Giving judgement in the Court of Appeal case Shenzhen Senior Technology Material Co Ltd v Celgard, LLC  EWCA Civ 1293 Lord Justice Arnold has shone a further light on the UK Trade Secrets (Enforcement, etc.) Regulations 2018 (SI 2018/597) [TSR].
Dividing his analysis into pre/post the EU Trade Secrets Directive (EU Dir. 2016/943) Arnold LJ noted, “under English law prior to the implementation of the Trade Secrets Directive, trade secrets constituted a particular category of confidential information. The principal distinguishing characteristic of trade secrets, as opposed to other forms of confidential information, was that a former employee could be restrained from using or disclosing their former employer’s trade secrets after the termination of the employment”. 
“The Trade Secrets Directive harmonises the protection against the unlawful acquisition, use and disclosure of trade secrets in the European Union. It is not an exhaustive harmonisation: Article 1(1) provides that Member States may provide for more far-reaching protection than that required by the Directive provided that compliance with a number of provisions of the Directive is ensured. Thus the Directive provides both a floor and a ceiling.”
Moreover, it was noted that whilst TSR might implement the Trade Secrets Directive, it does not transpose Articles 3, 4 or 5 of the Directive.
Turning to the “curious provision” of Regulation 3 Wider Protection, Arnold LJ surmised “… it appears to be primarily intended to ensure that, if and in so far as English law prior to the implementation of the Trade Secrets Directive was more favourable to the trade secret holder…then that greater level of protection shall continue to be available…”.
Conversely it was noted that Regulation 3 does not appear to address the position if the Directive confers greater protection than English law did previously. In such a situation the solution advocated by Arnold LJ would be to interpret and apply TSR consistently with the Directive and again offer the trade secret holder the higher protection.
Despite its somewhat inauspicious start at IPEC it seems clear that our Judges are starting to get to grips with TSR.
