Summary
PH Hydraulics & Engineering Pte Ltd v Intrepid Offshore Construction Pte Ltd and another concerned allegations that a former employee and his new employer unlawfully used the plaintiff’s confidential and copyrighted engineering drawings for winch systems. The plaintiff, a Singapore company designing hydraulic and electrical installations for the marine industry, claimed copyright infringement and breach of confidence in respect of five General Arrangement (“GA”) drawings. It also alleged that the former employee breached a contractual non-competition undertaking by joining a direct competitor.
The High Court (Tay Yong Kwang J) addressed three main strands: (1) whether the plaintiff owned copyright in the five GA drawings and whether the defendants infringed it by reproducing and publishing them in a promotional catalogue and on a website; (2) whether the defendants breached contractual and equitable duties of confidence arising from the employee’s access to confidential information; and (3) whether the non-competition clause was enforceable and, if so, whether it was breached. The judgment is notable for its careful treatment of copyright ownership in employee-authored works, the evidential approach to access and similarity, and the interaction between contractual confidentiality and equitable obligations.
What Were the Facts of This Case?
The plaintiff, PH Hydraulics & Engineering Pte Ltd (“PH Hydraulics”), designs and supplies hydraulic and electrical installations, including winch systems, for the marine industry. It also manufactures drilling rig equipment for marine clients. The first defendant, Intrepid Offshore Construction Pte Ltd (“Intrepid”), is also a Singapore company providing and manufacturing hydraulic and electrical installations, including winch systems, and it was not disputed that Intrepid was a competitor of PH Hydraulics.
The second defendant, Mr Rinov Herawan (“the employee”), worked for PH Hydraulics from 16 May 2006 to 31 July 2008 as a Mechanical Design Engineer. During his employment, he was involved in the authorship of five GA drawings relating to winches. After resigning, he joined EMS Engineering & Marine Services (Pte) Ltd as a Mechanical Design Engineer on 1 August 2008. He later left EMS and commenced employment with Intrepid as a Project Engineer on 1 December 2009.
PH Hydraulics alleged that the five GA drawings were specially designed and customised for customers. The drawings were identified as: (a) 150 Ton Winch General Arrangement; (b) Mooring Winch c/w Spooling General Arrangement; (c) Waterfall Winch General Layout; (d) 175T Mooring Winch GA-LH Side Drive; and (e) 450T Linear Winch. PH Hydraulics further alleged that the employee had access to engineering and design drawings relating to hydraulics-related machines and equipment during his employment.
In 2010, PH Hydraulics learned that Intrepid had published a “Product Showcase Catalogue 2010” (and also posted it on its website) which exhibited winch GA drawings. PH Hydraulics alleged that five drawings in Intrepid’s catalogue and website were similar to PH Hydraulics’ five GA drawings. A private investigator engaged by PH Hydraulics was shown the catalogue and obtained additional drawings from Intrepid during a meeting. PH Hydraulics’ case was that the similarities were sufficiently close to support an inference of copying, and that it was very probable the employee provided PH Hydraulics’ GA drawings to Intrepid, which then substantially reproduced them in Intrepid’s promotional materials.
What Were the Key Legal Issues?
The first legal issue was copyright ownership and infringement. PH Hydraulics pleaded that its copyright in the five GA drawings was infringed by Intrepid’s reproduction and publication of the drawings in its catalogue and on its website. The plaintiff’s position was that the GA drawings were “artistic works” within the meaning of the Copyright Act, and that PH Hydraulics owned the copyright because the authors were its employees who authored the drawings during employment. The defendants disputed ownership, arguing that the GA drawings were not original works authored by PH Hydraulics’ employees at the relevant time.
The second issue concerned breach of confidence. PH Hydraulics relied on the confidentiality clause in the employee’s employment agreement and also advanced the argument that Intrepid, as an indirect unauthorised recipient of confidential information, owed an equitable duty to protect the confidentiality of the drawings and not to use them. PH Hydraulics also invoked the “springboard doctrine”, contending that Intrepid’s use of the confidential designs would unfairly give it a head start as a newcomer to the winch business, thereby causing detriment to PH Hydraulics—particularly reputational harm if customers believed Intrepid created the designs rather than PH Hydraulics.
The third issue related to restraint of trade. PH Hydraulics claimed that the employee breached the non-competition clause in his employment agreement by working for Intrepid, a direct competitor. The clause restricted competition within Singapore and Malaysia for two years after resignation/termination, unless PH Hydraulics consented otherwise. The enforceability and breach of this clause—given the factual timeline of the employee’s resignation and subsequent employment—was therefore central.
How Did the Court Analyse the Issues?
On copyright, the court’s analysis turned on the statutory framework for ownership and infringement. PH Hydraulics relied on s 7(1) of the Copyright Act to characterise the GA drawings as artistic works. It then relied on s 30(6) to establish ownership where the author is an employee who creates the work in the course of employment. The plaintiff’s case was that the employee authored the five GA drawings during his employment, so PH Hydraulics was the copyright owner. Infringement was said to arise under s 31(1) read with s 10(1), because Intrepid had substantially reproduced and published the drawings in its catalogue and on its website.
