Inducing another party to breach a contract – a rare but available cause of action

Inducing a breach of contract is a rarely used but available cause of action in Australian common law. The recent case of Sealed Air Australia Pty Limited v Aus-Lid Enterprises Pty Ltd [2020] FCA 29, involving an entity inducing a party to breach an existing binding patent licence agreement, tested this cause of action and reminds us of the availability and extent of such a claim.


Aus-Lid Enterprises (Owner) was the registered owner of Patent AU754978 (Patent) – a patent for a yoghurt container lid containing a built-in spoon. Aus-Lid Operations (Licensee) was the exclusive licensee of the Patent. In January 2011, the Licensee contracted with Sealed Air Australia Pty Limited (Sealed), granting Sealed an “irrevocable, exclusive sub-licence” to exploit the Patent for pre-packaged dairy products in Australia and New Zealand (Patent Licence). Pursuant to the Patent Licence, Sealed began supplying the patented lids to Chobani, and remained as the exclusive supplier until about mid-2014.

In mid-2014, Visy Packaging Pty Ltd (Visy) began to manufacture and sell the patented lids to Chobani. This was done pursuant to an in principle agreement between Visy and the Licensee. Sealed noticed a reduction in the number of lids it was supplying to Chobani. By March 2015, Visy had replaced Sealed as the sole supplier of the patented lids to Chobani.

In July 2014, Sealed’s lawyers wrote to the Licensee, demanding that the Licensee revoke any rights it had granted to Visy on the basis that this was in breach of the Patent Licence. The Licensee refused, alleging that Sealed had breached the Patent Licence first.

In September 2014, Sealed’s lawyers wrote to Visy directly, informing Visy of the “irrevocable, exclusive sub-licence”, and subsequently provided Visy with a copy of the Patent Licence itself. In December 2014, the Licensee and Visy purported to formalise their agreement by entering into an Intellectual Property Agreement, whereby the Licensee agreed to grant Visy a non-exclusive licence to exploit the Patent.

Sealed commenced proceedings against Visy, suing for damages on the basis of the tort of inducing breach of contract.


The Federal Court confirmed the requirements of the inducing breach of contract tort as being:

  • contract – there must be a contract between the plaintiff (Sealed) and a third party (the Licensee)
  • knowledge – the defendant (Visy) must know that the contract exists and that if the third party (the Licensee) does, or fails to do, a particular act, that conduct would be a breach of contract
  • intention – the defendant (Visy) must intend to induce or procure the third party (the Licensee) to breach the contract by doing or failing to do that particular act
  • loss or damage – the breach must cause loss or damage to the plaintiff (Sealed).

In essence, Sealed claimed that:

  • Visy had known of the existence of, and the irrevocable and exclusive terms of, the Patent Licence
  • Visy had known that the granting of rights by the Licensee to Visy to exploit the Patent was in breach of the Patent Licence
  • Visy intended to induce and procure the Licensee to engage in this breach by paying the Licensee royalties to exploit the Patent
  • the breach caused loss or damage to Sealed in the loss of its business of supplying the patented lids to Chobani.


Visy submitted that:

  • it had not been confident that it had understood the status and enforceability of the Patent Licence. This was most important based on representations from a director of the Licensee, Mr de Souza, to the General Counsel at Visy that Sealed had previously repudiated the Patent Licence and that the Licensee was therefore no longer prohibited from granting Visy the right to exploit the Patent
  • it was unsure whether the Licensee was in breach of the Patent Licence by granting Visy rights to exploit the Patent.

Based on the letter from Sealed’s lawyers to Visy in September 2014, the Court found that Visy was aware of the Patent Licence and knew that it contained terms to the effect of an irrevocable and exclusive sub-licence. This knowledge was sufficient to ground an intention on Visy’s part to procure the Licensee’s breach of the Patent Licence.

The Court stated that even if this was incorrect, it was sufficient if Visy had deliberately disregarded, or been wilfully blind or recklessly indifferent to, the fact that the Licensee was in breach of the Patent Licence. The Court determined that this was the case. Visy had relied on Mr de Souza’s representations without obtaining any independent legal advice about the status or enforceability of the Patent Licence (or without undertaking any other due diligence more generally). Importantly, the Court found that this had been intentionally done to align with Visy’s commercial interests of continuing to manufacture and supply the patented lids to Chobani.

A defence to the tort of inducing breach of contract is where there is a reasonable, bona fide belief that a party’s conduct does not induce a breach of contract – for example, where the party has a reasonable bona fide belief that the relevant contract is no longer on foot. This reasonableness is to be assessed by a reference to a person in the position of the defendant. The Court found that this defence was not applicable in this case. While Mr de Souza had represented that Sealed had previously repudiated the Patent Licence, the Court found that, for an experienced lawyer such as the General Counsel at Visy, this did not represent a basis for a reasonable, bona fide belief that the Patent Licence was no longer effective. There had been no further investigations from Visy in relation to the alleged repudiation, and the Licensee had never made any representation that any such repudiation had been accepted or that the Patent Licence had been terminated.

On the basis of the Court’s finding that Sealed would have remained as the supplier of the patented lids, but for the breach induced by Visy, the Court ordered Visy to pay Sealed damages of over $1.6 million for lost profits. The calculation was based on Visy’s gross profits from manufacturing and supplying the lids from the time Visy became aware of Sealed’s rights under the Patent Licence in September 2014, up until the expiration of the Patent Licence.

Key takeaways

This case illustrates the importance of undertaking detailed due diligence and all reasonable enquires before entering into any commercial transaction. In the event that any red flags appear, either in the pre-bid, bid or project stage, the onus will be on that party to seek independent legal advice to understand its position and take any appropriate next steps. Failure to do so may expose that party to the risk of liability for breach of a third party contract.
