“The basic approach in the assessment of damages for any breach, whether the obligation of confidentiality is contractual or equitable, is to ascertain the value of the information which the Defendant took: Seager v Copydex (No.2)[1969] 1 WLR 809 at 813. That leads to another issue of complexity: the basis of valuing what the Defendant took. There are various ways of doing this; and what is appropriate is likely to depend on the quality of the information taken and whether its value is susceptible to measurement by analogy to a market standard or not.”
“…a notional royalty (or its capitalised value) is commonly awarded as damages for breach of a duty not to misuse confidential information, whether that duty arises from contract or from equitable doctrines: Seager v Copydex Ltd (No 2)[1969] 1 WLR 809 , 813; Force India Formula One Team Ltd v 1 Malaysia Racing Team Sdn Bhd[2012] RPC 29 , paras 383-387, 424, approved without consideration of this point,[2013] EWCA Civ 780 ;[2013] RPC 38 . This is not because of some principle peculiar to equitable relief. Nor is it because the claims were in reality for restitution. These were expressed to be, and in fact were awards of compensatory damages.”
“[84] There have also been cases in which negotiating damages have been treated as available at common law in cases of breach of contract. An example is the case of Vercoe v Rutland Fund Management Ltd[2010] EWHC 424 (Ch) ; [2010] Bus LR D1414 which also concerned the breach of a joint venture agreement, where the Defendants used the information provided by the claimants about a commercial opportunity without including them in the transaction. There were breaches both of a confidentiality agreement and of an equitable duty of confidentiality. It was agreed that damages should be assessed on the basis of a hypothetical release fee. In effect, the court awarded damages based on the commercial value of the information which the Defendants misused, as in a number of earlier cases concerned with breach of confidence. These cases can be understood as proceeding on the footing that the result of the breach of contract was that the claimants lost a valuable opportunity to exercise their right to control the use of the information… [91] The use of an imaginary negotiation can give the impression that negotiation damages are fundamentally incompatible with the compensatory purpose of an award of contractual damages. Damages for breach of contract depend on considering the outcome if the contract had been performed, whereas an award based on a hypothetical release fee depends on considering the outcome if the contract had not been performed but had been replaced by a different contract. That impression of fundamental incompatibility is, however, potentially misleading. There are certain circumstances in which the loss for which compensation is due is the economic value of the right which has been breached, considered as an asset. The imaginary negotiation is merely a tool for arriving at that value. The real question is as to the circumstances in which that value constitutes the measure of the claimant’s loss. [92] As the foregoing discussion has demonstrated, such circumstances can exist in cases where the breach of contract results in the loss of a valuable asset created or protected by the right which was infringed, as for example in cases concerned with the breach of a restrictive covenant over land, an intellectual property agreement or a confidentiality agreement. Such cases share an important characteristic with the cases in which Lord Shaw’s “second principle” and Nicholls LJ’s “user principle” were applied. The claimant has in substance been deprived of a valuable asset, and his loss can therefore be measured by determining the economic value of the asset in question. The Defendant has taken something for nothing, for which the claimant was entitled to require payment. [93] It might be objected that there is a sense in which any contractual right can be described as an asset, or indeed as property. In the present context, however, what is important is that the contractual right is of such a kind that its breach can result in an identifiable loss equivalent to the economic value of the right, considered as an asset, even in the absence of any pecuniary losses which are measurable in the ordinary way. That is something which is true of some contractual rights, such as a right to control the use of land, intellectual property or confidential information, but by no means of all. For example, the breach of a non-compete obligation may cause the claimant to suffer pecuniary loss resulting from the wrongful competition, such as a loss of profits and goodwill, which is measurable by conventional means, but in the absence of such loss, it is difficult to see how there could be any other loss. [94] It is not easy to see how, in circumstances other than those of the kind described in paras 91—93, a hypothetical release fee might be the measure of the claimant’s loss. It would be going too far, however, to say that it is only in those circumstances that evidence of a hypothetical release fee can be relevant to the assessment of damages. If, for example, in other circumstances, the parties had been negotiating the release of an obligation prior to its breach, the valuations which the parties had placed on the release fee, adjusted if need be to reflect any changes in circumstances, might be relevant to support, or to undermine, a subsequent quantification of the losses claimed to have resulted from the breach. It would be a matter for the judge to decide whether, in the particular circumstances, evidence of a hypothetical release fee was relevant and, if so, what weight to place upon it. However, the hypothetical release fee would not itself be a quantification of the loss caused by a breach of contract, other than in circumstances of the kind described in paras 91—93 above.”
