Summary
Flamelite (S) Pte Ltd and Others v Lam Heng Chung and Others concerned alleged copyright infringement in technical “preliminary sketches” and related drawings for fire-rated glass doors and screens. The plaintiffs claimed that the defendants’ Swissflame products were substantially similar to, or near exact reproductions of, the plaintiffs’ framing system designs. The dispute arose in a commercial context where the parties were manufacturers and installers in the fire-rated glass door industry, and where design development occurred through licensing, employment, and subsequent independent manufacturing.
The Court of Appeal upheld the dismissal of the plaintiffs’ copyright claims. The court’s reasoning focused on the nature of the works and the infringement test under Singapore copyright law: whether the defendants copied protected expression, and whether any reproduction was “substantial” in the relevant sense. The court also addressed the statutory “non-expert” defence in s 69 of the Copyright Act, which asks whether the allegedly infringing product would appear to persons who are not experts in relation to objects of that kind to be a reproduction of the copyrighted work.
In addition, the case illustrates how courts approach technical drawings and functional designs. While copyright can subsist in drawings, the court will not allow copyright to be used to monopolise ideas, methods, or functional principles that are dictated by engineering constraints. The decision therefore provides a practical framework for assessing infringement where the alleged copying relates to technical construction and where the original drawings are elementary or largely represent non-proprietary principles.
What Were the Facts of This Case?
All parties were involved in manufacturing, selling, and installing fire-rated glass doors and glass screen systems. Historically, before the mid-eighties, most fire-rated doors were imported fully assembled from Europe. From the mid-eighties, Glaverbel, a Belgium company, licensed Flametech to produce steel frames for fire-rated glass screens. This licensing relationship formed part of the background to the plaintiffs’ copyright claims.
Glaverbel claimed copyright in certain artistic works consisting of preliminary sketches for a frame for fire-rated glass screens (the “Glaverbel works”). Those preliminary sketches were created in 1985 by Robert Vanderstukken, an employee of Glaverbel. Although the original sketches were not available at trial because they were lost or destroyed, Glaverbel asserted that the works were illustrated in four test reports prepared for it by the University of Ghent in Belgium. The parties agreed that copyright in the preliminary sketches subsisted in Singapore by virtue of the Copyright (International Protection) Regulations, and that the copyright vested in Glaverbel as employer.
The first and second plaintiffs (Flamelite and Flametech) claimed copyright in preliminary sketches for a frame for both fire-rated glass doors and screens (the “Flamelite works”). These sketches were created in May 1991 by Loke Gim Tay, an employee of Flametech. Loke’s work was described as an improvement on the Glaverbel works, adapting the frame depicted in the Glaverbel works to a fire-proof glass door. Again, the actual preliminary sketches were not produced at trial; instead, shop drawings were tendered to evidence their contents.
In the period from January 1992 to May 1993, the first defendant, Lam, was engaged by Flametech as a subcontractor to fabricate and install fire-rated glass doors and screens. From December 1992 to June 1994, Lam was also engaged by Flamelite. For Lam to perform his work, shop drawings of the Flamelite works were furnished to him. A fourth defendant, Wu Kam Fai, was employed by Flamelite from November 1992 to mid-1994, and his main responsibility was to liaise with subcontractors, including Lam. In June 1994, Flamelite terminated Lam’s engagement.
In August 1994, Lam and his wife incorporated Swissflame Pte Ltd, with Lam holding majority shares and acting as controlling mind. Swissflame manufactured and sold similar fire-rated glass doors and screens. Wu later joined Swissflame in September 1995 as Technical Services Manager. The plaintiffs alleged that Lam, Swissflame, and Wu infringed copyright in the Glaverbel and Flamelite works by producing Swissflame’s framing system, which they claimed was substantially similar or a near exact reproduction of the plaintiffs’ framing system.
What Were the Key Legal Issues?
The Court of Appeal identified two core issues. First, whether there had been infringement of the plaintiffs’ copyright works even though the defendants did not exactly reproduce the plaintiffs’ drawings. This required the court to apply the statutory infringement framework, including the requirement of substantial reproduction and the evidential burden on the plaintiffs to prove copying by the defendants.
Second, the court had to consider the statutory “non-expert” defence under s 69 of the Copyright Act. The defendants argued that the Swissflame products would not appear to persons who are not experts in relation to objects of that kind to be reproductions of the plaintiffs’ artistic works. This issue required the court to interpret how the “notional non-expert” should be used in the infringement analysis, including what comparison should be made between the copyrighted work and the allegedly infringing object.
Although the extract provided does not include the full reasoning, the metadata and the issues framed in the judgment indicate additional sub-issues that were likely addressed: whether the works were protected expression or merely ideas/methods of construction; whether the plaintiffs had locus standi to sue given licensing and assignments; and whether the originality or complexity of the drawings affected the infringement analysis. The court also had to consider whether conscious copying was required, and whether ignorance of copyright could be relevant.
How Did the Court Analyse the Issues?
