Electronic Tax-Free Shopping Ltd v Fexco Merchant Services

Electronic Tax-Free Shopping Ltd and Fexco Merchant Services were involved in a dispute regarding the validity of proposed amendments to a parent patent specification and a divisional patent specification. The matter was heard in the Federal Court of Australia. The primary legal issue before the Court was whether the proposed amendments to the parent and divisional specifications were allowable. This involved determining if the amendments were consistent with the original disclosure of the invention and whether they would enable a person skilled in the art to implement the invention as described.

The Court examined the evidence provided by witnesses, including their understanding of the invention, to assess whether the amendments would enable the skilled person to implement the invention. The Court noted that the evidence of each witness was relevant to the extent that it provided a basis for their opinion on whether the amended specifications would be sufficient for the skilled person. The Court determined that the proposed amendments did not sufficiently describe how the invention would operate in practice, and therefore, the amendments were not allowable. The Court found that the descriptions in the amended specifications did not provide enough detail to enable a person skilled in the art to implement the invention.

The Court further considered the context of the invention, which related to card payment systems in a multi-currency environment, and the specific details provided in the original specifications. It concluded that the proposed amendments failed to sufficiently address the technical aspects of the invention as required by patent law. Consequently, the Court ruled against the applicant, upholding the opposition to the amendments. The final orders required the parties to bring in agreed draft orders by a specified date to bring the appeal into readiness for hearing.
