-founders, or other entities that knowingly received or exploited the information. It can also include parties who were involved in setting up the systems, accounts, or channels through which the trade secret was transmitted or deployed.

The key question is whether naming certain third parties will materially improve your company’s ability to stop the misuse, recover the information, develop the evidence and prove your damages. If the answer is yes, including those parties may make sense.

How Additional Defendants Can Support Recovery and Discovery

A well-chosen defendant group can improve the effectiveness of a trade secret misappropriation lawsuit because the right parties often control the right evidence.

When your company names all relevant actors, discovery can proceed more directly.  Instead of fighting through third-party subpoenas and incomplete document production, your company may be able to obtain system records, communications, device data, and decision-making evidence straight from the parties most involved. That can reduce delay and make it harder for each actor to blame someone else.

Additional defendants may also improve the practical value of any relief obtained. A court order directing return, non-use, deletion or quarantine of confidential information is more effective when it binds the parties who actually possess or control the trade secrets. Still, more defendants also mean more motion practice, more attorneys, and higher costs.  The decision should be strategic, not reflexive.

Confidentiality, Cost, and Practical Litigation Strategy

Trade secret lawsuits present a recurring tension. Your company wants to protect confidential information, but litigation requires enough disclosure to tell the court what happened and why relief is justified.

That tension should be addressed in the pleading strategy from the start. The complaint should define the trade secrets carefully without making unnecessary public disclosures. Protective orders, sealed filings where appropriate, and a disciplined approach to exhibits all matter. This is true in California, and it is just as important in disputes involving Maryland or Washington D.C. defendants or operations.

Your company should also evaluate whether the expected benefit of litigation justifies the cost. A fast, targeted lawsuit can be the right tool when misuse is ongoing and the threatened harm is imminent and serious. In other cases, a negotiated return-and-verification process, a narrowly tailored cease-and-desist effort, or a short standstill agreement may accomplish the business objective more efficiently.
