Trade Secrets vs Defamation: When Confidentiality and Reputation Collide

When a former employee or business partner is accused of stealing trade secrets, the allegations can be devastating to their professional reputation. Conversely, legitimate trade secret claims may require disclosing information that the accused party considers defamatory. This guide navigates the complex intersection of confidential information law and defamation.

When Trade Secret Allegations Become Defamatory

Accusing someone of stealing trade secrets implies dishonesty and potential criminality. Such allegations can be defamatory if:

• The accusation is false — the individual did not misappropriate confidential information
• The statement is published to third parties — including colleagues, industry contacts, or the public
• The statement causes serious harm to the individual's reputation under section 1 of the Defamation Act 2013

Common scenarios include employers sending letters to a departing employee's new employer alleging misappropriation, or making statements in industry circles about an individual's alleged theft of proprietary information.

Defences Available to the Accuser

An employer or business partner who makes trade secret allegations may rely on several defamation defences:

• Truth — if the individual genuinely did misappropriated trade secrets, the truth defence under section 2 is a complete answer
• Qualified privilege — communications to parties with a legitimate interest (e.g., the new employer, regulators, legal advisers) may attract qualified privilege, provided there is no malice
• Litigation privilege — statements made in connection with legal proceedings are protected by absolute privilege

The Springboard Doctrine

The "springboard doctrine" (from Terrapin v Builders' Supply) allows courts to grant injunctions preventing someone from using confidential information as a "springboard" for competitive advantage. In defamation terms:

• A public statement that an ex-employee "used our trade secrets to set up a competing business" could be defamatory if false
• But if the employer has obtained a springboard injunction, this strongly supports a truth defence
• The outcome of confidential information proceedings is highly relevant evidence in any parallel defamation claim

Criminal Implications

Accusing someone of trade secret theft may also imply criminal conduct (fraud, theft, or breach of the Trade Secrets (Enforcement, etc.) Regulations 2018). Allegations of criminal conduct are treated as particularly serious in defamation law and may support a claim for aggravated damages.

Parallel Proceedings

It is common for trade secret and defamation claims to run alongside each other. Practical considerations include:

1. Evidence gathered in trade secret proceedings (disclosure, witness statements) may be relevant to defamation claims and vice versa
2. Courts may order that claims be heard together or sequentially to avoid inconsistent findings
3. Settlement of one claim may affect the other — a settlement acknowledging no trade secret misappropriation undermines the truth defence in defamation
4. Legal professional privilege must be carefully managed across both sets of proceedings
