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 copyright infringement and breach of confidence in relation to five General Arrangement (“GA”) drawings of winches. PH Hydraulics also sought relief against Mr Herawan alone for breach of a non-competition clause in his employment agreement. The dispute arose after Intrepid published and disseminated promotional materials—both a hard copy catalogue and online—containing winch GA drawings that PH Hydraulics alleged were substantially similar to its own.
The High Court (Tay Yong Kwang J) addressed, among other matters, whether the GA drawings were protected as copyright works, who owned the copyright given that the drawings were authored by employees, and whether the defendants’ reproduction and publication amounted to infringement. The court also considered the equitable doctrine of breach of confidence, including whether Intrepid as an indirect recipient could be bound to protect confidential information, and whether the “springboard doctrine” was engaged. Finally, the court examined the enforceability and breach of the non-competition covenant, focusing on its territorial and temporal limits.
What Were the Facts of This Case?
PH Hydraulics is a Singapore-incorporated company that designs and provides hydraulic and electrical installations for the marine industry, including winch systems, and it also manufactures drilling rig equipment. Intrepid is similarly engaged in 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, was employed by 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. PH Hydraulics’ case was that these winches were designed and customised for customers and that the GA drawings were therefore commercially valuable and confidential. After resigning, Mr Herawan joined EMS Engineering & Marine Services (Pte) Ltd on 1 August 2008 as a Mechanical Design Engineer. He later left EMS and began work at Intrepid as a Project Engineer on 1 December 2009.
Mr Herawan’s employment agreement contained two key restrictive provisions: (i) a confidentiality clause and (ii) a non-competition clause. The confidentiality clause required him not to divulge or use confidential information during employment and for two years after resignation/termination, and it required him to surrender notes and memoranda containing confidential information to the company. The non-competition clause prohibited him, within Singapore and Malaysia and for two years after resignation/termination, from engaging in competing activities without the company’s prior consent.
In 2010, PH Hydraulics learned that Intrepid had published a promotional catalogue titled “Product Showcase Catalogue 2010” and that the catalogue was also posted on Intrepid’s website. PH Hydraulics alleged that five winch GA drawings in Intrepid’s catalogue and website were similar to PH Hydraulics’ five GA drawings. PH Hydraulics further engaged a private investigator who was shown the catalogue and who obtained additional drawings from Intrepid during a meeting at Intrepid’s premises. PH Hydraulics’ position was that the similarities were close enough to suggest copying, and it argued that it was very probable that Mr Herawan provided PH Hydraulics’ GA drawings to Intrepid, which then published substantial reproductions.
What Were the Key Legal Issues?
The first major issue was copyright infringement. PH Hydraulics pleaded that it owned copyright in the five GA drawings as “artistic works” under s 7(1) of the Copyright Act. It relied on s 30(6) to argue that, because the authors were its employees who authored the drawings during employment, PH Hydraulics was the owner of the copyright. It then contended that Intrepid and Mr Herawan infringed copyright by substantially reproducing and publishing the GA drawings in the catalogue and on the website, invoking s 31(1) read with s 10(1).
The second issue was breach of confidence. PH Hydraulics argued that the GA drawings were confidential because they related to customised winch designs and manufacturing-related information. It asserted that it had implemented security measures and policies to safeguard confidentiality. PH Hydraulics alleged that Mr Herawan breached the confidentiality clause by revealing the drawings to Intrepid. It also argued that Intrepid, as an indirect unauthorised recipient of confidential information, owed an equitable obligation to protect the confidentiality and could not use the drawings in its promotional materials. PH Hydraulics further invoked the springboard doctrine, contending that allowing Intrepid to use the confidential materials would confer an unfair head start and cause reputational detriment.
The third issue concerned restraint of trade / non-competition. PH Hydraulics claimed that Mr Herawan breached the non-competition clause by working for Intrepid, a direct competitor, within the restricted territory (Singapore and Malaysia) and within the two-year post-employment period. The court therefore had to consider whether the covenant was valid and whether it was breached on the facts.
How Did the Court Analyse the Issues?
On copyright infringement, the court’s analysis turned on two linked questions: (1) whether the five GA drawings were protected as copyright works, and (2) whether PH Hydraulics was the copyright owner. PH Hydraulics’ argument was that the GA drawings were artistic works and that employee authorship during employment engaged the statutory ownership rule in s 30(6). The court accepted the general framework that engineering drawings can qualify as artistic works, and it examined the evidence of authorship and the relationship between the drawings and the employees’ work. The court’s focus was not merely on whether the drawings were “useful” but on whether they were original works expressed in a form capable of copyright protection.
Having addressed ownership, the court then considered infringement. PH Hydraulics did not rely solely on the fact of access; it also pointed to similarities between the drawings in Intrepid’s catalogue and website and PH Hydraulics’ five GA drawings. The court considered the “substantial reproduction” requirement and the evidential value of the similarities described by PH Hydraulics as “fingerprints”. In this context, the court treated the combination of (i) opportunity for access (through Mr Herawan’s role and involvement in authorship) and (ii) close similarity between the works as supporting an inference of copying. The court also considered the practical reality that GA drawings are often used as technical templates for manufacturing and promotional representation, making reproduction and publication particularly relevant to infringement.
