A recent YouTube spat over an AI created cover of Britney Spears’ 2004 song “Toxic” demonstrates that AI has now made it possible for one artist to sing a cover of another artist, no human required! In this case, a group called DADABOTS, which describes itself as “a cross between a band, a hackathon team and an ephemeral research lab”, created the rendition using software enabling generation of audio content in the voice of a particular artist, in a particular genre or as a novel fusion. The end result was a Frank Sinatra cover of the Britney Spears song.

Whilst this is a prospect that is bound to be exciting to some, from the perspective of conventional copyright law (and perhaps defamation law), the path to creating such a custom cover track using AI is fraught with complexity and uncertainty.

Yet that didn’t stop DADABOTS rendition being met with something a little more conventional, a copyright takedown notice and subsequent removal from YouTube, as Futurism’s Dan Robitzski recently reported. Futurism noted that GreyZone Inc., a company which offers copyright infringement identification and reporting services, was responsible for the complaint but wasn’t able to identify on whose behalf.

Appeal of YouTube take down

The basis for the original takedown notice is unclear – presumably representatives of either Frank Sinatra or Britney Spears’ respective record labels took the view that their copyright was infringed in some form. In Australia, their songs are likely to be covered by a suite of copyright and related rights, potentially including copyright in the lyrics, the musical work, performance rights and recording rights.

In this case, DADABOTS appealed YouTube’s decision to remove the rendition, calling in aid the US copyright doctrine of fair use. This doctrine is codified in the US Copyright Act and allows “fair use” of copyright works without infringing copyright. Unlike in Australia where the equivalent “fair dealing” is limited to quite specific circumstances, the US Courts have a broad discretion to determine what use is “fair”, depending on factors such as the nature of the copyright work, the purpose of the use and the effect of the use on the potential market for the copyright work. YouTube accepted the appeal and DADABOTS upload was reinstated, albeit with YouTube flagging it as a cover of “Toxic”. YouTube offers a service which allows eligible copyright holders to set up rules dealing with any third party copies of their exclusive copyright content uploaded on YouTube. This might include blocking the uploaded media, taking ad revenue from it or tracking the viewership information. YouTube’s flag of the DADABOTS version presumably makes it subject to any such controls in place in respect of “Toxic”.

Use of copyright works during development of AI powered applications

To make the rendition, DADABOTS used an AI software tool developed by California based OpenAI. Known as “Jukebox”, the software utilises neural networks, a form of machine learning. To become competent, Jukebox was trained by processing various datasets, which in turn allowed it to create the rendition on the basis of what it learnt from that data processing. In this case Jukebox then performed lyrics (of “Toxic”) in the voice and/or genre of the artist on which the software had been trained (Frank Sinatra). According to Open AI’s website, Jukebox was trained on 1.2 million songs, corresponding lyrics and metadata, including artist, genre, year and associated keywords.

Interestingly, Futurism’s article suggests the YouTube appeal arguments were crafted without reference to the use of AI to create the DADABOTS rendition. The fair use arguments were focussed on the end result (i.e. the new rendition) as a fair use in itself, rather than by reference to the method used to create it. Separate to issues around copyright ownership of works created wholly or substantially by AI technologies, the use of copyright works for AI related functions, such as machine learning and datamining is very much a live issue globally. The extent to which such uses are thought to be “fair uses”, is likely to influence the development of the fair use doctrine in copyright, the bounds of which already vary considerably from country to country, if not lead to specific copyright provisions. One notable mover in this space is Japan, which from 1 January 2019 enacted various provisions in its Copyright Act aimed at exempting computer data processing and analysis of copyright works from infringement in certain circumstances. The way in which the law on this topic develops globally may well be a factor which influences where companies with a focus on developing AI powered applications choose to base themselves (if it is not already). Differences in the law on this topic around the globe may also lead to potentially complicated questions of jurisdiction where AI generated material is exported from one country to another.

