Summary
Nanofilm Technologies International Pte Ltd v Semivac International Pte Ltd and others concerned a dispute between a Singapore technology company and two former employees, together with a company set up by them. The plaintiff, Nanofilm, manufactures and services Filtered Cathodic Vacuum Arc (“FCVA”) technology products and services. The plaintiff alleged that the first defendant company and the second defendant (a former employee) used the plaintiff’s confidential technical materials and copied its copyright-protected drawings and presentation materials to support the first defendant’s business. The plaintiff also brought employment and tort claims, including breach of contract, breach of confidence, and inducement of breach of contract.
The High Court (George Wei J) analysed the case through multiple causes of action. The court considered whether the defendants’ “Semivac Drawings” and “Semivac Slides” infringed Nanofilm’s copyrights, including whether any “useful article” defence applied and whether the drawings reproduced a substantial part of the plaintiff’s pre-existing technical drawings. The court also assessed whether the second defendant breached his employment contract and whether the defendants breached duties of confidence. Finally, the court addressed whether the third defendant induced the second defendant to breach his contractual obligations. The judgment provides a detailed framework for evaluating copyright infringement in technical drawings and for linking employment-related misuse of materials to confidence and inducement claims.
What Were the Facts of This Case?
Nanofilm is a Singapore company incorporated in May 1999. It operates in the field of vacuum coating technology, specifically FCVA technology, which involves coating materials or products with thin films of metallic, ceramic, or composite substances. The plaintiff’s founder and chief executive officer was Dr Shi Xu, and its senior vice-president was Dr Wei Hao. Although the case did not involve patent infringement, the court accepted that FCVA technology comprises both hardware and software components, and that some hardware components may be generic while others may be designed in-house or tailored to customer needs.
The first defendant, Semivac International Pte Ltd, is also a Singapore company providing products and services in the vacuum industry, including pumps, spare parts, and installation and maintenance services. The second defendant, Xu Yibo, was employed by Nanofilm on 6 April 2000 as an applications engineer and later promoted to manager – production mechanical. In that role, his duties included designing components using software. On 1 August 2014, he was re-designated (described in the judgment as a demotion) to senior engineer – mechanical design. His employment was terminated on 13 January 2016. Importantly, while still employed by Nanofilm, he became a director of the first defendant on 6 October 2008 and remained a director until 11 January 2016.
The third defendant, Hu Lang, was employed by Nanofilm from November 1999 to 4 January 2008 as a senior process engineer, later promoted to senior manager of after-sales technical support. He left Nanofilm and set up the first defendant, becoming its managing director from 6 October 2008. It was not disputed that the second and third defendants had been colleagues for about eight years at the time the third defendant left. After the third defendant’s departure in January 2008, the second defendant remained a full-time employee of Nanofilm and, together with the third defendant, “set up” the first defendant in 2008. The parties disputed whether the second and third defendants jointly decided to set up the company or whether the third defendant persuaded the second defendant to join him shortly after incorporation, but the timing of directorship and management roles was broadly aligned.
Nanofilm’s core factual narrative was that the second defendant did not obtain Nanofilm’s consent to become a director of the first defendant or to perform work for it. Nanofilm further alleged that, while employed, the second defendant created numerous technical drawings for the first defendant using a laptop and CAD software provided by Nanofilm. Some drawings were allegedly created during official working hours, while others were allegedly created outside office hours using Nanofilm’s laptop. Nanofilm’s computer forensics evidence, through Nexia TS Risk Advisory Pte Ltd, recovered 48 “Semivac Drawings” from the second defendant’s laptop. Nexia’s report concluded that the second defendant had in his possession technical drawings belonging to Nanofilm (not drawn by him) and had changed or modified them for the first defendant’s use. Nanofilm maintained that there were many more drawings beyond the 48 recovered.
What Were the Key Legal Issues?
The first major issue was copyright infringement. The court had to determine whether the Semivac Drawings and Semivac Slides infringed Nanofilm’s copyrights. This required the court to examine (i) whether the Semivac Drawings reproduced a substantial part of Nanofilm’s pre-existing technical drawings, and (ii) whether any “useful article” defence applied to the drawings. The “useful article” defence is particularly relevant in technical contexts because drawings may depict functional objects or components, raising questions about the boundary between copyright protection and the protection of ideas, methods, or functional features.
Second, the court had to address Nanofilm’s employment-related claim against the second defendant for breach of contract. This involved assessing the terms of the employment contract and whether the second defendant’s conduct—particularly his involvement with the first defendant while still employed by Nanofilm and his alleged use of Nanofilm’s laptop, software, and technical materials—constituted a breach. The court also had to consider the evidential link between the second defendant’s employment duties, his access to Nanofilm’s materials, and the creation or use of the Semivac materials.
Third, the court had to consider tort claims grounded in breach of confidence and inducement of breach of contract. Specifically, Nanofilm alleged that the first and second defendants breached their duty of confidence owed to Nanofilm. Nanofilm also alleged that the third defendant induced the second defendant to breach his contract. These issues required the court to evaluate whether the information at issue had the necessary quality of confidence, whether it was misused without authorisation, and whether the third defendant’s conduct met the legal threshold for inducement.
How Did the Court Analyse the Issues?
The court’s analysis began with the technical and evidential context. Although the dispute was not about patents, the court considered the nature of FCVA technology to understand what the drawings and slides were doing in the business. The court noted that FCVA technology involves hardware and software, and that some components are generic and available from OEMs. However, the plaintiff’s case was that certain components and configurations were developed in-house and could provide competitive advantages. This matters for copyright and confidence analysis because it affects whether the materials reflect protectable expression (for copyright) and whether they represent confidential information (for confidence).
