“(1) If the injury to the plaintiff's legal rights is small, (2) And is one which is capable of being estimated in money, (3) And is one which can be adequately compensated by a small money payment, (4) And the case is one in which it would be oppressive to the defendant to grant an injunction…”
“[t]here may be cases in which, though the four above-mentioned requirements exist, the defendant by his conduct, as for instance, hurrying up his buildings so as if possible to avoid an injunction, or otherwise acting with reckless disregard to the plaintiff’s rights, has disentitled himself from asking that damages may be assessed in substitution for an injunction.”
“In law it rests upon the hypothesis that what has to be considered in measuring the loss a patentee sustains through infringement is some bargain struck between some abstract licensor and some abstract licensee uncontaminated by the qualities of the actual actors. But this is not so. The ‘willing licensor’ and ‘willing licensee’ to which reference is often made…is always the actual licensor and the actual licensee who, one assumes, are each willing to negotiate with the other – they bargain as they are, with their strengths and weaknesses, in the market as it exists. It is one thing (and legitimate) to say of a particular bargain that it was not comparable or made in comparable circumstances with the bargain which the court is endeavouring to assume, so as, for example, to reject as comparable a bargain made in settlement of litigation. It is quite another thing to reject matters (other than any doubt over the validity of the patent itself) of which either side, or both sides, would necessarily and relevantly take account when seeking agreement”
“are evidently not considered to provide any guidance as to what a right is worth. In contrast, the Courts do, as it seems to me, have regard to the circumstances in which the individual parties were placed at the time of the hypothetical negotiation. It is implicit in the passage from Vos J’s judgment in the Stadium Capital Holdings case that he considered that “the objective factors with which [the parties] were faced” are relevant. Earlier cases point in the same direction. For example, in Wrotham Park Estate Co Ltd v Parkside Homes Ltd[1974] 1 WLR 798 , where houses had been built in breach of a restrictive covenant, damages were calculated, not in the abstract, but by reference to the profit that the defendant would have expected to make from its development. In Sinclair v Gavaghan[2007] EWHC 2256 (Ch) , where the defendants had trespassed on a piece of land referred to as “the Red Triangle” when gaining access to a plot beyond (“the Yellow Land”) which they were developing, Patten J similarly took account of circumstances particular to the defendants: he had regard both (a) to the significance of the trespass in the context of the defendants’ development of the Yellow Land and (b) to the fact that they owned neighbouring land (“No. 21”). In Field Common Ltd v Elmbridge BC[2009] 1 P&CR 1 , Warren J said (in paragraph 78) that the hypothetical negotiation is “designed to establish the value of the wrongful use to the defendant and not some objective figure as between hypothetical persons negotiating for a hypothetical licence” and that the negotiation “would be one between the actual parties, albeit that they are to be treated as parties willing to deal with each other with a view to reaching a reasonable result”.”
