Summary
PH Hydraulics & Engineering Pte Ltd v Intrepid Offshore Construction Pte Ltd and another ([2012] SGHC 133) concerned a former employee’s movement between competing marine engineering companies and the alleged misuse of the plaintiff’s winch design documentation. The plaintiff brought claims for copyright infringement and breach of confidence in relation to five General Arrangement (“GA”) drawings for winches. It also sought to restrain the second defendant’s post-employment activities by relying on a non-competition clause in his employment agreement.
The High Court (Tay Yong Kwang J) addressed, in substance, whether the plaintiff owned copyright in the drawings, whether the defendants had infringed that copyright by reproducing and publishing the drawings, and whether the drawings were protected confidential information. The court also considered the enforceability and breach of the contractual non-competition obligation against the second defendant, and the appropriate remedies, including injunctive relief and monetary relief.
What Were the Facts of This Case?
The plaintiff, PH Hydraulics & Engineering Pte Ltd (“PH Hydraulics”), is a Singapore-incorporated company that designs and provides hydraulic and electrical installations for the marine industry, including winch systems. It also manufactures drilling rig equipment for the marine industry. The first defendant, Intrepid Offshore Construction Pte Ltd (“Intrepid”), is also Singapore-incorporated and provides and manufactures hydraulic and electrical installations, including winch systems, and was not disputed to be a competitor of PH Hydraulics in the marine industry.
The second defendant, Mr Rinov Herawan, 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 (“EMS”) on 1 August 2008 as a Mechanical Design Engineer. He later left EMS and commenced employment with Intrepid as a Project Engineer on 1 December 2009.
PH Hydraulics alleged that it had copyright in five specific GA drawings (the “five GA drawings”): (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. These drawings, PH Hydraulics said, were designed and customised for particular customers, and the drawings were part of its protected intellectual property and confidential engineering know-how.
In 2010, PH Hydraulics learned that Intrepid had published a promotional catalogue titled “Product Showcase Catalogue 2010” (and also posted it on its website). The catalogue exhibited five general arrangement drawings of winches that were said to be similar to PH Hydraulics’ five GA drawings. The catalogue described the drawings as: (a) Electric Drive Winch 150 T SWL; (b) Constant Tension Winch 30 T SWL; (c) Waterfall Type Winch 100 T SWL; (d) A & R Winch 150 mT; and (e) Linear Winch 500 T. PH Hydraulics hired a private investigator who was shown the catalogue and obtained additional drawings from Intrepid during a meeting at Intrepid’s premises.
What Were the Key Legal Issues?
The first major issue was copyright ownership and infringement. PH Hydraulics pleaded that the five GA drawings were “artistic works” within the meaning of s 7(1) of the Copyright Act. It relied on s 30(6) of the Copyright Act to argue that because the authors were its employees who authored the drawings during their employment, PH Hydraulics was the owner of the copyright. PH Hydraulics then alleged infringement under s 31(1) read with s 10(1), contending that Intrepid had substantially reproduced and published the drawings in its catalogue and on its website.
The second issue concerned breach of confidence. PH Hydraulics argued that the GA drawings were confidential because the winch designs were customised for clients and because PH Hydraulics had implemented security measures and policies to safeguard confidentiality. It alleged that the second defendant breached the confidentiality clause in his employment agreement by disclosing the drawings to Intrepid. PH Hydraulics further argued that Intrepid, as an indirect unauthorised recipient, owed an equitable obligation to protect the confidentiality and could not use the drawings for its promotional materials. PH Hydraulics also invoked the “springboard doctrine”, contending that allowing Intrepid to use the confidential information would give it an unfair head start and cause detriment to PH Hydraulics, including reputational harm if customers believed Intrepid had created the designs.
The third issue was contractual restraint of trade, specifically the non-competition clause. PH Hydraulics claimed that the second defendant breached the non-competition clause by working for Intrepid, a competitor, within the restricted period. The clause prohibited the second defendant from carrying on or being engaged in competing activity within Singapore and Malaysia for two years after resignation/termination, absent the company’s prior consent.
How Did the Court Analyse the Issues?
On copyright, the court’s analysis focused on whether PH Hydraulics could establish ownership and whether the defendants’ conduct amounted to infringement. PH Hydraulics’ position was that the five GA drawings were original artistic works and that, as the drawings were authored by its employees during employment, PH Hydraulics owned the copyright by operation of s 30(6) of the Copyright Act. The court also had to consider the defendants’ challenge to ownership. Intrepid and the second defendant did not deny that the drawings were substantially reproduced and published in the catalogue and on the website, but they disputed that the drawings were the original work of PH Hydraulics’ employees at the relevant time.
In addressing infringement, the court considered the evidential framework often used in copyright cases where direct copying is difficult to prove. PH Hydraulics relied on two key strands: first, the second defendant’s access to the drawings during his employment; and second, the close similarity between PH Hydraulics’ drawings and the drawings published by Intrepid. PH Hydraulics also pointed to what it described as “fingerprints” in the drawings, supporting an inference that the published drawings were derived from PH Hydraulics’ GA drawings rather than independently created. The court treated these similarities as relevant to whether the reproduction was substantial and whether copying was likely.
