Interim Injunctions in Patents Cases
The plaintiffs brought proceedings for infringement of their patent. The proceedings were defended. The plaintiffs obtained an interim injunction to prevent the defendants infringing their patent, but they now appealed its discharge by the Court of Appeal.
Held: The questions which applied when looking for an interim injunction in patent infringement cases were no different from those in other cases. The court must first look to the balance of convenience. There was no rule that the court must first look for the prospects of success of either party. The court must be satisfied the claim ‘is not frivolous or vexatious; in other words, that there is a serious question to be tried’. Where there was any doubt about damages being adequate compensation for the grant or withholding of an injunction, the court should preserve the status quo. The judge’s assessment of that balance of convenience was not to be disturbed.
Lord Diplock said of the phrase ‘prima facie case’ that it ‘may in some contexts be an elusive concept’ and ‘the governing principle is that the court should first consider whether, if the plaintiff were to succeed at trial in establishing his right to a permanent injunction, he would be adequately compensated by an award of damages for the loss he would have sustained as a result of the defendant’s continuing to do what was sought to be enjoined between the time of the application and the time of the trial. If damages in the measure recoverable would be [an] adequate remedy and the defendant would be in a financial position to pay them, no interim injunction should normally be granted, however strong the plaintiff’s claim appeared to be at that stage.’
