Watson Webb Pty Ltd v Comino

This case came out of a commercial relationship in the water distribution products sector that broke down and then turned into broad Federal Court litigation. The parties were involved in valves, water meter assemblies and brackets. The Court’s introduction makes clear that the dispute was not confined to one product or one legal right. It spread across registered designs, copyright in technical drawings, breach of confidence, contract, misleading conduct under the Australian Consumer Law and patent validity.

The central practical story was about a valve drawing called the C9746 design drawing. The Court described it as a drawing of a valve with a lockable handle and an internal thread. According to the Court’s introductory findings, that drawing was later provided by the respondents, wholly or in substantial part, to Infinity Design in February 2018, to their patent attorney for the purpose of registering designs, and then to the Designs Office through that attorney. Mr Comino was recorded on the Australian Designs Register as owner of two registered designs, numbered 201811005 and 201811810.

AVI and Cimberio challenged that position. They contended that Cimberio was at least a co-designer of the registered designs and that rights held by Mr Comino in the designs were held on constructive trust for Cimberio. At the same time, Mr Comino and Strongcast alleged that AVI’s own valves and associated water meter assemblies infringed the registered designs, and that AVI also infringed an innovation patent concerning brackets used for holding pipes. The result was a large, overlapping dispute about who created what, who owned what, what could be used for what purpose, and what relief should follow.

The Court had to decide a cluster of connected issues arising from the same dealings. On the design side, one major question was entitlement. The Court had to determine whether Mr Comino alone was entitled to be recorded as owner of the 005 and 810 designs, or whether Cimberio was also an entitled person because it was at least a co-designer. The catchwords show that this involved questions about identification of a co-designer, whether the first respondent was the only person whose mind conceived the relevant visual features, and whether first reduction to visible form could occur through multiple documents created on different occasions.

The Court also had to deal with design validity and infringement issues. It considered whether the designs were new or distinctive over the prior art base, whether confidential material formed part of that prior art base, and whether AVI’s products were identical to or substantially similar in overall impression to the 810 design. There was also a separate issue about whether a letter sent on behalf of Mr Comino in February 2020 amounted to an unjustified threat under the Designs Act or was merely a notification.

On the copyright side, the Court had to decide whether copyright subsisted in the C9746 design drawing, whether Cimberio owned that copyright, whether the respondents reproduced or published the drawing, whether any implied licence existed, and whether the respondents authorised infringement by Infinity Design. The extract also shows the Court considered the interaction between copyright and design law, including overlap issues.

On the equitable and consumer law side, the Court had to determine whether the C9746 drawing had the necessary quality of confidence, whether it was received in circumstances importing an obligation of confidence, whether that obligation was breached, and whether the respondents engaged in misleading or deceptive conduct under section 18 of the ACL. The ACL issue included alleged representations by silence about how the drawing would be used. Finally, the Court had to decide whether claims 1 to 4 of the 757 innovation patent were valid and, if valid, whether AVI infringed them.

Justice Halley’s introductory findings set out the headline outcomes. First, the Court concluded that Cimberio was at least a co-designer of the 005 and 810 designs and was an entitled person at the time each design was registered. That is a significant finding for any business that assumes the person named on the register is automatically the sole owner in substance as well as form.

Second, the Court concluded that both designs were distinctive over the design of the C6827 valve, which the extract describes as the valve provided by AVI to Strongcast and sourced by AVI from Cimberio. In other words, the designs were not defeated on the prior art argument identified in the extract. But that did not end the entitlement dispute or the relief issues.

Third, the Court found that AVI’s ball valves were not identical to, or substantially similar in overall impression to, the 810 design. That meant the respondents’ design infringement case against AVI failed. The Court also found that the 28 February 2020 letter sent by Foundry Intellectual Property Pty Ltd on behalf of Mr Comino did not constitute an unjustified threat under section 77 of the Designs Act.

Fourth, on copyright, the Court found that the respondents directly infringed Cimberio’s copyright in the C9746 design drawing by providing it, wholly or in substantial part, to Infinity Design in February 2018, to their patent attorney for the purpose of registering the designs, and by their patent attorney, as their agent, to the Designs Office. The Court also found that the respondents authorised Infinity Design’s infringement of that copyright.