On copyright infringement, the court focused on the Semivac Drawings. A central question was whether the Semivac Drawings reproduced a substantial part of Nanofilm’s pre-existing technical drawings. In technical drawing disputes, “substantial part” does not require identical copying of every feature; rather, it requires that the copied material reflects a significant portion of the original work’s expression. The court also examined the defendants’ position that most Semivac Drawings were produced without reference to Nanofilm’s copyright materials. Notably, the second defendant admitted that four Semivac Drawings were created using Nanofilm’s existing files, with modifications. That admission was relevant to the court’s assessment of copying and the extent of overlap between the works.
The court also addressed the “useful article” defence. While the judgment extract provided does not reproduce the full reasoning, the structure of the judgment indicates that the court considered whether the drawings were protected as artistic works or whether the protection was limited because the drawings related to functional objects. In copyright law, the useful article defence (as applied in Singapore’s copyright framework) can limit protection where the work’s value lies primarily in its utilitarian function rather than in artistic expression. The court’s approach would have required careful separation between (i) protectable expression in the drawings and (ii) unprotectable functional ideas or methods of construction.
In addition to infringement, the court analysed whether the copyrights in the Semivac Drawings were infringed, again considering substantiality and the useful article defence. The court’s reasoning likely turned on expert and documentary evidence comparing the plaintiff’s drawings with the Semivac drawings, as well as the forensic evidence showing that the second defendant had access to and possessed Nanofilm technical drawings and modified them. The court’s attention to the forensic findings is consistent with the legal requirement to prove copying (or access plus similarity) and to establish that the defendants’ works are derived from the plaintiff’s protected materials.
For the employment contract claim, the court would have examined the contractual obligations of the second defendant, including any restrictions on competing activities, use of company resources, and duties of fidelity or confidentiality. The factual matrix—directorship in the first defendant while still employed by Nanofilm, alleged creation of Semivac drawings using Nanofilm’s laptop and CAD software, and the recovery of drawings from the second defendant’s laptop—provided the factual basis for concluding whether the employment contract was breached. The court’s analysis would have also considered whether the second defendant’s conduct was authorised and whether any consent was obtained.
For breach of confidence, the court had to determine whether the information was confidential, whether it was imparted in circumstances importing an obligation of confidence, and whether the defendants used or disclosed it without authorisation. Technical drawings and process-related materials can qualify as confidential if they are not public and if they convey know-how or trade secrets. The court’s discussion of the FCVA technology and the in-house development elements would have supported an inference that certain drawings and configurations were not merely generic information but represented the plaintiff’s technical know-how. The forensic evidence that the second defendant possessed and modified Nanofilm drawings would have been central to establishing misuse.
Finally, the inducement of breach of contract claim required the court to assess the third defendant’s role. Inducement typically requires more than mere knowledge of a breach; it involves persuading, procuring, or encouraging the breach. The court would have evaluated the disputed narrative about how the first defendant was set up and whether the third defendant actively encouraged the second defendant to act in breach of his contractual duties. The court’s structure indicates it reached a conclusion on liability for inducement, which would have depended on credibility findings and the strength of evidence linking the third defendant’s conduct to the second defendant’s contractual breach.
What Was the Outcome?
Based on the judgment’s structure, the court determined liability across the pleaded causes of action and then addressed remedies and relief. The outcome would have included findings on whether the Semivac Slides and Semivac Drawings infringed Nanofilm’s copyrights, whether the second defendant breached his employment contract, whether the first and second defendants breached duties of confidence, and whether the third defendant induced breach of contract. The court then proceeded to consider appropriate remedies against each defendant, including relief tailored to the specific wrongs found.
Practically, the decision is significant because it connects copyright infringement in technical drawings with employment and confidence duties in a single factual narrative. For a plaintiff, it demonstrates that technical materials can be protected through multiple legal routes—copyright, breach of contract, and breach of confidence—while for defendants it underscores the evidential importance of access, possession, and forensic findings when technical drawings are recovered from personal or company devices.
Why Does This Case Matter?
Nanofilm Technologies International Pte Ltd v Semivac International Pte Ltd is important for practitioners because it illustrates how Singapore courts approach copyright infringement claims involving technical drawings and presentation materials. The case highlights that the analysis is not limited to whether there is some similarity; rather, it requires a structured inquiry into whether a substantial part of the plaintiff’s pre-existing drawings has been reproduced and whether any statutory limitations, such as the useful article defence, apply. This is particularly relevant to industries where drawings depict functional components and where the line between protectable expression and functional design is frequently contested.
From an employment and trade secrets perspective, the case is also a useful authority on how courts may infer breach of contractual duties and breach of confidence from conduct involving access to company resources, creation of competing materials, and forensic evidence of possession and modification. It reinforces that employees who use employer-provided software, laptops, and technical materials to create drawings for a competing venture may face overlapping liability in contract, confidence, and copyright.
For law students and litigators, the judgment’s multi-claim structure provides a roadmap for pleading and proving complex IP and employment-related disputes. It also demonstrates the evidential value of computer forensics in establishing access and copying, and the need for careful expert comparison when technical drawings are alleged to be substantially similar. Even where some elements of technology are generic or available from OEMs, the court’s approach shows that protectable expression and confidential know-how may still exist in the specific configuration, design choices, and presentation of technical information.
