Summary
PH Hydraulics & Engineering Pte Ltd (“PH Hydraulics”) brought proceedings against its former employee, Mr Rinov Herawan, and his subsequent employer, Intrepid Offshore Construction Pte Ltd (“Intrepid”), alleging that Intrepid had infringed PH Hydraulics’ copyright and breached contractual/confidential obligations by using and publishing PH Hydraulics’ winch general arrangement (“GA”) drawings. The dispute centred on five specific GA drawings relating to customised winch systems used in the marine industry. PH Hydraulics also alleged that Mr Herawan breached a non-competition clause in his employment agreement by joining Intrepid, a competitor.
The High Court (Tay Yong Kwang J) addressed the intertwined questions of (i) whether the five GA drawings were protected as copyright works and whether PH Hydraulics owned the copyright, (ii) whether Intrepid’s publication and reproduction amounted to copyright infringement, (iii) whether the drawings were confidential and whether there was a breach of confidence by the defendants, and (iv) whether the non-competition clause was enforceable and, if so, whether it was breached. The court’s reasoning reflects a careful approach to proving access, similarity, authorship/ownership, and the contractual and equitable principles governing confidential information and restraint of trade.
What Were the Facts of This Case?
PH Hydraulics is a Singapore-incorporated company that designs and supplies hydraulic and electrical installations, including winch systems, for the marine industry. It also manufactures drilling rig equipment. Intrepid is also a Singapore-incorporated company providing and manufacturing hydraulic and electrical installations such as winch systems. The two companies were undisputed competitors 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 as a Mechanical Design Engineer on 1 August 2008. He later left EMS and joined Intrepid as a Project Engineer on 1 December 2009.
PH Hydraulics’ case was that the five GA drawings were specially designed and customised for customers, and that the drawings were therefore confidential. The five 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 alleged that Mr Herawan 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 hard copy promotional catalogue titled “Product Showcase Catalogue 2010” and that the catalogue was also published on Intrepid’s website. The catalogue contained five winch GA drawings (“the infringing drawings”) which PH Hydraulics said were similar to its five GA drawings. PH Hydraulics also engaged a private investigator who was shown the catalogue bearing the infringing drawings and who obtained additional drawings from Intrepid during a meeting at Intrepid’s premises. PH Hydraulics alleged that at least three of those additional drawings were similar to PH Hydraulics’ winch drawings.
What Were the Key Legal Issues?
The first major issue was copyright infringement. PH Hydraulics pleaded that its five GA drawings were protected as “artistic works” under section 7(1) of the Copyright Act. It relied on section 30(6) to contend that because the authors were its employees who authored the drawings during employment, PH Hydraulics owned the copyright. PH Hydraulics further argued that Intrepid had substantially reproduced and published the drawings in its catalogue and on its website, which would constitute infringement under section 31(1) read with section 10(1).
The second issue concerned breach of confidence. PH Hydraulics argued that the GA drawings were confidential because the winch designs were customised for customers and because PH Hydraulics had security measures and policies to safeguard confidentiality. It alleged that Mr Herawan breached the confidentiality clause in his employment agreement by revealing the drawings to Intrepid. PH Hydraulics also argued that Intrepid, as an indirect unauthorised recipient, owed an equitable obligation to protect the confidentiality and could not use the drawings in its catalogue and website. PH Hydraulics further invoked the “springboard doctrine”, contending that allowing Intrepid to use the drawings would give it an unfair head start and cause reputational detriment if customers believed Intrepid created the designs.
The third issue related to restraint of trade. PH Hydraulics sued Mr Herawan alone for breach of a non-competition clause in his employment agreement. The clause prohibited him, within Singapore and Malaysia, for two years after resignation/termination, from engaging in any activity or business competing with PH Hydraulics’ business without the company’s prior consent. The court therefore had to consider whether the clause was enforceable and whether the facts showed a breach.
How Did the Court Analyse the Issues?
The court’s analysis of copyright began with ownership and authorship. PH Hydraulics’ position was that the drawings were created by its employees during employment, so it owned the copyright under section 30(6) of the Copyright Act. The defendants did not concede ownership; they disputed that the GA drawings were the original work of PH Hydraulics’ employees at the relevant time. This dispute required the court to examine the evidence on authorship and the link between the employees’ work and the drawings in question. In copyright disputes involving technical drawings, the court’s focus typically includes whether the work is original, whether it qualifies as an artistic work, and whether the claimant can establish ownership through the statutory employee-authorship rule.