The defendants also raised an “industrial application” argument, essentially suggesting that if articles were manufactured from the drawings, copyright would not be infringed because the drawings had been industrially applied for sale or hire. However, the defendants did not pursue this defence in their closing submissions, which meant the court’s focus remained on the core questions of ownership, copying, and infringement rather than on the industrial application limitation.
On breach of confidence, the court examined whether the information was confidential and whether there was unauthorised disclosure and/or use. The plaintiff emphasised that the GA drawings were not generic engineering documents but were customised for clients and therefore carried commercial value. The court also considered the contractual confidentiality clause, which required the second defendant not to divulge or use confidential information during employment and for two years after resignation/termination, and required surrender of notes and memoranda containing confidential information. The existence of contractual protections, while not determinative on its own, supported the plaintiff’s contention that the drawings were treated as confidential within the company.
The court further analysed whether Intrepid could be liable as an indirect recipient. PH Hydraulics argued that even if it did not directly hand over the drawings to Intrepid in a fully authorised manner, Intrepid would still be bound by an equitable obligation to protect confidentiality if it received the information in circumstances that made it improper to use it. The court’s reasoning would have required it to assess the likelihood of disclosure by the second defendant, the nature of the similarities between the drawings, and whether Intrepid’s use in a promotional catalogue and on its website was consistent with any legitimate acquisition or independent creation.
In relation to the springboard doctrine, the court considered the principle that a wrongdoer should not be allowed to gain an unfair head start from misuse of confidential information. PH Hydraulics’ claimed detriment included reputational harm and the risk that customers would assume Intrepid had designed the winches when, in PH Hydraulics’ view, Intrepid had copied PH Hydraulics’ designs. The court’s approach would have been to determine whether the circumstances justified injunctive relief to prevent ongoing or future misuse and whether damages or other monetary remedies were warranted based on proof of loss.
Finally, on the non-competition clause, the court had to consider whether the clause was enforceable and whether the second defendant’s employment with Intrepid fell within the prohibited conduct. The clause restricted the second defendant from competing within Singapore and Malaysia for two years after resignation/termination without the company’s prior consent. The court would have assessed the factual timeline: the second defendant resigned on 31 July 2008 and started work at Intrepid on 1 December 2009, which fell within the two-year post-termination period. The court also had to consider whether Intrepid was indeed a competitor and whether the second defendant’s role amounted to being “engaged in any activity or business” in competition with PH Hydraulics’ business.
While the extract provided does not include the court’s final reasoning in full, the structure of the pleaded case indicates that the court’s analysis would have integrated both contractual interpretation and the broader legal framework governing restraints of trade. In Singapore, restraints are generally assessed for reasonableness and legitimate protection of proprietary interests, and the court would have considered whether the geographic and temporal limits (Singapore and Malaysia; two years) were proportionate to the employer’s legitimate interests in confidentiality and goodwill.
What Was the Outcome?
Based on the pleaded claims and the court’s engagement with copyright infringement, breach of confidence, and the non-competition clause, the practical effect of the decision was to determine whether PH Hydraulics was entitled to injunctive relief restraining further use and publication of the infringing drawings and confidential information, and whether monetary relief was appropriate. The court also had to decide whether the second defendant’s post-employment conduct warranted damages for breach of the employment agreement.
Although the provided extract is truncated and does not reproduce the final orders, the case is commonly cited for its treatment of the evidential inference of copying (access plus similarity), the protection of confidential engineering drawings, and the enforceability of post-employment non-competition obligations tied to legitimate business interests. The outcome therefore would have been significant both for IP enforcement against competitors and for employers seeking to protect design documentation through confidentiality and restraint clauses.
Why Does This Case Matter?
This decision matters because it illustrates how Singapore courts approach disputes where engineering drawings and design documentation are alleged to have been copied and repurposed by a competitor after a key employee leaves. For practitioners, the case highlights the importance of (1) establishing copyright ownership through statutory provisions on employee authorship, (2) proving infringement through a combination of access and substantial similarity, and (3) framing confidentiality claims with clear evidence of confidential character and contractual safeguards.
From a litigation strategy perspective, the case also demonstrates the interplay between copyright and breach of confidence. Even where copyright ownership or infringement may be contested, breach of confidence can provide an alternative route to relief, particularly where the information is commercially valuable, customised, and protected by internal policies. The springboard doctrine, in particular, underscores that courts may be willing to grant injunctive relief to prevent unfair competitive advantage derived from misuse of confidential information.
For employers and HR counsel, the non-competition aspect is equally instructive. The case reinforces that post-employment restraints are not merely formal contractual terms; they must be assessed in context, including duration, geographic scope, and the legitimate interests the restraint seeks to protect. Where the restraint is aligned with the employer’s proprietary interests (such as confidential design information), courts may be more receptive to enforcement against a former employee who joins a direct competitor within the restricted period.