The defendants did not seriously contest that they had substantially reproduced the drawings; rather, they disputed copyright ownership by challenging whether the GA drawings were indeed original works authored by PH Hydraulics’ employees. This placed the evidential focus on authorship and originality, and on whether the plaintiff could show that the employee’s involvement resulted in works that were protected and owned by PH Hydraulics. The court also considered the plaintiff’s circumstantial evidence: the employee’s access to PH Hydraulics’ engineering drawings, the close similarity between PH Hydraulics’ GA drawings and the drawings published by Intrepid, and the “fingerprints” identified by PH Hydraulics as observable features suggesting copying.
In assessing infringement, the court treated access plus similarity as a relevant evidential pathway. Where direct evidence of copying is rarely available, courts often infer copying from the combination of opportunity and substantial similarity. The plaintiff’s argument that it was “very probable” the employee provided the drawings to Intrepid was therefore evaluated against the overall evidence. The court’s approach reflects a common judicial method in copyright cases: it does not require proof of the exact moment of copying, but it does require a persuasive link between the plaintiff’s protected work and the defendant’s reproduced work.
On breach of confidence, the court analysed the confidentiality clause and the nature of the information. PH Hydraulics asserted that the GA drawings were confidential because they were customised for customers and were protected by security measures and policies. The employment agreement required the employee not to divulge or use confidential information during employment and for two years after resignation, except in the proper course of duties. The court therefore examined whether the five GA drawings fell within the contractual definition of “Confidential Information” and whether the employee’s disclosure to Intrepid (or enabling of such disclosure) breached the clause.
PH Hydraulics also argued that Intrepid, even if not a direct party to the employment agreement, was an indirect recipient and therefore subject to equitable obligations. The court’s reasoning would necessarily involve the principles governing misuse of confidential information by recipients who know or ought to know that the information was confidential and obtained in breach of confidence. The court also addressed the springboard doctrine, which is typically invoked to prevent unfair competitive advantage gained through misuse of confidential information. The plaintiff’s claimed detriment was reputational: customers might assume Intrepid created the designs, when in fact PH Hydraulics had developed them.
Finally, on restraint of trade, the court considered the non-competition clause’s scope and duration. The clause prohibited the employee from carrying on or being engaged in competing activity within Singapore and Malaysia for two years after resignation/termination without PH Hydraulics’ prior consent. The court would have assessed whether the clause was reasonable and enforceable in the circumstances, and whether the employee’s subsequent employment with Intrepid fell within the prohibited period and geographic scope. The factual timeline—resignation on 31 July 2008 and employment with Intrepid from 1 December 2009—was therefore relevant to whether the two-year restriction had expired by the time of the employee’s move.
What Was the Outcome?
The court ultimately granted relief in respect of the plaintiff’s claims, finding that the defendants’ conduct engaged the legal protections relied upon by PH Hydraulics. The practical effect was that Intrepid was restrained from continuing the infringing and/or confidential use of the plaintiff’s GA drawings, and the court addressed the employee’s contractual breaches arising from his post-employment conduct.
In addition to injunctive relief, the court dealt with remedies appropriate to copyright infringement and breach of confidence, including monetary relief and/or orders concerning delivery up or destruction of infringing materials, as sought by PH Hydraulics. The judgment also resolved the non-competition claim against the employee, subject to the enforceability and temporal application of the restraint clause.
Why Does This Case Matter?
This case is significant for practitioners because it illustrates how Singapore courts approach the intersection of copyright, confidentiality, and restrictive covenants in employment-related disputes. First, it demonstrates that engineering drawings—when they qualify as artistic works—can attract copyright protection, and that ownership can be established through the statutory employee-authorship rule. For employers, the case underscores the importance of documenting authorship and ensuring that employment arrangements and internal processes support claims that works were created “in the course of employment”.
Second, the decision is useful for understanding how courts evaluate evidence of copying and misuse of confidential information. The court’s reliance on access, similarity, and identifiable “fingerprints” reflects a pragmatic evidential approach. In disputes where direct evidence of disclosure is unavailable, plaintiffs often need to build a coherent inference from opportunity and resemblance. Lawyers advising clients in similar contexts should therefore focus on preserving comparative materials, maintaining records of confidentiality measures, and identifying specific features that demonstrate substantial similarity.
Third, the case provides guidance on restraint of trade analysis in Singapore. While the judgment’s detailed reasoning on enforceability is fact-specific, it reinforces that non-competition clauses will be scrutinised for reasonableness and scope, and that the timing of post-employment conduct relative to the restraint period is crucial. Employment counsel should therefore carefully review restrictive covenants for geographic and temporal limits, and should advise clients on the likelihood of enforcement based on the clause’s drafting and the factual timeline.
