“'Euro-defences' of this kind have been deployed by alleged infringers of intellectual property rights for many years, and the English courts have varied in the robustness with which they approach them. The dilemma is that litigation devalues intellectual property rights, by increasing the cost and delay associated with their enforcement. It may also serve to confer on the alleged infringer a temporary immunity or an improvement of his bargaining power in settlement negotiations, to which he will turn out not to be entitled. The effect can often extend beyond the parties or transactions in issue, to many other cases in which similar questions might be raised. These factors mean that defences like the present one must be scrutinised with some care, even if that requires a certain amount of analysis. On the other hand, a defendant must be allowed to go to trial if it has raised a triable issue of fact which is relevant in point of law. For obvious reasons, this is especially important when the case is founded on fundamental principles of the European Union such as the free movement of goods and undistorted competition.”
“I do not regard it as clear that a breach of Art. 81 can only constitute a claim, not a defence, in any circumstances. It seems to me well arguable that to be able to prove that a relevant agreement is in breach of Art. 81 would give a defendant a stronger basis for saying that the claimant does not have legitimate reasons under s. 12(2). I do not decide that the defendant’s position on either of these points is necessarily right as a matter of law, even if the necessary facts can be established. But it does seem to me that the points are sufficiently arguable for it to be wrong to strike these paragraphs out of the Defence.”