In Australia, the current law is likely to be less friendly to machine learning and AI powered applications, as a result of the stricter confines on fair dealing, and other limited exceptions to copyright infringement. Certainly where AI applications are used for development which is commercial in nature, it is unlikely that Australian copyright exemptions would apply. While section 40 of the Copyright Act 1968 (Cth) does provide an exemption for fair dealing for research purposes, it has generally been given a narrow reach.

Indeed, extension of the fair dealing provisions in Australia was a topic considered extensively by the Productivity Commission in its review of intellectual property laws in Australia and consequent report issued in 2016. Submissions made on this issue included those from tech companies supporting a broader fair use exception and specifically referring to machine learning in this context. The Productivity Commission ultimately recommended significant reforms in this area paving the way for a US-style fair use exception. However following two years of further consultation, the Government announced in August 2020 only a limited extension of the fair dealing exceptions for non-commercial quotation.

As a consequence, use of datasets to train AI systems in Australia appears likely to carry with it a significant risk of copyright infringement for the foreseeable future, in the absence of an appropriate licence. As the law in this area continues to develop worldwide, this is clearly a space to watch for both copyright owners and anyone using databases of copyright material to power or utilise AI technologies.

Welcome to Shelston’s wrap-up of the most notable patent decisions in Australia and New Zealand delivered during 2019. It was a busy year for patent jurisprudence with some interesting themes emerging – in particular, it has been a banner year for decisions on the “manner of manufacture” requirement for patentable subject matter.

Read our full report

  • An expanded Full Federal Court clarified the “manner of manufacture” test for computer-implemented methods to be patentable (Encompass), a topic that was also central to several other Federal Court (TettmanRepipeWatson) and Patent Office (Apple) decisions.
  • There were also important “manner of manufacture” decisions in the life sciences space, with single judges finding both a diagnostic method involving a process of detecting genetic material (Sequenom) and use of genetic information to infer traits (Meat & Livestock Australia) to be patentable subject matter.
  • The Full Court confirmed there is no doctrine of patent exhaustion in Australia, the critical distinction being between repairs permitted by implied or express licence terms brought home to the purchaser of a product, and the impermissible re-making of the product beyond the scope of any licence (Calidad (No. 1)).
  • The Full Court confirmed that a permanent injunction framed in general form by reference to the claims of an infringed patent is generally appropriate and may be ordered in addition to a specific injunction describing products or conduct found to infringe (Calidad No. 2).
  • The Full Court overturned an award of additional damages for flagrant patent infringement on the basis that the infringer had believed, on objectively reasonable grounds, that its conduct did not infringe the patent (Oxworks).
  • The tide continued to turn against pharmaceutical patentees being granted interlocutory injunctions (MylanSanofi-Aventis).
  • Patentees learned some harsh lessons as the Full Court dismissed infringement claims based on the construction of the terms “contains” (construed exhaustively in Nichia) and “recognise” (construed broadly in Davies).
  • There were several applications by patentees to amend patent claims and specifications after commencing infringement proceedings (Meat & Livestock AustraliaNeurimBlueScope), with mixed success.
  • Consideration was given in the Patent Office to Australia’s “raised bar” requirements for support and sufficiency (Gary CoxUniversal Polymers).
  • Both clinical trial patient consent forms (InterPharma) and academic conference posters (Regeneron) were considered prior art documents in life sciences cases.
  • There were further decisions regarding families of patents that have been litigated for a decade or more (GlobaltechSNF).
  • There were also decisions regarding the admissibility of “WayBackMachine” evidence (Dyno Nobel), summary dismissal of an infringement case (Pilkin), a successful application for preliminary discovery (MMD), a failed cross-claim for unjustified threats (Liberation), a failed attempt to withdraw admissions relating to infringement (Juno), a “strawman” opponent to a patent application having to pay security for costs in an appeal despite winning the opposition (Toolgen) and a party commencing infringement proceedings despite not being a proper exclusive licensee having to pay indemnity costs (Vald).
  • Two recent decisions issued by the Intellectual Property Office of New Zealand provide new hope that, in certain circumstances, it may be possible to obtain an extension of time to file a divisional patent application (PrimapakMagic Leap).

