Global Perspectives on Trade Secrets Protection

Trade secrets are among the most commercially significant but legally underappreciated forms of intellectual property. The formula for Coca-Cola, KFC’s blend of herbs and spices, Google’s search algorithm – none of these are patented. They are protected as trade secrets. Unlike patents, trademarks, or copyrights, trade secrets require no registration, carry no expiry date, and can protect virtually any kind of confidential business information. But that also means their protection depends entirely on the legal framework each country has in place – and those frameworks differ widely. Understanding how different jurisdictions protect trade secrets is essential for any business or legal professional operating in today’s knowledge-driven economy.

What qualifies as a trade secret? 🔗

Before comparing national laws, it helps to understand what information qualifies as a trade secret across jurisdictions. According to WIPO, most legal systems converge on three core requirements: the information must not be generally known or readily accessible to those in the relevant industry; it must have commercial value because it is secret; and the owner must have taken reasonable steps to keep it secret. These requirements mirror the three-pronged test set out in Article 39.2 of the TRIPS Agreement, which forms the international baseline for trade secret protection among WTO member countries.

The category of information that can qualify is broad. Courts across jurisdictions have recognised pricing structures, manufacturing processes, software source code, customer lists, drug formulation data, supply chain models, and business strategies as protectable trade secrets. Trade secret regimes often fill the gaps left by other IP rights – customer lists are unlikely to be protected by copyright, and manufacturing processes may be difficult to enforce under patent law, particularly when competitors cannot determine the process from the finished product. Maintaining secrecy can also offer longer-lasting protection than a 20-year patent monopoly.

The international baseline: TRIPS Agreement 🔗

The most important international instrument governing trade secret protection is the TRIPS Agreement of 1995, specifically Article 39, which for the first time brought trade secrets – referred to as “undisclosed information” – under the formal umbrella of international intellectual property law. Before TRIPS, trade secrets were protected in various countries through contract law, tort, or equity principles, but there was no consistent global standard.

Article 39 requires WTO member states to protect undisclosed information from disclosure, acquisition, or use by others without consent, where such conduct is contrary to honest commercial practices. The footnote to Article 39 explicitly includes breach of contract, breach of confidence, inducement to breach, and acquisition by a third party who knew or was negligent in not knowing that the information was obtained improperly. Importantly, TRIPS does not mandate any particular legal mechanism – countries can use contract law, tort, unfair competition law, or dedicated statutes, as long as effective protection is available. This general formula has been adopted by well over 100 of the WTO’s member states.

One critical point: Article 39 does not grant trade secret holders absolute rights in the way patent law does. Protection is triggered only when there is an element of dishonesty or unfairness. This means that reverse engineering, independent discovery, or parallel innovation is generally lawful – a competitor who arrives at the same information through legitimate means faces no liability.

The United States: trade secrets as property rights 🔗

The United States has the most developed and extensively codified trade secret law in the world. The legal framework rests on two pillars: the Uniform Trade Secrets Act (UTSA), which has been adopted in some form by nearly all U.S. states, and the federal Defend Trade Secrets Act (DTSA) of 2016, which created a federal civil cause of action for misappropriation.

The DTSA is particularly significant because it expressly treats trade secrets as a form of property right. It also has limited extraterritorial reach – it applies to conduct outside the U.S. where the act in furtherance of the offense was committed in the United States, or the offender is a U.S. person. There is a presumption that U.S. law applies only within U.S. borders, but the DTSA is an exception to this general rule. Under exceptional circumstances, the DTSA also permits courts to issue ex parte seizure orders – allowing law enforcement to seize property to prevent the spread of a misappropriated trade secret before the defendant is even notified of the proceedings.

Remedies under U.S. law are robust: they include injunctive relief, compensatory damages, and in cases of wilful misappropriation, exemplary damages of up to twice the compensatory award and attorney’s fees. This combination of civil and quasi-criminal remedies makes the U.S. system one of the most potent in the world for trade secret enforcement.

The European Union: from fragmentation to harmonisation 🔗

Before 2016, trade secret protection across EU member states was deeply inconsistent. In France, protection was limited to manufacturing secrets; in Germany and the Netherlands, trade secrets were protected under general unfair competition principles. A company operating across Europe had to navigate radically different rules in each member state.

This changed with EU Directive 2016/943 on the Protection of Trade Secrets, which harmonised the definition of trade secrets and the civil remedies available across EU member states. The Directive defines trade secrets in terms closely aligned with TRIPS: the information must be secret, have commercial value because of its secrecy, and the holder must have taken reasonable steps to maintain secrecy. The Directive treats trade secrets less as absolute property rights and more as business assets deserving protection where the owner has invested effort in keeping them confidential.

The remedies under the Directive are comprehensive. Member states are required to make available provisional measures (including preliminary injunctions to prevent further disclosure), permanent injunctions, corrective measures such as product recall or destruction, and damages. When calculating damages, courts must account for negative economic consequences, lost profits, unfair gains by the infringer, and in appropriate cases, the moral harm caused to the trade secret holder. Where applying an injunction would be disproportionate – such as when only a small part of a product contains the protected information – courts may instead order pecuniary compensation as an alternative.

The Directive also carves out important exceptions. Acquiring or disclosing a trade secret is not unlawful when done to exercise freedom of expression, expose wrongdoing in the public interest, or fulfil workers’ rights to information and consultation. Reverse engineering of publicly available products remains explicitly lawful.

