Summary
In Hi-P International Ltd v Tan Chai Hau and others [2020] SGHC 128, the High Court granted an interim injunction restraining two former employees from using or disclosing specified categories of the plaintiff’s trade secrets and confidential information to a competitor group. The application arose from the defendants’ alleged departure from the plaintiff and their subsequent employment with Kunshan Kersen Science & Technology Co, Ltd and its Singapore subsidiary, Kersen Science and Technology (Singapore) Pte Ltd.
The court applied the well-established tripartite test for interim injunctive relief: (i) whether there is a serious question to be tried; (ii) whether damages would be an adequate remedy; and (iii) where the balance of convenience lies. Although the plaintiff’s original injunction prayers were criticised as being too broad, the court allowed amendments to narrow the scope of the restrained information and found that the plaintiff had raised sufficiently serious questions regarding enforceability and breach of confidentiality obligations.
What Were the Facts of This Case?
The plaintiff, Hi-P International Ltd, is a Singapore-incorporated company that describes itself as a manufacturer and seller of components used across wireless telecommunications, consumer electronics, automotive and computing industries. The defendants were all former employees of the plaintiff. The plaintiff alleged that the defendants breached confidentiality, non-solicitation and non-compete clauses in their employment contracts, and that the first defendant induced the second and third defendants to breach their contractual obligations.
On the employment timeline, the first defendant left the plaintiff’s employ in April 2019 and later joined Kunshan Kersen Science & Technology Co, Ltd (“Kunshan Kersen”) in October 2019 as Chief Executive Officer. Kunshan Kersen is a China-incorporated, publicly listed company. The first defendant was also a director of Kersen Science and Technology (Singapore) Pte Ltd (“Kersen Singapore”), a Singapore-incorporated wholly-owned subsidiary of Kunshan Kersen. The second defendant allegedly left the plaintiff in October 2019 and joined Kunshan Kersen sometime between the end of 2019 and early 2020. The third defendant’s last day with the plaintiff was 6 September 2019, and he joined Kunshan Kersen in October 2019 as Tooling Senior Director.
In the suit, the plaintiff claimed that Kunshan Kersen and Kersen Singapore were competitors. It sought damages to be assessed and a permanent injunction, including restraints against revealing trade secrets and confidential information to the competitor group, poaching employees, customers and suppliers, and inducing current and former employees to breach confidentiality, non-solicitation and non-compete clauses. The second defendant was outside Singapore jurisdiction in China and had not yet been served with the writ.
Before the interim injunction hearing, the plaintiff brought three applications: (1) an interim injunction application against the first and third defendants; (2) a further evidence application seeking leave to adduce additional affidavit evidence; and (3) a sealing order application to keep Annex 1 (and associated customer-related names) confidential to non-parties and to redact references in court documents. The extract provided focuses primarily on the further evidence application and the interim injunction analysis, including the court’s concerns about the breadth of the original injunction prayers.
What Were the Key Legal Issues?
The first key issue was whether the plaintiff had established a “serious question to be tried” for interim relief. This required the court to consider, at least at a preliminary level, whether the confidentiality clauses in the first and third defendants’ employment contracts were enforceable and whether the defendants had breached those obligations. A related sub-issue was whether the confidentiality restraints were potentially an unreasonable restraint on trade, requiring a balancing exercise between the employer’s legitimate interests and the employees’ right to earn a living using their skills and experience.
The second key issue concerned the adequacy of damages. Even if there were serious questions to be tried, the court needed to decide whether monetary damages would be an adequate remedy for any misuse or disclosure of confidential information. In trade secret and confidential information cases, the court often considers that once confidentiality is breached, the information may be permanently lost and the resulting harm may extend beyond easily quantifiable losses such as profits.
The third issue was the balance of convenience. The court had to weigh the risk of injustice in granting the injunction against the risk of injustice in refusing it, including whether the restrained information was sufficiently identifiable and protectable, and whether the injunction would operate as a disproportionate restriction on the defendants’ ability to work.
How Did the Court Analyse the Issues?
Before turning to the interim injunction test, the court addressed the plaintiff’s further evidence application. The additional evidence came from an IT department employee, Mr Chen Wang, who gave an affidavit about events in mid-April 2019, shortly before the first defendant left. Mr Chen Wang recalled that the first defendant asked for assistance with his work laptop, including formatting the hard drive, which would cause loss of data and affect the plaintiff’s ability to investigate whether information had been copied. Mr Chen Wang also recalled the first defendant saying he had made a backup copy of data in an external hard drive. However, when the first defendant left, his laptop apparently contained no or few files and he did not hand over any data storage devices.
The court granted leave to adduce this evidence. It found the evidence relevant to the plaintiff’s allegation that the first defendant had taken confidential information when he left, which in turn was relevant to whether the first defendant should be restrained on an interim basis from disclosing the plaintiff’s confidential information. The court also accepted the plaintiff’s explanation that it only discovered the matter on 14 May 2020 during investigations and found the evidence credible.
