equired to trigger an account of profits for patent infringement is negligence, 220<br />

whereas for infringement of copyright, 221<br />

primary infringement of design right, 222<br />

<strong>and</strong> infringement of performer’s property rights, 223<br />

an account of profits may be<br />

ordered on a strict liability basis (that is, it is not a defence that the defendant did<br />

not know, <strong>and</strong> had no reason to believe, that copyright or design right existed in<br />

the work or design to which the action relates). As we have seen, a strict liability<br />

approach to restitutionary remedies for a tort is applied in respect of other<br />

proprietary torts. 224<br />

However, it clashes with what appears to be the approach in<br />

respect of the common law intellectual property torts.<br />

(c) Non-proprietary torts<br />

1.23 When one moves to examine the non-proprietary torts, it is much more difficult to<br />

find examples of cases illustrating the award of restitution for a tort. In particular,<br />

‘waiver of tort’ cases that are sometimes cited as illustrations 225<br />

turn out on closer<br />

inspection to be better (or, at least, equally well) interpreted as cases within unjust<br />

enrichment by subtraction (that is, ‘waiver of tort’ is being used in the third sense<br />

set out above). 226<br />

1.24 It is also significant that in Halifax Building Society v Thomas 227<br />

the Court of Appeal<br />

has recently denied a plaintiff a restitutionary claim to the gains made by the tort<br />

of deceit. After earlier pointing out that counsel for the plaintiff had accepted that<br />

“there is no English authority to support the proposition that a wrongdoing<br />

defendant will be required to account for a profit which is not based on the use of<br />

the property of the wronged plaintiff”, Peter Gibson LJ said:<br />

There is no decided authority that comes anywhere near to covering<br />

the present circumstances. I do not overlook the fact that the policy of<br />

law is to view with disfavour a wrongdoer benefiting from his wrong,<br />

the more so when the wrong amounts to fraud, but it cannot be<br />

suggested that there is a universally applicable principle that in every<br />

case there will be restitution of benefit from a wrong. 228<br />

220 Patents Act 1977, s 62(1). The same approach applies to damages.<br />

221 Copyright, Designs <strong>and</strong> Patents Act 1988, s 97(1). A different approach applies to<br />

damages.<br />

222 Copyright, Designs <strong>and</strong> Patents Act 1988, s 233(1). A different approach applies to<br />

damages.<br />

223 Copyright, Designs <strong>and</strong> Patents Act 1988, s 191J(1). A different approach applies to<br />

damages.<br />

224 See para 3.13 above.<br />

225 On deceit see, for example, Hill v Perrott (1810) 3 Taunt 274, 128 ER 109; Billing v Ries<br />

(1841) Car & M 26, 174 ER 392; Kettlewell v Refuge Assurance Co [1908] 1 KB 545,<br />

affirmed [1909] AC 243. On intimidation see, for example, Astley v Reynolds (1731) 2 Str<br />

915, 93 ER 939; Universe Tankships Inc of Monrovia v ITWF [1983] 1 AC 366. On inducing<br />

breach of contract see, for example, Lightly v Clouston (1808) 1 Taunt 112, 127 ER 774;<br />

Foster v Stewart (1814) 3 M & S 191, 105 ER 582.<br />