The United Kingdom: parallel regimes 🔗

The UK operates with two overlapping systems for trade secret protection. The first is the equitable doctrine of breach of confidence, which traces its origins to the 1849 case of Albert v. Strange and protects a wide range of confidential information beyond just trade secrets. The second is the Trade Secrets (Enforcement, etc.) Regulations 2018, which implemented the EU Trade Secrets Directive in the UK before Brexit. The two regimes coexist, and where broader protection is available under the common law, rights holders can rely on it in addition to the statutory regulations.

The common law approach focuses on the relationship of confidence – courts intervene where information was shared in circumstances that imposed an obligation of confidentiality. The statutory framework, by contrast, focuses on the commercial value of the secret and the steps taken to protect it. Where both apply, the broader protection governs. Remedies include damages, an account of profits, and injunctive relief, with courts typically granting final injunctions to successful litigants.

Civil law jurisdictions: torts, unfair competition, and unjust enrichment 🔗

Many civil law countries – particularly in continental Europe, Latin America, and parts of Asia – do not treat trade secrets as a distinct property right. Instead, protection flows from broader legal doctrines such as unfair competition, tort law, or unjust enrichment. In these systems, the focus is not on the nature of the information as “property,” but on the conduct of the party who misappropriated it. Was the acquisition dishonest? Did it violate fair commercial practices? Was the defendant unjustly enriched at the expense of the plaintiff?

The practical effect is that the same underlying wrong – stealing a competitor’s confidential business information – may be characterised differently depending on the jurisdiction. In Germany, for example, protection was historically grounded in unfair competition law, and criminal sanctions for trade secret theft have long been part of the framework. In Japan, the Unfair Competition Prevention Act provides explicit statutory protection for trade secrets and includes both civil and criminal remedies. Trade secret law is territorial, just like patent and trademark law, which means that misappropriation occurring in one country may need to be enforced separately in each jurisdiction where the secret is used.

Remedies across jurisdictions: where the differences are most stark 🔗

The remedies available for trade secret misappropriation are broadly similar in concept across major jurisdictions – injunctions to stop further disclosure or use, and damages to compensate the harm caused. However, the scope and effectiveness of these remedies vary significantly in practice.

In the U.S., the availability of exemplary damages and attorney’s fees in cases of wilful misappropriation creates a strong deterrent. In the EU, the Trade Secrets Directive harmonised civil remedies but left criminal enforcement to member states, meaning that criminal consequences for trade secret theft vary considerably across Europe. In common law countries like Australia, courts readily grant final injunctions as a matter of course, whereas in some civil law systems, injunctive relief may be harder to obtain or subject to additional procedural requirements.

A particularly challenging area is calculating damages. National rules on damages calculation do not always account for the intangible nature of trade secrets, making it difficult to demonstrate actual profits lost or the infringer’s unjust enrichment where no market value exists for the information. The EU Directive addressed this partially by allowing courts to calculate damages as a lump sum based on a hypothetical reasonable royalty – the amount that would have been due had the infringer obtained a licence. This approach is increasingly being adopted in other jurisdictions as well.

Why trade secrets matter across industries 🔗

Trade secrets are not just the concern of large technology companies. They are critical across sectors: pharmaceutical companies protect clinical trial data and drug formulations; manufacturers protect production processes; financial services firms protect algorithmic trading strategies; and even small businesses rely on customer lists, pricing data, and supplier relationships as confidential competitive advantages. For small and medium enterprises in particular, trade secrecy is often the primary method of protecting business advantage – easier and cheaper than the registration-based IP systems that protect patents or trademarks.

The increasing digitisation of business has made trade secret protection more urgent. High-profile cases – like Pfizer suing an employee who uploaded thousands of confidential files to a personal Google Drive, or Apple suing a former employee for selling trade secrets to media – illustrate that even sophisticated companies with robust internal policies are vulnerable. The legal framework a company operates in can determine whether it has meaningful recourse when those policies fail.

Challenges in cross-border enforcement 🔗

One of the most significant practical challenges in global trade secret protection is cross-border enforcement. Unlike with other IP rights where the territorial limitation is well understood, trade secrets can spring to life simultaneously in multiple jurisdictions because they consist of information untethered to any geographic location. A secret that is misappropriated in one country and exploited in another may require parallel litigation in multiple jurisdictions, each with its own procedural rules, evidentiary standards, and remedies.

Establishing jurisdiction over foreign defendants, enforcing judgments across borders, and maintaining confidentiality of the very secret at issue during public court proceedings are challenges that no single international treaty has fully resolved. The TRIPS Agreement sets minimum standards but leaves significant discretion to member states on enforcement mechanisms. Until more comprehensive international harmonisation emerges, businesses must take a proactive, multi-layered approach – combining non-disclosure agreements, access controls, employee education, and jurisdiction-specific legal strategies – to protect their most valuable confidential information globally.

What do you think? Given that trade secrets can be protected indefinitely – unlike patents which expire after 20 years – should there be stronger international standards that regulate how long trade secret protection can last? And with the rise of digital workplaces and remote work making information easier to exfiltrate, do existing legal frameworks across jurisdictions do enough to deter misappropriation before it occurs?
