Summary
Main-Line Corporate Holdings Ltd v United Overseas Bank Ltd and Another concerned an interim payment application in a patent infringement action where the plaintiff had elected an account of profits against the first defendant. After the trial judge found that the Singapore patent was infringed (and ordered an inquiry into profits or damages), the plaintiff sought an interim payment on the basis that the first defendant had received a specified sum of “commissions” from a related system provider. The plaintiff argued that this commission figure represented the minimum profits the first defendant would be liable to account for.
The High Court (Lee Seiu Kin J) dismissed the plaintiff’s application for interim payment. Although the first defendant did not dispute receipt of the commission sum, the court held that interim payment requires the plaintiff to satisfy the court that there is an amount below which the assessment of profit will not go. The first defendant was entitled to adduce evidence of costs legitimately deductible in computing profits for an account of profits, and the affidavits relied upon by the plaintiff were framed as rough estimates for election purposes rather than as a conceded computation of net profit with a guaranteed floor.
What Were the Facts of This Case?
The plaintiff, Main-Line Corporate Holdings Ltd, is a company incorporated in Ireland. It was the registered proprietor in Singapore of patent no 86037 (W/O 01/04846) entitled “Dynamic Currency Conversion for Card Payment Systems” (the “Patent”). The first defendant, United Overseas Bank Ltd (“UOB”), is a bank incorporated in Singapore. The second defendant, First Currency Choice Pte Ltd, provided a system known as the FCC System, which generated income for UOB.
The plaintiff’s substantive claim was for damages arising from infringement of the Patent by UOB in relation to the operation of the FCC System. The trial was heard by Tay Yong Kwang J (“Tay J”). In a judgment dated 21 December 2006, Tay J found that the Patent was infringed by the defendants. As to remedies, Tay J ordered an inquiry by the Registrar on damages or an account of profits, with the plaintiff required to elect its remedy. The plaintiff elected an account of profits against UOB and elected damages against the second defendant.
The present proceedings concerned only the plaintiff’s claim against the first defendant for an account of profits. On 14 May 2009, the plaintiff filed summons no 2556 of 2009 under Order 29 seeking an interim payment. The plaintiff prayed that UOB pay S$3,135,236.40 (or such sum as the court deemed just) into court as an interim payment to the account of UOB’s profits in respect of the infringement claim.
The factual foundation for the interim payment application was an affidavit filed by the plaintiff’s deponent, Declan Gerard Barry (“Declan”), on 14 May 2009. Declan referred to an earlier affidavit by UOB’s officer, Gan Ai Im (“Gan”), filed on 6 March 2008. In Gan’s affidavit, an exhibit (marked “GAI-1”) showed that UOB had received S$3,135,236.40 from the second defendant as “commissions” for the period May 2002 to December 2007. The plaintiff’s position was that this commission sum represented the minimum amount that UOB would be liable to account for after final assessment.
What Were the Key Legal Issues?
The central legal issue was the threshold for granting an interim payment under Order 29 in the context of an account of profits. Interim payment is not a substitute for the final inquiry; it is intended to provide a cash payment on account where the court can be satisfied that there is a sufficiently clear and safe basis for the amount ordered. The court had to determine whether the plaintiff had discharged the burden of showing that there was an amount below which the assessment of profits would not go.
A second issue concerned the proper computation of “profits” for an account of profits. Even if UOB received a gross commission amount, the court needed to consider whether that figure necessarily equated to profits. The first defendant argued that costs and expenses incurred in operating the FCC System (and in running it in tandem with UOB’s broader credit card business) had to be deducted to arrive at net profits. The plaintiff, by contrast, relied on figures and statements in affidavits that it said supported a floor for profits.
Finally, the court had to assess whether the evidence relied upon by the plaintiff—particularly the commission figure and related computations—was sufficiently reliable and appropriately framed for the interim payment stage. The question was whether the affidavits amounted to a concession of net profit or whether they were merely rough estimates designed to allow the plaintiff to make an election between damages and an account of profits.
How Did the Court Analyse the Issues?
Lee Seiu Kin J began by setting out the procedural and evidential context. The interim payment application followed a trial finding of infringement and an order for inquiry into profits or damages. The plaintiff had elected an account of profits against UOB, so the interim payment had to be assessed in relation to the profits UOB would be required to account for. The judge then examined the affidavits relied upon by the plaintiff, focusing on the commission figure and the computations presented by UOB’s witnesses.
It was not disputed that UOB received S$3,135,236.40 from the second defendant as commission. However, the first defendant’s response was that an account of profits requires consideration of costs incurred in relation to the transaction that generated the commission. This argument was persuasive to the assistant registrar, who had ordered a lower interim payment of S$1,962,424.30 into court. The plaintiff appealed, contending that the assistant registrar had misapplied the evidence and should have ordered the full commission sum.