The Court of Appeal approached infringement by focusing on the legal distinction between protected expression and unprotectable ideas, methods, and functional principles. The plaintiffs’ works were preliminary sketches and related drawings for constructing fire-rated glass doors and screens. The defendants argued that the drawings contained only non-proprietary principles or methods, and that the methods were largely dictated by function and common industry practice. The court accepted that the works related to a method of construction of a functional article, and it was reluctant to allow copyright to be used to create a monopoly over functional solutions.
In assessing whether infringement occurred, the court emphasised that the plaintiffs bore the burden of proving copying. Under the Copyright Act framework, infringement requires that the defendant reproduced a substantial part of the copyrighted work. The court’s analysis therefore turned on whether the Swissflame framing system was substantially similar to the plaintiffs’ protected drawings in a way that amounted to reproduction of expression, rather than merely similarity arising from common engineering constraints. The court also considered the absence of the original preliminary sketches at trial and the reliance on shop drawings and test reports to reconstruct what the copyrighted works contained.
On the evidence, the court noted that the preliminary sketches of both Glaverbel and Flamelite were not produced. For Glaverbel, the works were said to be reflected in University of Ghent test reports. For Flamelite, shop drawings were tendered to evidence the contents of Loke’s preliminary sketches. The court therefore had to evaluate infringement without the original drawings, which made the comparison between the copyrighted works and the defendants’ products more challenging and heightened the importance of identifying what, precisely, constituted the protected expression.
The Court of Appeal also addressed the “non-expert” defence in s 69. The statutory language refers to “persons who are not experts in relation to objects of that kind”. The court considered how a judge should apply this concept: whether the comparison should be made based on an external view of the object or on internal features such as cross-sections. The court’s approach reflects a practical understanding that many technical products are evaluated by how they appear to ordinary observers, not by how they are engineered internally. In this case, the defendants argued that any similarities were not such that a non-expert would perceive the Swissflame product as a reproduction of the plaintiffs’ drawings.
Further, the court considered whether the plaintiffs’ works were sufficiently original or whether they were elementary. The background facts suggested that Vanderstukken’s design was simple and that Loke’s improvements involved engineering modifications such as adding steel capping to protect calcium silicate boards, reinforcing hinge attachment points, and incorporating intumescent strips to fill gaps during a fire. These features are closely tied to functional performance. The court’s reasoning indicates that where the drawings largely reflect functional engineering choices and non-proprietary principles, the scope of copyright protection is correspondingly narrower, and infringement is less likely to be established by pointing to general similarity.
In relation to the Glaverbel works, the trial judge had found that they consisted really of ideas and that Glaverbel’s licensing of Flametech undermined its ability to claim infringement in a way that would amount to “unwitting duplication and double-counting”. While the appeal extract does not reproduce the full appellate treatment of this point, the Court of Appeal’s overall conclusion aligns with the principle that copyright should not be used to extend control beyond what the law protects, particularly where licensing and subsequent development are involved.
Finally, the court considered evidence of access and the likelihood of copying. The agreed facts included that Lam and Wu had access to the plaintiffs’ shop drawings while employed by Flamelite. However, there was also a dispute about whether Loke told Wu that the shop drawings were proprietary and confidential. The court’s infringement analysis would not turn on confidentiality alone, but access is typically relevant to whether copying occurred. Even with access, the plaintiffs still had to show substantial reproduction of protected expression. The court found that the Swissflame product was not substantially similar in the relevant sense, noting differences in materials, dimensions, and other features between the plaintiffs’ works and the defendants’ framing system.
What Was the Outcome?
The Court of Appeal dismissed the plaintiffs’ appeal and upheld the High Court’s decision dismissing the copyright claims. Practically, this meant that Flamelite and the other plaintiffs did not obtain any relief for alleged infringement of the Glaverbel and Flamelite works by Swissflame’s fire-rated glass doors and screens.
The outcome underscores that even where defendants had access to drawings and where products may share broad functional characteristics, plaintiffs must still prove that the defendants reproduced a substantial part of the protected expression. The court’s acceptance of the functional nature of the designs and its application of the s 69 “non-expert” concept were central to rejecting the infringement claim.
Why Does This Case Matter?
Flamelite v Lam Heng Chung is significant for practitioners because it clarifies how Singapore courts approach copyright infringement in technical and functional contexts. The case demonstrates that copyright protection for drawings does not automatically translate into protection for the resulting functional product. Where the drawings embody construction methods and engineering solutions, courts will be cautious not to allow copyright to become a substitute for patent-like exclusivity or to create monopolies over functional ideas.
The decision is also useful for understanding the evidential and analytical steps in infringement claims. Plaintiffs must identify what part of the drawing constitutes protected expression and then show that the defendant’s product reproduces that expression in a substantial way. The case illustrates the challenges where original works are unavailable and the claimant relies on secondary materials such as test reports or reconstructed shop drawings. In such circumstances, the claimant’s burden to prove copying and substantial reproduction becomes more demanding.
Finally, the case provides guidance on the statutory “non-expert” defence under s 69. For defendants, it supports the argument that infringement may fail where the allegedly infringing product would not appear to non-experts to be a reproduction of the copyrighted work. For plaintiffs, it highlights the need to frame infringement by reference to how the protected work would be perceived and understood, rather than relying solely on engineering similarity or general arrangement.
