Data Access Corporation v Powerflex Services

Data Access Corporation (the appellant) appealed to the High Court of Australia against a decision of the Full Federal Court which had affirmed the primary judge's finding that Powerflex Services (the respondent) had infringed Data Access's copyright in its software. The dispute concerned the respondent's use of the appellant's software, specifically its "DataFlex" database management system, in a manner that the appellant alleged constituted copyright infringement.

The High Court was required to determine whether the respondent's actions amounted to an infringement of the appellant's copyright in the DataFlex software. This involved considering whether the respondent had made an unauthorised "copy" of the software, as defined by the Copyright Act 1968 (Cth), and whether the respondent's use of the software was within the scope of any licence granted by the appellant. A key issue was the interpretation of the licence agreement and whether it permitted the respondent to use the software in the manner it did.

The Court analysed the nature of the appellant's copyright in the DataFlex software, which was a compilation of computer programs. It considered the distinction between the copyright in the program itself and the copyright in the output generated by the program. The majority of the Court found that the respondent had not made an unauthorised copy of the DataFlex software in the sense contemplated by the Copyright Act. They reasoned that the respondent's use of the software, which involved running the programs to generate output, did not constitute the creation of a reproduction of the copyright work. The Court emphasised that copyright protects the expression of ideas, not the ideas themselves, and that the respondent was not reproducing the code or structure of the DataFlex programs.

The appeal was allowed, and the orders of the Full Federal Court were set aside. The High Court ordered that the respondent's appeal to the Full Federal Court be dismissed, meaning the primary judge's decision finding infringement was overturned.
