RULING

I have been asked to rule on the admissibility of the evidence the applicant seeks to lead from Professor Robert John Willis and Dr Chung-Hsing Yeh in relation to the carrying out, and the results, of their investigation of the two software systems in issue in this proceeding which investigation can be described generally as a pseudocode analysis.  The case has been opened by counsel for the applicant and at the conclusion of the opening counsel for the respondents submitted that I should rule on the admissibility of such evidence.  Counsel for the applicant submitted that I should defer the making of a ruling until the conclusion of the trial but having regard to the impact which the ruling may have on the future conduct of the trial particularly in relation to cross‑examination I consider it desirable to do so at this early stage.

The applicant seeks declaratory and injunctive relief and claims damages in relation to the software comprised in a series of computer programs known collectively as the Admar Winery System (“the Admar system”) which is designed for use in the wine industry.  The applicant claims to be the owner of the copyright subsisting in those programs which include the source code and object code of the programs.  The relevant version of the Admar system relied upon in the proceedings is the February 1993 version.

The fourth respondent was employed by…

CaseChat Overview and Summary

The case of Admar Computers Pty Ltd v Ezy Systems Pty Ltd involved a dispute over the alleged infringement of copyright and misuse of confidential information in the development of a wine industry software system. Admar Computers, the applicant, claimed that Ezy Systems and its associated respondents had used its confidential information and infringed its copyright in the Admar Winery System by developing the Ezy Wine Management System. The Federal Court of Australia was tasked with determining the admissibility of expert evidence from Professor Robert John Willis and Dr Chung-Hsing Yeh, who had conducted a pseudocode analysis of the two software systems. The court had to decide whether this evidence was relevant to the allegations of copyright infringement and misuse of confidential information.

The court ruled that the pseudocode analysis conducted by Professor Willis and Dr Yeh was not admissible in relation to the copyright infringement claim. The court held that copyright protection is afforded to the expression of a set of instructions in a computer program, not to the function or underlying logic of the program. The pseudocode analysis, which focused on the program logic and structure, did not demonstrate a substantial reproduction, publication, or adaptation of the Admar source code in the sense required by the Copyright Act. Therefore, it could not rationally affect the assessment of the probability of copyright infringement.

However, the court found that the pseudocode analysis was relevant to the claim of misuse of confidential information. The analysis showed that the Ezy system used similar program logic and design as the Admar system, which could indicate that the respondents had used the Admar source code in developing the Ezy system. This evidence was pertinent to determining whether the respondents breached their obligations of confidence by using the applicant’s confidential information.

In conclusion, the court ruled that the pseudocode analysis evidence was inadmissible on the issue of copyright infringement but was admissible in relation to the breach of confidence and misuse of confidential information claims. The decision highlighted the importance of distinguishing between the expression of a computer program, which is protected by copyright, and the underlying program logic, which is not.