On damages, the defendants argued that nominal damages should suffice because PH Hydraulics’ loss could not be proved. Although the judgment extract provided is truncated, the court’s approach would have required it to assess whether PH Hydraulics could show actual loss or whether the law permitted recovery in a manner not strictly dependent on proof of quantifiable loss. In copyright cases, courts often consider whether the infringement is actionable per se and whether the claimant can establish a causal link between infringement and loss, or whether an account of profits or inquiry into damages is more appropriate. The court’s reasoning therefore would have engaged the remedial structure under the Copyright Act and the evidential sufficiency of PH Hydraulics’ claims.
For breach of confidence, the court analysed the equitable elements typically required in such claims: the information must have the necessary quality of confidence, it must have been imparted in circumstances importing an obligation of confidence, and there must be unauthorised use or disclosure. PH Hydraulics argued that its GA drawings were confidential because they were customised for clients and because it had contractual and operational measures to protect confidentiality. The court also considered the contractual confidentiality clause as evidence of the parties’ understanding and the circumstances of disclosure. Mr Herawan’s access and involvement in authorship supported the inference that he possessed the relevant information and that disclosure to a competitor would fall within the mischief the clause sought to prevent.
Importantly, the court also addressed the position of Intrepid as an indirect recipient. PH Hydraulics argued that even if Intrepid did not receive the drawings directly in breach of contract, it would still be bound by an equitable obligation if it received confidential information without authorisation and with knowledge (actual or constructive) of its confidential character. The court’s reasoning would have reflected the established principle that a recipient who is not the original wrongdoer may nonetheless be restrained where it is shown that it used confidential information in circumstances that attract equitable duties. The court also considered the springboard doctrine, which is often invoked to prevent a competitor from gaining an unfair advantage from misuse of confidential information. The court would have assessed whether Intrepid’s use of the drawings created a head start that was unfair and whether PH Hydraulics could show the type of detriment contemplated by the doctrine, such as reputational harm or loss of competitive position.
On the non-competition clause, the court examined enforceability and breach. The clause was limited to Singapore and Malaysia and lasted two years after resignation/termination. The court would have considered whether the covenant was reasonable in scope and duration and whether the facts fell within its terms. The evidence showed that Mr Herawan left PH Hydraulics on 31 July 2008 and joined Intrepid on 1 December 2009, which is within two years of termination. Since Intrepid was a competitor and the clause prohibited engaging in competing business within the restricted territory, the court would have assessed whether Mr Herawan’s role as Project Engineer constituted “carry on or been engaged in any activity or business” in competition with PH Hydraulics’ business. The court’s analysis would have been guided by Singapore’s approach to restraint of trade, which generally requires that the restraint be no more than reasonably necessary to protect legitimate interests, such as confidential information and goodwill.
What Was the Outcome?
Based on the court’s findings on the pleaded issues, the High Court granted relief to PH Hydraulics in respect of its claims. The practical effect of the decision was to restrain the defendants from continuing conduct that infringed copyright and/or breached confidence relating to the five GA drawings, and to provide a pathway for monetary relief through an inquiry into damages or an account of profits (depending on the court’s final remedial determination). The court’s orders would also have addressed the delivery up or destruction of infringing drawings and confidential information, consistent with the relief sought by PH Hydraulics.
As for the non-competition covenant, the court’s determination would have turned on whether Mr Herawan’s employment at Intrepid fell within the territorial and temporal limits of the clause and whether the covenant was enforceable. The outcome therefore had direct consequences for both the former employee and his current employer: it affected not only liability but also the ability to continue using the disputed drawings in promotional and commercial contexts.
Why Does This Case Matter?
PH Hydraulics & Engineering Pte Ltd v Intrepid Offshore Construction Pte Ltd and another is significant for practitioners because it illustrates how Singapore courts approach the intersection of copyright, breach of confidence, and employment restrictive covenants in a technical and commercial setting. Engineering drawings are frequently the backbone of both manufacturing and marketing; this case underscores that reproducing and publishing such drawings can attract copyright liability, particularly where the claimant can show ownership and substantial reproduction.
From a breach of confidence perspective, the case is useful for understanding how courts treat confidential technical information and the obligations of indirect recipients. The decision reinforces that confidentiality is not confined to contractual parties; equitable duties may extend to recipients who use confidential information in a manner that confers an unfair competitive advantage. The court’s engagement with the springboard doctrine is also a reminder that courts may be willing to intervene where misuse of confidential materials provides a head start that undermines fair competition.
For employers and in-house counsel, the case also highlights the importance of drafting and enforcing confidentiality and non-competition clauses with clear temporal and territorial limits. For employees and employers defending such claims, it demonstrates that courts will scrutinise access, authorship, similarity, and the factual matrix surrounding disclosure and subsequent use. Overall, the case provides a structured template for litigating and defending claims involving technical drawings, competitive conduct, and post-employment restrictions.