The judge then scrutinised the plaintiff’s reliance on a statement in the affidavit of UOB’s vice president, Cheang Kok Chew (“Cheang”). Cheang’s affidavit filed on 2 June 2009 exhibited a table marked “CKC-1” and stated that the estimated profits earned by UOB from the operation of the FCC System during May 2002 to December 2007 was S$1,962,424.30. The assistant registrar had treated this as supporting the interim payment amount. On appeal, however, the first defendant argued that the statement was misinterpreted and that the context and purpose of the earlier figures mattered.
Lee Seiu Kin J accepted that context was crucial. The judge explained that Gan’s earlier affidavit (filed 6 March 2008) was prepared in response to the plaintiff’s pre-election discovery application. Gan’s affidavit did not concede that the net profit computation was the final or definitive cost-and-profit analysis. Instead, Gan had expressly described the figures as a computation of “net profits” generated from the FCC System, derived by applying UOB’s expense/income ratios from UOB’s annual reports to the commission revenue. The judge emphasised that this method was a rough estimate intended to provide the plaintiff with adequate information to make its election.
In particular, the judge noted that Gan had made clear that UOB did not have a specific amount or breakdown of costs associated with the FCC System. Gan’s computation therefore used expense/income ratios for UOB’s broader operations to derive an estimated net profit. This was not the same as a concession that the total cost to UOB was the specific figure described as “net profit” in the exhibit. The judge also observed that Cheang’s later affidavit (2 June 2009) was made in response to Declan’s affidavit supporting the interim payment application. Cheang reiterated the commission receipt but explained that UOB incurred costs and expenses to run the FCC System alongside its overall system, while also acknowledging that UOB did not have a specific breakdown of costs associated with the FCC System.
Crucially, the judge treated Cheang’s statement about estimated profits as part of a revised table and corrections to earlier exhibits, rather than as a definitive computation of profits that would establish a guaranteed floor for interim payment. Cheang further indicated that the issues of relevant costs and expenses, and the amounts to be deducted from gross revenue to compute profits for which UOB should account, would be fully canvassed at the hearing. This reinforced the point that the final profit computation was not yet determined.
Against this evidential backdrop, the judge articulated the legal requirement for interim payment: the plaintiff must satisfy the court that there is an amount below which the assessment of profit will not go. The judge held that the plaintiff had not met this requirement. The first defendant was entitled to provide evidence of all costs related to the establishment and operation of the FCC System that may legitimately be deducted from the gross commission to arrive at the profits it would be liable to account for. The plaintiff’s reliance on expense/income ratio-based estimates did not establish that the net profit could not fall below a certain level once proper costs were considered.
Accordingly, Lee Seiu Kin J concluded that the assistant registrar had erred in ordering interim payment on the basis of the estimated profits figure. The judge allowed the first defendant’s appeal, set aside the interim payment order, and dismissed the plaintiff’s appeal.
What Was the Outcome?
The High Court allowed the first defendant’s registrar’s appeal (RA 228/2009) and set aside the assistant registrar’s order requiring UOB to pay S$1,962,424.30 into court as an interim payment. The plaintiff’s registrar’s appeal (RA 225/2009) was dismissed, meaning the plaintiff did not obtain the interim payment it sought.
Practically, the decision meant that the plaintiff had to wait for the final inquiry into profits (or further procedural steps in the account of profits) rather than receiving a cash payment on account based on the commission and rough net profit estimates.
Why Does This Case Matter?
This decision is significant for practitioners because it clarifies the evidential and substantive threshold for interim payments in cases involving an account of profits. Even where infringement has been found and the plaintiff has elected an account of profits, the court will not automatically treat gross receipts (such as commissions) as profits for interim payment purposes. The court requires a reliable basis to conclude that the eventual profit assessment will not fall below the interim amount sought.
Main-Line Corporate Holdings also illustrates the importance of the purpose and context of affidavit evidence. Figures generated for election purposes—particularly where they are derived from expense/income ratios due to the absence of a specific cost breakdown—may not be sufficient to establish a “floor” for interim payment. The court’s reasoning underscores that interim payment is a discretionary procedural remedy that must be grounded in evidence capable of supporting a conservative and defensible estimate of profits.
For law students and litigators, the case provides a useful framework for preparing interim payment applications: counsel should anticipate that defendants will argue for deduction of legitimate costs and will resist interim orders unless the plaintiff can show, with credible evidence, that the net profit computation cannot be materially lower than the interim sum. The decision therefore informs both litigation strategy and the drafting of affidavit evidence in intellectual property and commercial disputes where accounts of profits are sought.
