Costs – Orders for costs. It was common ground that, overall, the defendants had been successful in previous proceedings (see[2015] All ER (D) 233 (Apr)) and that the starting point was that they were entitled to their costs. The present proceedings concerned the extent to which a deduction should be made from those costs to reflect issues on which the defendants had been unsuccessful and the amount the claimants should be ordered to pay on account of the defendants' costs. The Patents Court held that, in the circumstances, the claimants would be ordered to pay 75% of the defendants' costs. As to payment on account, a reasonable figure was 55%, that was 55% of 75% of the defendants' total bill.