Turning to the interim injunction application, the court reiterated the governing framework: it would consider (a) whether there is a serious question to be tried; (b) if so, whether damages would be an adequate remedy; and (c) where the balance of convenience lies. The court also noted a procedural point: although the application was treated as an interim injunction, the plaintiff’s prayers did not include the standard wording “until the trial of or determination of this action or further order”. The court indicated that any injunction granted would be taken to include that wording.
Importantly, the court addressed the scope of the injunction prayers. The plaintiff amended prayers 2 and 3 orally to narrow the restraint. The original prayers were considered too wide because they referred generally to “any trade secrets or confidential information”. As amended, the prayers restrained the first and third defendants from using for their own benefit or gain or revealing to Kunshan Kersen or Kersen Singapore specific categories of trade secrets and confidential information listed in the particulars of the statement of claim (and, for the third defendant, also the reply to defence). The court allowed the amendment but cautioned that belated amendments should be avoided in future.
On the serious question to be tried, the court found that the plaintiff had raised serious questions regarding enforceability and breach. The enforceability question depended on whether the confidentiality clause was an unreasonable restraint on trade. The court recognised that this required a difficult balancing exercise: the employer’s legitimate interest in protecting trade secrets and confidential information must be weighed against the former employees’ interests in using skills and experience to earn a living, as well as the wider public interest in favour of competition.
Regarding specificity, the defendants argued that the plaintiff failed to sufficiently particularise the confidential information it sought to protect. The court accepted that specificity is a matter of degree. It agreed that the original wording was too broad, but it was satisfied that, based on the amended wording, most categories of information were sufficiently specific for the defendants to understand what they were prohibited from disclosing.
On breach, the court found the plaintiff’s evidence raised sufficient questions. Mr Chen Wang’s evidence suggested the first defendant had at least the opportunity to copy confidential information before leaving. The court also referred to other evidence that the plaintiff had made a bid for a tender to supply plastic components for speakers. The plaintiff alleged that the second and third defendants were working on the tender, resigned in quick succession during preparations, and then joined Kunshan Kersen. The court noted that the third defendant had not yet identified the person who made him the offer to join Kunshan Kersen, which was relevant to the plaintiff’s inducement allegations. The plaintiff further alleged that it was initially selected for the tender but ultimately lost it to Kunshan Kersen, and that two-thirds of the plaintiff’s project team received calls from Kunshan Kersen soliciting employment.
The court acknowledged that the defendants vigorously contested these allegations and that the plaintiff’s case might ultimately be untrue or coincidental. However, for interim purposes, the court did not require proof on the merits. It held that the plaintiff’s case was not so frivolous or vexatious that it had no chance of succeeding at trial. It also reasoned that if the injunction were refused and the plaintiff succeeded at trial, damages might not be an adequate remedy. Beyond loss of profits, misuse of trade secrets and confidential information could lead to loss of customer connections and goodwill and disruptions to the workforce—harms that are not easily compensable in monetary terms.
Finally, on the balance of convenience, the court considered that granting the amended prayers carried a lower risk of injustice than refusing them. It found it more likely that the information enumerated in the amended prayers—such as customer lists and quotations for projects—constituted protectable confidential information rather than merely the defendants’ skills and knowledge. The court emphasised that once confidentiality is breached, it is permanently lost. On that basis, it granted the amended prayers 2 and 3, subject to two modifications. The extract truncates the remainder of the judgment, but the reasoning shows that the court tailored the injunction to protect identifiable confidential categories while avoiding an overbroad restraint.
What Was the Outcome?
The court granted the interim injunction in substance by restraining the first and third defendants (as amended) from using for their own benefit or gain or revealing specified trade secrets and confidential information to Kunshan Kersen or Kersen Singapore. The injunction was granted on an interim basis pending determination of the action, and the court’s approach reflected a careful narrowing of scope to address concerns about overbreadth and insufficient particularisation.
In addition, the court granted the plaintiff’s further evidence application, allowing the IT employee’s affidavit to be adduced. This evidential development supported the court’s finding that there was a serious question to be tried regarding the alleged copying and misuse of confidential information.
Why Does This Case Matter?
This decision is significant for practitioners because it illustrates how Singapore courts handle interim injunctive relief in employment-related confidentiality disputes, particularly where former employees move to a competitor. The judgment reinforces that while the court will not decide the merits at the interim stage, it will scrutinise whether the employer has identified protectable confidential information with sufficient specificity and whether the restraint sought is proportionate.
From a practical standpoint, the case demonstrates the importance of drafting injunction prayers with appropriate precision. The court expressly agreed that the original prayers were too wide, but it was willing to grant relief once the plaintiff amended the prayers to tie the restraint to particular categories of confidential information. This is a useful drafting lesson for employers seeking interim protection: broad “any confidential information” language is vulnerable, whereas enumerated categories linked to pleadings and particulars are more likely to satisfy the court’s concerns.
Substantively, the judgment also shows the court’s approach to the adequacy of damages in trade secret contexts. The court accepted that harm from confidentiality breaches can include loss of goodwill, customer connections and workforce disruption, which may not be readily quantifiable. This reasoning supports the view that interim injunctions may be appropriate where the confidentiality breach would cause irreparable or hard-to-measure harm.
