Data Access Corporation v Powerflex Services Pty Ltd

“Copyright protects original expression, not business ideas.”

SHORT DESCRIPTION

The decision in Data Access Corporation v Powerflex Services Pty Ltd is a landmark ruling on the distinction between protectable expression and unprotectable ideas in copyright law. The High Court of Australia clarified that copyright does not extend to functional concepts, business logic, or abstract ideas embedded in computer software. Instead, protection is limited strictly to the original form of expression. This case remains a cornerstone for software copyright disputes worldwide.

FACTS OF THE CASE

Data Access Corporation developed a computer accounting software known as the “Dataflex” system. The software included a particular command structure and programming language designed to manage and manipulate databases efficiently. Powerflex Services Pty Ltd later developed a competing software product that adopted a similar command structure and operational logic, though the source code itself was independently written.

Data Access alleged that Powerflex had infringed its copyright by copying the essential structure and functionality of its software. It argued that the similarities in commands and system logic amounted to reproduction of a substantial part of its copyrighted work.

ISSUES INVOLVED

The primary issue before the Court was whether copying the functional aspects, command structures, and programming logic of software constitutes copyright infringement. The Court also examined whether copyright protection extends to ideas, methods of operation, and systems, or is confined only to the specific expression of those ideas.

ARGUMENTS OF THE PARTIES

Data Access contended that its software involved significant intellectual effort and that the structure of its programming language was an original literary work. It argued that Powerflex’s adoption of similar commands effectively appropriated the essence of its software.

Powerflex argued that copyright does not protect ideas or functional systems. It maintained that while both products performed similar functions, its source code was independently created and did not copy the actual expression found in Data Access’s software.

FINDINGS AND OBSERVATIONS OF THE COURT

The High Court ruled in favour of Powerflex and held that copyright protection does not extend to ideas, systems, or methods of operation. The Court emphasized the fundamental principle that copyright protects the form of expression, not the underlying idea or function.

It observed that allowing copyright over functional concepts would grant monopolies over ideas and hinder technological innovation. Since Powerflex had independently written its source code and had not copied the literal expression of Data Access’s program, no infringement had occurred.

SUGGESTION / PRACTICAL TAKEAWAY

This judgment is highly significant for software developers and technology companies. It confirms that competitors may develop functionally similar software as long as they do not copy the original source code or expression. Businesses seeking broader protection for functional innovations should rely on patents or contractual safeguards rather than copyright alone.

JUDGMENT

Year: 1999

The High Court of Australia held that copyright does not protect software ideas, command structures, or functional systems, and no infringement had occurred.