Fifth, on breach of confidence, the Court found that the respondents breached obligations of confidence owed to Cimberio by disclosing the C9746 design drawing to Infinity Design, to their patent attorney for design registration purposes, and to the Designs Office through that attorney, and by using it for an extraneous purpose. On contract, however, the Court found that the written Product Distribution Agreement dated 16 July 2013 did not extend or apply to the C9746 design drawing, so the breach of contract and inducing breach of contract claims did not succeed.

Sixth, on the ACL, the Court found contraventions of section 18. The extract states that the respondents made representations to the effect that they would only use the C9746 design drawing for the purpose of signing off the drawing prior to manufacture by Cimberio and would not apply for a design registration in respect of the C9746 valve or use the drawing for that purpose. The Court found those contraventions established.

Finally, on the patent dispute, the Court held that claims 1 to 4 of the 757 innovation patent were invalid and should be revoked because each lacked clarity, support and or sufficiency under the Patents Act. The Court also said that, even if the patent had otherwise been valid, AVI did not infringe it by supplying the relevant brackets or water meter assemblies.

The relief position is important because it shows how serious the consequences of misuse of drawings and disputed design entitlement can be. The Court said Cimberio was entitled to an order for an account of profits or, subject to election, damages for the respondents’ copyright infringement. It also said Cimberio was entitled to additional damages under the Copyright Act. On the design side, the Court said an order was to be made revoking the registration of each of the designs, and a declaration was to be made that each of Cimberio and Mr Comino was an entitled person in respect of each design at the time it was registered.

The Court also said a declaration was to be made that Mr Comino held his interest in the designs on constructive trust in favour of Cimberio and that an order should be made transferring that interest to Cimberio. In addition, the applicants were said to be entitled to damages and or compensation under sections 236 and or 237 of the ACL for loss suffered by reason of the section 18 contraventions. The Court further said the 757 patent was invalid and should be revoked.

But the extract also makes clear that not everything was finalised on 30 July 2025. The parties were ordered to provide agreed or competing draft orders giving effect to the reasons by 14 August 2025, and the matter was listed for case management on 18 August 2025 to resolve outstanding issues in relation to orders and costs. In the substantive proceeding, the 18 August 2025 hearing was also to deal with directions for determination of quantum and any remaining issues about orders. The extract expressly states that quantification of the account of profits or damages, additional damages under the Copyright Act, and damages and or compensation under the ACL would be determined at a later hearing.

That means this decision is highly useful for understanding liability findings and the broad shape of relief, but it should not be read as a final statement of the exact monetary outcome. It also means that the transfer-related and constructive trust findings should be read together with the fact that the final form of orders was still to be settled after the reasons.

The strongest practical message from this case is that product-development documents need a clear chain of title and a clear permitted-use framework. If your business receives a drawing from a supplier, manufacturer, consultant or collaborator, you should not assume that possession of the drawing means freedom to use it for any later purpose. The Court’s findings show that using a drawing to brief a designer, instruct a patent attorney or support a design filing can create separate copyright, confidentiality and ACL exposure.

This case also shows that design registration strategy should start with entitlement, not just novelty. A business may think it has improved a product enough to justify filing a design application, but if the design emerged from collaborative work or from supplier-originated drawings, the filing party may not be the only entitled person. That can lead to declarations, revocation, transfer-related relief and expensive satellite disputes about ownership.

Another practical point is that losing on one IP theory does not remove risk under another. Here, the respondents failed on their design infringement case against AVI, but AVI and Cimberio still succeeded on copyright, confidence, ACL and patent invalidity issues. Businesses should therefore assess all rights in play, not just the right they think is strongest.

The ACL findings are also commercially important. The extract indicates that the Court accepted representations by silence or conduct about limited use of the drawing and no intention to apply for design registration. That is a reminder that risk can arise not only from express written statements, but also from what a business conveys through its conduct in a collaborative project.

In practical terms, businesses should document who created each drawing and each revision, who owns copyright in those materials, whether the information is confidential, what uses are permitted, whether any design application will be filed, and whether the filing will be in one party’s name, jointly, or only after an assignment. Internal teams should also make sure external designers, patent attorneys and product managers are working from the same rights position before any filing or launch occurs.