As 2020 gets underway, we hope this provides a useful and practical resource and, of course, please do not hesitate to take the opportunity to contact our authors, all subject-matter experts in their respective fields, for advice on the issues raised by these important decisions.

This article relates to a decision of a single Judge of the Federal Court, which has since been appealed. An appeal decision of Full Court of the Federal Court of Australia was issued on 18 August 2021. The appeal decision can be accessed here: Hardingham v RP Data Pty Limited [2021] FCAFC 148.

The recent case of Hardingham v RP Data Pty Ltd [2019] FCA 2075 provides a good reminder of potential pitfalls for content creators who do not have express copyright licence arrangements in place, especially where the content is to be uploaded to third party websites by the party transacting with the creator or its sub-licensees.


Hardingham involved a claim for copyright infringement against the operator of online real estate analysis and information provider Core Logic (RP Data Pty Ltd) (RP Data) by a professional photographer, Mr Hardingham, and his company, Real Estate Marketing Australia Pty Ltd (REMA).

REMA, of which Mr Hardingham was the sole director, carried on the business of taking photographs, and creating floor plans, of properties at the request of real estate agencies for the purpose of those agencies advertising the properties for lease or sale.

Invoices were paid by agencies to REMA. There was no evidence of express copyright ownership or licensing provisions in place between REMA and the agencies. A key use of this content by agencies was to upload it to a widely used online property listing platform, realestate.com.au (operated by realestate.com.au Pty Ltd (REA)). Mr Hardingham and REMA were aware that this was one use for which their photography and associated services had been commissioned.

Amongst other things, the terms and conditions of REA’s realestate.com.au included an expansive express licence to REA over content uploaded by agencies, including a right to sub-license which also survived any termination of the user agreement between agencies and REA.

RP Data had a contract with REA. RP Data reproduced content generated by Mr Hardingham and uploaded by agencies to realestate.com.au on its own website corelogic.com.au.

The central question was whether RP Data had a licence to reproduce REMA’s content.

In 2014, the applicants’ solicitors initially wrote to RP Data alleging copyright infringement. RP Data’s solicitors disputed there was any infringement, citing the terms and conditions on realestate.com.au (in particular the copyright licence provisions which agencies uploading material had to agree to). The applicants next wrote to RP Data’s solicitors in 2018 (4 years later), recasting assertions of copyright infringement and making demands. The applicants commenced proceedings shortly afterwards.

The parties agreed that there would be an initial hearing and decision on a separate question, to be determined before all other issues in the proceeding. This separate question was whether copyright infringement could be established with respect to photographs and floorplans for 20 representative properties created by the applicants and supplied to agents, which in turn were supplied through to REA and then RP Data. The determination of the question of infringement regarding other properties, any pecuniary relief (damages or account of profits), and a cross-claim by RP Data against REA for contractual indemnification, was deferred.


Whilst the applicants accepted that the content Mr Hardingham generated was impliedly licensed to agencies for the purpose of marketing (with a right to sub-license), they argued that this licence was limited only “to use the photographs and floor plans for the limited purpose of marketing for sale or lease”. In particular, the applicants  contended the implied licence did not extend to use once the sale or lease of a property was completed. RP Data continued to reproduce the relevant content on its website after this time.

RP Data ran two alternative arguments:

  1. The agreement between REMA and the agencies contained an implied term that copyright would be assigned to the agencies when required by the agencies, and that as a result of this “equitable ownership”, “the agencies were entitled to and did grant a licence to REA… and to grant a sub-licence.”
  2. An express or implied licence had been granted by the applicants to the agencies, which in turn they had passed on to REA when agreeing to REA’s express terms and conditions for uploading content to realestate.com.au, and which REA had effectively then passed on to RP Data.

