What does Trade Secret mean?
In legal practice, a trade secret is commercially valuable confidential information that a business keeps secret and protects against unauthorised acquisition, use or disclosure. In the UK, the concept is defined in the Trade Secrets (Enforcement, etc.) Regulations 2018; in Ireland it is defined in the European Union (Protection of Trade Secrets) Regulations 2018, both implementing Directive (EU) 2016/943. Information is a trade secret if it is: (i) secret in the sense of not generally known or readily accessible to people within the circles that normally deal with that kind of information; (ii) has commercial value because it is secret; and (iii) is subject to reasonable steps to keep it secret by the person lawfully in control. Typical examples include formulas, source code, algorithms, manufacturing processes, customer lists, pricing strategies and business plans. In disputes, claims focus on unlawful acquisition, use or disclosure (misappropriation), with remedies including interim and final injunctions, delivery up or destruction, damages or an account of profits, and confidentiality measures in proceedings. The statutory regime sits alongside the common law/equitable action for breach of confidence (including employee misuse of confidential information). Usage and core criteria are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland.

UK extradition instructions checklist post-EAW under the EU–UK Trade and Cooperation Agreement

Set out below are the key practical competition law considerations when preparing and submitting the Form CO to the European Commission (the Commission): Confirm eligibility for a Short Form CO to reduce disclosures. Build in time; a full Form demands extensive data, including Member State market shares. For turnover, use the Commission’s official ECB exchange rate and support the filing with economic analysis. If information is unavailable, explain why and estimate; if requests seem irrelevant, justify and obtain a waiver with the case team. Check accuracy; inaccuracies render the Form CO ineffective until the Commission is satisfied. Provide precise contact details for customers, competitors and suppliers, and include caveats for any assumptions. Allow time for authorisations and, where required, signature of the declaration by the relevant business person or in-house lawyers. Prepare required copies (one original, three paper, two CD or DVD) and translate supporting documents not in an EU official language. Review supporting documents for any “anti-competitive” language...

US Eleventh Circuit: AAI's Missouri Trade Secrets Act claim against Boeing revived; unjust enrichment permitted notwithstanding contractual limitation; reassignment bid rejected

In a 31-page published opinion, the Eleventh Circuit overturned the lower court’s dismissal of Alabama Aircraft Industries Inc, formerly Pemco, under the Missouri Trade Secrets Act, but clarified that unjust enrichment is the sole remedy it can obtain against Boeing, as the parties’ contracts blocked all other avenues of relief AAI might pursue. The decision is the latest turn in a years-long trade secret misappropriation and breach of contract dispute first brought in 2011. AAI claimed Boeing pursued a prolonged strategy to capture a lucrative US Air Force contract for servicing the KC-135 aerial refuelling aircraft, a contract AAI said it had held for decades. The companies initially agreed in the 2000s to team up on a maintenance bid. However, AAI alleged Boeing later excluded it from the arrangement and then secured the award by pricing just 1% below AAI’s proposal. When the matter finally went to trial in 2020, a jury awarded AAI more than US$2 m for Boeing’s alleged conduct, which included breaching a non-disclosure agreement and their...

NDAs, public domain carve-outs and trade secrets: Illiquidx v Altana [2025] EWHC 299 (Ch)—misuse established; confidentiality preserved despite limited disclosures; copyright infringement not proved (England and Wales)

Illiquidx Ltd v Altana Wealth Ltd and others [2025] EWHC 299 (Ch) What are the practical implications of this case? This decision highlights the need for precise, clear definitions and clauses in NDAs, especially concerning the boundaries of confidential information and what falls within the public domain. Equally, spelling out permitted disclosures reduces uncertainty; providing information to third parties does not, on its own, render it public or remove its confidentiality. The court will evaluate disclosures on their individual facts, with the key consideration being how far the veil of secrecy still remains. It is also prudent to set out contractually how confidential information will be handled if a commercial relationship ends or breaks down unexpectedly. Measures might include requiring confidential information (and any materials that contain it) to be returned, deleted, or destroyed. For trade secret protection, the absence of an NDA does not automatically mean the obligation to take reasonable steps to keep material secret is unmet. The court will assess the context and...

UK and EU IP update: Court of Appeal curbs service-out for trade secret claims; limits on iniquity exception after entrapment; EUIPO influencer IP study; webinars and trackers

Playtech contended that, after leaving its Latvian affiliate, Veliks accessed confidential pre‑launch game material via the Horizon platform, which Realtime then exploited to create competing games. The court concluded that all the impugned conduct occurred in Latvia and any UK loss was merely a consequential economic effect. Consequently, Gateway 21 was not satisfied, as it requires direct damage within the jurisdiction or an obligation of...

US IP comparison for literary works, marketing images, characters, slogans, product designs and inventions: copyright, trade secrets, trade marks, trade dress, design patents and utility patents [Archived]

ARCHIVED: This Practice Note is archived and no longer updated. It was initially prepared for Lexis Practice Adviser, in the US. It outlines similarities and differences between the protections available for typical categories of IP, such as literary works (copyright and trade secret); marketing imagery, characters and slogans (copyright and trade mark); product designs (design patent, copyright and trade dress) and inventions (patent and trade secret). It addresses coverage and duration, as well as scope and eligibility requirements too. Literary works—copyright versus trade secret protection For information to amount to a trade secret, it must truly be confidential, the proprietor must take steps to preserve that confidentiality, and it must confer a competitive economic benefit on the owner. Trade secrets usually comprise commercial or business information and may endure without limit, provided the secrecy is maintained. Copyright, by contrast, applies to subject matter such as literary works, audiovisual works, and sound recordings, and only requires that the work is fixed in a tangible medium of expression. Copyright protection...

Semiconductor topography rights in the UK: subsistence, qualification (including WTO countries), ownership, duration, infringement and reverse engineering; exhaustion and parallel imports; and complementary copyright, patent and trade secret protection

Background to semiconductors A semiconductor is, at its core, a material with electrical conductivity that can permit or, alternatively, obstruct the passage of electric current. Chips based on semiconductors—seen in devices such as computers, mobile phones and microwave ovens—are typically produced from circular silicon wafers. Intellectual property rights operate to safeguard the semiconductor sector, encompassing electronic circuit boards and the component chips. Semiconductor topography rights The semiconductor topography right sits alongside unregistered design law and is aimed at protecting a particular industrial article, namely, as noted above, the electronic circuit board and the layout of semiconductors. This right entered UK law through the Design Right (Semiconductor Topographies) Regulations 1989, SI 1989/1100, which implemented European Directive 87/54/EC and now form assimilated law as EU‑derived domestic legislation. Assimilated law is the term applied to retained EU law (REUL) that continues in force after the end of 2023. The shift from REUL (and related expressions) to assimilated law denotes a change in its status and treatment within UK law, in...

Employee duty of fidelity and fiduciary obligations: scope, competition and preparatory acts, confidentiality, disclosure, directors’ duties, and remedies including account of profits and the Trade Secrets Regulations 2018

Duty of fidelity Every employee owes their employer a duty of fidelity. This duty is often described as a duty of good faith or loyalty.