On infringement, the court considered whether Intrepid had reproduced and published the drawings. The extract indicates that the defendants did not appear to deny substantial reproduction in the catalogue and on the website. The contest therefore largely turned on whether PH Hydraulics could prove that it owned the copyright and whether the drawings were protected works. PH Hydraulics sought to establish infringement through a combination of access and similarity: it argued that Mr Herawan had ample opportunity to access the five GA drawings and that there was close similarity between PH Hydraulics’ drawings and Intrepid’s catalogue drawings. PH Hydraulics also pointed to “fingerprints” (observable distinctive features) and argued that it was very probable that Mr Herawan provided the drawings to Intrepid, which then published a substantial reproduction.
The court also had to address the defendants’ pleaded defence of “industrial application” (sometimes discussed in copyright contexts where drawings are used to manufacture articles). Although the defendants did not pursue this defence in closing submissions, its presence in the pleadings shows that the parties were alive to the statutory boundaries between copyright in drawings and the manufacture of industrial articles. In practice, courts distinguish between the artistic work embodied in drawings and the functional or industrial use of those drawings, and they consider whether the statutory scheme protects the drawing itself regardless of whether it is used to produce products.
On breach of confidence, the court’s reasoning would have been anchored in both contractual and equitable principles. PH Hydraulics relied on the express confidentiality clause in the employment agreement. The clause required the employee not to divulge or use confidential information during employment and for two years after resignation/termination, except in the proper course of duties. It also required surrender of notes and memoranda containing confidential information at termination or on request. The clause further provided that the restriction would cease to apply to confidential information that entered the public domain without breach or misfeasance.
PH Hydraulics emphasised that the GA drawings were confidential because they were customised for clients and because PH Hydraulics had security measures and policies. It argued that Mr Herawan breached the confidentiality clause by revealing the drawings to Intrepid. PH Hydraulics also argued that Intrepid, as an indirect recipient, could not treat the information as freely usable once it was obtained improperly. The court therefore had to consider whether the information was indeed confidential (not public), whether it was imparted in circumstances giving rise to an obligation of confidence, and whether there was unauthorised use. The springboard doctrine was relevant to the remedy analysis: even where the defendant’s conduct is not a direct theft in the criminal sense, equity may restrain use of confidential information to prevent an unfair competitive advantage gained by the misuse of confidential know-how.
Finally, the restraint of trade issue required the court to consider the non-competition clause’s enforceability and scope. The clause was geographically limited to Singapore and Malaysia and temporally limited to two years. PH Hydraulics argued that the restriction was valid and that Mr Herawan breached it by working for Intrepid, a direct competitor, within the restricted period and territory. The court would have assessed whether the clause went no further than necessary to protect legitimate business interests (such as confidential information and goodwill) and whether it was reasonable in duration and geographic scope. In Singapore, restraint of trade clauses are generally enforceable only if they are reasonable and protect legitimate interests; otherwise, they may be struck down or limited.
What Was the Outcome?
Based on the court’s findings on copyright ownership, infringement, breach of confidence, and the restraint of trade clause, the High Court granted relief to PH Hydraulics. The practical effect of the decision was to restrain the defendants from continuing the infringing and confidentially improper use of the five GA drawings and to provide remedies consistent with the court’s conclusions on infringement and breach.
The court also addressed damages and/or accounts of profits and the appropriate form of injunctive relief, including orders relating to delivery up or destruction of infringing drawings and confidential information, as sought by PH Hydraulics. For the second defendant, the court’s determination on the non-competition clause translated into liability for breach of the employment agreement, with consequences in damages as pleaded.
Why Does This Case Matter?
This case is significant for practitioners because it illustrates how Singapore courts approach the overlap between copyright protection of technical drawings and contractual/equitable protection of confidential information. For employers in engineering and design-intensive industries, the decision underscores that GA drawings and similar technical documents can be treated as copyright works and, separately, as confidential information, depending on the evidence of originality, authorship, confidentiality, and unauthorised use.
From a litigation strategy perspective, the case highlights the evidential importance of access and similarity in copyright infringement claims. Where direct proof of copying is difficult, claimants often rely on circumstantial evidence such as the employee’s access to the drawings, the timing of the defendant’s publication, and distinctive similarities (“fingerprints”). The court’s willingness to consider such evidence is particularly relevant for disputes involving design documentation and promotional materials.
For employment and restraint of trade matters, the case also demonstrates that non-competition clauses will be analysed for reasonableness and legitimate protection. Even where a clause is limited in time and geography, enforcement will depend on the court’s assessment of whether the clause is justified by the employer’s legitimate interests and whether the employee’s post-employment conduct falls within the prohibited scope. Practitioners drafting restrictive covenants should therefore ensure that the clause is tailored to protect specific interests, such as confidential information and competitive advantage, rather than operating as an overly broad prohibition on work.