REA submitted that a basis for inferring or implying the necessary licence terms was “the way in which real estate properties were and are marketed to the public, including the internet by way of real estate agents’ websites, residential property portals (such as realestate.com.au) and social media platforms, where that marketing comprises current and historical listings in respect of the properties”.


In the absence of evidence indicating any formal written contract between the applicants and agencies, the Court noted that:

“it is important to understand the context in which the parties dealt with each other in order to form a view as to both: (a) what the terms of the contract were, including any terms inferred from conduct… and (b) what terms might be implied into that contract.”

Considering the evidence before it, the Court accepted that the evidence demonstrated that:

  • “the overwhelming majority of Australian real estate agencies use the realestate.com.au platform and, as a matter of practical commercial reality, would use the platform in marketing properties for sale or lease;
  • the prospect of selling or leasing a property is enhanced by using the realestate.com.au platform and the consequent exposure that provides;
  • one of the principal purposes for which the agencies commissioned photographs and floor plans from the applicants was to obtain works to upload to the realestate.com.au platform; and
  • whilst theoretically possible, at a practical level agencies are not able to negotiate out of the usual terms and conditions required by REA in order for the agencies to upload content to the realestate.com.au platform.”

The Court also observed that the applicants continued to work with agencies, despite at least since early 2014 having been on notice of the fact that agencies were uploading content to realestate.com.au and of the specific copyright licensing terms set out in REA’s terms and conditions on that website. Secondly, the applicants as well as agencies, knew photographs persisted on realestate.com.au even after a sale or lease was completed and also that within a few days of upload to REA’s website, these works would also appear on RP Data’s website pursuant to an agreement between REA and RP Data. Finally, the applicants set their fees for each of the properties for which they had generated content since 2014 in full knowledge of these facts and the applicants did not suggest that any of their content had ever been removed after upload from REA or RP Data’s websites.

Despite the absence of evidence as to whether the agencies had actually read the realestate.com.au terms and conditions, the Court observed that the applicants  “must have known that the works they had been commissioned to prepare had been and were being uploaded in accordance with terms and conditions imposed by REAThese were freely available on the realestate.com.au website”. The Court concluded that either as a result of the conduct and interactions between the applicants and the agencies, or due to a term implied in the agreement between the applicants and the agencies necessary for business efficacy:

“the applicants agreed that the agencies were authorised, by way of licence from the applicants, to upload the photographs and floor plans to the realestate.com.au platform and grant to REA a licence in the form required by REA and contained in REA’s usual terms and conditions.”

The Court concluded that equitable ownership of copyright by agencies which had commissioned the content from the applicants had not been established. A right for the agencies to call for an assignment was not necessary, because an implied licence would achieve business efficacy in the circumstances.


This case illustrates the determinative role frequently played by the prevailing commercial facts and arrangements in determining the scope of an implied copyright licence. Interestingly, ongoing publication of photographs and floor plans on realestate.com.au and corelogic.com.au was found to be so commonplace that the Court was prepared to find that the photographer always knew full well of the uses that would be made by the real estate agents, their sub-licensees (REA) and further sub-licensees (RP Data). This set of circumstances was fatal to the copyright owners’ claims, as they could not establish that their initial licence to the agents was limited to use during a sales campaign, when they knew such content remained on the realestate.com.au and corelogic.com.au platforms as part of historical sales data (e.g., in the “Sold” section).

In other cases, circumstances may be different such that a copyright owner may able to establish that the terms of an initial licence are more limited because the copyright owner had no actual or constructive knowledge of uses intended by its licensee.

Given the strong dependency of an implied licence on the surrounding factual matrix, and the consequent potential lack of certainty in its scope, this case serves as a reminder to copyright owners that clear express licence terms are preferable.
